Question

I wanted to use jFlex. Tried to search online tutorials. But all points to the same link.
I could not successfully set up and use Flex on my machine.
It would be great if some one could point me to a good tutorial.

Thanx in advance.

Answer 1

I have set this up recently on my 64 and 32 bit windows 7 systems. Here’s what I did:

1. Installed the extracted JFlex under my C:.
2. Went into the bin folder (C:\jflex\bin) and edit the JFlex.bat file in my Notepad++
3. There are two paths that need to be edited “JFLEX_HOME” and “JAVA_HOME”.
4. Because of my folder structure, I don’t have to change “JFlex_HOME”, but depending where you have installed it you may need to point to a different directory.
5. JAVA_HOME – You have to browse your programs directory and find your java jdk installation. My JAVA_HOME variable is as follows:
   set JAVA_HOME=”C:\Program Files\Java\jdk1.6.0_20″
6. Save changes and run the jflex.bat program in the cmd pmt and you should be good to go.

I hope this helps.
