EX NO-6aSIMPLE SERVLETDATE:

AIM:

To write a html and servlet to demonstrate invoking a servlet from html.

ALGORITHM:

Create one root directory

Now create another folder web-inf in the root directory, this web-inf folder contains web.xml file

Create classes folder with in web-inf folder

Compile our servlet program which is in src folder, so we will get one .class file right, just copy this .class file into classes folder in web-inf folder

By the way, we are going to run our servlet by using Tomcat server. So we must set the class path for Tomcat related jar file, servlet-api.jar

You can find this jar file in your Tomcat 1.0\lib.

Open the command prompt and type C:Program Files\Apache Software foundation\tomcat 7.0\web-apps\root\web inf\classes.

Compile the file using the path C:\Program Files\Apache Software Foundation\Tomcat 7.0\lib\servlet-api.jar

Run the file in IE
