Trying to set Java JDK 7 as default application for .jar files & have hit a snag

Java does not appear in the list of usable programs. I tried using the 'find programs online' button but it spit out an error (in a GUI text box):

GDBus.Error:org.freedesktop.DBus.Python.xdg.Except ions.ParsingError: Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 489, in _inline_callbacks

ParsingError: ParsingError in file '/usr/share/app-install/desktop/workrave:workrave.desktop', Invalid line: - RSI (Repetitive Strain Injury) oraz wspomaga rekonwalescencj\u0119

I'll note that I just wiped my hard drive and installed Ubuntu 13.04 a few weeks ago. I update as updates are supplied.
I installed JDK 7 using the software center.

It should be already the default app by default.

Nevertheless, you could try setting it again as the default jvm, something along the lines of

Code:

---

sudo update-java-alternatives -s java-1.7.0-openjdk-i386

---

you can see the list of installed jvms like this

Code:

---

sudo update-java-alternatives -l

---

Hope that helps.

Odd. I have

"java-1.7.0-openjdk-i386 1071 /usr/lib/jvm/java-1.7.0-openjdk-i386"

but when i try

sudo update-java-alternatives -s java-1.7.0-openjdk-i386 it returns:

I take that as that it cannot find the specified file. :confused:

I have 64-bit 12.04, but do not even see those (files or directories?) in a similar location or cannot find them with the "locate" command (like "locate appletviewer"):

Code:

---

efflandt@xps8100-1204:~$ ls /usr/lib/jvm/java-1.7.0-openjdk-amd64/bin
java  java-rmi.cgi  javaws  keytool  orbd  pack200  policytool  rmid  rmiregistry  servertool  tnameserv  unpack200

But the only thing I use java for is minecraft client or server (or something else on a Raspberry Pi that needed parameters), so I used a script to launch those until I figured out how to do it in a launcher. For example this is what I use in a desktop or Unity launcher for the new beta minecraft launcher:

Code:

---

sh -c 'java -Xmx2G -Xms1G -jar ~/MC-client/MinecraftDev.jar'

---

I do not know how to have a .jar automatically execute when you double click on it (maybe it needs execute permission) because even an executable script then asks if you want to run it or open it in a text editor. By default when I right click on a .jar the default is "Open With Archive Manager"

But it also offers:
Open With Archive Mounter
Open With OpenJDK 7 Runtime
Open With Other Application

In synaptic there is a file-type utlity called "assogiate".

Code:

---

sed -ie 's|\(Applications]\)|\1\napplication/java-archive=openjdk-7-java.desktop|' ~/.local/share/applications/mimeapps.list

Someone knows his Ubuntu. Thanks!
