Cannot open .jar with right-click > open with "sun java 6 runtime"

[Savvas Radevic]

Trying to open jdownloader (www.jdownloader.org) JDownloader.jar with right-click > "open with".

$ sudo update-alternatives --display java
java - manual mode
 link currently points to /usr/lib/jvm/java-6-sun/jre/bin/java
/usr/lib/jvm/java-6-openjdk/jre/bin/java - priority 1061
 slave java.1.gz: /usr/lib/jvm/java-6-openjdk/jre/man/man1/java.1.gz
/usr/lib/jvm/java-6-sun/jre/bin/java - priority 63
 slave java.1.gz: /usr/lib/jvm/java-6-sun/jre/man/man1/java.1.gz
Current `best' version is /usr/lib/jvm/java-6-openjdk/jre/bin/java.

Works: JDownloader.jar > right-click > open with "openjdk java 6 runtime"
Does not work: JDownloader.jar > right-click > open with "sun java 6 runtime"

java in terminal and in an application launcher works though, e.g.:
java -jar /home/forger/jdownloader/JDownloader.jar

I think this causes the problem:

$ cat /usr/share/applications/sun-java6-java.desktop
[Desktop Entry]
Encoding=UTF-8
Name=Sun Java 6 Runtime
Comment=Sun Java 6 Runtime
Exec=@java_launcher@ -jar
Terminal=false

MimeType=application/x-java-archive;application/java-archive;application/x-jar;
NoDisplay=true

What's @java_launcher@ ?

[Savvas Radevic (medigeek)]

It looks like the debian/rules has this (from the diff.gz):

+debian/control: debian/control.in debian/rules
+ @cp -p debian/control debian/control.old
+ sed -e 's/@JRE@/$(p_jre)/g' \

+ debian/control.in > debian/control

But I think I don't see a sed command to replace "@java_launcher@" in file debian/JB-java.desktop.in

6.20dlj-1ubuntu3 was just released to lucid, now will there be another update against earlier released 6.20dlj-0ubuntu1.9.10 for karmic? I don't see the change note from lucid in the karmic pac. Heavy going today... ;)

[Savvas Radevic (medigeek)]

Confirming it's fixed for lucid. The launchpad janitor for some reason didn't update it.

[Savvas Radevic (medigeek)]

I think the karmic package is *not* affected:
