java.lang.noclassdeffounderror

[Former Member]

i know that normally this error is because of the classpath and the path, but i think that it is correctly.

my classpath is:

.;C:jorgejdkpruebael apiCOMMAPIcomm.jar;C:j2sdk1.4.2_04lib ools.jar

and the path is:

C:j2sdk1.4.2_04 in

i am using the javax.comm packet, i can compile good the class, but i can´t execute it, it gives me java.lang.noclassdeffounderror.

does anybody know the error?

thanks in advance.

Hi Carl,

it seems, that you have the javax.comm jar(s) added to your build path but not to the classpath used at runtime.

thank you very much, it runs know, but i have another problem, my program doesn´t detect the ports, and i have probed with the SerialDemo.java that comes with the packet that would read the ports, do you know if i have to configure or active them in special way? perhaps in the control panel..

thanks in advance and best regards

No, sorry, this is too much javax.comm specific. I suggest to have a look at the official Sun documentation available for this package.
