it's not the first time I have this error, so I am posting the problem and the fix if anyone is interested...

after upgrade of 4.1.7 MR1 to MR3. MDS service fail to start

I have the following error:

Event Type: Error

.


my last upgrade to MR1 did the same thing


here was the real problem:

I had the following:
C:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\bin\bmds.exe" -s jvmpath="" -XX:+DisableExplicitGC -Xss128K -Xmx768M -Xms128M classpathdir="C:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\classpath\\" wrkdir="C:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\Servers\mail\\" webserverdir="C:\Program Files\Research In Motion\BlackBerry Enterprise Server\MDS\webserver\\" -rbes "SRVAPP_MDS-CS_3"

into HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BlackBerry MDS Connection Service\ImagePath

the error is the jvmpath="" it should point to something !! In my case I was able to fix it with the following: jvmpath="C:\Program Files\Java\jre1.6.0_07\bin\client\jvm.dll"

I hope it will help anyone having the same issue I had !!

thanks
