[jboss-user] [EJB 3.0] - EJB3 RC9 Deserialization Errors

[ALRubinger]

A note:

If you've upgraded JBoss 4.0.4-GA to EJB3 using the patch installer,  the EJB3 libs in $JBOSS_HOME/client are not updated.

If you continue to use these libs when accessing EJB3s from an RC9 server, you'll get something similar to this on deserialization:

Root exception is java.io.InvalidClassException: org.jboss.ejb3.remoting.IsLocalInterceptor;
  |     local class incompatible: stream classdesc serialVersionUID = -3758782076801249473, local class serialVersionUID = 595045557897063404] 

...because the EJB3 Proxy doesn't declare a serialVersionUID, as noted in http://jira.jboss.com/jira/browse/EJBTHREE-402

So use the JARs in $JBOSS_HOME/server/{instanceName}/deploy/ejb3.deployer.

Hoping this will save someone out there some time.

S,
ALR
