[rules-users] Problems with GWT WebProject and Drools5.0!

[ben780]

Just a follow up to my last message.

I actually did figure out how to get pass this error.  The
knowledgeBuilderFactory.newKnowledgeBuilder() uses the java property
"user.home" to get the user directory.  So in order to get around using your
docs and setting folder you need to set the property to something else:

System.setProperty("user.home",
"C:\\workspace\\MyWebApp\\war\\WEB-INF\\classes");

This will allow you to place your conf file in your WEB-INF folder.

>From here on it seems like the rule engine works (I got it to fire and to
print out results).  But I do get another secuirty error that I havn't been
able to figure out yet (this one is a bit more obscure).

My best guess is that I need to modify something in the ResourceBuilder
configuration.
