Title: How do you enable Java in Opera 9.64?
Post by: combo3 on December 16, 2009, 02:45:22 PM

I can't get the "java enabled" checkbox to persist after browser restart.

Steps taken:

1. Downloaded Linux (self-extracting file) (http://java.com/en/download/manual.jsp?locale=en&host=java.com:80#lin) - jre-6u17-linux-i586.bin to /mnt/hdb1/java (tc:staff 755)

2. Follwed extraction instructions (http://java.com/en/download/help/5000010500.xml#selfextracting).

3. Followed Enabling Java in Opera for Linux (http://www.opera.com/support/kb/view/459/)

 - changed java path to /mnt/hdb1/java/jre1.6.0_17/lib/i386
 - validated path and clicked [ok] [ok] [ok]

4. Restarted browser and tried test applet (http://www.opera.com/media/applets/clock/) - nothing.

5. Help > About Opera

 Java  - No Java Runtime Environment installed

6. Tools > Quick Preferences > Java Enabled (unchecked)

Yet -  cat /home/tc/.opera/opera6.ini shows:

[Java]
Enabled=1

7. Repeated steps 3 - 6 again with same results.

8. Started Opera from terminal:

tc@box:~ $ opera
ERROR: ld.so: object 'libjvm.so' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object 'libawt.so' from LD_PRELOAD cannot be preloaded: ignored.

9. From a second terminal:

tc@box:~ $ find / -iname libawt.so 2>/dev/null   
/mnt/hdb1/java/jre1.6.0_17/lib/i386/libawt.so

Seems to be in the path
 
tc@box:~ $ find / -iname libjvm.so 2>/dev/null
/mnt/hdb1/java/jre1.6.0_17/lib/i386/server/libjvm.so
/mnt/hdb1/java/jre1.6.0_17/lib/i386/client/libjvm.so

10. Created symlink:

sudo ln -s /mnt/hdb1/java/jre1.6.0_17/lib/i386/server/libjvm.so /mnt/hdb1/java/jre1.6.0_17/lib/i386/libjvm.so

11. Repeated step 3 and received new error message in first terminal:

opera: libjava.so: cannot open shared object file: No such file or directory

tc@box:~ $ find / -iname libjava.so 2>/dev/null   
/mnt/hdb1/java/jre1.6.0_17/lib/i386/libjava.so

This also seems to be in the path

Google search turns up similar problems, but no viable solutions.

(Note: The Mozilla plugin works as advertised, but I'd prefer to get this working in Opera.)

It appears that Java 1.6 does not work. I used 1.5.0_21 and it worked fine.
