Install javax.comm and get it to work!!

[4waystop]

Hi

I'm having trouble installing javax.comm onto j2sdk1.4.2_06. I've put all the files in the place detailed in the documentation, but all I get on running BlackBox is the "No ports found!" error. I'm using Eclipse, so I've pointed the build path to comm.jar. Eclipse is happy with the code and I don't get any problems compiling but as I said when I try to run I get that error. I've tried moving both the .dll and the .properties files into various locations all to no avail. I even deleted them both and I still get the same result!!

So this makes me think maybe I need to point to them in the classpath in some way? All suggestions much appreciated!

Many Thanks

Where did you put the dll ? Is it in the LD_LIBRARY_PATH ?

Sorry - I'm not sure how you get to this path variable. I've gone to the project properties window within eclipse and added comm.jar to the libraries listed withing the java build path. I haven't references the dll file anywhere, just the .jar file.

The dll is in the jdk/dre/bin folder.

Well that sounds OK ...
Have you actually got a serial port on your PC ?

Haha! Yes there's a serial and a parallel port. Neither of them are found with any of the example programs provided with the javax.comm extension. I just get the no ports found error.
