Ah ha, I'll fix that. > Even with the correct URL I am getting a stack trace from GeoServer: > >> org.geoserver.wps.WPSException: Could not find process parameter for >> type LAYERS,class java.util.ArrayList >> at org.geoserver.wps.DescribeProcess.dataInputs(DescribeProcess.java:126) >> at >> org.geoserver.wps.DescribeProcess.processDescription(DescribeProcess.java:101) >> at org.geoserver.wps.DescribeProcess.run(DescribeProcess.java:77) >> at >> org.geoserver.wps.DefaultWebProcessingService.describeProcess(DefaultWebProcessingService.java:62) That I guess is the Sextante mapcalc equivalent? (raster algebra over multiple layers?). At this stage of development GeoServer can bind only processes following certain input/output types and certain rules, one of them is that explicit collections are not allowed, since there's no way to know what's inside them, and a parameter with a binding of the type of the contents of the collection, and multiplicity > 1 (or -1 to specify no limit) should be used instead. So it describe and execute should work for some processes, but not all of them. I guess I should filter the processes we cannot properly bind out of the capabilities > On the plus side some good news for the geotools-devel list: > - I have restored the unsupported/wps module test cases > - there is a test fixture to check against a local geoserver if you have it > - I am building up a stable of sample xml documents to parse against Nice Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
