Migration from JSF to GWT 1.5

As far as I had to fix small project I had a task to fix JSF application. I need:
1.Add sorting
2.Fix flow
What I have is ant with many libs and JSF version 1.1.2
Problems:
1.JSF doesn't support table sorting.So do use this I need to use extensions such as Tomahawk or Trinidad as far as I worked with Tomahawk I used it.Last version in maven repositary is Tomahawk 1.1.5 so I used it. JSF 1.1.2 is not compatible with it so I replaced it with myfaces 1.1.5.After that many operations in applications didn't worked I had a lot of time to fix

In the same time I started to write the same application but on GWT. The 1 problem was that JSF Bean has UI, SQL, POJO in 1 Bean.

Time estimations will be discuss later

Migration from JBoss 4.0 to Tomcat 6.0(JNDI context)

JNDI resources types:
1.Global - myDS
2.Local java:/comp/env/myDS

By default JBOSS has global JNDI context
Tomcat has local JNDI context

To export property:

JAVA_OPTS="$JAVA_OPTS -DpropertyDS=java:/comp/env/myDS"

Where propertyDS - name of system property that will be used in your application
