Failed to create comet support class in JBoss 6.4 - jboss

Error: failed to create comet support class: class org.atmosphere.container.JSR356AsyncSupport, error: null
When I try to start JBoss with my application this error occurs; without my application the server starts fine. POM editor says atmosphere 2.42 is a dependency, which is the comet dependency I think.
How do I resolve comet dependency so JBoss is able to resolve it (STFW)?

The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory is not working from eclipse

I am trying to deploy a gradle web project using tomcat in eclipse and when I am trying to access the application it throws me an exception as follows:
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: [36] in the generated java file: [......plugins\org.eclipse.wst.server.core\tmp0\work\Catalina...\org\apache\jsp\error_jsp.java]
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
Stacktrace:
at org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:103)
The same application I am able to deploy manually in the tomcat server with out using eclipse then it is working perfectly.
Please provide me a solution.
While deploying the application into server using eclipse it is adding some dependencies which are conflicted to dependencies added using gradle, after removing the conflicted jars the solved the issue.
the generated war only have the jars which are configured in the gradle so that is working when we deploy it manually on the server.

after restarting the eclipse, i am getting the error:
Unable to create editor ID org.eclipse.jst.pagedesigner.PageDesignerEditor: An unexpected exception was thrown.
any ideas why, and how to solve it ?
UPDATE:
when i tried to select java server faces again from the project facets, i found that it says on the right:
Conflicts with the following facets:
Application Client module
Dynamic Web Module
EAR
EJB Module
JCA Module
Static Web Module
Utility Module
Web Fragment Module
i was having JSF and ICEFaces dependencies in my pom, and i was having their libraries too in the classpath, fixed the error by removing them, and adding JSF,icefaces capabilities to my project, everything works fine now.

jsf-console 3.x on JBoss 6.x possible?

I'm trying to move an application from JBoss 4.2.2 AS to 6.x AS. Right now I'm trying to get jbpm 3.x running on the AS I have this problem when trying to upload a .par file to the server:
13:41:51,713 ERROR [org.jbpm.db.GraphSession] (http-127.0.0.1-8888-1) java.lang.ClassCastException: org.jbpm.graph.def.Node_$$_javassist_92 cannot be cast to javassist.util.proxy.ProxyObject
Which then results in:
13:41:51,740 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/app].[ProcessUploadServlet]] (http-127.0.0.1-8888-1) Servlet.service() for servlet ProcessUploadServlet threw exception: org.jbpm.JbpmException: couldn't find process definition 'ProcessName'.
I've tried using both old and new versions of javassist which has no positive effect. Any ideas?
It seems you are using eclipse plugins and you have class loader problem between 2 plugins, make sure that you have only one class loader to load ProxyObject (Javassist)
