Yes. Running Tomcat 6 as a Windows service... Ok, this is interesting. On a whim, I ran tomcat6w, and when it came up, it appears to using the "C:\Program Files (x86)\Java\jre6\bin\client\jvm.dll", which implies to me that the JVM it's attempting to use is the 32-bit version.
High five, Mr. Kobly.

I searched around and, under C:\Program Files, I found a couple of jvm.dll's. I tried pointing Tomcat to each of them, but the service died with an error code of #1. Not sure what that is, but it occurs to me that I might fix this by simply reinstalling Tomcat and, when it asks for a JRE, I'll point it to the other JVM DLLs and see what it does.

Other native apps. The Java apps are being migrated from a 32-bit environment (WinXP and Java 32-bit + Struts 1.1), and they worked there. I don't want to point to any one thing, since every part of the equation is a newer version of what was there before, but at this point the only things that can't use the connections are the web apps.
But the web apps are the only things that use Java. You don't have standalone Java apps or Java webapps built on a different framework than Struts... The issue is almost certainly a 32-bit JRE trying to access a 64-bit ODBC driver.

I'll buy that, but I'm confused -- I installed 64-bit Java, and when I open a command prompt and do "java -version", it identifies itself as:

   Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
   Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

But I'll see if I have anything on my system that is getting loaded that's 32-bit.

Thanks!
