   can someone please tell me how to install java in Slitaz 3.0
   I prefer using the opera 11.50 browser.

   I have unsuccessfully tried the following as root:
   #tazpkg recharge
   #tazpkg get-install get-java6-jre
   #get-java6-jre

   If java is installed on SliTaz, go to /usr/lib/opera/plugins
   and as root :
   # ln -s /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so

   i am confused. i only know very basics of linux. but i am trying to learn.

   this is what i tried:
   opened pcmanfm as root from xterm. navigated to /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so. copied the file libnpjp2.so. pasted it in /usr/lib/opera/plugins. resatrted opera. java is not working.

   how should i do this?

   Hi jag,
   Sometimes what you tried works,this is the error at the java test site:
   tux@blending:~$ opera <=start program in terminal to read error info
   Didn't find JVM under /usr/lib/opera/plugins
   operapluginwrapper: ../../../../src/plugin/solaris/plugin2/common/JavaVM.c:104: InitializeJVM: Assertion `foundJVM' failed.
   Didn't find JVM under /usr/lib/opera/plugins
   operapluginwrapper: ../../../../src/plugin/solaris/plugin2/common/JavaVM.c:104:
   Delete copy of libnpjp2.so and create a symbolic link:
   Open xterm,become root:
   su <=su or super user click enter key
   password: root <=what you type will not be displayed, click enter key
   root@slitaz:~#cd /usr/lib/opera/plugins <=cd means change directory, click enter
   Next command info: ln is short for link -s switch means symbolic
   root@slitaz:/usr/lib/opera/plugins# ln -s /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so
   Click enter
   root@slitaz:/usr/lib/opera/plugins#ls -la <=ls: list files -l: long a: all
   Click enter <= to verify symlink is correct
   lrwxrwxrwx 1 root root 46 Jun 29 20:24 libnpjp2.so -> /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so

   Restart Opera

   thanks, i was able to get java working after following your steps.
   this is what i did:

   1. logged in terminal as root
   2. root@slitaz:~#cd /usr/lib/opera/plugins
   3. root@slitaz:/usr/lib/opera/plugins# ln -s /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so
   4. root@slitaz:/usr/lib/opera/plugins#ls -la
   5. verified symlink: lrwxrwxrwx 1 root root 46 jun 30 09:26 libnpjp2.s0 -> /usr/lib/java/jre1.6.0_17/lib/i386/libnpjp2.so

   its now running VERSION 6 UPDATE 17. how am i supposed to update this in future? do i need to remove this and install the new one when it becomes available? can i update to the current Version 6 update 26?

   npjp2.so
   ln: libnpjp2.so: File exists
   root@slitazpaola:/usr/lib/opera/plugins# ls -ls
   0 lrwxrwxrwx 1 root root 50 Jul 4 14:40 libnpjp2.so -> /opt/jre/1.6.0_21/usr/java/jre1.6.0.21/libnpjp2.so
   4 -rw-r--r-- 1 root root 137 May 13 06:47 README

   @Paola your symlink /usr/lib/opera/plugins/libnpjp2.so is broken.

   Delete broken link:
   #rm /usr/lib/opera/plugins/libnpjp2.so
   You must find the path to target libnpjp2.so on your java installation :
   #find / -iname libnpjp2.so
   Use the path to libnpjp2.so to create a valid link:
   #ln -s /path/to/libnpjp2.so /usr/lib/opera/plugins/
