SOE - “Failed to construct instance of service xyz"

Question

I created 2 soe projects that are almost identical in structure and code.  I deployed them into my ArcGIS Server.  One of them works fine, but for the 2nd one,  I got  “Failed to construct instance of service xyz. ClassFactory cannot supply requested class."  Any idea for fixing this bug?   Thanks.

Got my problem solved.  The problem was due to the conflict of 2 SOEs that have the same Guid ID and/or Package Id defined inthe AssemblyInfo.cs.  When I built the 2nd one, the 2nd one was copied from the 1st one + needed modification.  Thanks for your review and response.

if your soe is developed with .net and you use ags 10.1 or superior:  how is it compiled in build target ? Any CPU or x86 ?

Since you haven't included code, or mentioned what language you were using, or even the version of ArcGIS, I doubt there's much we can do to help.

I can say that this error is consistent with a failure to include a necessary jarfile in your SOE zipfile when using ArcObjects Java.  If this doesn't pertain to your situation, you'll need to go about things the old-fashioned way, stripping the app down to dummy code, then adding pieces back in until it breaks.
