The Java comm extension has been discontinued for MS Windows; there is a replacement (it's free): http://rxtx.org; all the details are in the installation notes, read them.

kind regards,

You don't need to do anything special for Eclipse; just store the .jar file in your JRE/lib/ext directory; the API documentation for Sun's javax comm applies here one to one because the APIs are identical. The rxtx package also comes with documentation, why not read it?

kind regards,

Yes I did copied jRe/lib/ext. But still when I typed in eclipse (" import javax.comm.*;) it doesn't work. I am using window 7 64 bit. Please reply to me.

Thanks

But of course, how silly of me to assume that you'd read the accompanying documentation: those classes are in the gnu.io package not in the javax.comm package.

You can't import javax.comm.* classes because they are not there. The rxtx package stores its classes in package gnu.io so you should do "import gnu.io.*".

I don't think they'll be happy until you've written all the code for them...

This thread is driving me nuts (if I wasn't completely insane already ;-) It's as if they don't read my replies and keep on doing stuff they're not advised to do ... I realize that the rxtx documentation is a bit scattered over the net but that's nothing Google can't solve.

kind regards,
