java - AS/400 Message queue filtering - JT400 (JAVA)

Question

1. I'm trying to get queue message list. I already did it using this code. problem is i want to filter it to *inq. this code retrive all messages. but i want to get *inq messages only. how to do it ?
2. I was used "/qsys.lib/qsysopr.msgq" to get QSYSOPR message queue messages. I want to get all message queue's messages. So whats the exact queue path to get all message queue's messages.

Thanks in Advance!

try {
    AS400 system = new AS400();
    MessageQueue queue = new MessageQueue(system, "/qsys.lib/qsysopr.msgq");
    Enumeration e = queue.getMessages();
    while (e.hasMoreElements()) {
        QueuedMessage message = (QueuedMessage) e.nextElement();
        System.out.println(message.getText());
    }
    System.out.println("End Messages!");
} catch (Exception e) {
    e.printStackTrace();
}

Answer 1

1) 过滤 *INQ 消息的一种方法是使用如下内容：

MessageQueue queue = new MessageQueue(system, "/qsys.lib/qsysopr.msgq");

// want only inquiry messages
queue.setSelectMessagesNeedReply(true);
queue.setSelectMessagesNoNeedReply(false);
queue.setSelectSendersCopyMessagesNeedReply(true);

Enumeration e = queue.getMessages();

2) 可以在系统上的任何库中创建消息队列。为了从所有消息队列中获取所有消息，您需要像这样使用 ObjectList：

import java.util.*;
import com.ibm.as400.access.*;

public class TestObjectList {
    public static void main(String[] args) {

try {
    AS400 system = new AS400();

    ObjectList msgqs = new ObjectList(system, ObjectList.ALL, ObjectList.ALL, "*MSGQ");

    Enumeration e = msgqs.getObjects();

    while (e.hasMoreElements()) {
        ObjectDescription msgq = (ObjectDescription) e.nextElement();
        System.out.println(msgq.getLibrary() + "/" + msgq.getName());
        }

    System.out.println("End of message queues.");

    } catch (Exception e) {
      e.printStackTrace();
    }

System.exit(0);
}

}
