You are referring to the logic used to call an external executable I suppose? GRASS is a bit complicated in that respect, it requires some work to setup the right environemt also in terms of directories and so on (the location and mapset), unless things have been simplified quite a bit since I last looked. Checking the 52 North integration, it still seems to be more than just "call an external executable with some command line options", although I cannot say I recognize this from my past experiences, it seems they are using some python command line intermediary: https://github.com/52North/WPS/tree/dev/52n-wps-grass/src/main/java/org/n52/wps/server/grass Going back to calling executables, Stefano's work builds on top of the existing OGR module, recently I added the ability to call gdal_translate in importer, and I've setup a generic command line transformation, but used a different library, which has been suggested by some colleagues of mine since it supports timeouts: https://github.com/geoserver/geoserver/blob/master/src/extension/importer/core/src/main/java/org/geoserver/importer/transform/AbstractCommandLineTransform.java Maybe code extracted from it could be a better base for a generic command line calling tool Cheers Andrea -- == GeoServer Professional Services from the experts!
