nor would the fact that we're using DB2

> A bit esoteric, but I defined a datasource in TomEE (using tomee.xml) and deployed my
app along with the datasource. I then wrote a quick throwaway app (as a test to prove out
an issue I was troubleshooting) that grabbed an org.apache.openejb.client.RemoteInitialContextFactory
and attempted to look the datasource up. When I ran this, I get the following:
> Exception in thread "main" java.lang.ClassCastException: org.apache.openejb.client.ThrowableArtifact
cannot be cast to java.lang.Error
> 	at org.apache.openejb.client.JNDIContext.lookup(
> 	at javax.naming.InitialContext.lookup(
> A bit of debugging through the source showed that the original error generated was this:
> JNDI_ERROR:java.lang.NoSuchMethodException: org.apache.openejb.resource.jdbc.managed.local.ManagedDataSource.getDriverClass().
> Of course, the NoSuchMethodException implements Throwable, which is implemented by Error.
Perhaps casting the return of getResult() to Throwable might be a better approach?  
> I can *try* to take a look at this if you want...just let me know.
