I think you need to check it first, because the error indicates jdk/jvm differences, here is how:
The first 4 bytes are a magic number, 0xCAFEBABe, to identify a valid class file then the next 2 bytes identify the class format version (major and minor). Possible major/minor value : major minor Java platform version 45 3 1.0 45 3 1.1 46 0 1.2 47 0 1.3 48 0 1.4 49 0 1.5 50 0 1.6 http://www.rgagnon.com/javadetails/java-0544.html Chris -----Original Message----- From: stlecho [mailto:[email protected]] Sent: Wednesday, 19 May 2010 9:50 PM To: [email protected] Subject: Re: ClassFormatError when using Enhancement Builder The Java version I'm using in Eclipse is JDK1.6 and this is the only one installed. I suppose that the Enhancement plugin uses the same one. I've been doing several times "Clean Project", but this does not solve the problem. Using the OpenJPA Enhancher Agent option works perfectly, so I suppose that the configuration and code annotations are correct. Do you have any further ideas ?
