Troubleshooting Java on Windows

In most cases 32-bit Java is required on Windows, these days most machines are 64-bit and users generally use 64-bit browsers this leads to 64-bit Java installed on most system since users arrive to java.com using 64 bit browsers.

To verify that you have 32-bit java installed you will need to open the 32-bit command prompt.

Instructions: 1. Click Start. 2. Type %windir%\SysWoW64\cmd.exe in Start Search box.

Once the command prompt is up type: java -version

You should get the version of the installed 32-bit java.

Webviewer is black or has Red X

This happens because Java now requires the same jars for applets as it does for webstart. All 360Works plugins had to be redeployed to comply with this. The solution is to use the latest version of the all 360Works plugins.

Unsupported class version

This can happen on Leopard if /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK is symlinked to 1.6 instead of 1.5 as on most systems. This is a problem because Java 6 on Leopard is 64-bit and FileMaker is a 32-bit application. Update all 360Works plugins to the latest version.
