CE: Using EJB-Model of a WebDynpro-DC in another WebDynpro-DC

[Former Member]

Hi experts,

In CE I have two WebDynpro-DCs. The first one defines an EJB-Model and publishes this in a public part. The second DC should use the model. In order to do so it uses the public part of the first DC. The public parts contains the following entities:

- the model iteself

- the component

- the folder containing the files ".wdmodelclass" and ".wdmodel"

- the Java-package containing the model-classes

Unfortunately I get several errors when building the second DC. The file ".log" delivers this error message:

Can anybody give me some hint please?

Solution is:

Add following dependencies in second DC, which uses the model defined in first DC (contained in FRAMEWORK 😞

- tc/cm/ejb/api

- tc/ejblib/api

Regards,

Christoph
