Problem with getting an SOE to work ( Dynamic Segmentation Utility SOE Rest )

[TracyArchibald]

I'm trying to get this SOE working on my server.
http://www.arcgis.com/home/item.html?id=e3bfa7c991e34aa8872c937ca9169507

I've managed to load it into the Site->Extentions without any problems.  But when we go to publish a service with the capability enabled, we get the following error:

service failed to start
Secured.road_routes.MapServer:
SERVER2.myurl
ClassFactory cannot supply requested class

What class could it be looking for and what do I need to do to make it work?  I've looked through the documenation and can't see anything that sticks out.

I don't have a separate project.  I'm trying to get it working with the sample data first.  And by "working", I mean "get the capability to turn on".

here is the rest URL for the sample data I'm using
http://arcservices.countygp.ab.ca/arcgis/rest/services/TestData2/MapServer

When I go to turn on the "Dynamic Segmentation Utility" Capability in ArcGIS Server Manager, I get :
service failed to start
TestData2.MapServer:
SERVER2.COUNTYGP.AB.CA
ClassFactory cannot supply requested class

I have problem understand this problem because I haven't it. Can you install this soe esri that use similar library arcobjects so I can compare with it if it runs to you?

That one didn't work for me either.  I'm pretty sure the issue is somewhere in the server setup (since we've got such a bare bones setup), but I have no idea where to look.

I've got our server people updating the .NET and few other bits and bobs.  I'll let you know how it goes after that.

[TracyArchibald]

Ok.  So we've updated .net and everything else we can think of.  We also installed 10.1 desktop.  We're still getting the same error.  Any more suggestions?

Also, I can can get a look at the source, I might be able to figure out what I'm missing.  Is that a possibility?

[nicogis]

Have you tried with another soe (for example those in sample esri) ? I haven't this error and I don't know how replicate it in my system.

Hi all

We faced the same problem with this error message:
service failed to start
...
...
ClassFactory cannot supply requested class


The problem was, that we didn't install the ".NET extension support".

Now it works and the map service with the extension can startup.

Thank you Lorenz for your feedback!

Without re-installing arcgis server, is there some way I can confirm that ".NET extension support" has been installed?

Thanks!

In control panel -> Porgram and features -> select arcgis 10.1 sp1 for server -> click uninstall/change -> Modify -> Next  and then see

I have encountered the "ClassFactory cannot supply requested class" error several times over the course of upgrading my 10.0 SOEs to 10.1.

In spite of my best efforts to manually update my existing project files with the new 10.1 build targets and other elements, I ultimately had to just bite the proverbial bullet and create brand new SOE projects using the 10.1 template and port over all my code.

For one particular SOE I actually had to recreate its project from the 10.1 template (SOAP) a second time because of the "ClassFactory cannot supply requested class" error thrown during service startup.
