hi, i've download jave-based installer fro jedit from its website... but now the problem is ".jar" file opens up in Archive Manager program when I click on it...instead of running the auto-installer...

I think java -jar <filename> will work.

Update JRE...?

That looks like it's not a valid JAR file to me. You could unzip it and run the class files directly, perhaps.

I would think of a broken/uncompatible jdk/jre.

What reports: "java -version" ?

Open the file with some archive manager. Check if a file /META-INF/MANIFEST.MF exists within that. Check whether this file contains the line "Main-Class: folder1.folder2.file". "folder1.folder2.file", of course, is just a placeholder of mine. Check whether the file /folder1/folder2/file exists in the archive.

If you've did that, and just nodded, "OK, exists", jedit42install.jar should be valid (which is likely). In this case, we'ld need to find out more about your Java version (as jlliagre suggested).

thx every1 for the replies

java -version:

Code:

[zixan@localhost ~]$ java -version
java version "1.4.2"
gij (GNU libgcj) version 4.1.1 20060525 (Red Hat 4.1.1-1)

I think there's a problem whith the gnu java installed on my system, as the file exists suggested by robbbert. I also installed java by sun (jre) using this tutorial but I think my system is not configuring it as the default java plugin..

jlliagre · 08-19-2006, 04:09 PM

Use the full path to where you have installed Sun's JRE, eg.

Code:

/opt/jre1.5.0_07/bin/java -jar jedit42install.jar

By the way, this is unrelated to the browser java plugin.

thanks jlliagre, finally got it running...

You could link /opt/jre1.5.0_07/bin/java to /usr/bin then you wouldn't have to type the full path. Or just include the /opt/jre1.5.0_07/bin/ in your profile path.

tangle, do you know how can I link through the terminal, as I don't have root access in GUI? Or, is there a way to have root access with normal login in GUI?

su
ln -sv

tangle · 08-19-2006, 07:59 PM

ln -s <file your want to link> <file you want to link to>

ln -s /opt/jre1.5.0_07/bin/java /usr/bin/java
