Cool - I am using up my time today with Tim looking at a WFS memory leak. We *need* to set up a unit test for this (somehow?) before we can work on it... can you isolate your example into a JUnit test? That way I can just cut and paste - also if we can arrange a time to meet on the #geotools IRC channel we can work through this together.
By setting a break point in the WFSDataStore.getFeatureReader method you should be able to watch it make (or not make) your Query. Stepping through this code once with a debugger should tell what we need to fix fault :-) Cheers, Jody > hi Jody, > thanks for the reply - I didnt see it before I posted again, but here is a > cut > down variation with part of the filter I am using. - however it doesnt seem > to > matter how simple I make the filter, nor what type, it always runs it > clientside. > > 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()){... > > Quoting Jody Garnett <[EMAIL PROTECTED]>: > > >> Darn this sounds messy. >> >>> (Sorry for the duplicate post, but thought it better to include a subject >>> >> line.) >> >>> I'm a geotools newbie, but I've setup geoserver and am querying it via >>> >> wfs. >> >>> I've created a client application using geotools 2.2.4 (I did not find it >>> >> easy >> >>> from scratch with the doco thats available) >>> >> Can you help us update the docs? >> >>> , I construct a filter and add it to >>> a query from which I get results. the trouble is that the query only ever >>> >> sends >> >>> a this query and never includes my filter (it does use maxFeatures and >>> >> typeName >> >>> settings though). >>> eg: from serverlog - >>> <?xml version="1.0" encoding="UTF-8"?> >>> <GetFeature xmlns="http://www.opengis.net/wfs"; >>> >> xmlns:gml="http://www.opengis.net >> >>> /gml" xmlns:ogc="http://www.opengis.net/ogc"; version="1.0.0" service="WFS" >>> >> outpu >> >>> tFormat="GML2" maxFeatures="10"><Query >>> >> typeName="sde:TOPO.GAZETTEER"></Query> >> >>> </GetFeature> >>> >>> the filter does get used - but its run clientside. >>> >>> >> I can see - can you tell me the filter code?
