Thanks to langel and fitzsim's help, I've created a gcjwebplugin-test package for x86 FC5. It's built from GNU Classpath and jamvm cvs HEAD sources. The source RPM just contains a script for checking out the sources and building them. The binary RPM includes all the sources (installed under /usr/share/gcjwebplugin-test). To try it out, simple create a file called /etc/yum.repos.d/gcjwebplugin-test.repo with the following contents: [gcjwebplugin-test] name=Experimental gcjwebplugin repository baseurl=http://people.redhat.com/green/gcjwebplugin-test/fedora/$releasever/$basearch enabled=1 gpgcheck=0 Then "yum install gcjwebplugin-test". I don't know what this will do if you have Sun's plugin installed as well (I don't). Also, this version of the plugin includes Lillian's whitelist trick, so it will only load applets you specifically say are "OK". Please report any applet bugs to the GNU Classpath bugzilla repository.. http://gcc.gnu.org/bugzilla. Thanks, AG
