Migrating from Web AS 6.20  

Use

If you plan to upgrade to SAP Web AS 6.40, you may want to migrate your JBuilder-based development to SAP NetWeaver Developer Studio. For J2SE development, the SAP NetWeaver Developer Studio provides a wizard to help in the conversion. However, for J2EE development, the considerable differences in project structure and deployment (and deployment descriptors) means that there is no automatic migration available. You will normally have to manually separate your application into components and adjust the folder structures before you can import it into the SAP NetWeaver Developer Studio.

Procedure

Importing J2SE Projects

       1.      Choose File → Import → jpx Project

       2.      Follow the instructions in the wizard and choose Finish.

       3.      If necessary, make manual changes so that your project can be built without errors.

Importing J2EE Projects

       1.      Create a new J2EE (EJB, Web or Enterprise) project.

       2.      Copy the source files (including the folder structure that corresponds to the package structure) into the source folder (ejbModule) of the project.

       3.      In the Package Explorer, choose Refresh. This will make the source files visible in SAP NetWeaver Developer Studio.

       4.      Apply any manual changes necessary so that your project can be built without errors.

       5.      In the J2EE Explorer check that the SAP NetWeaver Developer Studio has recognized your enterprise beans, servlets, JSPs and so on.

If some enterprise beans have not been recognized (this will happen if they do not comply to certain naming conventions), choose Assemble EJB from the context menu of the node Bean Registry. Then you can manually combine the corresponding source files (Bean class, Home and Remote Interfaces) into an enterprise bean. See Assembling EJBs from Existing Classes.

Result

The corresponding project and its components are displayed and can be edited as if they were created in the SAP NetWeaver Developer Studio.
