PxPages Fail to Load After Installing Java 7 Update 65


Tech Tip: PxPages Fail to Load After Installing Java 7 u65


Date:             Jul 25, 2014
Product:       NiagaraAX Web UI
Revision:      Niagara Ax Releases 3.6u4, 3.7u1 and 3.8R


Oracle has just released Java 7 Update 65 which appears to cause the Niagara web applet to fail to load completely. This issue may affect your customers who accept the default automatic Java upgrade. When attempting to connect to a Niagara station through a web browser using a Wb WebProfile, the web browser halts while loading images on pxPages. Refresh of the browser typically triggers the completion of the page loading.


Updated versions of bajaui, gx, raster and workbench jars have been created that function properly with Java 1.7.0_65. Users will need to update these jar files using the Workbench "Software Manager". Updated files will be available as part of upcoming Niagara 3.6, 3.7 and 3.8 maintenance builds, as well as the downloadable archive described below.

Please make sure you have the latest versions of modules for the base release prior to installing the attached patches.

Niagara Ax patch build, commonly referred to as 3.7.106 consolidated patches, is a required prerequisite for installation of the 3.7.106 version of bajaui.jar, gx.jar, raster.jar and workbench.jar

Download and install bajaui.jar, gx.jar, raster.jar and workbench.jar for 3.6, 3.7 and 3.8 stations. The download is a password protected archive, password=niagara. Follow the instructions below for the version installed. Remember to clear caches on the client workstation after updating!

5. Restart workbench (if same installation as above Supervisor workstation, omit).

6. Open a platform connection to the JACE to be updated.


7. Using the "Software Manager" platform view, select bajaui.jar, gx.jar, raster.jar and workbench.jar.

Clear the various caches associated with the browser.

1. Clear the browser's cache. Clear the temporary internet files, cookies and history.

Each browser is cleared differently. Use the browser's help for information on clearing its cache.

2. Delete all the files in the "wbapplet" cache (Note: <user dir> is the Windows user):

<user dir>\niagara\wbapplet

3. Delete everything in the "Secondary Applet" cache (Note: <user dir> is the Windows user):

Windows 7: <user dir>\AppData\LocalLow\Sun\Java\Deployment\cache
Windows XP: <user dir>\Application data\sun\java\deployment\cache

4. Restart the browser (this also clears the session cookies).

5. Log in.
