From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: The priority of /usr/share/java/libgcj-java-placeholder.sh in the alternatives stands for the command "java" is 100. This value is higher than that of sun's java which you can download from sun's site. The priority of sun's java is 3. There are many people who say that they installed java from sun's site, but that they can't run them by typing "java" in terminals. So please decrease the priority value of gcj's java to 1 or 2. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Install libgcj-3.4.2-6.fc3 2.Install jdk-1.5.0_01-fcs which you can download from sun's site. 3.Run java from a terminal Actual Results: You get the output as follow: 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. Usage: gij [OPTION] ... CLASS [ARGS] ... to invoke CLASS.main, or gij -jar [OPTION] ... JARFILE [ARGS] ... to execute a jar file Try `gij --help' for more information. Expected Results: You get the output as follow: Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -d32 use a 32-bit data model if available -d64 use a 64-bit data model if available -client to select the "client" VM -server to select the "server" VM -hotspot is a synonym for the "client" VM [deprecated] The default VM is client. -cp <class search path of directories and zip/jar files> -classpath <class search path of directories and zip/jar files> A : separated list of directories, JAR archives, and ZIP archives to search for class files. -D<name>=<value> set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version:<value> require the specified version to run -showversion print product version and continue -jre-restrict-search | -jre-no-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] enable assertions -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] disable assertions -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:<libname>[=<options>] load native agent library <libname>, e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:<pathname>[=<options>] load native agent library by full pathname -javaagent:<jarpath>[=<options>] load Java programming language agent, see java.lang.instrument Additional info:
If you want to use Sun's JVM, your best bet is to build a JPackage starting from their .nosrc.rpm. Installing the resulting RPM will cause Sun's VM to own the java tools in /usr/bin. Otherwise, if you just want to use Sun's RPM, you'll need to put $JAVA_HOME/bin at the start of your PATH. In general, you should put any custom binary directory at the start of your PATH to ensure that custom binaries take precedence over system-default ones. Note that in Fedore Core 4 test 1, you may not need Sun's JVM anymore; java-1.4.2-gcj-compat and java-1.4.2-gcj-compat-devel wrap the GCJ toolset to provide JPackage-compatible Free Software runtime and development environments. Give them a try! Closing.
