    WS Endpoints :: WSDL rendered dynamically

    a a Newbie

      Hi all,

      I've checkout the jbossesb-4.4.GACP from SVN and took a look in publish_as_webservice sample.

      After some tests I realized that when I import some xsd into main xsd something goes wrong. Exploring the generated artifacts from JBossAS I saw that imported xsd was not copied into deployed services (tmp directory) and here is the problem.

      So I got the source code from JBoss4ESBDeployer and did a few changes.

      Below is the snippets from xsd and source code.

      I think it's a good idea to include something like this in JBossESB new release, since we always have a complex xsd structure and could expose it as a service in the bus.

      What do you think?

      tks.
