Check it topi in the centos forum I was with a problem with fedora-ds and it was perfect. Regards Jose Grid Systems http://www.centos.org/modules/newbb/viewtopic.php?topic_id=2903 Reconfiguring CentOS 4's default Java configuration. This is done as root or equivalent and is for jre adjust for jdk where needed; First remove /var/lib/alternatives/java file by typing; rm /var/lib/alternatives/java When asked press the 'y' key, Now to create the new (corrected) alternatives file for java type the following commands as root (modify for jdk as needed); /usr/sbin/alternatives --install /usr/bin/java java /usr/lib/jvm/jre-1.4.2-gcj/bin/java 1 /usr/sbin/alternatives --install /usr/bin/java java /usr/java/j2re1.5.0_06/bin/java 2 /usr/sbin/alternatives --config java You should now see for example: There are 2 programs which provide 'java'. Selection Command ----------------------------------------------- 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java *+ 2 /usr/java/j2re1.5.0_06/bin/java Enter to keep the current selection[+], or type selection number: Type: <choose 1 or 2> In the example above java is already configured correctly [*+ 2] to use Sun's Java, no changes are needed, just press the Enter key here. If you have been following the instructions then you should have the same results (version numbers may be sightly different). Now type; /usr/sbin/alternatives --display java You should see for example; java - status is manual. link currently points to /usr/java/j2re1.5.0_06/bin/java /usr/lib/jvm/jre-1.4.2-gcj/bin/java - priority 1 /usr/java/j2re1.5.0_06/bin/java - priority 2 Current `best' version is /usr/java/j2re1.5.0_06/bin/java. Next you might want to create (or edit) /etc/profile.d/java.sh file, example below; export JAVA_HOME="/usr/java/jre1.5.0_06/bin" export JAVA_PATH="$JAVA_HOME" export PATH="$PATH:$JAVA_HOME" When done creating or editing the file type; source /etc/profile.d/java.sh Now any user root or other wise should be able to use the command; which java and the results should read something like; /usr/java/jre1.5.0_06/bin/java Also any user root or other wize should be able to use the command; java -version and the results should read something like; java version "1.5.0_06" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05) Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing) That's it, all done. -----Mensaje original----- De: centos-bounces at centos.org [mailto:centos-bounces at centos.org] En nombre de Ted Miller Enviado el: Domingo, 06 de Agosto de 2006 08:14 a.m. Para: CentOS mailing list Asunto: [CentOS] Official Java What is the official method to install Java on Centos?
