Problem Determination

This page describes how to perform problem determination on MQJExplorer and resolutions for some of the most common problems.

General debugging

From the File menu, the View Log entry may be selected. This will pop-up a window containing the Java console log from which errors can be found.

MQSeries Java support not set up

If the MA88 MQSeries Java SupportPac is not installed correctly or the <root>/java/lib directory is not in the search path, an error similar to the following may be seen in the log:

The resolution to this problem is to install MA88 and ensure that <root>/java/lib is in the PATH. Commonly, this is:

C:\Program Files\IBM\MQSeries\Java\lib
