Hi,
I am trying to install javain my machine but dont think its happening.

I d/led the java package from java website and kept it in /opt/java
then i ran ./jre-6u21-linux-i586-rpm.bin.

also added export JAVA_HOME=/opt/java/jre-6u21-linux-i586-rpm.bin/
export PATH="$JAVA_HOME/bin:$PATH"
in my /etc/profile.

Now when i verify my java installation online on java website it show missing plugin.

what should i do?

You need to put the plugin file in your browser's plugins directory. Did you read the instructions?

You have got your JAVA_HOME wrong.

By default Java is installed /usr/java/jdk<version>

yes its automatically created..
In my case, m using mozilla, so there is already a symbolic link created.
lrwxrwxrwx 1 root root 39 Sep 23 13:40 libflashplayer.so -> /usr/lib/flash-plugin/libflashplayer.so
in mozilla/plugin

Still not working.

Adobe Flash (libflashplayer.so) is not Java. You need the netscape or i386 java plugin from your java installation and symlink it in yourself most likely.

Shamelessly stealing from knudfl's post to me, try from terminal as root:

/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_21/bin/java /usr/sbin/alternatives --config java
.. and choose "sun".


This is the alternative knudfl gave that I used. Worked like a charm. Note that the link is to libbpjp2.so. MAKE APPRORIATE ADJUSTMENTS FOR YOUR INSTALL PATH AND jAVA VERSION


Firefox : You can just make a direct link like this :
cd /usr/lib/mozilla/plugins
# ln -s /usr/java/java-1.6.0-sun-1.6.0.21/jre/lib/i386/libnpjp2.so

can u please tell me which file to link to in /i386 if iam not using alternative option.

I realy dont know whats going wrong?
i d/led jdk-6u21-linux-i586.bin package from java site and kept in /usr/java.
Then i ran ./jdk..... and jdk1.6.0_21 was created in /usr/java.
creatd a soft link in mozilla/plugin
ln -s /usr/java/jdk1.6.0_21/jre/lib/i386/libjavaplugin_nscp_gcc29.so /u

Added
export JAVA_HOME=/usr/java/jdk-6u21-linux-i586.bin
export PATH="$JAVA_HOME/bin:$PATH"
to /etc/profile.
Restarted my computer, still installation is not complete. Now what should i do?

Firefox : You can just make a direct link like this -- (as root, in terminal):

change your director to : /usr/lib/mozilla/plugins

Once in that directory (in terminal, as root), type: ln -s /usr/java/java-1.6.0-sun-1.6.0.21/jre/lib/i386/libnpjp2.so



Like I posted above, that's what knudfl instructed, and it worked like a charm.

Thanks for help, its done. Just for me path is different.
ln -s /usr/java/jdk1.6.0_21/jre/plugin/i386/ns7-gcc29/libjavaplugin_oji.so

When ever i try to work with java plugin added up in mozzila plugin, firefox crashes with message or warning.
now i have removed java plugins and working. Iam using Mozilla Firefox 1.5.0.12.
what could be the possible error?

Read the error message? Also, why are you using such an outdated version of Firefox?

try this screenshot

see
tnx

Spell out your words. And what was that screenshot supposed to do/fix for the OP??

You do realize that just changing your LQ name, and still continuing to post bad advice/questions, will get you ANOTHER bad reputation on this name too, don't you?

adenial,

Well, this post of mine is not related to Java installation but in fact I was curious to know what you are trying to achieve !

Previously you tried to install and learn C,
Then you tried to install Python,
Now you are trying to install Java,

If you are doing all this for someone else, then I have no issues but if you are doing this for yourself, then I doubt that you'll soon become - jack of all and master of none !

Programming languages are not some kind of software which you will install and then test whether it is working properly and then move on to another.

I suggest that you first read up on all programming languages and then decide which one satisfies your need.

Other people following the thread can check OP's thread creation history, if desired, WRT this post of mine.
