Hi,

Due to a lot of user request I've started working on a port for the
OpenJDK6 IcedTea Java plugin which works with Firefox 3.6. As I never
used the Java plugin and I'm not very experienced in the Java world I
need some help.

Some parts of the port are taken from java/openjdk6 and pkgsrc. The shar
file of the current port is available here:
http://people.freebsd.org/~beat/patches/icedtea6-plugin.shar

I've tested the port on FreeBSD 8.1 amd64 and i386. The plugin was
recognized after creating a symlink in ~/.mozilla/plugins/:
# ln -s /usr/local/lib/netscape/plugins/IcedTeaPlugin.so ~/.mozilla/plugins/

When I tried to watch a Java applet the browser crashed:

Exception in thread "main" java.lang.IllegalAccessError: tried to access
class sun.applet.AppletMessageHandler from class

        at sun.applet.PluginMain.<init>(PluginMain.java:137)
        at sun.applet.PluginMain.main(PluginMain.java:116)

So I copied the content of
www/icedtea6-plugin/work/icedtea6-1.8/liveconnect to
/usr/local/lib/netscape/plugins/ (This step isn't done by the port yet
as I don't know if this is the correct location) set the CLASSPATH
environment variable but it crashed again:

# mv /usr/ports/www/icedtea6-plugin/work/icedtea6-1.8/liveconnect/*
/usr/local/lib/netscape/plugins/
# setenv CLASSPATH /usr/local/lib/netscape/plugins/
# firefox3

        at sun.applet.PluginMain.main(PluginMain.java:116)

Does anyone knows how to fix this problem?

There are also some parts (marked with a comment) in the port makefile
which needs some review or improvement.

Thanks,
Beat
