WebAS J2EE Version

[Former Member]

hi all,

Could anyone tell me what version of J2EE is our NetWeaver 2004 and 2004s WebAS Java Stack based on?

pl. don't mistake me. I'm not looking for JVM on which WebAS runs on.

I just wanted to know what version of Struts and EJBs are supported in WebAS 04 and 04s.

Thanks

Arun.

Hi Arun,

NetWeaver 2004 and 2004s cover J2EE 1.3 specification. That will make EJB 2.0

However there is Java EE 5 Edition of SAP NetWeaver Application Server - the first to cover the Java EE 5

(Java EE 5 according to the "old versioning" would be J2EE 1.5.) That version has EJB 3.1 support.

Please <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/index?rid=/library/uuid/da699d27-0b01-0010-99b0-f11458f31ef2">check it out</a> for more info

Struts, at least up to my knowledge is not part of the J2EE specification, but is a framework from apache built on top of J2EE. It makes usage of servlets and JSPs.

As far as I know Struts versions higher than 1.3 require version 2.3 of the servlet specification. That servlet version is part of J2EE 1.3, so you should be able to launch it on the Netweaver 2004 and Netweaver 2004s servers.

Can you please explain on this point?

Hi Arun,

Struts is not a specification, but an open source framework provided by the apache foundation. That framework must be run on top of J2EE server.

The latest released Struts versions are 1.3.x. They are making use of servlets 2.3, JSP 1.2 and JVM 1.4. That is the minimum requirement from the server. Servlet 2.3, JSP 1.2 are part of J2EE 1.3 that the servers are covering. In addition the Netweaver servers can be launched with JVM 1.4 so the minimum requirements for running Struts 1.3.x are met.

You can check the Struts page for the server requirements:

<a href="http://struts.apache.org/announce.html">Struts doc</a>. You can double check as well in their forums to be sure.

There is Struts 2.0 but it is still under development. Perhaps the released version of Struts 2.0 will require in the future more from the server that will not be possible with Netweaver 2004 and 2004s.

However since all existing J2EE specifications are already covered in the Java EE 5 Edition of SAP NetWeaver Application Server, that should not be an issue.
