PRIMECLUSTER Web-Based Admin View Operation Guide

3.1.3.2 Required for the Web Browser Environment

The supported Java Plug-in versions are clarified in "Prerequisite client environment". Java Plug-in 1.2.2, which Sun Microsystems provides for free, may come with some operation management product packages.

Follow the setup method described in "Setting up Java Plug-in."

Setting up Java Plug-in

PC client

1. Check if Java Plug-in is installed.

   Start [Add or delete Application], and then check if the following Java Plug-in is installed, it is not necessary to install.

   • Java 2 Runtime Environment Standard Edition v1.3.1
   • Java 2 Runtime Environment Standard Edition v1.4.2
2. Install Java Plug-in.

   Execute the following Java Plug-in installer in a CD-ROM.

   • For Java 2 Runtime Environment Standard Edition v1.3.1

     <CDROM drive name>: \plugins\ win\j2re_1_3_1-<version>-win-i.exe

   • For Java 2 Runtime Environment Standard Edition v1.4.2

     <CDROM drive name>: \plugins \win\j2re-1_4_2_<version>-windows-i586-p.exe

   Replace < version > with the file version number on CD-ROM.

   Install following the procedure displayed on the screen.

This completes the setup.

Solaris OS

The setup procedure varies depending on the version of Java Plug-in as follows;

Java(TM) 2 Runtime Environment, Standard Edition Version 1.3.1

1. Copy Java(TM) 2 Runtime Environment, Standard Edition Version 1.3.1 for Solaris OS to the working directory from CD-ROM.

   Set up CD-ROM on the CD-ROM device.

   # cd <CDROM-mountpoint>/plugins/solaris/sparc

   Normally, <CDROM-mountpoint> will be /cdrom/cdrom0

   When the working directory is /var/tmp:

   # cp <CDROM-mountpoint>/plugins/solaris/sparc/j2re-1_3_1_<version>-solsparc.sh /var/tmp

   Replace < version > with the file version number on CD-ROM.

2. Make sure that the execute permissions are set on the self-extracting binary.

   # chmod +x j2re-1_3_1_<version>-solsparc.sh

3. Move directory to the location where the files should be installed.

   # cd <Installed directory>

4. Run the self-extracting binary.

   A directory called j2re1_3_1_<version> is created in the current directory. This directory can be renamed at user's discretion after installation.

5. Set up the environment variable

   Execute the following command to set the environment variable to the shell variable:

   [For C shell]

   # setenv NPX_PLUGIN_PATH <Java Plug-in path>

   [For shell and Kornshell]

   # NPX_PLUGIN_PATH=<Java Plug-in path>

   # export NPX_PLUGIN_PATH

   <Java Plug-in path> is designated the following directory containing the javaplugin.so file.

   <Installed directory>/j2re1_3_1_<version>/plugin/sparc/ns4

   Example: When <Installed directory> is /var/tmp

   <Java Plug-in path>=/var/tmp/j2re1_3_1_<version>/plugin/sparc/ns4

6. Start your Netscape browser, or restart it if it is already activated.
7. Restart your browser again. The browser needs to be restarted twice to avoid the Netscape problem.

Java(TM) 2 Runtime Environment, Standard Edition Version 1.4.2

1. Copy Java(TM) 2 Runtime Environment, Standard Edition Version 1.4.2 for Solaris OS to the working directory from CD-ROM.

   Set up CD-ROM on the CD-ROM device.

   # cd <CDROM-mountpoint>/plugins/solaris/sparc

   Normally, <CDROM-mountpoint> will be /cdrom/cdrom0

   When the working directory is /var/tmp:

   # cp <CDROM-mountpoint>/plugins/solaris/sparc/j2re-1_4_2_<version>-solsparc.sh /var/tmp

   Replace < version > with the file version number on CD-ROM.

2. Make sure that the execute permissions are set on the self-extracting binary.

   # chmod +x j2re-1_4_2_<version>-solsparc.sh

3. Move directory to the location where the files should be installed.

   # cd <Installed directory>

4. Run the self-extracting binary.

   A directory called j2re1_4_2_<version> is created in the current directory. This directory can be renamed at user's discretion after installation.

5. Set up Java Plug-in
   • For Netscape Communicator 4.72-4.7X

     Execute the following command to set the environment variable to the shell variable:

     [For C shell]

     # setenv NPX_PLUGIN_PATH <Java Plug-in path>

     [For shell and Kornshell]

     # NPX_PLUGIN_PATH=<Java Plug-in path>

     # export NPX_PLUGIN_PATH

     <Java Plug-in path> is designated the following directory containing the javaplugin.so file.

     <Installed directory>/j2re1.4.2_<version>/plugin/sparc/ns4

     ex:For <Installed directory> is /var/tmp

     <Java Plug-in path> : /var/tmp/j2re1.4.2_<version>/plugin/sparc/ns4

   • For Netscape7.X

     Create symbolic link from a library file.

     # cd <Netscape7_Installed directory >/Plugins

     # ln -s <Java Plug-in path>/libjavaplugin_oji.so .

     <Java Plug-in path> is designated the following directory containing the javaplugin.so file.

     <Installed directory >/j2re1.4.2_<version>/plugin/sparc/ns610

     ex: For <Installed directory> is /var/tmp

     <Java Plug-in path> : /var/tmp/j2re1.4.2_<version>/plugin/sparc/ns610

   • For Mozilla Web browser(Solaris10 OS)

     Create symbolic link from a library file.

     # cd <Mozilla Web browser_Installed directory >/Plugins

     Normally, <Mozilla Web browser_Installed directory > should be /usr/sfw/lib/moziila.

     # ln -s <Java Plug-in path>/libjavaplugin_oji.so .

     <Java Plug-in path> is designated the following directory containing the javaplugin.so file.

     <Installed directory >/j2re1.4.2_<version>/plugin/sparc/ns610

     ex: For <Installed directory> is /var/tmp

     <Java Plug-in path> : /var/tmp/j2re1.4.2_<version>/plugin/sparc/ns610

6. Start your Netscape browser, or restart it if it is already activated.

   It is restart Netscape Communicator 4.72-4.7X.

5. Set up Java Plug-in
   • When a user logs in with system administrator's access privileges.

     Create symbolic link in one of the following directories from a library file /opt/IBMJava2-131/jre/bin/javaplugin.so.

     /usr/lib/netscape/plugins -Gives all users privileges to use Java Plug-in

     $HOME/.netscape/plugins - Gives users with root privileges to use Java Plug-in

   • When a user logs in without system administrator's access privileges
     1. If the Plugins directory is not present under the /$HOME/.netscape directory, create this directory.
     2. Create symbolic link to the /$HOME/.netscape/plugins directory from the library file /opt/IBMJava2-131/jre/bin/javaplugin.so.

   

   • If Netscape is activated after linking to the netscape/plugins directory from the javaplugin.so file, Netscape is exited out. When it is started from the command line, the Bus error message appears. A user can ignore the error message output when Netscape is started next time because Netscape does not detect it.
   • When using RedHat, execute the following command as the font server can detect the Java True Type font. This should be done with system administrator's access privileges.

     # /usr/sbin/chkfontpath --add /opt/IBMJava2-131/jre/lib/fonts

6. Start the Netscape browser from your terminal. If it's activated, restart the browser.
