Subject RE: [jira] Commented: (OPENJPA-8) java.util.MissingResourceException: system is missing product derivations
Date Fri, 11 Aug 2006 14:22:44 GMT
I am using this with SE5:

<fileset dir="D:/Personal/projects/MyMoney/openjpa-0.9.0/lib">
    <include name="**/*.jar"/>
</fileset>

Which doesn't work.  Unpacking the jars and pointing the classpath at
that directory does the trick.

java.util.MissingResourceException: system is missing product
derivations


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.

Hope this helps,

-Patrick
