Mon, 26 Jan 2026 18:19:17 GMT

Hi all,

I'm trying to load Qlikview Document in simply java class. I've an unexcepted error. (cf screenshot). The SDK Example [Selections.java] have the same error.

Thanks for your help, Clément

Here, my java code :

import com.qt.qw.beans.QlikSession;
public class myFirstQVProgram {
 private QlikSession session;
 public static void main(String[] args) { new myFirstQVProgram().Test(); }
 public void Test(){ session = new QlikSession(); session.setUserName("QLIKOPORTABLE\\qlikweb"); session.setPassword("qlikweb"); session.setDocName("Films.qvw"); session.openDocument(); }
}

Here, the corresponding console :

It's OK, I fund the problem.

I must have a ticket from the QV Sever. When I have the ticket, i put it in the userame.

QlikSession session = new QlikSession();
session.setUserName("3E8E8719A4E8F0A8E0CDDCFE65BB6BCCF02C9B0C");//my ticket

 session.setDocName("test.qvw");

Hi, Clément

I´m trying to create a simple java class, just the same as you, to access the objects from a qlikview file and store in a java bean object. I even tried to use the same java class that you mentioned above but it didn´t work because I don´t have the class QlikSession that you imported. Would you happen to have an example of a project just like the one you did above? As a matter of fact, I´d appreciate if you could explain to me how do you connect to the qlikview from java. I appreciate your help.

Hi Eduard,

Did you connect to qlikview from java ?

I'm trying but I get the following error message:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

fruits = session.openDocument().getField("X");

I noted the session.openDocument() return null value.

Below a piece of my code:

session = new QlikSession();
session.setQvsIP("192.168.76.70");
session.setUserName("username");
session.setPassword("password");
session.setDocName("FruitColor.qvw");
QixDoc qcDoc = session.openDocument();

qcDoc is null !!!

Can you help me?

Thanks in advance.

Best regards

Hi Clément,

Could you send me the project you have attached a screenshot. I need a java program to connect. And I also don´t know what jar I should include.
