NWDS encountered error when launching workspace

[Former Member]

When I launched my NWDS, the studio automatically closed after encountered error.

Here is the error messages I got form the workspace /metadata/ .log:

Thanks for advise.

Hi Kent

Such error occurs when number of opened files in studio is too big. To fix this it's enough to delete file '..\workspace\.metadata\.plugins\org.eclipse.ui.workbench\workbench.xml' from workspace of your studio.

Sergei,

You are right. That is the reason why my Studio had the errors.

Thanks.

Hi,

Can you try opening with a new workspace? To change the workspace right click on the SAP NWDS shortcut and go to Properties-Shortcut tab->Target and give

"C:\Program Files\SAP\JDT\eclipse\SapIde.exe" -vm "C:\j2sdk1.4.2_08\bin\javaw.exe" -data "<new workSpace>". Here <new workSpace> means your new workspace folder. Make sure that this folder exists before changing the workspace.

Regards,

Satyajit.

hi Kent,

If NWDS is installed in the PC with some userid and then you are trying to open the NWDS with another user ID which doesn't have the admin rights on the system this kind of error occurs.

HI, Gopi.

I am using the j2eadm user account (that was created during the installation). It is because the Administrator user account was disappeared when I reinstalled my Workplace. (I might accidentally select to delete domain user account).

If I recreate the Administrator user account, helpfully this can solve the probelm.

Hi Kent,

try removing the .metadata folder from the path C:\Documents and Settings\UrUser\Documents\SAP\workspace and relauncing the NWDS.

Bhavana,

I removed the .metadata folder and successful relaunch the NWDS.

It works.

But I am researching why this happen from times to times for my studio.

Maybe the reasons are like all SDN fellows mentioned in this post.

Thanks.

Kent
