Re: [Geotools-gt2-users] [Geotools-devel] An issue about showing more than one shpfilesusing Swing component

[Ian Turton]

First you create a JMapFrame and a MapContent to put in it

JMapFrame frame = new JMapFrame();

  private MapContent content = new MapContent();

  public MapViewer(String[] args) {
frame.setSize(300, 300);

frame.enableToolBar(true);
frame.enableStatusBar(true);
frame.setMapContent(content);

}

Then for each Shapefile (or other datasource) you create a layer and add it
to the MapContent

HashMap params = new HashMap<>();
File f = new File(name);
params.put("url", URLs.fileToUrl(f));
DataStore ds = null;
try {
  ds = DataStoreFinder.getDataStore(params);
} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
if (ds == null) {
  System.err.println("couldn't find a store for " + name);
  return;
}
String type;
try {
  type = ds.getTypeNames()[0];

  FeatureLayer layer = new FeatureLayer(ds.getFeatureSource(type),
style);
  System.out.println("adding layer " + name);

  content.addLayer(layer);
} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}

I've attached the full example to this message.

Re: [Geotools-gt2-users] Geotools Error on SBT Assembly

[Ken]

Thank you for the succint replies! SBT assembly does exclude files inside
the META-INF directory (https://github.com/sbt/sbt-assembly/issues/11). I
know what to do now, thanks again!
