 Posted: Mon Dec 09, 2002 2:17 pm Post subject: Java and profile.env |
 |
|
During my install, something required java to be installed - it installed the blackdown jre. Now I need to use Sun j2sdk 1.41 so I decided to go it alone and just unmerge the jre and java-config and install Java 1.4 into /opt outside of portage controll.
However env-update is still populating my profile.env with JAVA_HOME and other JAVA related variables - all of which point to the now unmerged blackdown JRE.
What needs to be done to remove the remnants of the previous JRE. There are no pending config updates, so it must be something still on the filesystem somewhere - but where do I start looking?
Thanks.
David. |

Post-installation question, moved from Installing Gentoo.

If you've finished the install guide, look somewhere else. But if you're still working your way through it, or just need some info before you start your install, this is the place. |

OK - Updating my own question.
Found the key - /usr/bin/java-config - which is the script that digs around in various /etc/env.d/java files to setup the system vm config.
I think if I can find what a vailid /etc/env.d/java/*** file looks like I'll be
set - I don't really want to have to DL a vm just to find this out, so if someone will paste one here for me that would be great.
I shold then be able to set up a system vm that java-config will like, and portage will be none the wiser that a VM has been installed outside of it's control.
Thanks,
David. |

I have three files that may be of interest.
First, /etc/env.d/20java
| Code: |
# Autogenerated by java-config 0.2.5
# Cmd: /usr/bin/java-config --set-system-vm=blackdown-jdk-1.3.1
JAVA_HOME=/opt/blackdown-jdk-1.3.1
CLASSPATH=/opt/blackdown-jdk-1.3.1/jre/lib/rt.jar:.
JDK_HOME=/opt/blackdown-jdk-1.3.1
JAVAC=/opt/blackdown-jdk-1.3.1/bin/javac
PATH=/opt/blackdown-jdk-1.3.1/bin:/opt/blackdown-jdk-1.3.1/jre/bin
ROOTPATH=/opt/blackdown-jdk-1.3.1/bin:/opt/blackdown-jdk-1.3.1/jre/bin
LDPATH=/opt/blackdown-jdk-1.3.1/jre/lib/i386/:/opt/blackdown-jdk-1.3.1/jre/lib/i386/native_threads/
MANPATH=/opt/blackdown-jdk-1.3.1/man
|
Second, /etc/env.d/java/20blackdown-jdk-1.3.1
| Code: |
# Copyright 1999-2002 Gentoo Technologies, Inc.

MANPATH=/opt/blackdown-jdk-1.3.1/man
ENV_VARS="JAVA_HOME CLASSPATH JDK_HOME JAVAC ADDPATH ADDLDPATH MANPATH"
|
And lastly, /etc/env.d/java/20blackdown-jre-1.3.1
| Code: |

JAVA_HOME=/opt/blackdown-jre-1.3.1
CLASSPATH=/opt/blackdown-jre-1.3.1/lib/rt.jar

MANPATH=/opt/blackdown-jre-1.3.1/man
ENV_VARS="JAVA_HOME CLASSPATH JRE_HOME ADDPATH ADDLDPATH MANPATH"
|
Hope this helps.

Thanks, now it's working.
OK the way to do this is to:
1. Make sure java-config is merged
2. Download your favorite vm and install somewhere (/opt is good)
3. Setup a 'system-vm' file - in /etc/env.d/java - it needs to look like one of the files posted above. Call it 20<my-java-name> (where obviously <my-java-name> is some ID you specify. Edit it to point to the appropriate places
4. Run java-config --set-system-vm=<my-java-name> This is what generates the /etc/env.d/20java file
5. Run env-update, Logout/login and you should be good to go
You may need to do something to fake out portage that you have a valid jdk installed (how do you do that?). Or use --nodeps a lot....
I've just managed to install ant and jedit using the above approach.
Thanks for the files.
