OK folks. Here is what I did to get the R java search applet working. Note that this is on 32 bit F8, not 64 bit. Make any appropriate adjustments as required. 1. Remove Iced Tea sudo yum remove java-1.7.0-icedtea-* 2. Go to the java.sun.com web site and secure the appropriate JRE download. In my case, it was: jre-6u3-linux-i586-rpm.bin 3. Set the above to be executable: chmod +x jre-6u3-linux-i586-rpm.bin 4. Run and install the above as root: sudo ./jre-6u3-linux-i586-rpm.bin 5. Create the symlink to the JRE plugin: cd ~/.mozilla/plugins ln -s /usr/java/jre1.6.0_03/plugin/i386/ns7/libjavaplugin_oji.so 6. Be sure that you have no Firefox sessions open. If you do, close them all. 7. In R, type help.start() 8. In the new Firefox session, click on the "Search Engine & Keywords" link 9. Pay attention to the lower left hand corner of the Firefox status line. If all went well, you should see: Applet SearchEngine started indicating that all should be well. Just to check, enter a keyword (eg. 'plot') and hit the search button. HTH. It is working for me here. Cheers, Marc Schwartz
