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.

did you see the ant install.xml file that comes with the EJB3RC9 distribution and the INSTALL directions? It should patch everything for you. If this ant script didn't work, please let me know.

thanks

Apologies; just double-checked the installer. I must have done this previously and checked the wrong installation of JBoss for updates.

Disregard.

Related, but it is $JBOSS_HOME/client/jboss-ejb3x.jar that is not updated.
