Are you planning to support latest java release in opera 8 ?

I have 8.0b1 and even though I have added jre 5.0 (1.5), it still uses
older 1.4.2 version

On Linux you can go to Preferences -> Multimedia and set the path to the
Java JRE that Opera uses. Don't remember if this is applicable for the
windows version.

Works great for me in Linux.

On my Linux installation I don't have something like that, but it turns
out to be very easy to get Opera to use a particular Linux. I just
created a file called ~/.opera/javapath.txt and placed the single line:

/usr/java/jdk1.5.0_01/jre/lib/i386/

in it. Done.

As far as remember there was a GUI option to find java installation in
Linux.
In windows, simple combobox allowing to choose from different jvm versions
(as listed in windows registry)
would do.

FYI: If it uses the older version, it's because the Windows registry

Windows? Go to the Control Panel, you'll find a Java Plugin Control
Center, you can use it to choose among installed versions of Java. (Not
certain if Opera follows it, but they should.)

Technically, neither does IE. Yet the plugin contol center still
determines which version of Sun's Java will be used in IE.

1) Uninstall all existing java versions.
2) clean the registry with a proper cleaning tool like regvac.
3) reboot
4) install java 1.5
5) start opera

I did not mean kill the complete registry..
In fact those tools tody it up and kick out unused entries.

Cleaning the registry with a registry cleaning tool is just for the sake
of uninstalling something _completely_. Some uninstallers like to leave
rubbish in the registry and sometimes this rubbish can be a part of the
problem.

Have you tried changing the settings in the Java Control Panel? (Start >

Anyway, it's not recommended you have multiple Java runtimes installed.
You should uninstall all of them, then re-install just the one you want.

Generally you're right, but I developing applets is part of my job, so
it's often necessary to have two java versions.
And for a work computer, reinstalling everything is not the best solution.

Sometimes I think that Java support is not top priority for Opera right
know, so it's native java handling may be a bit
behind Sun plug-in.

For example - Sun applet catching seems to be a better solution than
catching applets in browser cache.

May be this is the right tool for:

It's in german, but I think you can undestand how to use it anyway.
With this tool it's possible to use any installed Opera with any of

Several behaviours/problems I have observed:

Sun's plug-in has jar cache separated from browser cache.
applet jars are only downloaded if they are newer than cached, but this is
verified EACH TIME.
This way you always have the latest version and do not have to worry that
your applet will be deleted
from cache only because it is older than specified in "cache other"
setting or because your browser cache is full.
(For me this is works similar to jar memory in mobile phones)

Furthermore, if your applet is in browser cache (like in opera) event
though newer version is on the server
you may still get the version from cache.

In several cases, java in Opera behaves differently than plug-in, what
causes compatibility problems
(need to test applets on two platforms).
For example, when I try to print from applet, Sun plug-in asks for
permission, while
Opera silently refuses - unless you check java console:
Exception in thread "AWT-EventQueue-1"
java.security.AccessControlException: access denied
(java.lang.RuntimePermission queuePrintJob)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPrintJobAccess(Unknown Source)
at java.awt.print.PrinterJob.getPrinterJob(Unknown Source)
...

The last thing - after I installed Java 1.5 next to 1.4.2, browsers
using plug-in automatically switched to newer version,
while Opera stayed with 1.4.2 (it seems version info is stored somewhere
in opera.ini file)

Being concerned about this, I searched, and I could find no version info
for Java in any Opera .ini files.
Check you registry.

As explained, Opera scans the Windows registry, and uses the version

If there are multiple versions installed, will Opera's scan stop on the
first one it finds? And could this be the earlier version?

I solved my problems with Java by completely uninstatlling all versions
and then installing only the latest version.

The Windows Registry tells Opera what the active Java version is. That's
all there it to it. I don't know how the various Sun JRE installers store
or fail to store that information properly in the Windows Registry.

Except it is a known fact that with some versions of Java if you installed
new then uninstalled old, the uninstall removed all the registry settings
for the new version. That was supposedly fixed at some point though.
