Hi
I am trying to get a resource froim the application packages. I use
this :
RWT.getResourceManager().getResource("ro/val/resource.txt")
this returns null
if I try to register the resource with
RWT.getResourceManager().register("ro/val/resource.txt")
I get exception :
Caused by: java.io.IOException: Resource to read not found:
ro/val/resource.txt
at
org.eclipse.rwt.internal.resources.ResourceUtil.openStream(R esourceUtil.java:228)
at
org.eclipse.rwt.internal.resources.ResourceUtil.readBinary(R esourceUtil.java:177)
at
org.eclipse.rwt.internal.resources.ResourceUtil.read(Resourc eUtil.java:46)
the resource.txt file is in the source path in the ro.val package
Thanks for any help,
Val

Val,
you need to set the ResourceManagers' context-classloader just before
you register the resource and reset it to its previous value afterwards.
If there is a class that resides in the same package as the resource to
load, its classloader would be a good candidate. Usually, any class that
resides in the same bundle should do (special cases left aside, they all
share the same classloader).
Typical code could look like this:
IResourceManager manager = ResourceManager.getInstance();
ClassLoader buffer = manager.getContextLoader();
manager.setContextLoader( <YourClass>.class.getClassLoader() );
try {
// register resource
} finally {
manager.setContextLoader( buffer );
}
