[jboss-dev-forums] [Design of JBoss Serialization] - Interceptor medasata issue

[tterm]

Hello,

I'm not sure if this is the right forum for my question. If not sorry and please point me to the right one.

I get allways a class cast exception if I put some values into the metadate from the invocation object in the invoke method of an interceptor. It works fine with JBoss until version 4.0.3SP1. But with later versions I run allways in this issue. 

In a client side interceptor I do the following:


  | SimpleMetaData metaData = invocation.getMetaData();
  | 
  | metaData.addMetaData(InterceptorConstants.ARM_TAG,
  |   InterceptorConstants.ARM_CORR_KEY, corr.getBytes());
  | 
  | 

corr.getBytes(); is a simple byte array


If I do an EJB request I get allways this exception:

I tried to debug this thing but I couldn't get it why it occurs. 

I appreciate any help and thanks in advance. If more information is required I'll post it.
