How to upgrade java?

pahidla · 01-13-2007, 08:59 AM

I figured the following ought to do it, but as you can see, it didn't. So how can I upgrade from 1.4.x to 1.6?

[af@i ~]# java -version
java version "1.4.2"

[af@i ~]# rpm -i jdk-6-linux-i586.rpm
Unpacking JAR files...
rt.jar...
jsse.jar...
charsets.jar...
tools.jar...
localedata.jar...
plugin.jar...
javaws.jar...
deploy.jar...

[af@i ~]# rehash

[af@i ~]# java -version
java version "1.4.2"

You don't really upgrade. You just download the new one (and delete the old one, but I would keep the old one for a while until you certain everything with the new one is working)

Thanks for the response. Actually I'm happy to wipe out the old one since I know from using the code on a different machine that everything works.

Would you be so kind as to give details on how to remove the old one and install the new one. (Please forgive me for not trying to become a linux admin guru, but instead looking for a quick fix.)

Thank you!

If you had installed the old java with rpm, you can look for it with:
# rpm -q -a | grep java
then to remove it
# rpm --erase <java package name>

If you didn't install with rpm, to remove the old java you have to know where it is. If you do, just remove the folder. If you dont do:
# updatedb
# locate java

This first command will take a while. The second command may produce a long list, but you should be able to see where the installation directory is.

rpm -u is for upgrade AFAIK. Perhaps you could try that.

Or deinstall old version and install new one as someone suggested should help.

Maybe you should check JAVA_HOME value of current user and check all files :
$ cd /etc
$ find . -type f | grep "java"
