StreamCorruptedException from Java Client calling Stateless EJBs
William Poitras
following exception. This works in one of my environments, but the same
software doesn't in another. I can't find the differences between the
two environments. Anybody have any ideas where to look? I've made sure
both machines are running the same versions
Java:
java version "1.3.1_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_03-b03)
Java HotSpot(TM) Client VM (build 1.3.1_03-b03, mixed mode)

Hello William,
I would suggest comparing the CLASSPATH variables of the two environments. Try
to figure out if there is something in the CLASSPATH of the machine that's throwing
the exception that could be blocking the actual API that you wish to use. For
example, I have seen this error occur when trying to use java.sql.Blob instead
of using WebLogic's OracleBlob in weblogic.jar. I'm not sure if you are working
with BLOBs at all, but I'm sure that this could be a CLASSPATH issue. If the CLASSPATH's
are the same, then please provide further information about what your code is
actually doing so that we may further investigate the problem.
Also, see the following link for more possible causes of the problem:

My Java client resolves the home from the clustered machines (which has
the beans built with clustered homes) and calls the EJB and expects an
object implimenting the Collection interface in return.
The Stateless session bean queries a Sybase database, puts the result
set into an ArrayList of value objects. The value object class is
externalizable and only uses primitive types or object versions of those
primitive types. The EJB returns the ArrayList.
The classpath for both environments is the same for both the WLS servers
and the Java client.
