jre has been installed.

This package i saw isn't present.

How and where did you check?

**kingsmasher1** · 03-07-2011

Yes, it shows jre is installed, but when i do "java -version", it gives error saying "Not found".

I am not able to install new jre too.

Please help me if you can.

probably java directory wasn't added to path variable

I'm not sure where the jre is installed to, but I imagine that its somewhere in /opt

use rpm -ql jre so you can see where it is installed

you will want to set JAVA_HOME environment variable to the base directory, and then add JAVA_HOME/bin to path

i would just edit user .bashrc file to do this, example of /opt/java:

Code:

export JAVA_HOME=/opt/java
export PATH=${JAVA_HOME}/bin:$PATH

The strange thing is that running "rpm -ql jre" shows a lot of things like:

Code:

/etc
/etc/.java
/etc/.java/.systemPrefs
/etc/.java/.systemPrefs/.system.lock
/etc/.java/.systemPrefs/.systemRootModFile
/etc/init.d/jexec
/usr
/usr/java
/usr/java/jre1.6.0_24

/usr/java/jre1.6.0_24/THIRDPARTYLICENSEREADME.txt
/usr/java/jre1.6.0_24/Welcome.html
/usr/java/jre1.6.0_24/bin
/usr/java/jre1.6.0_24/bin/ControlPanel

/usr/java/jre1.6.0_24/bin/java_vm
/usr/java/jre1.6.0_24/bin/javaws
/usr/java/jre1.6.0_24/bin/jcontrol
/usr/java/jre1.6.0_24/bin/keytool
/usr/java/jre1.6.0_24/bin/orbd

But when i do:

Code:

cd /usr/java/ [Enter]
bash: cd: /usr/java: No such file or directory

Please help me. Why is it showing, no such file or directory, where "rpm -ql" shows it is present?
Please help me.

i don't think RPM file was properly installed, just uninstall RPM and then reinstall
