set the Java environment of Netscape in Linux

Firefox 1.0


Since Firefox does not include any built-in Java, you have to install JRE manually.

1. Download a JRE (1.5 or higher version) from Sun's Java site and install it by following its installation instruction.


2. Go to the <FIREFOX_HOME>/plugin directory (<FIREFOX_HOME> is the directory where Firefox is installed) and create a symbolic link to Java Plugin.




Code:

ln -s <JRE_HOME>/plugin/i386/ns7/libjavaplugin_oji.so .




Where <JRE_HOME> is the home directory of the Java Runtime Environment. (E.g.: /usr/java/jre.1.5.0_02)


3. Restart the browser.

Netscape 7.1 / Mozilla 1.4 (and above version)


These browsers do not include any Java. They require Java Runtime Environment (JRE) 1.4.2 or later.

1. If you have not got any JRE on your machine or the installed one is not the required version, then download a JRE from the Sun's Java site and install it.


2. Search the home directory of the browser. Most of Linux distribution include Mozilla. Generally, it is located in the /usr/lib/mozilla-X.Y.Z directory (where X.Y.Z is the version number of the browser. E.g.: /usr/lib/mozilla-1.2.1).


3. Go to the plugin subdirectory of the browser.


4. Check your permissions for this directory. Generally, only the administrator (root account) has got a write permission for this directory.


5. To add Java to the plug-ins list of the browser, you should create a symbolic link to the JRE included Java plugin-in.

Code:

ln -s <JRE_HOME>/plugin/i386/ns610-gcc32/libjavaplugin_oji.so .

Where <JRE_HOME> is the home directory of the JRE. E.g.: /usr/java/j2sdk1.4.2/jre


6. Restart the browser (be sure you have closed each running Netscape / Mozilla applications). Then select Help / About Plug-ins menu item from the menubar to check the available plug-ins in the plug-ins list. If you do not find the required Java plug-in there, exit from the application and restart it again.

Netscape 6 - 7.02 /Mozilla (1.3.1 and below versions)


Netscape 6 and Netscape 7.0 contain a built-in Java to run applets. If your browser does not include any Java or you would like set a new default, do the following.

1. Perform steps 1 to 4 in the previous section.


2. Create a symbolic link:




Code:

ln -s <JRE_HOME>/plugin/i386/ns600/libjavaplugin_oji.so .




Where <JRE_HOME> is the home directory of the required JRE.


3. See the 6th step in the previous section.

In a few cases, the browser can not recognize Java plug-in although you have creaed the libjavaplugin_oji.so symbolic link in the plugin directory. In that case, add a new symbolic link (libjavaplugin_oji140.so) to the same directory. Then restart the browser.
