hi folks... java doc from sun has fol explanation of ClassFormatError - 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 jvm is able to find y'r class file but i guess some version problem is there. this is what i obtained from sun java docs guide - This problem is caused by bytecode generated from old JDK 1.0.2 or 1.1 compilers, which generate bytecode that does not conform to the Java VM Specification. Since the verifiers in recent J2SE releases are much stricter about bad class format, ClassFormatError is thrown by the VM when these bad class files are loaded. that means u have compiled y'r classes with older version of jdk and trying to run them with newer version of jdk. check out this possibility. hope this helps regards nitin ___________________________________________________________________________ To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff SERVLET-INTEREST".
