The information on the roadmap and future software development efforts are intended to outline general product direction and should not be relied on in making a purchasing decision.

Outline

• Introduction• Patterns for team application development• A pattern for Java component development

Situation

• Non-trivial application• Code version management system in place• Several developers• Multiple development configurations• Heterogeneous code base• Deployment to Dev/Test/Prod servers

Solution Components

• PP Protocols• PP Components• Java/.NET/Perl/Python/Dynamic Java/… PP components• SQL DDL and DML code• HTML, JavaScript, CSS• Custom application (Java EE, .NET,…)

Development Model

Key Issue

Synchronisation of XMLDB with an SCM repository

Patterns for AEP Application Development

• XMLDB only• In-situ package• Sibling packages• Package container

Version Management of Protocols in XMLDB

• XMLDB as primary component/protocol storage• On demand export/import

File SystemXMLDB

XMLDB Only

• Benefits– Simple– Can work without direct access to the PP server necessary

• Drawbacks– Works only with simple projects: PP components + protocols– Limited configuration management– No packaging

In-Situ Package

• mktree.pl• Straightforward for non-Java containing packages

PP_ROOT/apps/mycompany/mypackage Package directory

In-Situ Package

• Pros– Everything in one place– Standard package setup

• Cons– Access to server– Configuration management– Doesn’t scale for multiple packages– Doesn’t work for default Java component setup

In-Situ Package – Problems with Java Packages

• Suboptimal documented approach– mktree.pl– Eclipse setup with linked src/build dirs

PP_ROOT/apps/mycompany/mypackage Package directory

Eclipse workspace ?

In-Situ Package

• Set Eclipse workspace to PP_ROOT/apps/mycompany• New Java project in Eclipse, but use lang/java/src and

lang/java/build• DIY mktree.pl

PP_ROOT/apps/mycompany/mypackage Package directory

Sibling Packages

Problem statement• Do not want to provide customer with source code or

unit/regression testsSolution• Split package into production and

test/development packages

Sibling Packages

• Production package– Ships to customers– Components, protocols– Images, other resources– Build binaries

• Test/Development package– Regression tests and baseline files– Source code– Build scripts

mycompany/myproductmycompany/myproductdev

Sibling Packages – ChemReg

Package Container

Development outside of PP_ROOT

WorkspacePackage directory

Package installation

Package Container

• Pros– Most flexible– Can manage one or many packages– Proper configuration management– Can work with a remote server

• Cons– Requires some work to set up (meta-packaging)– Synchronisation with the server

Package Container – Folder Setup

Package Container – Build/Deployment Automation

Tasks• Standard tasks

– File operations (copy, delete,…)– Filters– Exec (pkgutil, regress, net)– Java (YUI Compressor)

• Database deployment– Third party SQL*Plus wrapper incanto.sourceforge.net

• Custom task to execute PP protocols• Source code management integration

Development of Java Components

1. Create package (mktree.pl)2. Create missing folders3. Create Eclipse project4. Develop Java class(es) implementing

com.scitegic.pilot.Component5. D&D Java (on Server)6. Configure Java (on Server) and add new parameters7. Save the new component8. Export the new component9. Install the package

Example Component Set – Integration with Columbus

• SOAP Method with WSDL Support component can call most methods: createProject, createDataset, getImageInfo etc.

• For image transfer Columbus uses SOAP MTOM (Message Transfer Optimization Mechanism) – not supported by AEP

Patterns For Custom Components

• Develop and deploy custom Java component under 5 minutes

Demo

DRY—Don’t Repeat Yourself

• Automation– Generate Java (on Server) component with the right GUID

(unique) – avoid pain of saving and exporting

• Metaprogramming– Write Code That Writes Code Components

• Possible validation of Java-PP component parameters

• Different approaches for team development• The power of plain text and XML• AEP-based development can be further automated and

improved
