Assembling J2EE 1.4-Compliant Enterprise Applications  

Use

In this document you can find the differences between the wizards for creating J2EE 1.4-compliant and Java EE 5-compliant enterprise applications in the Developer Studio. They are both created using the Enterprise Application projects wizard but with different project facets for each version.

Procedure

Creating an EAR

...

       1.      In the context menu of the Project Explorer, choose New → J2EE → Enterprise Application Project. Choose Next.

       2.      Enter the name of the EAR application project and select SAP Web J2EE 1.4 Project in the Configurations field. In the Target Runtime field, select SAPLibraries. This automatically sets the necessary libraries for building the project as specified in the Configurations field. Choose Next.

       3.      Define the project facets. You can save the currently selected facets; these are the default facets for the SAP Web J2EE 1.4 Project which you chose in the Configurations field. The default facets are:

○       EAR with version 1.4

○       SAP Specific EAR Module with version 1.4

Optionally, you can: Create SAP JMS resources descriptor or add SAP Application Library Container, SAP Data Source and SAP Data Source Aliases Provider Module facets.

You can change the project facets later at any time by choosing Properties → Project Facets in the context menu of the project.

       4.      Choose Finish.

Editing Deployment Descriptors

When you create an Enterprise Application project, the Developer Studio automatically creates both application.xml and application-engine.xml. You can use the multipage editor for editing the deployment descriptors to configure your enterprise applications.
