[jboss-dev-forums] [Design of JBoss ESB] - WS Endpoints :: WSDL rendered dynamically

[andretemple]

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.
