Please, send this short mail to Walter van Iterson

Hello, I saw on the web site of National Instrument you wrote an JNI developpement for interfacing a PVI 6527 card to Java by the means of JNI.

I have to write a Java software using this card and the java must be notified when an input change.

Is that possible to see your source code ?

Many thans in advance.

Best regards

Hi Ruben,
The plugin is great – thanks.
I had to made one small change to get the ‘Clear All’ to work in the latest jmeter (2.3.1).
Without the change, ‘Clear All’ caused an AbstractMethodError stack trace and the data was not cleared.
The Clearable interface has changed in jmeter_core, so I just changed the method signature from:
public void clear()
to
public void clearData()
and now it works a treat!
Cheers,
Dan

Interesting I will try to merge those changes in the plugin as soon as I have some spare time

Hi Ruben,

Thanks for this plugin. We use its output as part of our deployment/acceptance process. Instead of making a screenshot of JMeter after every measurement run, I’ve changed the code slightly. This way, it writes its chart to a file after a measurement run.

Here are the changes. You might find them useful.

Regards,
Walter van Iterson

In StagAggVisualizer.java, around line 277:

public void testStopped()
{
try {
_model.testStopped();
updateChart();
saveChart();
} catch (Exception e) {
e.printStackTrace();
}
}

/**
* Saves the chart to a file called chart.png, in the directory where
* jmeter was started.
*/
private void saveChart() {
try {
ChartUtilities.saveChartAsPNG(new File(“chart.png”), _chart, 800, 500);
} catch (IOException ioe) {
System.out.println(“Unable to save chart: ” + ioe);
}
}
