Configuring Multiple Mapping Projects

Each session is associated with at least one mapping project (see "Configuring a Primary Mapping Project"). You can include additional TopLink mapping projects for a session.

Table 77-8 summarizes which sessions support additional mapping project configuration.

To add an additional mapping project to this session, click Add. For more information, see "Configuring a Primary Mapping Project".

To remove TopLink mapping projects, select the project file and click Remove.

Using Java

Using Java, you can register descriptors from more than one project with a session using the Session API that Table 77-9 lists. Descriptors should be registered before login, but independent sets of descriptors can be added after login.

Table 77-9 Session API for Registering Descriptors

Session Method	Description
addDescriptors(Project)	Add additional descriptor to the session in the form of a project.
addDescriptors(Vector)	Add a vector of individual descriptor files to the session in the form of a project.
addDescriptor(Descriptor)	Add individual descriptors to the session.
