There is an mkmf.log file under C:\ruby\lib\ruby\gems\1.8\gems\rjb-1.1.3\ext that says :
have_header: checking for jni.h... -------------------- no

Problem is JAVA_HOME is installed and this is what it says : C:\ruby\letter4sure>echo %JAVA_HOME% C:\Program Files\Java\jdk1.6.0_06
When I walk through extraconf.rb I see that it can see jni.h so what is wrong here?

I do have admin permissions this is what I found in gem_make.out ;

Also I stepped through extraconf.rb by renaming it and putting put statements in it and it can access the jni.h file in the jdk but apparently its failing jni.h check here...
Yes it is a good installation. I also installed jdk 1.5 and jni.h is indeed located there.

That is precisely what I have been using along with the readme file in rjb.

I will write up the issues I encountered and post them on some blog to help out the others.

That's what I thought until I got pissed off with setting paths and crap like that on different machines.
