J2EE Tests with JLin 

J2EE tests are part of the DEFAULT variant. Usually, these tests are not selected. Although you can select and execute the tests in the normal way, we recommend using project validation to run J2EE tests (see below). If you choose to use project validation, all the relevant J2EE tests are executed (selection or deselection is not relevant) each time the project is built.

Tests check the consistency of the XML descriptors in the J2EE projects against the specifications (as far as is possible statically). Before any other tests are run, the schema validation is run. If this test fails for a descriptor, none of the other tests are run on the descriptor.

Project validation is usually active by default (and you cannot switch off validation for building archives). If you need to activate it, do as follows:

...

       1.      In the J2EE Explorer or the Package Explorer, right click the project.

       2.      Choose Properties.

       3.      Select Validate as part of the build.

In the Problem view, you can see the results of the JLin validation tests. There is a separate type, JLin Validation Problem, in the filter of this view.
