Hi,

Its Problem in ur .metadata folder. try this

First Close your NWDS.

1) Go to NWDS installation directory, take a backup of your projects from the workspace and delete the .metadata folder from the workspace.

2) Then open the NWDS, a new .metadata folder will be created and now you can try opening the NWDS it will open without error

3)Sometimes when your metadata of the NWDS is corrupted then your NWDS will not function properly.

Hi Suresh,

I have done what you have said and now its working fine.

But,

As i installed NWDS again i need to get back my Project(DC) in the NWDS.

How can this be done?

I had tried several options and i was fortunate enough to get back my Project but I am unable to Check-Out Source in the NWDS,thus i am struck here as i cannot further proceed to go on with my Work.

Please help me out to resolve this issue.

Thanks and regards,

Chandrashekar.

Hi,

Try running it from the command line with the "-clean" option. Maybe it'll help. Also make sure your JAVA_HOME path is set correctly.

hai chandrasekhar,

The problem is may be your using the same source for reinstallation.when it says error in log file the reuired files in metadata are missing.so take a source wch is working and go for reinstallation.

Thanks n regards
