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. I have no clue as to why and how. But I do see that this is a ClassFormatException so, I moved the application related code (not struts) onto another machine where I previously deployed my app. The app was fine on this box earlier.Now, I get the same ClassFormatError there too so, It has to do with the code I moved. The Java API says that it is "Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file. " So .class file is corrupt/malformed. But which? I am trying to force a recompile on classes by adding a space, etc. any ideas on what sould be done next if my attempt fails? here is the exception....
