Description jmborer 2011-03-22 12:22:21 UTC 
I have a new issue with the GUI builder of NB 7.0rc1: somehow it seems not to be able to locate/load resources. I use Maven projects. 

I have a Project A that has a dependency on project B. In the constructor of my panel, I use a class from project B  that loads a resource (LSZH_sectors.xml). I've checked the jar and the resource is actually contained in project B's Jar. So why is the GUI builder complaining it is not able to find it? Is there an issue with the classpath that the GUI builder uses?

Comment 1 Tomas Pavek 2011-03-22 14:39:27 UTC 
Is LSZH_sectors.xml in the same JAR and folder as AirspaceFactory.class?
How does AirspaceFactory look for the resource?
Comment 2 jmborer 2011-03-22 14:57:23 UTC 
I found out my problem: former code used ClassLoader.getSystemResourceAsStream(inputFile) to load the resource, which seems not be working anymore. Using the Class classloader resolves the problem but I had to fix all the paths to resources to be relative to that new classloader.
