Reading and writing UMN MapServer XML-Mapfiles with Java

Building from source

$ git clone https://github.com/JuergenWeichand/java-mapfile.git
$ cd java-mapfile
$ mvn clean install

Create a new Map instance

Map map = new Map();
map.setName("OGC:WMS");
map.setVersion("7.0.0");
map.getProjection().add("init=epsg:31468");
map.getExtent().add(4264375d);
map.getExtent().add(5216375d);
map.getExtent().add(4670625d);
map.getExtent().add(5622625d);

// OutputFormats
map.getOutputFormat().add(buildOutputFormat(MapFactory.Format.AGG_PNG));
map.getOutputFormat().add(buildOutputFormat(MapFactory.Format.AGG_JPEG));

// Web
Web web = new Web();
ItemType webMetadata = new ItemType();
webMetadata.getItem().add(buildItem("wms_title", "Java XML-Mapfile Demoserver"));
webMetadata.getItem().add(buildItem("wms_onlineresource", "http://geoserv.weichand.de/cgi-bin/test-xmlmapfile.cgi"));
webMetadata.getItem().add(buildItem("wms_enable_request", "*"));
webMetadata.getItem().add(buildItem("wms_srs", "EPSG:31468 EPSG:31467 EPSG:4326 EPSG:4258 EPSG:25832 EPSG:25833"));
webMetadata.getItem().add(buildItem("wms_encoding", "UTF-8"));
web.setMetadata(webMetadata);
map.getWeb().add(web);

// Layer
Layer layer = new Layer();
layer.setName("gemeinden");
layer.setType("POLYGON");
layer.setData("/home/wei/linux-geodatenserver-beispiele/vektordaten/verwaltungsgrenzen/gmd_ex.shp");
layer.setStatus("ON");
layer.getProjection().add("init=epsg:31468");

// Layer Metadata
ItemType itemType = new ItemType();
itemType.getItem().add(buildItem("wms_title", "Gemeinden"));
itemType.getItem().add(buildItem("wms_abstract", "Gemeinden in Bayern"));
layer.setMetadata(itemType);

// Layer Style
Class clazz = new Class();
clazz.setName("Polygon");
clazz.setColor(buildRgbColorType(232, 232, 232));
clazz.setOutlineColor(buildRgbColorType(32, 32, 32));        
layer.getClazz().add(clazz);

map.getLayer().add(layer);

Write Map instance to file

final File mapFile = new File("/tmp/javamapfile.xml");
MapfileIO.writeXmlMapfile(map, mapFile);

Read Map instance from file

final File mapFile = new File("/tmp/javamapfile.xml");
Map map = MapfileIO.readMapFromFile(mapFile);
