Java Management Tool FAQ

UNH Enterprise Application users require a secure environment to protect USNH Enterprise data.  To this end, IT will upgrade Configuration Manager users to Java 8 and Internet Explorer (IE) 11 in early January 2016. For users opting out of Configuration Manager, a stand-alone installer will be provided on the USNH Gateway page.

The following represents an anticipated list of questions from our clients.

What is the Java Management Tool (JMT)?

The JMT is a software package which installs multiple Oracle Java Runtime Environments (JRE’s) and management files on the target computer.  If the computer is a member of the UNH Active Directory domain AD then a management agent (Microsoft ConfigMgr) is also placed on the computer to facilitate future JMT updates.

What is the purpose of the JMT?

UNH-IT supports several applications that require a JRE.  Invariably the JRE versions required will differ between these applications. The JMT components allow client computers to use multiple JRE versions, with each application using its required JRE version.

Who can use the JMT?

Anyone with a UNH or GSC computer who uses Enterprise System Java-based applications can use the JMT and receive support from UNH Enterprise Technology Services.  PSU and KSC users should consult with their respective desktop support personnel before installing the JMT.

See the ETS Support Matrix on the USNH Gateway page for a list of Enterprise System applications.    

How can I get the JMT?

The JMT is available on the USNH Gateway page from the Software link under the heading of Availability, Downloads, & Support.  Scroll to (JRE) Java Runtime Environment and click the Install link.

If your computer is already managed by ConfigMgr then you will find the JMT in the ConfigMgr Application Catalog at https://appcat.unh.edu/cmapplicationcatalog.  (AD login required). 

How can I check to see if I already have the JMT or ConfigMgr?

The JMT is a collection of JRE’s and management files, some of which may change with updates.  The best way to determine if Java is being managed is to look for the DeploymentRuleSet.jar file in C:\Windows\Sun\Java\Deployment. 

To determine if ConfigMgr is installed go to Control Panel > All Control panel Items and look for the Configuration Manager applet.  If it exists then the ConfigMgr agent is installed.

Who can I contact if I have problems with the JMT?

If you have problems installing or using the JMT, contact the UNH IT Service Desk at (603) 862-4242 for assistance.
