Do you mean that you were putting the directory that contained the OpenJPA jars into the taskdev-time classpath? In Java prior to version 6, you must always enumerate jar files themselves; putting the dir that contains the jar files into the classpath doesn't get its contents into the classpath.
This is changing in Java 6 with the addition of a new property for listing dirs containing jars, but I'm not sure how that manifests itself in ant, or if you're using Java 6. Also, you will need the execution-time classpath to include your persistent types. As it turns out, you don't need the OpenJPA jars in the execution-time classpath; just in the taskdef-time one. The duplication won't hurt, but isn't strictly necessary.
