[Solved]Java/OpenLazslo installation : Java_home variable not defined

[kln]

Hi
I know this has been posted countless times but it doesn't seem to work for me.
I am installing Java SDK (in order to install OpenLaszlo). And here's what I get when I try to run the script to make OL working :

$/usr/local/lps-4.3.0/Server/tomcat-5.0.24/bin$ sudo ./startup.sh
The JAVA_HOME environment variable is not defined
This environment variable is needed to run this program

I have installed java ($sudo aptitude install sun-java6-jdk sun-java6-doc sun-java6-demo), agreed the agreement by downloading the doc to /tmp from Sun's website ; I did this to select Java as default ($sudo update-java-alternatives -s java-6-sun).
I have added this in /home/.bashrc

if [ -d ~/bin ] ; then
  PATH=~/bin:/usr/lib/jvm/java-6-sun/jre/bin:"${PATH}"
fi
export JAVA_HOME=/usr/lib/jvm/java-6-sun

output of commands :

$ update-java-alternatives --list
java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk
java-6-sun 63 /usr/lib/jvm/java-6-sun

$ java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)

$ which java
/usr/bin/java

which is strange because it seems like the one it should be is /usr/lib/jvm/...

I don't understand much of this, just trying to figure out the specific line which will end this installation !
thanks in advance

Re: Java installation : Java_home variable not defined

The Tomcat Server still needs the JAVA_HOME.

I suggest you open the ~/.bash_profile and add the following line

export JAVA_HOME=/usr/lib/jvm/java-6-sun

[kln]

Re: Java installation : Java_home variable not defined

I have this same very line in ~/.bashrc
I don't have a ~/.bash_profile, but in ~/.profile, it does include ~/.bashrc
I think the problem is elsewhere because JAVA_HOME looks defined :

$ echo $JAVA_HOME
/usr/lib/jvm/java-6-sun

This is ~/.profile, I copied an extract of ~/.bashrc above.

# if running bash
if [ -n "$BASH_VERSION" ]; then
  # include .bashrc if it exists
  if [ -f "$HOME/.bashrc" ]; then
	. "$HOME/.bashrc"
  fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
  PATH="$HOME/bin:$PATH"
fi

Re: Java installation : Java_home variable not defined

You are running startup.sh with sudo which means you aren't using your ~/.bashrc file but the one for root. Try adding JAVA_HOME to /etc/profile and your problem should go away. The other option is run startup.sh as yourself instead of root.

Re: Java installation : Java_home variable not defined

Hi
I didn't really understand your reply, but I tried $./startup.sh (without sudo) and it works. I think it does because my OpenLazslo folder is in /home and not in /usr/local where at some point superuser privileges would be required (to run catalina.sh)

My former OL apps are working as well, which is great !
Many thanks

Re: [Solved]Java/OpenLazslo installation : Java_home variable not defined

It has nothing to do with /home or /usr/local. The only time you run Tomcat as root is when you choose a port number lower than 1024 which requires root permissions on Linux; otherwise, you can run it as any user with permissions to the directory and files. The important thing to remember is when you issue a command with sudo you are not getting your shell environment unchanged. I never remember all the rules but they cover the details in the man page for sudo. Observe the difference when typing env versus sudo env in a terminal. That should help clarify some of your confusion.
