Development of WebDynpro Java with NWDS 7.1 for WebAS 7.0 possible?

[JK]

we have different J2EE Servers on different SAP Releases / Patch Levels (7.0 and 7.1)

can we use newest development studio 7.1 SP5 and develop webdynpros that are running with

old web as releases? or at least old patch levels?

any experience or recommendations on this?

No, the NWDS must not be newer than the server runtime. Otherwise the NWDS will generate code against new APIs that are not existing in the older runtime.

Thats a good point!! I tried developing a process and then deploying it onto NW 7.0 and it was a failure.

What about the other way round? Can I deploy DCs (e.g. Web Dynpro) developed in NWDS 7.0 or 6.40 on AS Java 7.1?

[Former Member]

Yes.

Are different service releases a problem, too? For example, currently I am developing in NWDS 7.1 SR5 for an AS Java 7.1 SR3. So far, it seems to work, but I am not sure if some bugs that I encountered are to blame on the version difference.

Different SPs in the same release are ok. Which bugs did you encounter?

Thank you for the fast response!

The bugs that I mentioned were various small bugs, but mostly in the NWDS. Right now I can't remember

any specific ones which could possibly have something to do with the version difference.

Different but related question: All my Web Dynpro projects contain warnings about divergent versions of

some DCs. Here is the result of "Check Project Archive Versions":

Apparently we imported SCs with SP number 6 into our NWDI tracks. What do you recommend me to do?

Ignore the warnings? Or look for SP5 versions of the affected components and import them into the track?

Hi Joreg,

I think that if you are developing something in NWDS 7.1 that was supported by NWDS 7.0 then it should definitely work on NW 7.0. But if you try to run somehing that is a new addon in NWDS 7.1 then it would be an issue.

Like if you ant to develop a process using Process Composer and deploy it on NW 7.0, then it would be a problem.

Hope this helps!!

Cheers,

Arafat
