java problem with browser

I noticed again that the java applet were not working correctly in firefox. I looked for the solution since I knew I once had solved the problem. But I could not find it easily again. After I tried to start the ControlPanel from the jre, an error occured:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/java/jre1.6.0_03/lib/i386/libdeploy.so: libstdc++.so.5: cannot open shared object file: No such file or directory

I installed the compatibility libraries ( after calling yum provides libstdc++.so.5. Once installed, java applets were working just fine.
