I get the following null-pointer-exception message when trying to edit a *.umr document in Eclipse.

I think I installed the trial version of MyEclipse plugin properly, but this piece seems not to work. I would appreciate any suggestions for a remedy.

Is this a UMR file you created previously? If you open up the navigator view, and you should see a file with the same name and extension .umr~, if you rename that to .umr and try and open it, did that work?

If not, please paste the results of MyEclipse > About > Configuration Summary here for us.

[jgtanner43]

I don’t know what the protocol is for respoinding: post or private mesage. So I’m copying the configuration you asked for here.

Also, the file is new and 0 bytes in length.

Jim,
The UMR file, even if it is empty, should still be a few KB big, if it is infact of size 0, then the file is likely corrupt and that is why it won’t open.

Did you try my suggestion about the UMR~ file? Did it have a different size?

[jgtanner43]

There was no umr~ file.

The error occurs when I try and create a new file with a umr extension. Eclipse/MyEclipse goes through an initialization sequence, but comes up with the error I indecated earlier.

I have a straight Eclipse 3.1 install has far as I know. Any other features and plugins have been installed outside of the Eclipse 3.1 install directory/location.

[Riyad Kalla]

Instead of creating a file and manually typing the umr extension try using File > New > Other > MyEclipse > UML > UMR, and create the file that way, did that work?

If not, open your log file (<workspace dir>\.metadata\.log) and paste the exceptions near the end here for me to see.

Also, do you have any EMF or GEF plugins in your <eclipse dir>\plugins directory?

[jgtanner43]

File > New > Other > MyEclipse > UML > UMR worked!

I do not have any EMF or GEF plugins.

Thanks for your help and patience with a new Eclipse and MyEclipse user.

Jim

Ahh, the reason for this is that if you don’t use a file type, the file-associated wizard isn’t run; normally you don’t notice this with xml, jsp, html, etc. files because it’s OK if they are blank, but the UMR file is actually a ZIP of 3 separate metadata files, so it’s important to use the new file wizard. Glad it’s working.
