Running jFlex

Does anyone have any experience running the jFlex??

I have downloaded and installed jFlex, and following the directions changed both my JAVA_HOME path and JFLEX_HOME path to where both files exist. When I try to run jFlex from the command line I receive this error:


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

any help would be great,
Hunter

Are you supposed to add the jFlex installation directory to your PATH? I don't remember doing that ever; is it the same JFlex as I have used?

This is the exact instruction:

Edit the file bin\jflex.bat (in the example it's C:\JFlex\bin\jflex.bat) such that
JAVA_HOME contains the directory where your Java JDK is installed (for instance C:\java) and
JFLEX_HOME the directory that contains JFlex (in the example: C:\JFlex)

I set JAVA_HOME to where my jdk is: C:\Program Files\Java
and JFLEX_HOME to where the jFlex is: C:\Documents and Settings\Hunter\Desktop\jflex-1.4.3\lib

Campbell do you see any mistakes??


Thanks

That appears to be the same JFlex I have used (but I used it only on Linux), but surely JAVA_HOME ends with \jdk1_6_0_18 or similar, despite the example they give here?

JFLEX_HOME : C:\Documents and Settings\Hunter\Desktop\jflex-1.4.3\lib

Just a hunch, but that should probably be C:\Documents and Settings\Hunter\Desktop\jflex-1.4.3 (without the "\lib")
