I don't think OAS 10.1.2.0.2 was ever certified with Windows - at least it is not listed in the [url http://www.oracle.com/technetwork/middleware/ias/downloads/as-certification-r2-101202-095871.html]certification matrix. Given the fact that Oracle doesn't provide error correction support anymore for 10g, it might be better to use 11g. You can install Oracle Forms 11g (11.1.2) for which you indeed need WebLogic Server.
Yesterday I tried downloading weblogic 11g, but after unzipping I got only 1GB "wls1036_generic.jar" file, I have no idea how to intall it.
I followed the following doc:
Can you please send me the download link as its really very confusing and the proper file name to download.
