I had to reinstall myeclipse/eclipse combo after having some horrible svn problems (turns out 1.3 can’t read 1.4 .svn files and cygwin and myeclipse were using different versions). After upgrading subeclipse I tried my handy dandy ant script which creates my applet and found it’s no longer signing the jars. This happens AFTER it unjars and javac’s a jar. The script hasn’t changed either, it just went from working before the rebuild to not working. The specific error is :
BUILD FAILED
C:\myeclipse\eclipse\Workspace\shared\build\build.xml:450: Execute failed: java.io.IOException: Cannot run program “jarsigner.exe”: CreateProcess error=2, The system cannot find the file specified
(This comes from the console window)

My signjar task hasn’t changed. I did upgrade my my java plugin to 1.6.0.
MyEclipse preferences shows Ant – Runtime – ClassPath:Global Entries pointing to my new tools.jar in the jdk1.6.0\lib directory. (I assume this is what makes javac work).
Under Java – Installed JRE’s I have checked my new jre1.6.0

I had to reinstall some key plugins so I’m thinking this might be causing the error. I’m running the script through Cygwin now which works fine, but I’d rather be using my IDE.

The only thing that looked like it might be vaguely relevant from the myeclipse log file is this section:

Any help would be greatly appreciated!

Stan,
You probably need to be sure to update your environment’s PATH variable to include your new JDK’s /bin dir, that is where jarsigner lives, and likely why you can’t find it. Just try and launch it from the command line and see if that works, if it doesn’t, you need to adjust the path.

That was indeed the problem. Thanks much for the timely, insightful response.
