Hi,

i am using Java SDK 1.4.1 including JRE on an WinXP machine. I want to use the Communications API
I did follow the installations instructions:

Place the win32com.dll in <jdk>\jre\bin directory.
Place the comm.jar in <jdk>\jre\lib\ext.
Place the javax.comm.properties in <jdk>\jre\lib .
Do not alter the CLASSPATH.

When trying to run a java program using the new class i get the following error:

Exception in thread &quot;main&quot; java.lang.NoClassDefFoundError: javax/comm/CommPortIdentifier at ...

please help
