Migrating Web Dynpro Java to 7.5 - Java heap error on using ARFC2

[former_member929263]

Hi, all.

We are migrating some Web Dynpro Java projects from 7.3 to 7.5 version.

Everytime I start migrating some of the RFCs to ARFC2 and do binds, create methods etc, the Eclipse Framework (NWDS 7.5) also start showing some errors, related with heap memory etc.

The point is: the virtual machine I'm using it has enough memory space and drive space, as well (drive C has 15 GB free):

Does anyone have a clue what is going on?

Here are my eclipse.ini configs:

Thank you.

Hello Ana Carolina,

Which Support Pack and Patch Level of NWDS are you using? And are you connecting it to an NWDI system to deploy your WDJ project to an AS Java or Portal? If so, what is the Support Pack level of NWDI? It is important that NWDS and NWDI match each other in SP level, and then in general you should use the highest patch level of NWDS for that SP level. It's also a good idea for the SP level of NWDI to match with the NetWeaver SP level of your target Portal system, though I'm not sure this is as important as matching NWDS to NWDI (it's more important to match the SP level of the required SAP components in your NWDI development track to your Portal SP level).

Cheers,
Matt

Hi, Matt, thanks for your comment.

I'm using 7.5 SP 18. We don't use NWDI, deployment is straight to AS Java via .ear files.

Any other ideas?

Thank you.

Hi Ana

Check this SCN thread with same error message and check the SAP note as mentioned in the thread

Thanks, SS.

I'm waiting the infra team to instal it and take a look on these logs.

Regards,

Ana.
