I am getting a java.lang.ArrayStoreException whenever I attempt to run an update query using JPA 2.0 and Websphere. I am using the test utility, and I successfully update the correct rows and so forth, no transactions are rolled back, I just get that exception and my application doesn’t execute. How can I resolve this… I don’t know if the stack trace will you do you any good… But since this ia stack overflow I thought I would post it anywho…

Every time I look up the exception I get the advice that some types are being mismatched? But I don’t know that to be the case. Everything would seem fine… What Am I missing? Does anybody have any insight into why this exception occurs?
Without seeing any code I would have to say you’re mixing up your types.
