Hello
I'm Laurent from Toulouse

We ordered a new 1052 stand alone temperature sensor.
We had compiled a java software (1.6) to draw a temperature curve and used it nicely with the 1051 version of the sensor.
It doesn't work anymore.

We tried to recompile (with java7) the simple example available in your website (C:\temp\JavaJNI\Simple Examples\TemperatureExample.java).
(Note that the sensor is well detected (and gives a too low temperature for this season !) after installing the phidgets driver and running )

I got a crash:

C:\temp\JavaJNI_2.1.8.20120612\JavaJNI\Simple Examples>java -cp phidget21.jar;.

any idea ?

Cheers.

I haven't seen this error. Can you make sure to install the latest libraries - and also to download the latest phidget21.jar Java library.

Does the sensor work ok if you open it from the control panel?

Hello Patrick.

yes I installed all that fresh in the PC (Windows XP) from your website:
jdk 7
Phidgest 21 Installer
Your java code sample

Yes the T° sensors (1051, the old with big usb connector and the new with small usb connector) work both on the "Phidgets Control Panel"

Then:
- doing make to compile the java classes
- launch the sample for temperature sensor:
java -cp phidget21.jar:. TemperatureExample

then the krash (I did it again this morning just to be sure):



C:\temp\JavaJNI\Simple Examples>java -cp phidget21.jar;. TemperatureExample

Hi,

This is a bug that was introduced in the last library release - 2.1.8.20120612.

I'm releasing a fix now, it should be live in about an hour.

Hello Patrick
Yes, now the simple example: TemperatureExample.java works fine !
I can continue.
Thanks a lot.
Cheers
