Error in deploying Axis2 Web Service

[Mohandeep Singh]

Hi Guys,

Web Server
RHEL5
Apache Tomcat 6.0.18
Web Service running on Axis2 1.4, being called from a PHP SOAP client [on another RHEL5 Server].

While connecting to Oracle 10g (on another RHEL5 server], it throws following error:

"[ERROR] AxisEngine - oracle/dms/instrument/ExecutionContextForJDBC org.apache.axis2.AxisFault: oracle/dms/instrument/ExecutionContextForJDBC".

stack trace: java.lang.reflect.InvocationTargetException
    ...
    ...
    ...
Caused by: java.lang.NoClassDefFoundError:

Few other things:
Connectivity from Web Server to Oracle is confirmed
JDBC drivers are available in lib folder [and I couldn't found any duplicate]
The same setup [web service] is running perfectly on another Linux server

Any help will be highly appreciated, its quite tight situation for me.

Thanks & Regards,
Deep
