Bingo!!! That solved the reflection error.

You'd either have to link it to a version that does or ILMerge it into the iBatis DLL. It's a pain.

Now my host has sent out an email saying that they’re switching to medium trust in a week. I decided to test this out by setting the trust level to medium in my application, and sure enough, my ibatis calls no longer work. I’ve tried marking the EntrepreneurialTechnologies.DatabaseHelper class (which calls Ibatis) with the AllowPartiallyTrustedCallers attribute and signing it, but to no avail. I still get the security exception. What I’d like to know is if this is something that just cannot be done, if Ibatis is fundamentally incompatible with medium-trust environments, or if there is a way to configure things so that it will run in medium trust. Does anyone have this working currently? If this is something obvious that I am not getting about how medium trust works, please forgive me. I’ve never had to deal with this much before. Any and all guidance is appreciated.
