Fabian, This looks almost certainly like you are compiling with two different versions of the JDK. Spit out the version from the OS and compare that to the version set for Eclipse and Ant.

I have a webapp with JSP's using some classes from WEB-INF/classes in a declaration block (<%!%>), running in tomcat 6 on jdk1.6.0_14. The problem is such, if I compile the classes in WEB-INF/classes using eclipse Galileo everything runs fine. But if I compile those same classes using ANT, jsp comilation in tomcat fails with the following stack trace: org.eclipse.jdt.internal.compiler.classfmt.ClassFormatException at org.eclipse.jdt.internal.compiler.classfmt.ClassFileReader.<init>(ClassFileReader.java:342) at org.apache.jasper.compiler.JDTCompiler$1.findType(JDTCompiler.java:206) at org.apache.jasper.compiler.JDTCompiler$1.findType(JDTCompiler.java:178) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.askForType(LookupEnvironment.java:122) at org.eclipse.jdt.internal.compiler.lookup.PackageBinding.getTypeOrPackage(PackageBinding.java:178) at org.eclipse.jdt.internal.compiler.lookup.Scope.getPackage(Scope.java:2101) at org.eclipse.jdt.internal.compiler.ast.QualifiedTypeReference.getTypeBinding(QualifiedTypeReference.java:69) at org.eclipse.jdt.internal.compiler.ast.TypeReference.resolveType(TypeReference.java:134) at org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding.resolveTypeFor(SourceTypeBinding.java:1273) at org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding.fields(SourceTypeBinding.java:604) at org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding.faultInTypesForFieldsAndMethods(SourceTypeBinding.java:582) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.faultInTypes(CompilationUnitScope.java:431) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:616) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:392) at org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:429) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:334) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:312) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:299) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:589) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:619) This happens as well under tomcat 5.5. Changing the ANT build to use the same JDT compiler as eclipse did not change the problem. Using javap I checked both compiled versions of the classes and they do have the same major version. Any hint towards what might be the problem here is greatly appreciated. Thanks a lot, fabian -- ____________________________________________ u n i t b c o n s u l t i n g Brunnenstr. 156 10115 Berlin Tel: +49 [0]30 44 31 92 00 Fax: +49 [0]30 44 31 92 29 Mail: off...@unitb-consulting.de Web: http://www.unitb-consulting.de Geschäftsführer: Nico Adam, Thomas Timm Registergericht: AG Berlin-Charlottenburg - HRB 113607 Steuernummer: 37/249/21073 Ust-IdNr.: DE814984825 Diese E-Mail könnte vertrauliche und/oder rechtlich geschützte Informationen enthalten.
