[appengine-java] Re: Exception while deploying JSP Tag Lib Files
Klaus - I had the same problem, but there is a way to fix it. Take a look at the link suggested by Rajeev: http://groups.google.com/group/google-appengine-java/browse_thread/thread/175e70cc0c93ded9 About 75% of the way deep into the thread you'll start to find some solutions. For me, there were two things that I had to do (these are detailed in that thread): 1. Copy tools.jar into the AppEngine lib/shared directory. 2. Modify appcfg.cmd so it fully-qualifies the reference to java.exe in the JDK/bin directory. I switched from Eclipse to IntelliJ IDEA a month or two ago, and upgraded to the newest App Engine SDK. However #1 was still required on my machine. Don't give up hope, you're almost there! - Jim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Exception while deploying JSP Tag Lib Files
I forgot to point out that the deployment works fine for *regular* JSP file. Everything works fine if you *don't* have JSP Tag files, so if you don't make use of the tag world (resp. if you delet the file world.tagx) in the above example. It' not a general failure of the deployment process, and I successfully had deployed JSP files before.

[appengine-java] Re: Exception while deploying JSP Tag Lib Files
Hey Klaus, I think you may be running into the issue mentioned here: http://groups.google.com/group/google-appengine-java/browse_thread/thread/175e70cc0c93ded9 This is a pretty bad hack, but can you try copying the tools.jar file from your JDK's directory (the one which your project in Eclipse is using) over to your App Engine SDK's lib/shared directory and see if that helps?
