Hi, thanks!!... but I couldn't make it work. I download de source code for
debbuging and I see something that I don't understand.
I'm do it this:
*DataStore data = DataStoreFinder.getDataStore( connectionParameters );*
In the class DataStoreFinder the method call the getAvailableDataStores(),
this return ShapeFileDataStore and MifFileDataStore in a HashMap.
This is the method
*DataStoreFinder*
public static synchronized DataStore getDataStore(Map params) throws
IOException {
Iterator<DataStoreFactorySpi> ps = getAvailableDataStores();
DataAccess<? extends FeatureType, ? extends Feature> dataStore;
dataStore = DataAccessFinder.getDataStore(params, ps);
return (DataStore) dataStore;
}
*this is the method in DataAccessFinder:*
static DataAccess<? extends FeatureType, ? extends Feature> getDataStore(
Map<String, Serializable> params, Iterator<? extends
DataAccessFactory> ps)
throws IOException {
DataAccessFactory fac;
IOException canProcessButNotAvailable = null;
while (ps.hasNext()) {
fac = (DataAccessFactory) ps.next();
boolean canProcess = false;
try {
*canProcess = fac.canProcess(params);*
} catch (Throwable t) {
LOGGER.log(Level.WARNING, "Problem asking " +
fac.getDisplayName()
+ " if it can process request:" + t, t);
// Protect against DataStores that don't carefully code
// canProcess
continue;
}
* if (canProcess) {*
.....code here.....
}
}
if (canProcessButNotAvailable != null) {
throw canProcessButNotAvailable;
}
return null;
}
*Then canProcess return false with this method*
*ShapefileDataStoreFactory*
public boolean canProcess(Map params) {
boolean accept = false;
* if (params.containsKey(URLP.key)) {*
try {
URL url = (URL) URLP.lookUp(params);
accept = canProcess(url);
} catch (IOException ioe) {
// yes, I am eating this - since it is my job to return a
// true/false
}
}
return accept;
Becouse of this method (*canProcess*), ther return of *getDataStore* is
null. This line *params.containsKey(URLP.key) *, search for a key with the
value "*url*". But the value of the key that I send is "*
WFSDataStoreFactoy:GET_CAPABILITIES_URL*". And if I put the key value "*url*"
then search for "*.shp*" so my URL to geoserver is useless.
I'm using gt-main.jar and gt-shapefile.jar, version 2.6-M2. Maybe *
getAvailableDataStores()* has to give me more than 2
(org.geotools.data.mif.MIFDataStoreFactory,
org.geotools.data.shapefile.ShapefileDataStoreFactory).
Anyone has this problem? or has this running?.... If you have this running
please look what is the result of this.
*DataStoreFinder.getAvailableDataStores();*
Thanks a lot!!!..
Eze.
