Is the class you're missing. I don't recognise that - what software is it?

EMC Documentum.

Make sure that class is in one of the jars you mentioned and if so, that they really *are* in the classpath (of the server if necessary in addition to your webapp)

> I have the dfc.jar and the dfcbase.jar included in the classpath

they shouldn't be in your classpath, they should be deployed as part of webapp (in WEB-INF/lib)

you can check the contents of a jar using the jar command

jav tvf <jar file name>

I have them in the WEB-INF/lib folder also. I got the same exception and so had put them in the classpath.
Is there any other reason for this exception other than not including the jar files?

I had also checked the dbor.properties file and all the business objects are registered.

Please post the listing of the jars

jar tf <thejar>

> Is there any other reason for this exception other than not including the jar files?

It means the classloader cannot find the specified class. Meaning the jar file is not available to it.
Perhaps also checj the class name and package that they are spelt correctly

eg. is it IPF not IPf

> Please post the listing of the jars
> jar tf <thejar>

Thats already been suggested, stop repeatedly copying other experts comments :)

I had checked for the spellings and they all match.

IPfDocument is a custom interface class which extends IDfBusinessObject provided by the DFC 5.2.5. It is present in dfc.jar which I mentioned earlier. There are a hierarchy of objects provided by documentum and so I am guessing the problem lies in the import of those jars.

Do you happen to specifically know what I am missing other than dfc.jar and dfcbase.jar?

You also need to check

jar tf <thewar>

for those jars

> Do you happen to specifically know what I am missing other than dfc.jar and dfcbase.jar?

u are missing the class mentioned, if it is in that jar then the jar is not being seen by the classloader.
