I could swear when I first installed jdk 1.5 in my new machine (Vista
Ultimate) about three months ago, I put path to 'bin' dir in java
installation in 'path' Windows env variable, and made sure I was able to
both compile and run classes; however, when I tried to compile or run a
class today, I got in trouble....

when I try to compile a .java file I get this error:

  'javac' is not recognized as an internal or external command,
operable program or batch file.

when I try to run a class I get told

   Error: could not open `C:\Program
Files\Java\jre1.5.0_12\lib\i386\jvm.cfg'

this is path to dir 'bin' in my java installation:

   C:\Java\jdk1.5.0_12\jre\bin;

so put this again in path, then restarted machine... but I still get
same errors when try to compile or run classes..

I'm going to pretend there's an environment variable

JAVA_HOME=C:/Java/jdk1.5.0_12

BTW, there's a big security hole in jdk1.5.0_12. You should upgrade to
jdk1.5.0_13 right away.

The compiler, javac.exe, isn't in %JAVA_HOME%/jre/bin/, what you put in your
PATH, it's in %JAVA_HOME%/bin/, not yet in your PATH.

Have you any idea why your execution of java.exe was trying to open
"C:/Program Files/Java/jre1.5.0_12/lib/i386/jvm.cfg"? Does that file exist?
Does even its directory?

Why is that path through "C:/Program Files/" when your JAVA_HOME isn't?
