This may not be the what you're having problems with, but the only time I've seen this was when I was deploying via FTP and forgot to set my scripts to use binary mode.

Re: java.lang.ClassFormatError out of the Blue
Jason Thanks for the response. The absence of scripts in binary mode clearly justifies the exception. Iam trying to run it in my own Test Environment. And moreover, the .class files are in the repository. Even if I export them, they seem to get exported in corrupted format. Iam trying to export .Java files, delete project from workspace/repository, and import all the java files again. Hoping that would work.

Are you saying that the .class files are in a source control repository? If they are stored in CVS, make sure you check them out with the binary flag set.

Hi hemant I got that same error and i discovered IDE (metrowerks) was creating that problem when it was preparing jar file. I generated the class files using IDE and jarred them using command line then the problem was solved. my advice is to create jar file by command line and try your problem will be solved. hope this helps umamaheswar -Original Message- From: hemant [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 09, 2002 12:55 PM To: Tomcat Users List; struts Subject: java.lang.ClassFormatError out of the Blue I Use Tomcat 4.0.2 and Struts 1.0.2 with VA 3.5.3 Everything was perfect until, one inauspicious moment in the afternoon when I suddenly got this exception from nowhere.
