Add the different methods to unregister the plugin with the Netscape 6 browser to the Unix (Solaris, Linux) install documents. For different versions of the plugin there are different steps to take to unregister the plugin with the browser.

If the user does not unregister the previous version of the plugin they will have problems using the plugin. The plugin will not work, applets will not run, the browser may crash.

1. JRE/Plug-in 1.3 (JRE 1.4.1)
Check the <NS6>/plugins directory for a libjavaplugin_oji.so file, or a similar file name. This file links to the Java Plug-in so file in the jre/plugin/sparc/ns610 directory. Remove this file in the <NS6>/plugins directory.


2. JRE/Plug-in 1.4
a) If you used the Netscape regxpcom command to register the Java Plug-in use
the same command to unregister it.

setenv LD_LIBRARY_PATH <Netscape 6>:$LD_LIBRARY_PATH

If you do not add Netscape to your LD_LIBRARY_PATH you will most likely get an error when you run regxpcom. Something like, Open failed: No such file or directory.

regxpcom -u <absolute path to Java Plug-in libjavaplugin.so file>

Example:
regxpcom -u <JRE>/plugin/sparc/ns610/libjavaplugin_oji140.so

b) Or if you created a link to the Java Plug-in so file, Check the <NS6>/components directory for a libjavaplugin_oji.so file, or a similar file name. This file links to the Java Plug-in so file in the jre/plugin/sparc/ns610 directory. Remove this file in the <NS6>/components directory.

3. Also check if there is a java directory in the Netscape directory. The browser may be using the Java Plug-in that is in that directory. Check the Java version <NS6>/java/bin/java -version. If this is not the Java Plug-in version you want to use follow the above steps to unregister it and then register the version of the Java Plug-in you want to use.
