Bean problem: No interface classes found

[Former Member]

Hi ;

I try to create a adapter . according to tutorial "How To Create Modules for the J2EE Adapter Engine"

https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/f013e82c-e56e-2910-c3ae-c602a67b918e&overrid...

Although I did all steps in it , I copied sda files and extract them then I imported them to the project but I get this error in Netweaver Studio "Bean problem: No interface classes found" while creating ejb file.

the document says you must close and reopen project when you come accross this error but it doesnt work?

Is there any one solve this error?

ps: I use NWDS 7.0.19 , I copied aii_af_lib.sda, aii_af_svc.sda and aii_af_cpa_svc.sda files from PI 7.01

as mentioned in the pdf

After setting up the EJB environment, you receive the error message: Bean problem: No
interface classes found. This occurs because there is no Java source available for the
EJB interface classes.
u2022 Choose the Package Explorer view in the Developer Studio.
u2022 Choose your project, and in the context menu, choose Close Project.
u2022 Choose Open Project again.
u2022 Finally, switch back to the J2EE Explorer view.

the error disappers but if you close the nwds and again open it appers again.

there is no problem .You can ignore this error and proceed with the next steps to develop an adapter module

Hi Tuncer!

Did you download and "import" these JAR files into your NWDS Build Path - classpath variables:

com.sap.aii.af.lib.mod.jar <bin>/ext/com.sap.aii.af.lib/lib

sap.com_tclogging_javaimpl.jar <bin>/system

com.sap.aii.af.svc_api.jar <bin>/services/com.sap.aii.af.svc/lib

com.sap.aii.af.cpa.svc_api.jar <bin>/services/com.sap.aii.af.cpa.svc/lib

com.sap.aii.af.ms.ifc_api.jar <bin>/interfaces/com.sap.aii.af.ms.ifc/lib

<bin> stands for: /usr/sap/<SID>/<instance-id>/j2ee/cluster/bin in a PI 7.1 system.

Windows -> Preferences -> Build Path -> Classpath Variables -> New ...

Choose a name of your choice and then select the JAR files mentioned above.

This should resolve your problem.

Can you still try to create the EAR file? I think this shouldn't be a problem for you if you ignore this error.
