trouble installing jdk1.5.0_02

mayasedai · 04-27-2005, 11:56 AM

i have installed the jdk following instructions on the java.sun.com/j2se/1.5.0/install-linux.html
the rpm was installed, there were no error messages, but the 'java -version' test failed : command not found

i treid to set the path by adding to /etc/profile the lines:

Code:

PATH="$PATH:/usr/java/jdk1.5.0_02/bin:."
export PATH

didnt work

i then chaged the path as directed on
www.linux.com/howtos/MMBase-Inst-HOWTO/x117.shtml
and created the java.sh file in /etc/profile.d

the contents of the file are

Code:

if ! echo ${PATH} | grep -q /usr/java/jdk1.5.0_02/bin ; then
    export PATH=/usr/java/jdk1.5.0_02/bin:${PATH}
    fi
  if ! echo ${PATH} | grep -q /usr/java/jdk1.5.0_02/jre/bin ; then
    export PATH=/usr/java/jdk1.5.0_02/jre/bin:${PATH}
    fi
  export JAVA_HOME=/usr/java/jdk1.5.0_02
  export CLASSPATH=.:/usr/java/jdk1.5.0_02/lib/tools.jar:/usr/java/jdk1.5.0_02/jre/lib/rt.jar

i also set its access rights with

Code:

 chown root:root /etc/profile.d/java.sh
 chmod 755 /etc/profile.d/java.sh

it still doesnt work = 'java' gives command not found

how do i get this working??

did you restart your session, or source /etc/profile? after you change it you'll need to run it. does your path say it has the right directories.

echo $PATH

does this give you a string with the directories added? i alwasy add the lines in my ~/.bashrc file. I also thing that your classpath just needs to have the directory /usr/java/jdk1.50_02/lib in it.

thanks, on running and restarting it works.

echo gives:

Code:

[maya@172 maya]$ echo $PATH
/usr/java/jdk1.5.0_02/jre/bin:/usr/java/jdk1.5.0_02/bin:/usr/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin/:/usr/games:/usr/java/jdk1.5.0_02/bin:.:/home/maya/bin

i'm not sure how to code that (i just copied the previous bit from somewhere)
should i just add to etc/profile

Code:

PATH="$PATH:/usr/java/jdk1.5.0_02/lib:."
export PATH

do i need to do this even tho the java.sh file has the line

Code:

export CLASSPATH=.:/usr/java/jdk1.5.0_02/lib/tools.jar

Code:

if ! echo ${PATH} | grep -q /usr/java/jdk1.5.0_02/bin ; then
    export PATH=/usr/java/jdk1.5.0_02/bin:${PATH}
    fi
  if ! echo ${PATH} | grep -q /usr/java/jdk1.5.0_02/jre/bin ; then
    export PATH=/usr/java/jdk1.5.0_02/jre/bin:${PATH}
    fi
  export JAVA_HOME=/usr/java/jdk1.5.0_02
  export CLASSPATH=.:/usr/java/jdk1.5.0_02/lib/tools.jar:/usr/java/jdk1.5.0_02/jre/lib/rt.jar

i would change the last line to

Code:

export CLASSPATH=.:/usr/java/jdk1.5.0_02/lib

you could just leave it as-is right now. it may work. however, if it is a problem, you will be getting some erros that look something like this:

Exception in thread "main" java.lang.NoClassDefFoundError: xxxxxxxx

in which case, you'll just need to make the change above.

thanks!

you don't need to specify the classpath and if i were you i would leave it alone, you really don't need it unless you are using "some kind of experimental jvm"

sirclif · 04-29-2005, 05:20 PM

are you sure? i get errors unless i specify it. doesn't it tell the system where the 'root' folder is for all the java packages you are going to call?

No, because it knows they're relative to the location of the java binary (i.e. at ../lib) or whatever.

Here is a copy of my java.sh, it works fine on Slack, Fedora and CentOS,

Code:

#!/bin/sh
export JAVA_HOME=/opt/java
export MANPATH="$MANPATH:/opt/java/man"
export PATH="$PATH:/opt/java/bin:/opt/java/jre/bin"

Just change the paths so that they are the same as you java installation or create a symlink from your java diectory to /opt/java, log out and in again and java should work.
