Example 1 with WebProcessingClient

use of org.geotoolkit.wps.client.WebProcessingClient in project geotoolkit by Geomatys.

the class WPSClientDemo method main.

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

    final WPSProcessingRegistry registry = new WPSProcessingRegistry(wpsClient);
    ProcessDescriptor desc = registry.getDescriptor(PROCESS_ID);
    // We can check process input & output.
    ParameterDescriptorGroup inputDesc = desc.getInputDescriptor();
    ParameterDescriptorGroup outputDesc = desc.getOutputDescriptor();
    // Iterate on wanted parameters. If one is missing, an exception is raised.
