DO NOT use Java 1.7. They are released with known bug that can wreck
your database or something similar nasty.
Solution should be:
2. In your Firefox browser, go to Edit-> preferences-> Applications, and
in Content Type select the option "use other" for jnlp files
3. In the dialog box, select the "javaws" file location (for me, it was
located in "/usr/java/jre1.6.0_16/bin")
Bellow is additional info and my notes on how to install Java for Firefox.
Here are my notes on installing Java JRE on CentOS:
Java JRE on CentOS 6 i 5
1. yum install jre
2. ## java ##: alternatives --install /usr/bin/java java
/usr/java/jre1.6.0_27/bin/java 20000
## javaws (32-bit only) ##: alternatives --install /usr/bin/javaws
javaws /usr/java/jre1.6.0_27/bin/javaws 20000
## Java Browser (Mozilla) Plugin 32-bit ##: alternatives --install
/usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so
/usr/java/jre1.6.0_27/lib/i386/libnpjp2.so 20000
## Java Browser (Mozilla) Plugin 64-bit ##: alternatives --install
/usr/lib64/mozilla/plugins/libjavaplugin.so libjavaplugin.so.x86_64
/usr/java/jre1.6.0_27/lib/amd64/libnpjp2.so 20000
commands 64-bit:
alternatives --install /usr/bin/java java /usr/java/jre1.6.0_27/bin/java
20000
alternatives --install /usr/lib64/mozilla/plugins/libjavaplugin.so
libjavaplugin.so.x86_64 /usr/java/jre1.6.0_27/lib/amd64/libnpjp2.so 20000
Do not use it blindly, select what you are installing (JRE/javaws, 32/64
bit) and fix the commands accordingly.
Older notes but with JDK:
Java na CentOS-u i Firefox
1. yum install java
2. Now you need to add the Java you have installed to the list of
alternatives for the java executable:
/usr/sbin/alternatives --install /usr/bin/java java
/usr/java/latest/bin/java 2
Note: There is two - (hypen) before install.
Note: Tinker with /usr/java/latest/bin/java if you do not have Java
installed at this location. In other words change it to point to the
location of your installed Java executable from Sun.
3. Now configure alternatives to select the latest Java executable under
/usr/java:
/usr/sbin/alternatives --config java
Check the version of Java to ensure that it is from Sun:
java -version
For example, this is the output I get:
java version "1.6.0_16″
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
Go to /usr/lib64/mozilla/plugins:
cd /usr/lib64/mozilla/plugins
or
cd /usr/lib/mozilla/plugins
4. Create a symbolic link to libnpjp2.so (Firefox plugin for Java):
ln -s /usr/java/latest/lib/amd64/libnpjp2.so
or
ln -s /usr/java/latest/lib/i386/libnpjp2.so
Note: The above is applicable for JDK installation. For JRE it is likely
to be:
ln -s /usr/java/latest/lib/amd64/libnpjp2.so
or
ln -s /usr/java/latest/lib/i386/libnpjp2.so
5. Restart Firefox and type the following in URL field and press Enter:
about:plugins
You should now see a section titled Java(TM) Plug-in 1.6.x
You are done installing Java Plugin / Applet support in Firefox on CentOS 5.
ln -s /usr/java/latest/plugin/i386/ns7/libjavaplugin_oji.so u
/usr/lib/mozilla/plugins

The howto I found:
1. Install an official Java for Linux (from the SUN site, )
2. In your Firefox browser, go to Edit-> preferences-> Applications, and
in Content Type select the option "use other" for jnlp files
3. In the dialog box, select the "javaws" file location (for me, it was
located in "/usr/java/jre1.6.0_16/bin")
4. Wery important to select the "javaws" from official SUN package, and
not from the package with Linux java distribution - it's not works!
First try WITHOUT No 4. and avoid No 1., instead install
"java-1.6.0-openjdk" and in java
