I tried all the suggestions that Oracle and my tech person mentioned. I uninstalled all versions of java. I re-installed both the 32-bit and 64-bit version with no success. I have tried to uninstall and re-install my browsers with no luck.
javaws.exe is present in the bin directory (next to java.exe) in my Java 6 JRE installation. I've just installed a freshly downloaded version of Java 7, and it contains javaws.exe in the same location. I don't understand why it is missing in your system. However, some security flaws in Java connected to web were reported recently, and some vendors have disabled Java in their browsers. I'd check with your antivirus software to see whether it doesn't prevent you from accessing the javaws.exe; I'd say it's unlikely, but possible.
