IBM MQ - 2035 using java MQQueueConnectionFactory

Question

I'm using IBM java librarys to connect an IBM MQ system.

  <dependency>
        <groupId>com.ibm.mq</groupId>
        <artifactId>com.ibm.mq.allclient</artifactId>
        <version>9.4.1.1</version>
    </dependency>

My settings are:

   MQQueueConnectionFactory factory = new MQQueueConnectionFactory();
   factory.setHostName("myserver");
   factory.setPort(1451);
   factory.setQueueManager("TIPPP");
   factory.setChannel("TIPPP.CL.GGG");
   factory.setTransportType(WMQConstants.WMQ_CM_CLIENT);
   factory.setUserAuthenticationMQCSP(true);

when trying to open the connection:

    connection = (MQQueueConnection)
                factory.createQueueConnection("usr","llalalalalalalalalalalalalalaal");
    // Yes, the pwd is quite long

I receive this response:

   Caused by: com.ibm.mq.MQException: JMSCMQ0001: Der IBM MQ-Aufruf ist mit Beendigungscode '2' ('MQCC_FAILED') und Ursache '2035' ('MQRC_NOT_AUTHORIZED') fehlgeschlagen.

I contacted the IBM MQ Admin and he told me that my user has no right to execute an "inquire" on the queuemanager. I do have rights for the queue itself, but not to execute this on the manager.

  AMQ8077W: Entity 'usr' has insufficient authority to access object TIPPP
            [qmgr].

  EXPLANATION:
  The specified entity is not authorized to access the required object. The
  following requested permissions are unauthorized: inq
  ACTION: ...

I tried everything: ConnectionFactory, QueueManagerFactory.. but it always runs this inquire on the manager.

Do I have to adjust my connection settings or is this right to call an inquire just necessary for the (java) library? I have to mention that I want to write in one queue and have a listener on another queue for receiving.

Thanks!

All Object-Oriented Languages (i.e. Java, C#, etc.) that connect to a queue manager require 'inquire' privileges on the queue manager and 'inquire' privileges on any queues that are opened by the application.
