java.lang.NoClassDefFoundError: while starting Integration Builder!

[Former Member]

Hello experts,

I was working on IR absolutely fine. The connection went off and I tried to log in to IB again. It gave me locking error when I was trying to edit any object. So the BASIS guy stopped the XI server and tried to make it up again.

After that when I am trying to open Integration builder, its giving me the following error:

"Application error occurred during request processing.

Details: java.lang.NoClassDefFoundError: com.sap.aii.ibrep.server.transport.impl.service.InternalRepTransportServiceImpl (initialization failure)

Exception id: [000D604D0DA7005D00000019001FC08E0004424566F0368A]"

Neither me nor my BASIS guy are having any idea why this error is comming all of a sudden when everything was working absolutely fine.

Can anyone please help me in resolving this issue as this is very critical?

Thanks in advance.

Regards,

Yash

Hi Yash !

Try to restart your workstation and also try to delete all the cached objects from the Java Web Start that were download the last time you started the Integration Repository. Also the BASIS guy should check in the SAP Management Console of the XI installation, that all services are running.

Hi Matias,

We tried all possible ways like restarting the workstation and the server. Infact only after we stoped the server and tried to put it up, this problem started coming. It was working fine perviously. We are trying all possible ways to reslove it but till now no major success. It is really hampering my development schedule.

I will ask my BASIS guy to check the management console. Even I tried to see what was the error in the XI administrator login and i found that many of the services (under Admistration - Application) are either in status "Stopped" or "Implicit_Stopped" and when we try to start them, they dont get started!! One of the application among them is also tc_slmslmapp! How can that be started?

Will thsi problem impact on all the developments i have done till now?

Also the detail error trace which i get when starting IB is:

"Message

java.lang.NoClassDefFoundError: com.sap.aii.ibrep.server.transport.impl.service.InternalRepTransportServiceImpl (initialization failure)

Hi !

Based on your mails I see that the problems seems to be in the server. Just in case, try to access from another workstation.

About your developments, if there is no database problem, they should be fine.

Remember that starting netweaver takes some minutes (25-100 minutes states in the manual), depending on your hardware resources, maybe you need to wait more.

Can you access to the http://yourhost:50xxx address ?

Matias.

Hi Matias,

thanks for your inputs. the problem is resolved now. There was some problem in ABAP connector. The BASIS guy resolved that and restarted all the services manually and it started working.

Thanks once again.
