trouble running Eclipse

carlyno · 04-01-2007, 08:22 AM

Hi all !
I've just installed Eclipse, with the required packages obviously, but when I run the IDE.... error message : "A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:/usr/lib/j2sdk1.4-sun/bin/java"
Well, the message is clear enough: no JRE or JDK... but :

Code:

# aptitude search jdk
p   sun-java5-jdk                   - Sun Java(TM) Development Kit (JDK) 5.0
c   sun-java6-jdk                   - Sun Java(TM) Development Kit (JDK) 6
# aptitude search jre
p   docbook-jrefentry               - DocBook XML JRefEntry DTD
p   sun-java5-jre                   - Sun Java(TM) Runtime Environment (JRE) 5.0c   sun-java6-jre                   - Sun Java(TM) Runtime Environment (JRE) 6 (

and

Code:

apt-get install sun-java6-jdk
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances... Fait
sun-java6-jdk est déjà la plus récente version disponible.
0 mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à jour.
# apt-get install sun-java6-jre
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances... Fait
sun-java6-jre est déjà la plus récente version disponible.
0 mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à jour.

meaning that sun-java6-jre and sun-java6-jdk are already installed and are the most recent versions.
So how come Eclipse is looking for j2sdk1.4. I've checked the /usr/lib/ directory:

Code:

/usr/lib/java# ls
swt3.2-gtk.jar  swt-gtk.jar  swt.jar

Any idea about this ? Is there a specific way to install the IDE, besides using synaptic ?

Well, the missing directory is obviously the culprit. Figure out what the contents of that dir should be, find the corresponding dir in your java-tree and create a sym-link from that to /usr/lib/j2sdk1.4-sun/bin/java Like this:

Code:

ln -s </full/path/to/dir> /usr/lib/j2sdk1.4-sun/bin/java

Thanx Dutch Master for your answer.... I have to find out where the java tree is..; I first thought of /usr/lib/java, but if it so, well there's no j2sdk1.4-sun. So it's gotta be some place else; I'll check closer, but if you'd have a clue, tell me

If you don't mind using synaptic, you can click on the name of the already installed package and then click on 'properties'. There you can see a list of all the files installed. The directory you're looking for would have to be one of those...
