Java doesnt work in Opera

I just installed java jdk 1.5.0 rc for the amd64. everything was going fine. I started up opera, and Java applets wouldnt load. I checked and java is working fine, i can get java working in konqueror, but opera doesnt recognize the installed path's.

I went into the config and saw that no path was set to the java install. I set them to /opt/sun-jdk-1.5.0_rc1/bin/ where the java executables are located. I hit the "validate path" button, and it tells me that it isnt a valid location. I try looking around for a bit until i find that the path /opt/sun-jdk-1.5.0_rc1/jre/lib/amd64/ is valid. this folder contains the lib*.so files (such as libjava.so), but no executables. I figure whatever, It says its a valid folder, so I save the changes and restart opera. It says java is enabled and I go to load an applet, and the applet fails to load and right after i check again, and suddenly it says java is not enabled.

Here is the output of opera -debugjava:

My opera version is 7.54 final. I also had blackdown java installed before sun java, and opera didnt support java then either.

spaceturtle:

1. what does locate libjava.so display?

2. what does env | grep JAVA display?

On my system the answers are:

1. /opt/blackdown-jdk-1.4.1/jre/lib/i386/libjava.so

2. JAVAC=/opt/blackdown-jdk-1.4.1/bin/javac
JAVA_HOME=/opt/blackdown-jdk-1.4.1

The library libawt.so should be in the same directory as libjava.so

java works on 7.54 (static .1 and shared .5). java works in 7.60tp1
(shared .5 only).

Note1: the easiest way to test java under opera is to start opera and
then enter alt t a j -- if the java console comes up then java
'should' work.

Note2: I never use emerge to install opera -- alway download the file
myself in install it (./install.sh) with a prefix of /usr/local

Okay Space Turtle, should be a pretty simple fix.

Either:

1. Start Opera and go to the preferences (alt p); select 'Multimedia' and in the field 'Java path' enter the following: /opt/sun-jdk-1.5.0_rc1/jre/lib/amd64/

Stop Opera and restart it from the command line:

opera --debugjava &

Does anything change? Test it via alt t a j.

Or

2. Stop opera. Invoke your favorite editor on the file ~/.opera/javapath.txt. If the file doesn't exist, create it and put /opt/sun-jdk-1.5.0_rc1/jre/lib/amd64/ in it. Then start Opera and see if alt t s j works.

Opera's not finding your java (see the code in the Opera script). They don't look for amd64 in the path, the default is i386.

I would not recommend Opera 7.60tp -- plugins are a mess. Stick with 7.54.

My opera java path was already set to /opt/sun-jdk-1.5.0_rc1/jre/lib/amd64/. If I press the validate path button in opera, it tells me that the path is valid and accepts it. I edited the file javapath.txt and /opt/sun-jdk-1.5.0_rc1/jre/lib/amd64/ was already in the file. Either way the java console still does not open and I still so not have java support. Here is the output of opera --javadebug &:
