Re: [Geotools-gt2-users] WFS-T Appending to Existing Data

[Aaron J. <yo...@ml...>]

Ok, I've looked through the test code now and am still having trouble. 
When it gets to the commit line I get the following IOException:
java.io.IOException: An error occured
 	at org.geotools.data.wfs.WFSTransactionState.commit(WFSTransactionState.java:135)
 	at org.geotools.data.DefaultTransaction.commit(DefaultTransaction.java:176)

Also, when I'm trying to add a city to the topp:tasmania_cities feature, 
is this the proper way to go about doing it?
--
             FeatureStore fs = (FeatureStore)ds.getFeatureSource(ft.getTypeName());
             fs.setTransaction(t);
             FeatureCollection fc = fs.getFeatures();
             fc.add(new Object []{someMultipoint, "valuea", "valueb", "valuec", "valued"});
