It sure looks like the system (Service libraries) rather than application classloader is being used, despite your code that clearly sets the contextClassLoader to the container's.
Have you checked that poaCurrent doesn't change the context classloader and the classloader is really what you expect when you call toObject? david jencks On 2001.11.21 13:04:25 -0500 Francisco Reverbel wrote: > Hi, > > I have a classloader problem in the IIOP container invoker code and would > really appreciate some helpful hints...
