Ex.No: CREATION OF A BPEL MODULE AND A COMPOSITE

Date: APPLICATION

AIM:

To Create a SOA project with BPEL Module To Compose A Web Service.

PROCEDURE:

STEPS TO CREATE A BPEL MODULE

Creating a new BPEL Module Project

The following sections use the Synchronous sample project, and provide step-by-step directions

for creating a simple BPEL module project, using the Synchronous sample project.

To Create a BPEL Module Project

1. In the NetBeans IDE, choose File > New Project.

The New Projects wizard appears.

2. Under Categories, select Service Oriented Architecture.

3. Under Projects, select BPEL Moduleand click Next.

and specify the project location or accept the defaults.

5. Click Finish.

The Projects window now contains a project node for the BPEL Module project.

Creating a BPEL Process Using the BPEL Designer

Now that you have created your XML Schema and WSDL Document, you can create your BPEL

process.

To Create the BPEL Process



31

1. In the Projects window, expand your BPEL module project node, right-click the Process

Files node, and choose New -> BPEL Process.

The New BPEL Process dialog box appears.

a. In the Projects window, expand your project's Process Files node and select the

.wsdl file (Synchronous.wsdl for this example).b. Drag the WSDL file from the Projects window to the left side of the Design view

canvas.

The IDE provides visual prompts to show you where you can drop the selection.

The BPEL Editor adds a partner link to the canvas.



33

4. Add a Receive activity to the BPEL Process.

a. From the Web Service section of the Palette window, select the Receive activity.

b. Drag the Receive activity to the HelloWorldProcess process box in the Design

view canvas, between the Process Start and the Process End activities.The Receive1 activity is added to the process box.

c. Click the Receive1 activity's Edit icon.

The Receive1 Property Editor appears.

d. On the Main tab, change the value in the Name field to start.e. From the Partner Link drop-down list, choose PartnerLink1.

f. Click the Create button next to the Input Variable Field.

The New Input Variable dialog box appears.

g. Click OK to accept the default values.

h. Click OK to close the Receive1 Property Editor.

The Design view displays the new connection between PartnerLink1 and the Start activity in the

process box.



34

5. Add a Reply activity to the BPEL Process.

a. Select the Reply activity in the Web Service section of the Palette. Drag and dropthe Reply to the prompt between the Start activity and the Process End activity in

the process box on the design view canvas.

A Reply1 activity is added to the design view canvas.

c. On the Main tab, change the value in the Name field to End.d. From the Partner Link drop-down list, choose PartnerLink1.

The IDE populates the Operation field with NewWSDLOperation.

e. To create anew output variable, make sure that Normal Response is selected, and

click the Create button next to the Input Variable Field.

The New Input Variable dialog box appears. Click OK to accept the default values.

f. Click OK to close the Reply1 Property Editor.

The Design view displays the new connection between the End activity in the process box and

PartnerLink1.



35

6. Add a Assign activity to the BPEL Process.a. Select the Assign activity in the Basic Activities section of the Palette. Drag and

drop the Assign to the prompt between the Start activity and the End activity in

the process box on the design view canvas.

The Assign1 activity is added to the design view canvas.

b. Select the Assign1 activity and click the Mapper button on the editors toolbar.

The BPEL Mapper appears.

c. Map the paramA node under Variables -> NewWSDLOperationIn -> inputType

in the Output pane of the BPEL Mapper, to the paramA node under Variables ->

NewWSDLOperationOut -> resultType in the Input pane of the Mapper. To dothis, select theparamA node under Variables -> NewWSDLOperationIn ->inputType in the Output pane, and drag your cursor to the paramA node under

Variables -> NewWSDLOperationOut -> resultType in the Input pane.

This assignment copies the input statement into the output.



36

7.

To save your changes click the Save All icon in the IDE menu bar.Creating a Composite Application Project

A BPEL Module project is not directly deployable. You must first add a BPEL Module project,

as a JBI module, to a Composite Application project. You can then deploy the Composite

Application project. Deploying the project makes the service assembly available to the

application server and enables its service units to run.

To Create a New Composite Application Project

1. Choose File > New Project (Ctrl-Shift-N).

2.

In the Categories list choose Service Oriented Architecture, in the Projects list chooseComposite Application, and click Next.

3. In the Name and Location page, change the project name to HelloWorldApplication, and

specify the location of project files.4. To set the new Composite Application the main project as main, leave the Set as Main

Project checkbox selected, and click Finish.

5. To add the BPEL Module as a JBI module to the Composite Application project, right-

click the new Composite Application and choose Add JBI Module.

The Select Project dialog box opens.

6. Select the HelloWorld project you created earlier and click Add Project JAR Files.

The Select Project dialog box closes and the HelloWorld.jar file is added to the JBI Modules

node of the HelloWorldApplication Composite Application

Building and Deploying the Composite Application Project

Building a project compiles the BPEL source file and packages the BPEL file and web service

artifacts, including WSDL and XSD files, into a JAR archive. Deploying the project compiles

the files in the Composite Application project, packages the compiled BPEL and related web

service artifacts (including WSDL and XSD files) into an archive, and deploys them to the

Application Server.



37

To Build and Deploy the Composite Application Project

1. Right-click the Composite Application project's node, and choose Build.

When the build is complete the Output window reports Build Successful. If the Output window

is not visible, choose Window -> Output -> Output.

2. Right-click the Composite Application project's node, and choose Deploy.3. Deployment has succeeded when you see a Build successful message in the GlassFish tab

of the Output window.

4. Open the Services window and expand Servers -> GlassFish V2 -> JBI -> Service

Assemblies to see your new deployed Service Assembly.

If you do not see the deployed project, right-click the Service Assemblies node and choose

Refresh.

Testing the Composite Application

You can test your Composite Application project by adding test cases, binding to the operation,

supplying input, and then using the tester.

Test the HelloWorldApplication Composite Application Project

1. In the Projects window, expand the HelloWorldApplication project node, right-click theTest node, and choose New Test Case.

The New Test Case wizard opens.

2. Accept the default test case name, TestCase1, and click Next.

3. From the Select the WSDL Document page, expand the HelloWorld - Proecss Files node,

select Synchronous.wsdl, and click Next.

4. From the Select the Operation to Test page, select the Operation1 and click Finish.



39

When the Overwrite Empty Output dialog box appears, click Yes to accept new output. The first

test run populates the Output.xml file displayed in the Source Editor.

The test compares the output to the contents of the output file. Because the first run of the test

has nothing to compare itself to, the first test fails. Subsequent test runs will compare their output

with the contents of Output.xml and should succeed.

8. Run the test again.

The test case is compared to the current output file and succeeds.

Date:

AIM:

To develop .Net Client To Acess A J2EE Web Service

PROCEDURE:

Create a Java Web Service (Java EE, JAX-WS)

1. Create a new Web Application

In the NetBeans IDE 7.0, choose File –> New Project. In the New Project Dialog select theWeb category, and choose Web Application from the projects list. Then, Click Next.

In the Name and Location page, set the location where you want to create the web application,

and provide a name for the project. Click Next.

In the Server and Settings page, leave the default settings (Java EE 5, Use GlassFish V3) and

Click Finish.



48

This creates the initial web application and opens the project for editing.

2. Create the Web Service

Add a new web service to the project. Right click the project node and choose

New –> Web Service.

* Notice that the location of the Web Service option in the menu may change from this imageand your IDE.

In the New Web Service dialog, provide the Web Service Name, and the Package. The name of

the service will affect the final URL For Calling The Service, and the package name will be the

namespace of the service contract. Click Finish.



49

The Web Service now appears in the project tree.

To implement the service, double click the service node in the project tree (in the figure above –

CalculatorService). This will open the Web Service in Design mode, that lets you graphically

design your service.

Change to Source View by clicking on the Source button in the upper toolbar, and this will open

CalculatorService.Java file for editing. Here is a sample implementation of the service.



50

Notice how Java Annotations are similar to .Net Attributes, especially how similar they are to

the Web Services attributes we know…

“CalculatorService.Java”

package org.bursteg.calculator;

import javax.jws.WebMethod;

import javax.jws.WebParam;


@WebService

public class CalculatorService

{

@WebMethod

public int Add(@WebParam(name="a") int a,

@WebParam(name="b") int b)

{

return a + b;

}

}

Deploy the web service to the web application server. From the NetBeans IDE this is done by

right clicking the project node, and choosing Undeploy and Deploy.



51

After the web application has been deployed, just to make sure the web service works as

expected, you can right click the web service node, and choose Test Web Service.

This will open the browser and navigate to a test page with the url of the service

(http://localhost:8080/Calculator/CalculatorServiceService?Tester suffix.)



52

Call the Java Web Service from a .Net Client

In Visual Studio 2010, Create A New Console Application.

This creates a new solution with a single Console Application project in it.

Right click the project node and choose Add Service Reference.

In the Add Service Reference Dialog, paste the address of the service metadata endpoint

(http://localhost:8080/Calculator/CalculatorServiceService?wsdl ), and click Go. The dialog will

get the service metadata and understand the service contract.



53

Provide a namespace for the service reference, and click OK.

This will generate the client side proxy that lets you consume the service easily, and the required

configuration settings into the configuration file.

To call the service using the generated client side proxy, open Program.cs and use the following

code:

static void Main(string[] args)

{

CalculatorService.CalculatorServiceClient proxy = new

CalculatorService.CalculatorServiceClient();

int result = proxy.Add(2, 3);

Console.WriteLine("Calculator Service returned: " + result.ToString());

}



54

Run the program and see that the web service is being called and the result is correct.

Ex.No: JAVA WEB SERVICE AND INVOKE IT FROM ASP.NET

Date: APPLICATION

AIM:

To create Java web service and invoke it from ASP.Net application

PROCEDURE:

Create a Java Web Service:

There are a few steps involved in developing a web service using it. These steps can be

summarized as follows:

Create a web application project.

Add web service to the project.

Add operations to the web service.

Implementing the web methodes.

Deploy and test the web service.

Step 1. Create a web application project

In Netbeans IDE 7.0,Go To File->New Project. The New Project wizard opens.

Select the web from categories options and web application from project section and then press

the next button.

(i.e.,Java Web->Web Application)

Figure One: Create New Project Step 1



56

On the next screen mention the project name, select the project location. We can also mention

the server name in which we want to deploy our web application as well we can change thedefault context path.

Here we mention the project name JSimpCalcWebService and keep the context path same as

project name. We use GlassFish V2 application server for deployment.

Figure Two: Create New Project Step 2

Now, click the finish button.

Step 2. Add web service to the project



57

Right click on the project name in the Projects explorer window.

Figure Three: Web Service Menu Option

From the context menu options select the Web Service menu. A web service dialog opens.

Figure Four: Add New Web Service

Mention the web service name and the package name as mentioned in the image below, and thenclick the finish button.

In our example the web service name is JSimpCalcWebService and the package name is calc.ws.

Step 3. Add operations to the web service



58

After we add web service to our application, now it's time to add web service operation or

WebMethod. We can do it in two possible ways one is through design mode and another isthrough source mode. In our example we use design mode for creating skeleton of WebMethod

in easiest way.

Figure Five: Add Operation To Web Service

As we can see from highlighted section in the figure five we can add web service operations by

clicking Add Operation button. It opens a Add Operation dialog box. Please refer to figure six.

Figure Six: Add Parameters To Web Operation

In the Add Operation dialog we must mention name (which is actually a WebMethod name).

We can also enter parameter names and their types (these parameter are known as WebParam).

In the figure six we mention the WebMethod name as addition whose return type is

java.lang.String and it takes two parameters (parameter1. and parameter2) of type double.



59

Similarly we create other operations as well like subtraction, multiplication, division, power,

maximum, minimum.

Step 4: Implementing the web methodes

Once we finish step three, a basic structure of our web service should be ready. Then we switch

from design mode to source mode as shown in figure seven to do rest of the implementation.

Figure Seven: Write The Code For The Web Service

The code should look like as follows:

Collapse | Copy Code

package calc.ws;

import javax.jws.WebMethod;

import javax.jws.WebParam;


import calc.util.NumberFormater;

/**

* @author Bikash Shaw

*/

@WebService()

public class JSimpCalcWebService {

/**


*/

@WebMethod(operationName = "addition")

public String addition(@WebParam(name = "parameter1")

double parameter1, @WebParam(name = "parameter2")



60

double parameter2) {

//TODO write your implementation code here:

return NumberFormater.format((parameter1 + parameter2),0,6);

}

/**

@WebMethod(operationName = "subtraction")

public String subtraction(@WebParam(name = "parameter1")




return NumberFormater.format((parameter1 - parameter2),0,6);

}

/**

public String multiplication(@WebParam(name = "parameter1")




return NumberFormater.format((parameter1 * parameter2),0,6);

}

/**

@WebMethod(operationName = "division")

public String division(@WebParam(name = "parameter1")




61



return NumberFormater.format((parameter1 / parameter2),0,6);

}

/**


*/

@WebMethod(operationName = "power")

public String power(@WebParam(name = "parameter1")




return NumberFormater.format(Math.pow(parameter1, parameter2),0,6);

}

/**

* Web service operation*/

@WebMethod(operationName = "maximum")

public String maximum(@WebParam(name = "parameter1")




return NumberFormater.format(Math.max(parameter1, parameter2),0,6);

}

/**


*/

@WebMethod(operationName = "minimum")

public String minimum(@WebParam(name = "parameter1")



62




return NumberFormater.format(Math.min(parameter1, parameter2),0,6);

}

}

Source One: Java JSimpCalcWebService.java Web Service Source Code

Here we use NumberFormater.format(double number, int minFractionDigits,

int maxFractionDigits) method to format the double value to java.lang.String up to six decimalpoint. Refer to the source two.

Collapse | Copy Code

package calc.util;

import java.text.NumberFormat;

/**



63

public class NumberFormater {

public static String format(double number, int minFractionDigits,

int maxFractionDigits) {

NumberFormat format = NumberFormat.getInstance();

format.setMaximumFractionDigits(maxFractionDigits);

format.setMinimumFractionDigits(minFractionDigits);

return format.format(number);

}

}

Source Two: NumberFormater.java Source Code

Step 5. Deploy and test the web service

Now our web service is ready deployment and test. With Netbeans 6 it can achieved very with

few steps. First make sure that the GlassFish server is running. To start the server we need toperform the following steps.

Go to Services explorer window.

Expand the Servers node.

Right click on the server name (in our case its GlassFish V2). A context menu pops up.

Figure Eight: Start GlassFish V2 Application Server

Now, as our server is running it's time to deploy the application and test the web service that we

have developed. Netbeans does the deployment for us with few mouse clicks, mentioned as

follows:

Go to Projects explorer window.



64

Expand the Web Services node.

Right click on the web services name (in our case its JSimpCalcWebService). A context menu

pops up.

Click the Test Web Service menu.

Figure Nine: Test Web Service

The above mentioned steps deploy the application and lunch the default browser in which theweb service can be tested via SOAP request and response. Please refer to the figure ten for

sample output. We can also view the WSDL (Web Services Description Language) file by

clicking on the hyperlink.



65

Figure Ten: Test Web Service

Alternatively we can test the web service and view its WSDL document through our GlassFish

application server’s admin consol as shown in figure eleven.

Figure Eleven: Test Web Service via Admin Consol

Once we click on the View WSDL link we can view a XML file for describing our web service.

The WSDL file should look like the figure twelve.



66

Figure Twelve: WSDL File

The URL shown at the address bar will require invoking the web service. We shall demonstrate

its usage during creating of our web application using ASP.net.

Create ASP.net Web Site Using C#:

Now, our web service is ready to get invoked from non Java based development platform. In this

article we develop a sample ASP.net based client. Using Visual Studio 2008 it can be achieved infew steps, which can be summarized as follows:

Create ASP.net web site.

Add web reference.

Write code to invoke web service.

Test web service client application.

Step 1. Create ASP.net web site

Start Visual Studio 2008; go to the New →Web Site… which is available under File menu.



67

Figure Thirteen: New Web Site Window

Select ASP.net Web Site.

Select the folder in which we want to create the web site. In our case it’sJSimpCalcWebServiceWebSite

Select the language Visual C# and click OK button.

Step 2. Add web reference

Now we need to mention the WSDL file in our web site. To add the web service reference we

must perform the following steps:

Go to Solution Explorer window.

Right click on the project name (in our case its JSimpCalcWebServiceWebSite). A context menu

pops up.

Click the Add Web Reference menu. The Add Web Reference dialog opens.



68

Figure Fourteen: Add Web Reference Context Menu

Copy and paste the WSDL URL from our web brower’s address bar (refer to figure twelve) toAdd Web Reference dialog’s address bar and press go button (refer to figure fifteen).

Figure Fifteen: Add Web Reference Dialog

We can see all the methods names of our web service. Give a name to the web reference (in this

example its JSimpCalcWebService) and click the Add Reference button.

Step 3. Write code to invoke web service

Using C# we can very easily invoke the web service with few lines of code:

We first design an ASP.net page. The default fie name is Default.aspx (the source is available inzip file).



69

Induce the web reference in to our code (i.e. Default.aspx.cs). For example:

using JSimpCalcWebServiceService;

Next, create the object of the web reference.

JSimpCalcWebServiceService.JSimpCalcWebServiceService proxy = new

JSimpCalcWebServiceService.JSimpCalcWebServiceService();

Now, we can access the WebMethod like any other method call. For example:

proxy.addition(10,20);
