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.
Download and install bajaui.jar, gx.jar, raster.jar and workbench.jar for 3.6, 3.7 and 3.8 stations. The download JavaUpdate65Patches.zip 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!
Archive password = niagara
