Re: how to get collections tree from xindice

i know how to get ChildCollections and built collection tree
but also i have to get documents stores in particular collections. There are 
methods like getDocumentsCount() and listDocuments() in 
org.apache.xindice.core.Collection class but this class isn`t work with 
org.xmldb.api.DatabaseManager so i cant register database. Maybe there is 
another way to register database using org.apache.xindice.core.Collection 
class? or there is another way to listDocumetns and count their number??

DBConnection.java
package praca.app;



import org.xmldb.api.base.Database;
import org.xmldb.api.DatabaseManager;



public final class DBConnection
{
  public String addressIP;
  public String port;
  protected static Database db = null;




  Database getDB() throws Exception
  {

     try
  {
     db = 
(Database)Class.forName("org.apache.xindice.client.xmldb.DatabaseImpl").newInstance();
     DatabaseManager.registerDatabase(db);
  }
     catch(Exception e)
  {
      System.out.println(e.getMessage());
      e.printStackTrace();
  }
    return db;
  }


}
