Re: unknown source error

[Martin Redington]

Hi Abhijat,

I think you can see the 3rd party stuff fine.

you aren't getting the line numbers on the stack traces because you don't have the source code, and the line number have been stripped from the 3rd party binaries.

The problem you're having doesn't look like a missing class issue.

cheers,
m.

Hi Martin,

I have the third party libraries in the docBase/WEB-INF/lib of my web
application. I believe that is the place from where tomcat will look for
any jar files. Is there any other place where the third party libraries
should be?

thanks

Hi Abhijat,

I think the "Unknown source" messages are because you don't have the
source for the third-party libraries, and the line numbers can't be
determined from the class files.

A ClassCastException usually occurs because you are trying to cast an
object to an incompatible class (e.g. because the target class is not a

parent class to the object's class).

Hope this helps ...

cheers,
Martin

We intergrated a third party SOAP server with Tomcat. All it involved

was adding an entry in the web.xml file for SOAP servers servlet.The
SOAP server does publlish the service but when i invoke the service
from the client it does call the service but any code executed
corresponding to the third party software in the web service throws a

ClassCastException and there are Unknown Source messages.

It gives Unknown source for any classes corresponding to the third
party software. Is it a class loading problem? what am i doing wrong?

thanks
