COM Wrapper CheckVer

You can run CheckVer to verify whether a previously generated COM object is compatible with another environment. Typically, a system administrator performs this task.

The XML files generated by GenCOM are the signatures of the objects generated against specific JD Edwards EnterpriseOne environments. These XML files can be used with CheckVer to verify that the wrappers on the COM server are compatible with these environments.

When you introduce a new JD Edwards EnterpriseOne environment, you run GenCOM against the new environment by using the /NoCompile option. You also use the iJDEScript that you used to generate the wrappers on the COM server to generate XML signature files for the objects in the new environment. Run CheckVer on the COM server with the newly generated XML files to verify that the new environment is compatible with wrappers on the COM server that was previously generated with a different environment. CheckVer updates the registry settings for the wrapper on the COM server according to the result of the compatibility test. If the new environment is incompatible, the COM client cannot create business objects with the new environment.
