jboss, myfaces, tomahawk - HELP badly needed....

Dear All,

I'm using Jboss 4.0.3 SP1 and myfaces 1.1.1, I'm having a project
consisting of an EJB application and a web application. Both projects are
in one ear. I'm having an entity bean whose method is returning an instace
of the class TreeNodeBase which can be found in tomahawk.jar, This method
is called by an backing bean... But - I'm having really hard problems with
tomahawk.jar, if I put it inside the WEB-INF/lib of the web project, and
make it visible to the EJB project by an entry in manifest.mf I get:

****

Usually this exception means that a jar is located in two places in the
classpath but this time I'm completely sure it's not the case.

If I put tomahawk.jar outside the web project that is:

in the ear's main directory or
in the jboss'es lib,
in the tomcat's lib

I get the following message:

****


javax.servlet.ServletException: /admin/console.jsp(20,0) The absolute uri:
http://myfaces.apache.org/extensions cannot be resolved in either web.xml
or the jar files deployed with this application

Please help me, I would be grateful for any advice, I spend working on it
like 30 hours, once it has even worked but after deleting the tmp and work
directories it stopped, that makes me believe that it is possible to make
it work somehow...

Thanks in andvance for any help

not sure if this is the same problem I had, but try setting UseJBossWebLoader to true in jboss-4.x.x\server\XXX\deploy\jbossweb-tomcat50.sar\jboss-service.xml

These two docs may help as well:

Someone on another forum had the same problem and here is the solution:

extract all tld's from the myfaces-all.jar,
copy the myfaces-all.jar to the lib of the server,

and that's it !

I guess it is not the nicest solution but it is working..

The new application servers detect tld files in jars automatically. I don't know about jboss but tomcat-5 or jetty-5 doesn't need you to define each tld in web.xml.
