ObjectInputStream.resolveClass & ClassNotFoundException

[igeorg]

Hi,

I've hit the ObjectInputStream.resolveClass feature while trying to access a serializable context variable from within an action.

For a description of the problem, have a look here:
http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4340158

One of the suggested workarounds is to subclass ObjectInputStream, override resolveClass() and use the context class loader for class resolution.
JBoss implements the suggested workaround in:
org.jboss.invocation.MarshalledValueInputStream

Would it make sense to use this in SerializableToByteArrayConverter?

Thanks
John

The page you refer mentions JDK 1.3. Are you using that? jBPM won't compile against it.

Hi Alex,

No, I'm using 1.4.2_05

I've checked the source code of ObjectInputStream for both 1.4.2 & 1.5 and they both make a magic call to a native lastUserDefinedClassloader() call to resolve classes.

I've changed SerializableToByteArrayConverter to use a class like JBoss'
org.jboss.invocation.MarshalledValueInputStream
instead of ObjectInputStream and the ClassNotFoundException was gone
