Hello, I had no response from my previous email so trying again. please can somebody tell me what I need to do to get a WFS query INCLUDING the filter sent to a WFS server for processing? Everything I have tried sends a minimal WFS request and then does all the filter processing clientside which is not only slow but also the results are incorrect. this is because the maxresults attribute and the typename is set in the request but nothing else is, so only a minor percentage of my data is being filtered. If I dont set maxresults then I get correct answers but it takes at eternity. I'm sure theres a way to do this but I dont know what I'm doing wrong.
this is essentially my code - geotools 2.2.4 - in essence it works but does all the processing clientside. I want to send the query to the server as a proper WFS request. I hope someone can see what I am doing wrong? DataStore data=null; String getCapabilities ="http://...";; Map connectionParameters = new HashMap(); connectionParameters.put("WFSDataStoreFactory:GET_CAPABILITIES_URL", getCapabilities ); connectionParameters.put(WFSDataStoreFactory.PROTOCOL.key,Boolean.FALSE); data = DataStoreFinder.getDataStore( connectionParameters ); String pattern = "sometext"; String typeName = typeName ="sde:TOPO.GAZETTEER"; org.opengis.filter.FilterFactory2 ff =(FilterFactory2) CommonFactoryFinder.getFilterFactory(null); FeatureType ft=wfsstore.getSchema(typeName); //is there a simpler way to do this? Vector column=new Vector(); for (int i = 0; i < ft.getAttributeCount(); i++) { if (!ft.getAttributeType(i).getName().equals("SHAPE")) { Expression left = ff.property(ft.getAttributeType(i).getName()); Expression right= ff.literal(pattern); column.add(ff.equal(left, right, false)); } } BinaryLogicOperator blo=ff.or(column); DefaultQuery query = new DefaultQuery(typeName,blo); query.setMaxFeatures(100); FeatureSource fs = wfsstore.getFeatureSource(typeName); FeatureCollection results = fs.getFeatures(query); Iterator fr = results.iterator(); while (fr.hasNext()){...
