[Former Member]

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.

Hi Roni,

search the following path in your server to get the jar

j2eeclusterserver0appssap.comcom.sap.xi.services

Checkout the section 3.1 in this pdf link https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3bdc14e1-0901-0010-b5a9-a01...

to download libraries.

Regards,

Uma
