JAVA_HOME / JRE_HOME variable missing

[raiko]

Hi, I've installed OpenKM 6.2 community on Ubuntu 12.04 LTS. After issued this command:

Code: Select all

./opt/openkm/tomcat/bin/catalina.sh start

Following error has returned:

Code: Select all

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

From my understanding, OKM installer has JAVA bundled and I shouldn't need to install JAVA by my own. How can I fix it?

Thank You!

I would suggest to install 1.6 Java version for Ubuntu, and test if it works.

I followed this page to install JAVA 1.6 and with this errors:

Code: Select all

./jre-6u31-linux-i586.bin: line 2: head: No such file or directory

I also tried to add the JRE_HOME variables manually from terminal:

Code: Select all

JRE_HOME=/opt/openkm/java

And catalina returns the same error.

Install jdk 1.7 for tomcat to work!

[raiko]

I didn't try JDK 1.7 because somewhere mentioned OKM is not compatible with it. Anyway, thanks again shaardu!

[shaardu]

Try with jdk 1.6 atleast...it works fine ,also you need to set the environment variable!

[raiko]

I tried both, see my initial post. Or we are not talking about the same thing?

For install java in ubuntu take a look here https://help.ubuntu.com/community/Java

About openkm installer, comes with java but this kind of configuration is only to make openkm starting and initial configuration more easy. Really the java installed by openkm bundle does not install at your OS in a normal way, only is exploded and used by openkm start scripts. Here I suppose you installed openkm with installer not .zip

[raiko]

Yes, I installed openkm with the installer. Unlike the windows version, I don't see there is any starting script. I have seen there was 2 scripts with "desktop" extension, but they have no action after double-click.

Since I have removed ubuntu. This thread can be closed.

Thanks for all the inputs.

Seems has been some problem during installation process. Anyway if you want to test other time script to execute from terminal are:

Code: Select all

tomcat/bin/catalina.sh start
tomcat/bin/catalina.sh stop

[raiko]

This exactly what I did. Pls see my initial post above. Thanks!

[jllort]

Seems has been some problem with your installation ? take a look in openkm folder you got java folder and then take a look at tomcat/setenv.sh that JAVA_HOME variable is correctly set, otherside change it.
