As you (correctly) point out, the term "global" in a struts-config.xml file is currently only global within the scope of a module. In 1.1, modules are (essentially) totally independent of each other. Designing some sort of mechanism where modules could "inherit from" or "subclass" each other is likely to be a popular topic on STRUTS-DEV when we start laying out the roadmap for Struts 1.2. That way, you could put parent resources of various types in a parent module, and then specialize as desired. > 2) Forwarding between mdoules is awakward.

If you want to do it programmatically, use RequestUtils.selectModule() instead.

RequestUtils contains an amazing number of handly utility methods for all sorts of things like this, so the Struts Javadocs can really be your friend :-). > Sanjay Craig --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
