Any solution for the Getting SAXParseException?

[sattanathan 0]

Hi, I'm using deployment descriptor for ejb2.0 on websphere application server. I needs to use timer service(non persistent property) in the deployment descriptor. But while running the build to create a deployable jar, i'm getting below exception. "org.xml.sax.SAXParseException: Element type "timer" must be declared." I'm having the doubt that non persistent timer property is available from ejb 3.1, but i'm using ejb 2.0 DTD in my descriptor code. <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/...ejb-jar_2_0.dtd"> Can anyone tell me whether i'm correct? if not let me know the solution...
