[Product_Support]

Issue

  Note: If the error you see is “Error. Click for details” and not a blank window, please refer to the article: WebStation graphics not working after Java updated to Java 7 Update 51.

Product Line

EcoStruxure Building Operation, TAC Vista

Environment

• Java
• Building Operation WebStation

Cause

• Compatibility issues between Java and WebStation in TAC Vista or older Building Operation versions.
• Java applets were historically used for TGML graphics, causing security warnings and browser compatibility problems.
• Transition to HTML5 technology eliminated these issues.

Resolution

For Java-related issues (TAC Vista or SBO 1.5 and earlier)

1. Update Java

   • Install the latest Java version (e.g., 1.7u67).
   • On x64 systems, install both x86 and x64 Java versions.

2. If issue persists, perform clean reinstall:

   • Close all browsers.
   • Uninstall all Java versions.
   • Backup exception.sites file:

     C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment\security\exception.sites
     

   • Delete folder:

     C:\Users\<username>\AppData\LocalLow\Sun
     

   • Reinstall latest Java (both x86 and x64 if applicable).
   • Verify Java installation using Java uninstall applet.
   • Restore exception.sites file to its original location.
