Like I said in the sticky, deploying Spring .war file/application is what Spring is all about - see their basic instructions. JBoss (Tomcat) in this case only serves as a web container.
What JBoss/Spring is about, is the integration with EJB3 or any AOP injection capable module.
but its still using 1.2.5 version of spring
Not true. There is not so new release that supports Spring 2.0.
So I need to know how to start spring application context from a war file.
See Spring instructions.
There must be Spring specific ServletContextListener defined in web.xml.
Please are you able to supply a simple war file example?
Any working .war should do.
JBoss (Tomcat) is a normal web container. ;-)
