Hi All, Thanks for all the help, but the true solution I found was to replace the tools.jar in tomcat5 with the tools.jar file from jdk1.6. Now I'm able to get Struts2 up and running.
And they have a thread in sun's website related to this: http://forum.java.sun.com/thread.jspa?threadID=5121172 thanks, Jack -----Original Message----- From: Jack Yu [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 08, 2007 9:46 AM To: 'Struts Users Mailing List' Cc: 'Jae Lim' Subject: RE: problem with Struts 2 setup -class file has wrong version 49.0, should be 48.0 Ok, I have did all the steps below, and still can't fix this version problem with Java. 1) Delete the "Catalina" folder under tomcat5/work/ 2) Restart tomcat 3) Make sure javac and java are both 1.6 from the command line, and in the tomcat configuration, the jvm path is: C:\Program Files\Java\jdk1.6.0_01\jre\bin\server\jvm.dll 4) Go to http://localhost:8080/struts2-blank-2.0.6/ And get this error: ============================================================================ javax.servlet.ServletException: Unable to compile class for JSP Generated servlet error: C:\Tomcat5\work\Catalina\localhost\struts2-blank-2.0.6\org\apache\jsp\exampl e\HelloWorld_jsp.java:7: cannot access java.lang.Object Generated servlet error: bad class file: C:\Program Files\Java\jdk1.6.0_01\jre\lib\rt.jar(java/lang/Object.class) class file has wrong version 49.0, should be 48.0 ============================================================================ Version 48.0 is Java 1.4, version 49.0 is Java 1.5, but I only have version Java 1.6(Version 50.0) on my computer right now. Another question I have raised is that I downloaded and installed Java SDK, do I need to download Java EE separately?
