I have found a solution with OpenSource Project Jacob

package Activex01;

import com.jacob.activeX.*;
import com.jacob.com.*;

public class getContacts {
public static void main(String[] args) {
final int olFolderContacts = 10;

ActiveXComponent ol = new ActiveXComponent("Outlook.Application");
Dispatch dsp = new Dispatch();

Dispatch olo = ol.getObject();
Dispatch myNamespace = Dispatch.call(olo, "GetNamespace",
"MAPI").toDispatch();
Dispatch myFolder = Dispatch.call(myNamespace, "GetDefaultFolder",new
Integer(olFolderContacts)).toDispatch();

//nächste zeile Fehlermeldung

Dispatch items = Dispatch.get(myFolder, "Items").toDispatch();

int count = Dispatch.call(items, "Count").toInt();

for (int i = 1; i <= count; i++) {
Dispatch item;
item = Dispatch.call(items, "Item", new Integer(i)).toDispatch();

String fullName = Dispatch.get(item, "Fullname").toString();
String emailAddress = Dispatch.get(item, "Email1Address").toString();
String addressStreet = Dispatch.get(item, "BusinessAddressStreet")
.toString();
String addressCity = Dispatch.get(item, "BusinessAddressCity")
.toString();
String addressCountry = Dispatch.get(item, "BusinessAddressCountry")
.toString();
String addressPostalCode = Dispatch.get(item,
"BusinessAddressPostalCode").toString();
String addressState = Dispatch.get(item, "BusinessAddressState")
.toString();
String title = Dispatch.get(item, "Title").toString();
String phone = Dispatch.get(item, "BusinessTelephoneNumber")
.toString();
String fax = Dispatch.get(item, "BusinessFaxNumber").toString();

printField("", fullName);
printField("", title);
printField("", addressStreet);
printField("", addressCity);
printField("", addressState);
printField("", addressPostalCode);
printField("", addressCountry);
printField("Tel:", phone);
printField("Fax:", fax);
printField("Email:", emailAddress);

System.out.println();
}
}

public static void printField(String label, String value) {
if (value.length() != 0) {
System.out.println(label + " " + value);
}
}
}
