NoClassDefFoundError - af.service.trace

Hi,

I wrote java client that call ejb on xi server.

When calling the method i got exception:

<i>java.lang.NoClassDefFoundError: com/sap/aii/af/service/trace/Trace

at com.sap.aii.messaging.mo.Message.<clinit>(Message.java:54) at java.lang.Class.forName0(Native Method)

at java.lang.Class.forName(Class.java:219)

at com.sap.engine.services.rmi_p4.MarshalInputStream.resol

ve Class(MarshalInputStream.java:66)

at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1513)</i>

I didn't found a file with that name on the server.

I will appreciate your help,

Roni.
