IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Remove the Java plug-in on Windows
When either the IBM JRE or the Oracle JRE is installed on Windows, the Java installer automatically registers the associated Java plug-in with both Internet Explorer and Firefox. Plug-in registration conflicts sometimes occur on Windows when both JREs are installed.
The symptoms usually involve one of the following messages being displayed when you launch the Tivoli Enterprise Portal client:
“Java Plug-in detected JRE collision”or
“Applet(s) in this HTML page requires a version of java different from the one the browser is currently using. In order to run the applet(s) in this HTML page, a new browser session is required. Press ‘Yes” to start a new browser session.The solution is to de-register the plug-in.
To de-register the Java plug-in take the following steps:
- Launch the IBM Control Panel for Java or the Oracle Java Control Panel from the Windows Control Panel folder.
- Select the Advanced tab.
- Expand the branch entitled APPLET tag support.
There should be two entries, one for "Internet Explorer" and one for "Mozilla and Netscape". Normally, after installation of Java, both of these boxes will be checked, meaning that the associated Java plug-ins for those browsers have been registered. Figure 1 shows the IBM Control Panel for Java; the Oracle version is almost identical.
The branch labels found in the Advanced tab may be different depending on whether you are using Java 1.5, 1.6, or 1.7. Figure 1 is specific to Java 1.7. The branch label for Java 1.7 is entitled Default Java for browsers. In addition, the actual labels associated with the browsers listed may differ between 1.5, 1.6, and 1.7. With Java 1.7, the labels are Microsoft Internet Explorer and Mozilla family.

If you encounter problems loading Tivoli Enterprise Portal using Firefox, this is one of the first panels you should look at to ensure that the Java plug-in has indeed been registered. Often, a quick way to resolve any registration problems is to simply remove the check mark (if already on), press Apply, then check the box again, and again press Apply. This action will switch the option off and on so that the plug-in registration is reset and the correct Windows registry entries get re-established.
- Remove the check mark from the box for the browser or browsers you want to unregister.
