Hi
As you have suggested, ths solution from the problem consists in the
substitution of the function getLabel() by the function getText().
But now a new problem as appear:
I'm trying to do what is suggested in the tutorial : "Using Matlab with
TinyOS"
I have a micaz programmed with TOSBase and connected to the pc, via
COM6, and a mote with ID 1 programmed with RfmToLeds. Then i do the
following in Matlab:
>> connect('[EMAIL PROTECTED]');
>> msg=net.tinyos.cntToLeds.LedsMsg
??? Undefined variable "net" or class "net.tinyos.cntToLeds.LedsMsg".
What is the problem now?? Can you give me a help?
Thanks in advance

As I said before, you can either dig through all the java
documentation to try
to figure out what better thing they thought they replaced getLabel()
with, or
you can just ignore the warning.

Hi all:
After doing what Michael Schippling has suggested the following error
occurs:
[EMAIL PROTECTED]
/cygdrive/c/tinyos/cygwin/opt/tinyos-1.x/tools/java/net/
tinyos/matlab
$ javac MatlabClock.java
Note: MatlabClock.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
When i recompile with /-deprecation /the following message appears:
[EMAIL PROTECTED]
/cygdrive/c/tinyos/cygwin/opt/tinyos-1.x/tools/java/net/
tinyos/matlab
$ javac MatlabClock.java -deprecation

^
MatlabClock.java:192: warning: getLabel() in

} else if (((JButton)source).getLabel()==STOP) {

2 warnings
What should i do in this case?
Please give me a help !!
Thanks in advance

Well, you have two things confused to start with.
Your original problem was "javac: not found",
which means that the execution PATH in your shell
(I assume cygwin's bash) is not correct. javac wasn't
found to be executed.
Once the dust clears, you then want to set the CLASSPATH for matlab
to include the results of the make that hitherto has failed to exec.
Fortunately there are two reasonably easy ways to proceed and they
should work for both issues. If you are on MSWidows you can go to
MyComputer-Properties-Advanced-EnvironmentVariables (on XP, I think
it a bit different on NT/W2k). There you should find "Path" in System
Variables. Just add the directory that contains your java install bin,
e.g.: c:\JAVA\j2sdk1.4.2_04\bin (put it BEFORE system32 or you will
get MSbill's version of java by mistake). Also note the delimiter used,
I think it's semi-colon ";" here...
You can set a system CLASSPATH here too. There may already be one to
edit, or create a new one and put all the paths that matlab wants, with
ummmmm....semi-colon....errr....delimiters (I can never remember
which).
You can also do this for only the bash shell (assuming that you start
matlab from a shell prompt). Edit a new batch file and put something
like:
export PATH="/cygdrive/c/JAVA/j2sdk1.4.2_04/bin:$PATH"
export
CLASSPATH="C:/tinyos/cygwin/opt/tinyos-1.x/tools/java;$CLASSPATH"
and whatever other entries you need...note that the separator for PATH
here is colon ':', just to keep us on our virtual toes. Once you write
the file, source it into the shell with: source [filename]
this reads it into your shell environment.
Then you should be able to do:
vincent:~ [257] type java
java is /cygdrive/c/JAVA/j2sdk1.4.2_04/bin/java
There also seems to be a "matlab classpath.txt file" someplace if you
follow Stephen Chou concurrent problems on this list...
As I said, see the man page for bash and also basic java install and
classpath instructions & doc to get a better understanding of setting
these things. Try google CLASSPATH for instance.
Someday this will all be done by computer.

I don't know how to edit the system classpath evironment. I must do
the following:
" It is important to compile the java files present in
'C:\tinyos\cygwin\opt\tinyos-1.x\tools\java\net\tinyos\matlab'
folder. We added the *'C:\MATLAB7\java\jar\jmi.jar'* to the system
class-path to compile. One should not forget to add
'c:\tinyos\cygwin\opt\tinyos- 1.x\tools\java\comm.jar' and
'c:\tinyos\cygwin\opt\tinyos-1.x\tools\java' to the system
class-path to compile. This will compile java files that are needed
to control Matlab through java "
How can i edit the system classpath ??
Thanks

Is the java install /bin directory in your PATH environment variable?
try: type javac or: type java
from the cygwin bash shell.
See: man bash for an excruciatingly long explanation...
