Hi Gabriel and all,
Thank you for help me. But now, I get another problem. When I trying to
generate the filter with this code, I get an incomplete geometry filter
encoding. Follows the source code:
FilterFactory2 ff = (FilterFactory2)CommonFactoryFinder.getFilterFactory(
null );
PropertyName propertyName = ff.property( "testString" );
Literal literal = ff.literal( 2 );
PropertyIsEqualTo filter = ff.equals( propertyName, literal );
GeometryFactory gf = new GeometryFactory();
Coordinate c = new Coordinate(-38.0, -7.0);
Point p = gf.createPoint(c);
Filter f = ff.contains(ff.property("SERVICEBBOX"), ff.literal(p));
Or orFilter = ff.or(filter, f);
// create the encoder with the filter 1.0 configuration
org.geotools.xml.Configuration configuration = new
org.geotools.filter.v1_0.OGCConfiguration();
org.geotools.xml.Encoder encoder = new org.geotools.xml.Encoder(
configuration );
// create an output stream
OutputStream xml = new
FileOutputStream("C:\\eclipse\\workspace\\WebServiceDescriptionTool2\\src\\test\\geoTest4.xml");
// encode
encoder.encode( orFilter, org.geotools.filter.v1_0.OGC.Filter, xml );
Follows the filter encoding generated:
<ogc:Or>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>testString</ogc:PropertyName>
<ogc:Literal>2</ogc:Literal>
</ogc:PropertyIsEqualTo>
<ogc:comparisonOps />
<ogc:Contains>
<ogc:PropertyName>SERVICEBBOX</ogc:PropertyName>
<gml:Point/> Incomplete Geometry inconding - where are the
coordenates ?
</ogc:Contains>
</ogc:Or>
I think that I am forget anything else to do in the code or anything that I
don't know. Anyone knows what's happening ? Thanks in advance.

as for creating the filter you want, you'll need to cast FilterFactory to
FilterFactory2. Rationale is that the geoapi FilterFactory methods are
meant
to represent exactly the filter building capabilities expressed in the
spec.
The Filter interfaces have actually more expressing power then what the
factory allows, so FilterFactory2 exposes it full fledged:
FilterFactory2 ff = (FilterFactory2)CommonFactoryFinder.getFilterFactory(
null );
Geometry geom = ... //whatever you want to get the geometry from
Filter filter = ff.contains(ff.property("SERVICEBBOX"), ff.literal(geom));
...
hope that helps
Gabriel
