Can we run JPA , JAXWS in J2EE 1.4 compatible app server?

Nope - JPA and JAX-WS are introduced with Java EE 5.

Even though JPA can be used standalone, there is no integration for it (of course) possible in J2EE 1.4.

But why would you want to do that in the first place? If you need to enhance an existing J2EE 1.4 app with persistence and WS, you could use e.g. Hibernate (very similar to JPA actually) and JAX-RPC instead of JAX-WS. If you start a new project then simply go for Java EE 5 and you can use SAP NetWeaver Composition Environment for your purposes.

HTH!

Thanks for your reply.

I want to develop app and run on SAP NetWeaver 7.0, which is not J2EE1.4 competiable, what about then.

You're right, it's J2EE 1.3. Well, JAX-RPC is not part of that, however there's already good WS support in SAP NW 7.0. You can find more information on the relevant pages on help.sap.com.

Hibernate is a standalone persistence framework, so it can be used for any type of Java app, particularly in your case J2EE 1.3. There's a good article on how to use <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/bf0d57db-0c01-0010-6fa3-83503981eed4">Hibernate on SAP NetWeaver</a>.

HTH!
