ConnectorHandler doesn`t work in Grails

[Darran]

The ConnectorHandler can`t dynamically load a Connector class when the Connector class is part of the Grails app.

The line Class<?> clazz = Class.forName(className);

causes a ClassNotfoundException.

If this is changed to Class<?> clazz = Thread.currentThread().getContextClassLoader().loadClass(className);

it will work, see ​http://www.nabble.com/ClassNotFoundException-with-Class.forName-td18194398.html

for details.

Hmm, that's bad. I somwhat assumed that this will fail sooner or later. Is this a known bug to Grails?

I guess, I have to write a CallUti which traverses standard class loader and then context class loader.

Please check whether other interfaces fail loading too. I guess so. As soon as you can confirm this, I can create a branch with a patch, let you double-check it and then merge back to trunk.

FYI I found this issue when creating a Connector from within a Grails app. I`ve not tested creating a Connector in Java then dropping the jar into the grails app.

Replying to Darran:

I have already realized that. What I was refering it, is that I'd like you to check our other interfaces from within your app. They will probably fail too. I just want to make sure.

[Michael Osipov]

I'd like you to test you case with other interfaces as well. Without your participation a real test and verification is not possible.

[Darran]

I will try to do this asap when I get a moment.

Have you been able to reproduce this bug with the other interfaces?
