Installing the JDK under Linux requires similar steps, but because Linux is such a different creature, you'll do them in very different ways than Windows requires. Getting the Binary DistributionPoint your browser to http://java.sun.com/j2se/1.3/download-linux.html and click Continue under Red Hat RPM Shell. Accept the license agreement, and choose a server to download from. Save the file in the /tmp/ directory. Installing the DistributionAs root, cd to /tmp and type ./j2sdk-1_3_1_01-linux-i386-rpm.bin. Agree to the license by entering yes. This creates a file called jdk-1.3.1_01.i386.rpm in /tmp. Install it using rpm: [root@linux tmp]# rpm install jdk-1.3.1_01.i386.rpm This unpacks the distribution as /usr/java/jdk1.3.1_01. Setting JAVA_HOME and PATHCreate the file /etc/profile.d/jdk.sh as root with the following content: PATH="$PATH:/usr/java/jdk1.3.1_01/bin" JAVA_HOME=/usr/java/jdk1.3.1_01/ export JAVA_HOME PATH As root, issue the following command: chmod a+x /etc/profile.d/jdk.sh Testing the Linux JDK InstallationLog out and log back in again; then type java. You should see the following: [turner@linux turner]$ java Usage: java [-options] class [args...] (to execute a class) or java -jar [-options] jarfile [args...] (to execute a jar file) where options include: -client to select the "client" VM -hotspot is a synonym for the "hotspot" VM [deprecated] -server to select the "server" VM -classic to select the "classic" VM If present, the option to select the VM must be first. The default VM is -client. -cp -classpath <directories and zip/jar files separated by :> set search path for application classes and resources -D<name>=<value> set a system property -verbose[:classgcjni] enable verbose output -version print product version and exit -showversion print product version and continue -? -help print this help message -X print help on non-standard options If you don't get this output, do echo $PATH and make sure that the /usr/java/jdk1.3.1/bin directory is part of your path. If it is not, you should recheck the step in which you set up PATH . |
