NWDS 7.1 and NW AS 7.0

[Former Member]

We develop portal application based on Web Dynpro framework. We use NetWeaver Developer Studio 7.0.11 as developer tool and NetWeaver AppServer 7.0 as target for deployment.

We have found that NWDS 7.0.1 based on Eclipse 2.0. This version of Eclipse is not convenient enough to develop effectively. Moreover, NWDS plugins have numerous bugs in visual editor. Well, we tried NWDS 7.1. Wonderful! This version is good! We want to use this version of NWDS.

Question: can we develop Web Dynpro components and deploy portal application on NW 7.0 using NWDS 7.1? What troubleshootings can we get?

You have to use a NW 7.0 IDE when developing for NW 7.0 server.

Hi Alexey Dmitriev,

Welcome to SDN!

Generally,we use lower or equal versions of NetWeaver Developer Studio as that of NetWeaver Application Server.

The problem you may encounter is

jar files and plugins of IDE may not be supported by NW WEBAS

The real problem is that with a NW 7.1 IDE there is code generated that does not run on a server with lower runtime.

It seems strange enough. I developed j2ee applications for WebSphere using Eclipse and no problems in version conflict for code generation have tried. There was code developed for lower WebSphere version but that code have been deployed in higher WebSphere without problems. Why is not possible lower version compatibility for SAP Web AppServer? Why does not NWDS generate code for lower versions of NW? What matter?

The problem is that the NWDS 7.1 generates Java code that requires NW libraries 7.1.

I have read about ppl trying to use the NWDS plugin from 7.0 in a newer version of Eclips, but no reports of 100% success.

From a Jave perspective there is a big difference between 7.0 and 7.1, 7.0 uses Java 1.4 and 7.1 uses Java 5.
