I've got a new 64-bit laptop and have installed STS 64-bit and Java 64-bit. I'm trying to create an ODBC connection to a 32-bi Microsoft database; however the default Admin tools don't provide a driver for access. After googling around, I saw that there's an admin tool for creating 32-bit drivers located in C:\Windows\SysWOW64\odbcad32.exe. However, an ODBC connection created from that that gives me an error message indicating an architecture mismatch when I run the program:
"[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application"
I think it's because the 64-bit Java is trying to use the 32-bit driver. To get around the problem, I tried to put the argument "-D32" in the VM arguments, but got the same result.
I'm thinking of uninstalling STS and Java and replacing them with the 32 bit versions. Is there a better solution?
To load a 32-bit native library you need to have a 32-bit JVM.
You don't need to uninstall Java, you can have as many version installed as you like.
You can use your 64-bit JVM to talk to a 32-bit JVM which loads your driver, but this may be more complicated than you need.
