I have got some .lx files and hav converted them to .c .they are working properly

now i need them to convert to flex files so that i can get .java files thru jflex any help or any tutorials for tht please

AFAIK, anything that lex can process, flex can process. As far as using it to generate java code, that I cannot speak to.

i converted the flex files to java code through jflex and while running i got following errors

I'll hazard a guess, based on how flex works in the C universe. I think your java code may require a class library that is part of the flex package. In C, you have to link flex output with libl.a. In java, there may be a similar library. This is, as I say, speculation.

even if the java code are generated by jflex itself????

The online documentation for jflex states 'include the file lib\JFlex.jar in your CLASSPATH environment variable'.
