[jboss-dev-forums] [Design of JBossXB] - problem parsing sip.xml with JBossXB

Hi,

First, sorry for the long post :-)

We are currently porting our implementation of Sip Servlets (see http://www.mobicents.org/products_sip_servlets.html) on top of JBoss 5 (currently working on Tomcat and Jboss AS 4.2.3).

Our source code for the port is currently available from http://code.google.com/p/mobicents/source/browse/trunk/servers/sip-servlets/sip-servlets-jboss5 (svn browsing)

Most of the work is done and working but we encoutered a problem related to JBossXB unmarshalling. I just hope anyone can help out there.

A bit of background related to sip servlets. It kind of reuses the same semantics from the http servlet 2.5 spec to provide support for the SIP protocol in a friendly manner to developers used to http servlets development.

So instead of having a web.xml deployment descriptor, pure sip servlets applications have a sip.xml instead.

the sip.xml corresponding xsd can be found at http://www.jcp.org/xml/ns/sipservlet/sip-app_1_1.xsd

We modified the metadata-deployer-jboss-beans.xml to add the sip.xml metadata parsing stuff by adding the following to the SchemaResolverConfig bean

 <!-- SipMetaData -->

  sip-app_1_1.xsd
  org.jboss.metadata.sip.spec.Sip11MetaData


   sip-app
   org.jboss.metadata.sip.jboss.JBossSip11MetaData


The first entry is the one causing the problem. It is used when the sip.xml contains the xmlns stuff in it for xsd validation. The corresponding class can be found here :
http://code.google.com/p/mobicents/source/browse/trunk/servers/sip-servlets/sip-servlets-jboss5/src/main/java/org/jboss/metadata/sip/spec/Sip11MetaData.java

The second one is used when xmlns stuff is not present and works fine.

The problem is have is when I try to deploy the following descriptor http://code.google.com/p/mobicents/source/browse/trunk/servers/sip-servlets/sip-servlets-examples/call-blocking/src/main/sipapp/WEB-INF/sip.xml

The part that is commented, when uncommented, gives me the following error when I deploy the app :

the sip xsd import the web app 2.5 xsd through  <xs:import namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="web-app_2_5.xsd"/>
to import the javaee servletType to define sip servlet in the sip.xml descriptor so it seems the xsd validation should be ok with regard to servlet type.

It is strange that it fails on servlet-name saying that servlet-name is expected. 
Has anyone ever see this behavior or can help here ?
That would be greatly apprectiated.

Also I was wondering if the following was correct too ?
<sip-app xmlns="http://www.jcp.org/xml/ns/sipservlet" 
		xmlns:javaee="http://java.sun.com/xml/ns/javaee">

because when I try to parse it it gives me the following :

I think this is because it cannot find entry or class matching to do the unmarshalling but I don't know how to correct that neither...

Thanks in advance
