unsatisfied link: SolarisParallel using rxtx to replace java comm api in Windows XP

Question

Hi everyone, i'm trying to use the rxtx 2.0 jars and dll to use the java comm api in windows xp, i copied the RXTXcomm.jar to jre\ext and rxtxSerial.dll and rxtxParallel.dll to jre\bin

When I run the program I got the following error:

Error loading SolarisSerial: java.lang.UnsatisfiedLinkError: no SolarisSerialParallel in java.library.path Caught java.lang.UnsatisfiedLinkError: com.sun.comm.SolarisDriver.readRegistrySerial(Ljava/util/Vector;Ljava/lang/String;)I while loading driver com.sun.comm.SolarisDriver

why is it trying to load the solaris driver?? Thanks in advance

Answer 1

It looks like you may have an improperly configured properties file.

Locate Javax.comm.properties and search for this:

Driver=com.sun.commSolarisDriver

If you find it, comment it out and place it with:

Driver=gnu.io.RXTXCommDriver

This is based on RXTXComm's install-japanese.html file, as translated by Google

Answer 2

For windows, I suggest using "Windows Java Serial Com Port Driver" rather than rxtx. You can download it from http://www.engidea.com/blog/informatica/winjcom/winjcom.html I've found it much easier to install and use and much more bug-free. I was unable to use RXTX with USB serial devices because RXTX would crash when the USB port was unplugged. winjcom solved these problems for me, and more. -Stosh
