Sun JDK Install Quesiton

[R0b0ty]

Hi, all.

I have a program that requires Sun's Java (JDK) - it explicitly states that it's not fully compatible with OpenJDK. I found several posts on how to install Sun's JDK.

My question is this... do I need to uninstall the Fedora default OpenJDK? I'm currently running Fedora 17, 32-bit.

Answer: Yes you can have multiple java versions installed.

I have tried to install with the command:
rpm -ivh jdk-7u11-linux-x64.rpm

This is normal output from the Sun/Oracle JRE/JDK rpm install. You can safely ignore those "Error:" lines.
What does "java -version" report now?
If it's still reporting the openJDK java, you'll need to run the "alternatives --config java" command to make the Sun/Oracle java your default. You might want to run "alternatives --display java" first, to insure the Sun/Oracle java got installed into alternatives.

This guide should work for the JDK package as well as the JRE package, just the rpm package names are different.

[obsidiana]

I have done all this, and still having a message indicating
"No existe una aplicación instalada para los archivos «ejecutable».
¿Quiere buscar una aplicación para abrir este archivo?"
"There is no apprilcation installed for the file..."
or something like that

I have included some outputs to make it more informative, sorry for the extension.

Is there something lacking?

[PabloTwo]

It appears you have everything setup OK. You would need to add the line export JAVA_HOME="/usr/java/jdk1.7.0_11" to your user ~/.bashrc and/or /root/.bashrc file to make it persistent.

You may need to disable the icedtea-web browser plugin in your browser so it doesn't conflict with the libnpjp2.so plugin. You could also just "yum erase icedtea-web" assuming you have it installed.

Thanks Pablo, how do I export this value to the mentioned files?
can I copy and paste into the files?
I which section?

I am trying to start XMind: a Java application based on Eclipse

[obsidiana]

I still don't have it working

[obsidiana]

Please, I still have not working Java in my system, there are a lot of very important things I cannot do, can someone help me?

"Java" doesn't appear as an "application to open" the programs I need, for example XMind and ArgoUML.

[nonamedotc]

Did you try using openJDK and see if your programs work?

This is the package name - java-1.7.0-openjdk.x86_64.

[smr54]

Rather than the ifnot true line, try the mjmwired guide (linked at the top of the page among the setup guides. )

http://www.mjmwired.net/resources/mj...-f18.html#java

That has always worked for me

[PabloTwo]

Although this guide is for installing Oracle's jre in F17, it can be adapted to install the jdk package. Perhaps it can help you.

Obsidiana:

All apear to be good.


Get a console or terminal and go to directory wher .jar file is:

example:

cd /home/obsidiana/whatever

Then type:

java -jar whateverfile.jar

Tell us if it works

If you want to see what java are you using try:

java --version

HTH

[obsidiana]

Thanks to you, all,
I have no "jar" file, the file used to startup the application is named "XMind" with no extension
when I try to open file, it appears an error message indicating it doesn't exist an installed application for the file(s) "executable"

I have Eclipse running and the following java program is selected:
/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
(obtained with the
alternatives --config java
command
whenever I select another program, "Eclipse fails to start

Thanks,
I have followed the tutorial, and now I have installed the newest java runtime, I have selected it (option 5)
But still, my Fedore doesn't recognize Java programs.
I even don't see an option in Nautilus to associate Java with the file

You can click on a jar file in your file manager, then from its menu, there should be a "Open With..." entry. Select that and type into the form "java -jar" and it will associate *.jar files with "java -jar" . From that point clicking on a jar file, for example "xyz.jar" will run:

java -jar xyz.jar

I got that to work in KDE with Dolphin File manager. But one problem with that is that it won't pass any special arguments to the main class. Usually java apps use a front end script (named "runprogram" in my example below) to give you a place to add and edit the arguments, then it runs something like:

#!/bin/sh
# runprogram

# DEBUG=0
DEBUG=1

JAVA="${JAVA_HOME}/bin/java"
exec "${JAVA}" -jar program.jar "${DEBUG}" "$@"

by running "runprogram argument1 argument2"

So just clicking on "program.jar" in the file manager would not have a way to correctly pass the option "DEBUG" nor the arguments lined up in "$@" which here would be "argument1 argument2". But sometimes all you need is: java -jar filename.jar so that would be fine

Probably the XMind object is a shell script that sets up and runs the java stuff.

If you can run:

file XMind

in the directory containing it and post the results here we might be better able to assist.
