Java Forum / General / March 2007Error with java programs after installing apache tomcat
Hello everybody I am using Win XP , JDK 6 . The environment variables are set as : PATH :C:\ProgramFiles\Java\jdk1.6.0\bin and CLASSPATH : . (Dot). I have recently installed tomcat 6 - I used the Windows Service installer - apache.tomcat.6.0.10.exe . I have not added any environment variables after installing tomcat, as I tested http://localhost:8080 and I got the tomcat welcome page. Now I face problem whenever I want to run any java programs, I get error message : Exception in thread "main" java.lang.UnsupportedClassVersionError: Tutorial05 (Unsupported major.minor version 50.0) Before installing tomcat I did not have any problems running my java programs. Please help me.... Thank you so much . > I am using Win XP , JDK 6 . The environment variables are set as : > PATH > > C:\ProgramFiles\Java\jdk1.6.0\bin and CLASSPATH : . (Dot). > Exception in thread "main" java.lang.UnsupportedClassVersionError: > Tutorial05 (Unsupported major.minor version 50.0) The problem is that Tomcat isn't being run in the 1.6 JVM, but you are asking it to load classfiles compiled with a 1.6 JDK. I don't know anything much about running Tomcat as a service, but I'd guess that the %Path% you've set is wrong, or that it's not being picked by the "user" who the service runs as (remember that Windows has two %Path%s), or that there are some missing startup options to the Tomcat service. Maybe it's because: C:\ProgramFiles\Java\jdk1.6.0\bin which looks wrong, shouldn't it be: C:\ProgramFiles\Java\jdk1.6.0\jre\bin ? -- chris > Maybe it's because: > C:\ProgramFiles\Java\jdk1.6.0\bin > which looks wrong, shouldn't it be: > C:\ProgramFiles\Java\jdk1.6.0\jre\bin > ? There are Java executables in the JDK bin also. -- Lew Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
