Debugging Dispatch System start-up issues

The following check list goes over the primary causes of Dispatch system launch failures and the solutions to the issues.

1.Correct Java version installed

Dispatch is a web Launched Java application that needs Java to be installed on the local client workstation.

Dispatch will run on Java version 1.5.0 or greater.

To check to see what version of Java is installed on your workstation go into “Control Panel” and click the Java Icon. On the General tab click the About button.

As long as the Java version is 1.5.0 or greater Dispatch will work.

If there is no Java Icon in the Control Panel then you will need to download Java from:

http://java.sun.com/javase/downloads/index.jsp

Select the JRE not the JDK download.

2.

Invalid Java cache files

When you Launch Dispatch and the Java Download screen appears:

At this point the Java files are being downloaded to your workstation, once completed the Java runtime will launch Dispatch. If Dispatch fails to launch or a Java error window appears then clearing your Java cache can correct this problem.

To clear your java cache you must go into Windows Control Panel and click on the Java Icon and on the general tab click on the “Settings” button in the Temporary Internet Files panel.

Click on the Delete files button to erase all temporary Java cache files.

3. Network connectivity

If there are network issues the Java download screen can either timeout or stall. When this condition occurs the Java Web Start window will stay open in a stalled state. If this occurs then try again when the network issues have been resolved or try from another workstation.

4. Local Firewall

Some organizations control what web sites are viewable or accessible. Dispatch runs over the standard web site port so most firewalls will not block it from functioning.
