It's quite ok, but there are "discussion boards" on Google Code. They
are actually mailing lists, hosted on Google Groups, and can be found
on the BlueCove home page and Google Code project page.
They are:

http://groups.google.com/group/bluecove-developers

Are you sure that it's the same JDK version? Because the only time
I've had this error is when I tried to run a class compiled with JDK
1.5 on JDK 1.4.

Visual Studio 2005 Express edition can be downloaded and used for
free. It is what I use.

I sometimes use Eclipse, but mostly just JDK, Ant and Vim. Ant is a
"make" replacement for java. Install ant. Go to the directory with
the BlueCove source. Run "ant jar". This only compiles the java code.

If JNI has been stable between JDK 1.5 and JDK 1.4 then you should
only need to recompile the Java part. Otherwise you have to recompile
both.
