I got NullPointerExceptions creating a new WPSFactory. The first one happens in org.geotools.data.wps.WPSFactory: private void buildValuesFromProcessDescriptionType():
this.description = this.pdt.getAbstract().getValue(); In net.opengis.wps10.impl.DescriptionTypeImpl getAbstract() returns _abstract and I cannot see any checks that avoid returning null. Trying .getValue() results in the NPE. Since the child element "ows:Abstract" of "DescriptionType" is optional (http://schemas.opengis.net/wps/1.0.0/common/DescriptionType.xsd) it must be checked if null is returned or not. Like this.description = this.pdt.getAbstract()==null?"":this.pdt.getAbstract().getValue(); It's not up to me to decide whether an empty String "" or null for this.description should be used. Using null will result in an IllegalArgumentException in getDescription() during conversion into an InternationalString object. The same problem in org.geotools.data.wps.WPSUtils twice: 1) createInputParamMap(..) Creating the new Parameter Parameter param = new Parameter(idt.getIdentifier().getValue(), type, Text.text(idt.getTitle().getValue()), Text.text(idt.getAbstract().getValue()), required, idt.getMinOccurs().intValue(), idt.getMaxOccurs().intValue(), null, null); 2) createOutputParamMap(..) Parameter param = new Parameter(odt.getIdentifier().getValue(), type, Text.text(odt.getTitle().getValue()), Text.text(odt.getAbstract().getValue()) ); Cheers, Matthias -- Matthias Lendholt [matthias.lendh...@gfz-potsdam.de] tel: +49 331 288 1687; fax: +49 331 288 1703 Deutsches GeoForschungsZentrum (GFZ) Telegrafenberg A20; D14473 Potsdam; Germany ------------------------------------------------------------------------------ Come build with us!
