Using RXTX In Eclipse
Deploying JAVA with RXTX
I wrote an app several months ago using javax.comm on windows. Sun has left me high and dry. rxtx help!
download ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7-bins-r2.zip
unzip it
copy rxtxSerial.dll into your c:\program files\java\jre-version\bin dir
copy RXTXcomm.jar into your c:\program files\java\jre-version\lib\ext dir
change all references from 'javax.comm' to 'gnu.io'
recompile
test
Dido Sun left me Hi and dry. After 30+ hours wasting my life on
javax.comm it is the RXTXcomm 2.1.7 that really worked the first
time
REMEMBER !! for the newbies
Change the all occurences of the import javax.comm.*; in
MyApps.java
TO import gnu.io.*;
I did not even have to recompile as suggested the rxtxSerial.dll
a job well done for the rxtx.org team.
Even after following the above instructions, under Netbeans 5.5 on Windows, I needed to right-click Libraries
under Projects on the left hand side of the screen, and select Add JAR/Folder, picking the RXTXcomm.jar file.
Only then did my "import gnu.io.*;" become a valid command. Also, I got a run-time error where it failed to
load the rxtxSerial.DLL library because it couldn't find it. I needed to right-click the project name, select
properties, select Run under categories, and ...
add a VM Options: entry of -Djava.library.path="C:/where-ever-you-stuck-rxtxSerial.DLL-file;%PATH%" While I'm sure there is more than one way of adding the directory to your path, this worked for me. Note I did the default NetBeans 5.5/JDK 1.6.0 isntall accepting all the default options(ie clicking next until I got to finish), so I haven't modified my java paths or anything.
