Before I do this I feel it is wise for me to ask ...

Is there anything about Seamonkey 1.1.13 (I did the upgrade from the stock 1.1.11) in a Puppy 4.11-Normal ext3 formatted Frugal install on a laptop that might cause these instructions to not apply (or need to be modified), please?

I always seem to have one or more variables unaccounted for which send(s) me off into an open-loop of confusion ... Rolling Eyes

Don't follow the above procedure, it is out of date. Instead follow the instructions below.

How to install Java Version 6 Update 11 on Puppy 4.11 for Seamonkey, as of December 18 2008. This also makes JavaScript available to Open Office.

1. Open ROX-Filer, up-arrow, usr, and see if folder /usr/java exists. If it doesn't create it:
Code:
mkdir /usr/java


2. Surf to www.sun.com and click the "Java" icon under the "Downloads" bar. When the "Java" button enlarges click "Download".
This takes me to http://www.java.com/en/download/index.jsp.

3. Click the "Free Java Download" button.

4. In the "Linux (self-extracting file) filesize: 19.23 MB" row, left-click "Linux (self-extracting file)" then "Save it to disk" and save it to /usr/java. On my 512 mbps ADSL connection the download, monitored by Download Manager, takes about 9 minutes.

5. Open in ROX-Filer /usr/java and right-click the icon of jre-6u11-linux-i586.bin, File 'jre-6u11-linux-i586.bin', slide mouse to right onto submenu, left-click on Permissions, left-click Yes to change permissions and make executeable.

6. Right-click-in-whitespace in the /usr/java ROX-Filer window, Window-->Terminal here.
Execute the installer:
Code:
./jre-6u11-linux-i586.bin


7. You will now see the License Agreement. Keep pressing Enter (or R) until you see
Do you agree to the above license terms? [yes or no]
Type "yes" (without quotes) then press Enter.
The binary unpacks to a subdir /usr/java/jre1.6.0_11

8. Issue
Code:
cd /usr/lib/seamonkey/plugins
rm libjavaplugin_oji.so
ln -s /usr/java/jre1.6.0_11/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so
cd /usr/lib/mozilla/plugins
rm libjavaplugin_oji.so
ln -s /usr/java/jre1.6.0_11/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so
cd /root/.mozilla/plugins/java
rm libjavaplugin_oji.so
ln -s /usr/java/jre1.6.0_11/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so


(actually, I'm not sure if all three of the above are required. Does anyone know which one(s) is/are necessary?)

9. In Seamonkey, Edit-->Preferences-->Advanced (click on the +)-->Scripts and Plugins
Check Enable JavaScript for Navigator and for Mail & Newsgroups,
click Advanced (the word Advanced) and check Enable Java.
Close Seamonkey.
Reboot the computer.

10. Restart Seamonkey.
Surf to www.sun.com, Java under Downloads, "Download", "Do I Have Java?", and you should see the
"Congratulations!
You have the recommended Java installed (Version 6 Update 11)."
notification.

11. Done.

Thanks, SitHeelSpeak, for the very detailed HOWTO for installing Java. Unfortunately, I ran into the following error while executing the installer (step 6):
Code:
 inflating: jre-6u11-linux-i586.rpm 
rpm: invalid option -- v
BusyBox v1.8.2 (2007-11-30 09:20:42 GMT-8) multi-call binary

Usage: rpm -i -q[ildc]p package.rpm

Manipulate RPM packages

Options:
        -i      Install package
        -q      Query package
        -p      Query uninstalled package
        -i      Show information
        -l      List contents
        -d      List documents
        -c      List config files

 
Done.

So a .rpm file is being created, but the -v option is not recognized by puppy's 'rpm' command. I suing the rpm command manually, but had the following error:
Code:

sh-3.00# mkdir /usr/java
sh-3.00# rpm -i jre-6u11-linux-i586.rpm
rpm: cannot make dir ./etc: File exists
rpm: cannot make dir ./etc/.java: File exists
rpm: cannot make dir ./etc/.java/.systemPrefs: File exists
rpm: cannot make dir ./usr: File exists
rpm: cannot make dir ./usr/java: File exists
95127 blocks
sh-3.00# /usr/java/jre1.6.0_11/bin/java
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

so there's something going wrong with the installation. Could the problem be with Puppy's rpm command? I would appreciate any help in this regard, since Java is very important for me.
Cheers,
NM

You don't want the 18.6 MB .rpm file, instead you want the 19.23 MB self-extracting (.bin) file immediately underneath the .rpm file. I erroneously wrote it was 19.18 MB in my instructions above. Corrected.

The file on Sun's site changed. I had to modify the code from:
Code:
ln -s /usr/java/jre1.6.0_11/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so

to:
Code:
ln -s /usr/java/jre1.6.0_12/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so

For Firefox 3.03, after executing the installer, the code I used was:

Code:
cd /usr/lib/firefox/plugins
ln -s /usr/java/jre1.6.0_12/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so


Then I enabled Java in the Firefox Toolbar: Edit>Preferences>Content.

OK this is more of an FYI for me - just so I've got it written down somewhere.

/opt/java/jre1.6.0_20/lib/i386/libnpjp2.so

is the file that needs symlinking to

/usr/lib/mozilla/plugins/

Subject description: symlinks for Java on Firefox 3.6.3		  
Even Sun's Java site was unaware of the correct linking.
I found that (2) symlinks into Firefox plugins are now necessary.

Make symbolic links into /lib/firefox/plugins from:
/usr/java/jre1.6.0_20/plugin/i386/ns7/libjavaplugin_oji.so
AND
/usr/java/jre1.6.0_20/lib/i386/libnpjp2.so

Check that the Java plugin loaded in Firefox at: about:plugins

For FireFox:

AND
/usr/java/jre1.6.0_20/lib/i386/libnpjp2.so


that's right.
small correction: "Make symbolic links into usr/lib/firefox/plugins...."

Little bit off-topic Rolling Eyes .
Script for installation of the -=jre-6u23-linux-i586.bin=-
Quote:

Install_JRE-6u23.sh
Code:

Subject description: Response to my last post		  
I followed ROX back through /usr/local/bin/jre1.6.0_02/plugin/i386/ns7/libjavaplugin_oji.so and manually changed the link to /usr/lib/mozilla/plugins/libjavaplugins_oji.so where the faulty symbolic link was. this changed the icon to look like the others so i assume its working now, but when i asked java if it was installed it still said "error." the run action for this newly changed symbolic link is "$@" and i dont know if that is how it should be, its just what was made.

help!

Subject description: Another Update		  
In the SeaMonkey browser i clicked help>about plugins and it lists "Java(TM) Plug-in 1.6.0_26-b03" at the very top, and it says it is completely enabled. however the Java website still claims that java is not working properly, and the site that i need java for is not loading, even though the bar at the bottom says "done"

why?!

thank you

Go here and get the linux self extracting binary. And follow the instructions to install and run the self extractor.

http://www.java.com/en/download/help/linux_install.xml

Ok firsly locate your firefox/plugins DIR, and the java lib directory, my java was in /usr/java/jre1.6.0_29/lib/i386/.


if u are upgrading java remove the old symbolic link first.
To remove old symbolic link:
type cd <Firefox installation directory>/plugins
rm libjavaplugin_oji.so


Then the most important part is linking the java executable to the firefox plugin directory. My plugins DIR is at /usr/lib/firefox/plugins/ . You may have to google it or search for the directory if u installed firefox a different way. Just open up two instances of ROXfiler drag across the file to link and select symlink in RoXfiler.

I installed puppy with the pre-installed seamonkey and still found linking the same file to the mozilla plugins folder worked.
RECAP:
ln -s /usr/bin/jre1.6.0-29/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

CORRECT ME IF THATS WRONG
