how can I list collections?

[Philipp Chudinov]

Hi! How can I list collections? This code gives an error

String[] colindex = null;
String driver = database_driver;
         Class c = Class.forName(driver);

         Database database = (Database) c.newInstance();
         DatabaseManager.registerDatabase(database);
         String r = database_prefix+parent;
         System.out.println("gettin collection list"+r);
         col = DatabaseManager.getCollection(r);
         colindex = col.listCollections();

at col.listCollections(); 
ru/evolve/innersmile/Connector.java [74:1] cannot resolve symbol
symbol  : method listCollections  ()
location: interface org.xmldb.api.base.Collection
         colindex = col.listCollections();
