I used the code below to export an SLD XML, but always getting
exception if I add a NamedStyle for each NamedLayer, any idea? Thanks
a lot!
StyleFactory factory = StyleFactoryFinder.createStyleFactory();
StyledLayerDescriptor sld = factory.createStyledLayerDescriptor();
for(int i=1; i<7; i++)
{
namedLayer = factory.createNamedLayer();
namedLayer.setName(String.valueOf(i));
NamedStyle namedStyle = factory.createNamedStyle();
namedStyle.setName(String.valueOf(i));
namedLayer.addStyle(namedStyle);
sld.addStyledLayer(namedLayer);
}
SLDTransformer transformer = new SLDTransformer();
transformer.setIndentation(4);
String sldXML = transformer.transform(sld);
System.out.println(sldXML);
Always getting
