Hallo, ich möchte prüfen welche Java Version gerade auf meinem Fedora Core 3 installiert ist. Also hab ich ich in der Konsole eingegeben: java -version Dann kam folgendes: This change was necessary because the rmiregistry, rmic and jar tools installed by previous versions of libgcj conflicted with symlinks installed by jpackage.org JVM packages. Exception in thread "main" java.lang.NoClassDefFoundError: version at gnu.gcj.runtime.FirstThread.run() (/usr/lib/libgcj.so.5.0.0) at _Jv_ThreadRun(java.lang.Thread) (/usr/lib/libgcj.so.5.0.0) at _Jv_RunMain(java.lang.Class, byte const, int, byte const, boolean) (/usr/lib/libgcj.so.5.0.0) at __libc_start_main (/lib/tls/libc-2.3.3.so) [clemenshartmann@localhost ~]$ java -version libgcj-java-placeholder.sh This script is a placeholder for the /usr/bin/java master link required by jpackage.org conventions. libgcj's rmiregistry, rmic and jar tools are now slave symlinks to these masters, and are managed by the alternatives(8) system. This change was necessary because the rmiregistry, rmic and jar tools installed by previous versions of libgcj conflicted with symlinks installed by jpackage.org JVM packages. gij (GNU libgcj) version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3) Welche Java version habe ich jetzt?
