HI I am previously using ant to build a jsf1.2 and jbossseam2.2 application to deploy in JBoss EAP6.4, which was successfully build and deployed in the server but when I am changing the build to use maven, I am getting the below error

I have followed all the configuration changes suggested for the above error, i.e. changes the jboss/as/weld/mocule.xml and jboss/weld/core/main/module.xml and added slot1.2 in javax.faces.api and also the jboss-deploymentStructure is already having the chenges to exclude jsf main slot and added dependency of slot1.2. But still getting the same error if I am building the application using maven could any one help me out of this. I already spent two eeeks on this.
