Hi,

*I have a simple program that loops through a SimpleFeatureCollection.*

* public SimpleFeatureSource source;

public class myclass()
{

     public void execute()
        {
              try {

                        SimpleFeatureCollection featuresIn =
source.getFeatures();
                         System.out.println(featuresIn.size());
              } catch (Exception e) {
                 e.printStackTrace();
               }

        }

}


**I call execute function from other class like this:*

*public class test()
{

     public static void main(String args[])
        {
              try {
                             File file= new
File("C:\\tt\\POA_2011_AUST.shp");
                             Map map = new HashMap();
                             map.put( "url", file.toURL() );
                             DataStore dataStore =
DataStoreFinder.getDataStore( map );
                            SimpleFeatureSource source;
                            String typeName =
dataStore.getTypeNames()[0];
                            source = dataStore.getFeatureSource(typeName);

                            myclass testclass=new myclass();
                            testclass.source = source;
                            testclass.execute;

               } catch (Exception e) {
                 e.printStackTrace();
               }

        }

}
*

*after running my program it shows:*

*java.lang.UnsupportedOperationException: AutoCommit does not support the
getState opperations*

Could you please have a look and see why it happens?
