Re: [udig-devel] how to create 2 createTemporaryResource from same resou

[Jesse Eichar <jesse.eichar@xxxxxxxxxxxxxx>]

Nothing obvious springs to mind.  A couple questions though:

Does the exception occur in the first addFeatures or second?  

Could you also print out the FeatureType that has been created?

Thanks,


Jesse

Hi
I need create 2 TemporaryResource to show the same GeoResource but using different filter.
I faild and I found the problem is the same name in tempresource. Then I use FeatureTypeBuilder to setName.

the code is :

IService resources = getResource(monitor);// get all tables
            for (IGeoResource resource : resources.resources(monitor)) {
                if (resource.getIdentifier().

getRef().equalsIgnoreCase("customers")) {
                    FeatureCollection fc1 = null;
                    FeatureCollection fc2 = null;
                    FilterFactory filterFactory = FilterFactoryFinder.createFilterFactory();
                    Filter filter1 = filterFactory.createCompareFilter(CompareFilter.COMPARE_EQUALS);
                  
                    Filter filter2 = filterFactory.createCompareFilter(CompareFilter.COMPARE_EQUALS);
                     
                    ((CompareFilter) filter1).addLeftValue(filterFactory.createAttributeExpression("CUSTOMER_ID"));
                    ((CompareFilter) filter1).addRightValue(filterFactory.createLiteralExpression(Integer.valueOf(scno1)));
                
                    ((CompareFilter) filter2).addLeftValue(filterFactory.createAttributeExpression("CUSTOMER_ID"));
                    ((CompareFilter) filter2).addRightValue(filterFactory.createLiteralExpression(Integer.valueOf(scno2)));
                  
                   
                    fc1 = resource.resolve(FeatureSource.class, monitor).getFeatures(filter1);
                    FeatureTypeBuilder builder = FeatureTypeBuilder.newInstance(fc1.getFeatureType().getTypeName());
                    builder.importType(fc1.getFeatureType());
                    builder.setName( "CUSTOMERS" );
                    IGeoResource geoResource1 = CatalogPlugin.getDefault().getLocalCatalog().createTemporaryResource(fc1.getSchema());
                    FeatureStore featureStore1 = geoResource1.resolve(FeatureStore.class, monitor);
                    featureStore1.addFeatures(fc1);
                    localresources1.add(geoResource1);

                    //ApplicationGIS.addLayersToMap(map1, Collections.singletonList(geoResource1), 0);

                    fc2 = resource.resolve(FeatureSource.class, monitor).getFeatures(filter2);
                   
                    FeatureTypeBuilder builder1 = FeatureTypeBuilder.newInstance("customer");
                    builder1.importType(fc1.getSchema());
                    builder1.setName("customer2");
                   
                    FeatureTypeBuilder builder2=FeatureTypeBuilder.newInstance("CUSTOMERS");
