Dave,
I understand what you are saying but it appears that I'm a bit confused.

When I installed CF it came with it's own JVM.  This is in the folder called  
C:\CFusionMX\runtime\jre and the CF administrator is pointed to it.  It was 
presumably version 1.4.2_ etc.

Over time I downloaded and updated several JVM's from the Sun website but into 
the C:\Program Files\Java folder.  So, CF was never aware of those updates and 
continued to use the 1.4.2_ version in C:\CFusionMX\runtime\jre.

Now, my JVM on the server is at 1.5.0_06 but my CF Server (C:/CfusionMX folder) 
is at 1.4.2-b28.  The suggestion from Dave C. earlier in the thread was to 
update to the latest 1.4.2 version which I believe is 1.4.2_12.  But if the CF 
Server is not recognizing the 1.5.0_06 version I have installed on the server 
already then a) it won't recognize that I've changed from 1.5 to 1.4.2._12, and 
b) it shouldn't be having a problem with any conflicts caused by version 1.5 
either.

I know it's a lot of number soup but I tried to point the CF java/jvm admin 
page to the folder with the 1.5.0_06 version in C:/Program 
Files/Java/jre1.5.0_06 and then I could not restart CF. Maybe this is what you 
meant in the second paragraph where you noted the heap size/start up problem 
with JVM 1.5??

So, in the end do I need to update the JVM in the C:/CFusionMX folder instead 
of the one in the C:/Program Files/Java folder to the most recent 1.4.2_12 
version???

Thanks so much for your input.  By the way, I'm going to try to arrange to come 
down to D.C. and take the Advanced CF Class that you have there at figleaf.
