Hi,

if i did not mention any default handler,i am getting following error..

Hello,
First of all - I'm a complete newbie to jBoss, first time ever trying to get a test-enviroment up and running. I have the jboss-7.1.1-Final application server running on a Linux box. And as a first project just want to create a simple webservice using javax.ws but I can't get the application to deploy, I'm using ant to build a simple .war file and then copying into {JBOSS_HOME}\standalone\deployments. However I get the exception:
23:28:20,665 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/webservice]] (MSC service thread 1-1) Servlet /webservice threw load() exception: java.lang.InstantiationException

Hi Mike,
I'll comment later on the classpath / client topic.

I did a bit of additional investigation on this topic today. Basically, Apache CXF is able to reply to WS-MEX requests sent to "/mex". The problem is with properly configuring the STS endpoint on JBoss AS.
You need to have the JBoss Web layer deal with HTTP messages to the /mex subpath, for instance by having a web.xml descriptor as follows (please note the wildcard in the url pattern):
<web-app ...>
<servlet>
<servlet-name>TestSecurityTokenService</servlet-name>
<servlet-class>org.jboss.test.ws.jaxws.samples.wsse.policy.trust.SampleSTS</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestSecurityTokenService</servlet-name>
<url-pattern>/SecurityTokenService/*</url-pattern>
</servlet-mapping>
</web-app>
Besides that, I unfortunately found a bug in the jbossws-cxf SubjectCreatingInterceptor which basically block any WS-MEX call, see https://issues.jboss.org/browse/JBWS-3543 https://issues.jboss.org/browse/JBWS-3543 . It's fixed on jbossws-cxf trunk and will be in next release.
This said, there're many complaints on the net regarding Metro default behaviour wrt WS-MetadataExchange and STS endpoints; btw Glen Mazza also created a WSIT / Metro improvement ticket at http://java.net/jira/browse/WSIT-1586 http://java.net/jira/browse/WSIT-1586 long time ago (for a better configurability of Metro), but that's not been worked yet.

Hi,
Where can I see the possible configuration supported to create web services?
Like eclipse, jdk, JBossWS, JBoss AS, etc...
I am asking because my company has a system in JBoss AS 4.2.2 with jdk 1.6.0_07 and I need to create a web service. But when I try to create the web service using the eclipse wizard, I get the message:

I am using the JBossWS from the JBoss AS, at JBossWS Preferences I just appointed to JBoss AS folder...
Any idea?
Thanks!
