Unable to execute a .jar file in Ubuntu

[alargorak]

Technicfailure.jpg

Hello, I am new to Ubuntu. I have installed oracle java 7 and 8 runtime. I am unable to get this jar file to respond at all, and i cannot double click it.
I have marked it in the properties to allow executing as a program.

java -version gives me
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
Java HotSpot(TM) Server VM (build 25.40-b25, mixed mode)


I am sure i am making some new user mistake, please help me determine what it is so that I can learn for the future :]

Have you tried doing "java -jar <filename>"? I have jar files and that's how they get run.

Yes, I have. The image I enclosed is the result of "java -jar TechnicLauncher.jar".

I use the OpenJDK runtime v1.7.0_79 in Ubuntu 15.04 and jar files open just fine.

Don't use Oracle java, so can't offer any suggestions.

Maybe this will help-

To clarify, I can open other .jar files without a problem. I can double click Minecraft.jar, and it runs without fail. It's just this other .jar file that seems to be giving me the trouble, but it's the latest release from technicpack.net, so I am pretty sure the error is on my end somehow.

Try

sudo apt-get install libxi6

[alargorak]

I just did that, it says libxi6 is already the newest version; it did however recommend i do "apt-get autoremove" which i did.

I downloaded the TechnicLauncher.jar file from http://www.technicpack.net/download
It will open here via terminal with "java -jar TechnicLauncher.jar" or right click and open with "Oracle java runtime"

I noticed your pick in post #1 seemed to indicate it couldn't find a 32bit link ie unsatisfiedlinkerror /home/me/lib/i386/lib...

I am running Ubuntu 14.04 64bit with java-8-oracle set as default java. INSTALL ORACLE JAVA 8 IN UBUNTU
What do these commands give you?

lsb_release -a
uname -a
sudo update-alternatives --config java

eg my output...

There are 3 choices for the alternative java (providing /usr/bin/java).

Press enter to keep the current choice[*], or type selection number:

All works here.
The java app sets a default directory, downloads some files then presents a login window.

Here is the results of what you requested; it seems I didn't have LSB, which after checking the repository, is Linux Standard Base, so i installed just now.

After getting the same error message attempting to run the launcher from terminal, i had the earth-shattering idea to, instead of "java -jar TechnicLauncher.jar", to try "sudo java -jar TechnicLauncher.jar".

It worked.

The error message seemed to be either telling me the file wasn't there or I didn't have permissions, solved by using sudo. Wow.

Thank you so much for the help!

[CantankRus]

Shouldn't need sudo and not sure if it's even wise to use with a java app that connects to the net and downloads.
I would be checking permissions of my files and folders.
I don't have lsb installed but do have lsb_release installed by default.

Main difference I can see is you have java-7-oracle set as default java where I have java-8-oracle.
