Example 1 with NullProgressListener

use of org.geotoolkit.util.NullProgressListener in project geotoolkit by Geomatys.

the class WPSClientDemo method main.

public static void main(String[] args) throws Exception {
    // force loading all image readers/writers
    ImageIO.scanForPlugins();

    // Once initialized, we can ask a description of wanted process, using its id.
    final WPSProcessingRegistry registry = new WPSProcessingRegistry(wpsClient);
    ProcessDescriptor desc = registry.getDescriptor(PROCESS_ID);
    // We can check process input & output.
    ParameterDescriptorGroup inputDesc = desc.getInputDescriptor();

    // Iterate on wanted parameters. If one is missing, an exception is raised.

    // parameter, an exception is thrown.
    ParameterValueGroup input = inputDesc.createValue();
    input.parameter(INPUT.geom.name).setValue(geometry);
    input.parameter(INPUT.distance.name).setValue(bufDistance);
    // Process execution. It's synchronous here (talking only of client side, WPS can execute asynchronous process).
