[jira] Commented: (OPENJPA-1860) How do I get OpenJPA to use my custom classloader to load Entity classes?

    [ https://issues.apache.org/jira/browse/OPENJPA-1860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926817#action_12926817 ] 

Hugh commented on OPENJPA-1860:
-------------------------------

Thank you very much.

Although it was a bit difficult to convince the custom ClassLoader to use the external resource after I rewrite it. And then to build the jar in netbeans with the right sort of Class-Path entries, your suggestion worked. ( I wanted to use the -jar argument )

I spent a lot of time looking for this solution and I'm really grateful. I'll post your idea on a few of the other forums I asked this question on.

Thorbjørn Ravn Andersen (slf4j author) was asking this same question on stackoverflow and told me he never found a solution.

> I have written a custom classloader and I can't work out how to get OpenJPA to use it to load my entity classes.
> I've followed instructions I found to set Thread.currentThread().setContextClassLoader() at startup before loading any EntityManager and it seems to load the OpenJPA classes and a lot of others, but not the class I'm interested in.
> Is this the right approach?
> If so, where have I gone wrong? (http://openjpa.208410.n2.nabble.com/Dynamic-Table-value-td5645906.html)
> If not, how should this be done?
> Is there some sort of guide to accomplishing this that someone could point me to?
> Thanks.
