README for directory \project_resources\ext-resources The ext-resources directory is the extension directory in VisualAge for Java. Projects that are tagged as extension projects (meaning they are loaded using the ExtClassLoader) will have their resources directories here. For example the resources for an extension project called MVMProj will be put in: ide\project_resources\ext-resources\MVMProj As in the JDK1.2 jars can be placed in extension directories and will be picked up by the environment. Code like Class.forName("mypackage.FooBar"); will look for a class named mypackage.FooBar in a jar in the ext-resources directory.
