[SOLVED] Java Woes: A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available ...

chytraeus · 11-08-2010, 04:17 PM

Hi,
I resized/moved my extended partition last night. slackware is on one of the logical partitions. Now I'm having some problems starting applications that need java such as moneydance and RSSOwl. When I try to run rssowl the following dialogue pops up:

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run RSSOwl. No Java virtual machine
was found after searching the following locations:
/usr/lib/RSSOwl/jre/bin/java
java in your current PATH.

Moneydance won't start and libreoffice barfs too.

Code:

set | grep -i java

returns:

JAVA_HOME=/usr/lib/java
MANPATH=/usr/local/man:/usr/man:/usr/lib/java/man:/usr/lib/java/man:/opt/plan9/man:/usr/lib/scala/man:/usr/share/texmf/man.

Java is not working in Opera either. I haven't checked the other browsers except for xxxterm which works fine with java.

I tried reinstalling jre and jdk which didn't help.

Could someone help?

Did you do a full install? If so, you should have the jre, and the jdk is in /extra on the DVD.

Sorry, should have read your post more thoroughly and noticed the bit about reinstalling them.

Hi,

bash: type: /usr/lib/qt/bin:/home/chytraeus/bin:/opt:/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin:
/usr/local/bin:/usr/local/sbin:/usr/games:.:/opt:/home/chytraeus/bin: not found

Okay libreoffice is working. I had simply run out of space on my data partition after last nights partition changes.

Java is working in Opera too. It's still not working for RSSOwl or Moneydance.

This feels like a problem I should be able to fix but I'm stuck.

I think that I have a java address in my path. It will have to wait until this evening before I can check it out.

From your first post it looks like java is not in your path anymore.

Code:

[tich@quackers:~] $ cat /etc/slackware-version 
Slackware 13.1.0
[tich@quackers:~] $ which java
/usr/lib/java/bin/java
[tich@quackers:~] $ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/java/bin:/usr/lib/qt/bin:/usr/share/texmf/bin:.

Hi,
How can I add it to my path?

Bertical · 11-09-2010, 07:54 AM

I think the java path should be set automatically on login by /etc/profile.d/jre.sh. If that file isn't there then maybe a reinstall of the JRE or JDK would fix it.

To set the path manually

Code:

PATH=$PATH:/usr/lib/java/bin

but it will be lost on reboot. Are you logging in as root as there is no default java path for the root account.

For me, I do a lot of development where I have to switch between java release branches. So I like to always manually install java and I segregate the releases in /opt.

To make this more permament, add it to your .bash_profile so every time you log in the path sets itself.

So, for me, currently my .bash_profile looks like this:

Code:

#Profile for logins
source ~/.bashrc

#aliases
alias ll="ls -alf"
alias cls="clear"
alias opt="cd /opt"
alias home="cd ~/"

#java dirs
export PATH=/opt/jdk1.6.0_22/bin:$PATH
export JAVA_HOME=/opt/jdk1.6.0_22/
export JRE_HOME=/opt/jdk1.6.0_22/
#export LD_LIBRARY_PATH=/opt/jdk1.6.0_22/lib:/opt/jdk1.6.0_22/jre/lib:$LD_LIBRARY_PATH

I have commented out the LD_LIBRARY because I didn't need it. You can choose to leave it in or not include it at all.

Hope this helps!

_O_

Thanks for the help everyone.

Thanks a ton Orwell, saved me lots of headache.
Seems like this needs to be done manually in Slack 13.1 x64.
