Yesterday, I sent out this email:
Stumped on a complicated question:
I am getting the following error:
java.lang.ClassNotFoundException:
org.ofbiz.service.engine.StandardJavaEngine
On this line 81 of
org.ofbiz.service.engine.GenericEngineFactory.getGenericEngine:
Class c = loader.loadClass(className);
I am running ofbiz as a standalone app, similiar to java ofbiz.jar -pos
I have solved the problem and the solution was fairly simple. I was
prepared to do a reflection call to addURL on the ClassLoader, but the the
solution turned out to be even simpler than that.
When Ofbiz instantiated my container, I simply grabbed the class loader it
used to start me up and then passed it to the Ofbiz connection layer like
this:
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if(loader instanceof URLClassLoader)
{
URLClassLoader urlLoader = (URLClassLoader)loader;
connection.setClassLoader (urlLoader);
}
In the connection layer, I have this code:
void resetClassLoader()
{
if(this.loader == null)
return;
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if(loader != this.loader)
Thread.currentThread().setContextClassLoader(this.loader);
}
I then simply call resetClassLoader() every time before I call an Ofbiz
service.
Works a charm.
