Metro : JAX WS catalogue

One of the problems with using Netbeans to generate web services using Glassfish / Metro is that when you want to create a new Web service client, you are asked to select the web service which is normally on your local machine.

This means that the web service has an address like http://localhost:8080 and it then becomes a problem when you deploy to other environments.

One way around this is to use a catalog to resolve the addresses at run time. The file is called jax-ws-catalog.xml and it's placed in the META-INF directory.

It looks like e.g.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system">
rewritePrefix="http://some url:some port/"/>
rewritePrefix="http://some url:some port/" />

This searches for any URL that starts with "http://localhost:8080/" and replaces this with "http://some url:some port/" e.g.



http://some url:some port/webserver/WebService

The ant build files in Netbeans use the -catalog option to point to a file called catalog.xml in the project root directory. You can apply the same principles to this file to resolve addresses at compile time.
