Problem with SpeechSynthesis on P.463 of the book

[muimui]

1. Should the first import statement be changed to "import icommand.nxtcomm.*;"
2. There is no "open" method defined in the NXTCommand class.

After making change to the import statement and commented the line "NXTCommand.open();, I am able to compile the program and run the program now. However, it gave the following error:

Exception in thread "main" java.lang.NoClassDefFoundError:
gnu/io/PortInUseException.

I have already set up the RXTX.jar file in the classpath setting according to the readme file and actually I was also able to run the sample program "RemoteControl" last night rotating the motors remotely from the same laptop computer.

I don't know why I have this error again with this program.
Please help!

Hi there. Now that the new leJOS NXJ is released we're going to do another release of iCommand that has all the updated commands, including open(). I think it's been at least 5 months since we updated iCommand so of course it is behind. I'm going to try to get the iCommand release out within a week and that will solve your problems.
