Description eden CLA 2010-11-24 09:13:43 EST 
Build Identifier: 20100917-0705, Version: Helios Service Release 1

When trying to connect to the CVS server, the following error message appears:

Could not connect to ... CVS communication error: 
org.eclipse.team.internal.ccvs.ssh2.cvsssh2serverconnection$ssh2ioexception: DH KeyPairGenerator not available

- Trying the exact same hostname/repository path etc. from other computers works well.  
- Deleting the workspace hasn't solved the problem.

Many thanks, eden


Reproducible: Always

Steps to Reproduce:
1. Install a fresh Eclipse, start it and create a new Project from CVS
2. Add repository location, including login, repository path, hostname etc.
3. Click "Use an existing module"

Is there a stack trace available in your Error Log view? What connection method did you pick when creating the repo location?

The error log (Window-->Show View-->Error log) seems empty.

> What connection method did you pick when creating the repo location?

extssh.  It has always worked on this machine (and continues to work on others).

Thank you Tomasz for looking into this!

What JDK are you using? This error may indicate that you're missing Sun's JCE extensions. You must have them installed in order for the cryptix classes to work.

Thanks Tomasz.

The latest () is installed.  I've just re-installed it to see if it solves the problem.  It did not.  Sorry.

Take a look at this thread: http://www.eclipse.org/forums/index.php?t=msg&goto=31960&. Please paste in the result of "java -version".

Dear Tomasz,

Many thanks for that.  Remarkably, it worked!

What's remarkable is that I've seen this post before, and reinstalled twice the most recent Java SDK.  It has not solved the problem.  This round I've taken the time to uninstall (with Revo Uninstaller, namely uprooting every trace in the Registry/file system) every single Java installation--past versions, JRE, SDKs, the whole lot--and then re-install just the SDK.

The wonders of modern software...  In any case, thank you!
