Problems installing Java SDK 1.5.0

harshnoise · 02-19-2006, 02:16 PM

Hi everyone, I'm trying to install the new JDK on my machine using the command

Code:

linux:> rpm -iv jdk-1_5_0_06-linux-i586.rpm

But there obviously needs to be some sort of configuration files adjusted because everything still points to version 1.4.2.

Any ideas where to start looking?

Thanks,

Anthony

Type 'which javac' to see where the javac you're using is. Sun's packages install each java version into a new directory, so chances are you just need to update your $PATH to point to the new java installation.

There are several ways to go:

1. Uninstall the previous (this is NOT necessary!):

2. Use "alternative --configure" to control which (of multiple JDK's) is the default:

3. Simply (as dmail suggested) set your environment to point to one or the other:

Many prefer to do this globally in /etc/profile or $HOME/.bashrc; I think there are advantages in a per-project "env.rc" file. The only "critical" one as $PATH. Other environment variables include
$JAVA_HOME
$JAVA_BIN
$CLASSPATH
etc etc
