If Java is searching the current directory, it isn't going to find that class file no matter what you do. If this doesn't work, show me your CLASSPATH Jva...

It appears to me that your .class file is not their. Or maybe your jre is not installed correctly. Also, why did this code compile when there is no String argument in the RCXPort constructor? As far as I know, the RCXPort constructor needs a String argument--usb, COM to tell it where to write. Oh, l...

One tip: before you install libusb make sure you unplug all external usb devices, and disable(temporarily) all internal usb devices. After libusb is installed, you can enable and plug in the devices again.

Hi,
Maybe you should try java NXJTest. I assume you are testing out the demo NXJTest.class file, and you don't have your own nxjtest.
Maybe this will help.

Since I posted, I tried out the
RCXPort port = new RCXPort(args[0]);
instead of
RCXPort port = new RCXPort();
but the compiler says it can't resolve the constructor with a String argument.
I don't understand it.
Help me! Please!

Also make sure there is a . in your CLASSPATH
For instance my classpath is
.;"i\QTJava.zip";.;C:\;C:\Sun\Java\jre1.6.0_02\lib\ext\QTJava.zip
^
Notice the . in the CLASSPATH. Make sure there is one. Or you can set the claspath with
set CLASSPATH=.
Hope is helps.

Hi, I looked up RCX 0074 on google and i found a page in the lejos tutorial that described what you are experiencing as an exception. I did not read the whole page so I am not completely sure, but that is what I gathered. Here is the google search http://www.google.com/search?sourceid=navclient&...

Possible Help

Hi,
Maybe this will help you. Is the bin directory in your path? If the bin directory of the jdk is not in my path I get the exact same result.
Hope this helps

HI

Hi, I'm not sure if this was a problem in the earlier realese or maybe this just a certain restriction of lejos.
But incase it is neither, I found that an int[] cannot hold more than 512 elements.
