I have an intermittent problem starting WMQ Explorer v6.0.2.1 on Windows XP professional. I am running MQ Explorer nuder a different user ID that I am logged on using the "Run with different credentials" option on the shortcut. I log on using a local account that is part of the mqm/Administrators group.
Most of the time it works, but sometimes I get a message "An error has occurred when creating this view" in the WMQ Navigator pane. I did a search on ibm.com and fonud the reference to http://www-1.ibm.com/support/docview.wss?rs=171&context=SSFKSJ&context=SSWHKB&q1=%22An+error+has+occurred+when+creating+this+view%22&uid=swg21208670&loc=en_US&cs=utf-8&lang=en
This is not an exact match to my problem (I am not uninstalling/reinstalling MQ) but I tried what it suggests and this had no effect. In my eclipse .log file I get the following error:

Has anybody else encountered this? If so did you find a resolution.
Normally I can exit the explorer and restart and it will work (unless I am busy and then it invariably insists on repeating the problem a few times  )

Well, I don't think it's lying to you. I would debug the first error first. The one that says:
java.lang.NullPointerException
at com.ibm.mq.explorer.core.internal.event.DmMonitor.notifyNewListener(DmMonitor.java:1499)

This looks like a bug, you should not be getting any NPE's in the WMQ Explorer code - I'd suggest you raise a PMR  |
