Title: Install javax.comm API
Post by: diegorandal on June 15, 2013, 11:17:32 AM

Need to use the Serial Port from Java. Java works ok.
I have followed all the tutorials but I could not make it work.
If someone has managed to install this Java library for the use, please tell me what steps to take.

I have the files of the api: libLinuxSerialParallel.so; comm.jar and javax.comm.properties
Also I have the RXTX files ... but with them does not work.

Java is installed in: / usr/local/openjdk-7/jre

If I consult the CLASSPATH get: "/apps/xfe/lib::/usr/java/packages/lib/i386:/lib:/usr/lib"

Thank you. Sorry for the English, use a translator.

Hi diegorandal
Besides it not working, do you receive any error messages?

Well, did you check for above?

Seems to be quite complex...

If I do not include the library javax.comm the plugin works fine.
