Re: how to get collections tree from xindice

[Marcin Goldyn]

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;
 }


}

CollectionTree.java
import org.xmldb.api.DatabaseManager;
import org.xmldb.api.base.Collection;

public static void ileSpacji(int liczba)
{
 if (liczba>0)
 {
   for (int i=0; i<liczba; i++)
    System.out.print("  ");
 }
}

   {

    int  liczbaKolekcji = (int)kolekcja.getChildCollectionCount();

            }
        }
        */
        System.out.println("</"+tablica[i]+">");

       }
