AS400系统与JNDI的连接

AS400 system connection with JNDI

我可以弄清楚如何使用 JNDI 资源通过 jt400 连接到 AS400:

    Connection conn = null;
    Statement stmt = null;
    try {
        Context ctx = (Context) new InitialContext().lookup("java:comp/env");
        conn = ((DataSource) ctx.lookup("jdbc/AS400")).getConnection();
        System.out.println(conn.getClientInfo());

        stmt = conn.createStatement();
        //SQL data fetch using the connection
        ResultSet rs = stmt.executeQuery("SELECT * FROM LIBRARY.TABLE");
        while (rs.next()) {
            System.out.println(rs.getString("COLUMN1"));
        }
        conn.close();
        conn = null;
    }
    catch(Exception e){System.out.println(e);}

但是,应用程序的另一部分使用了数据队列(来自同一个 jt400 库):

    String queue = "/QSYS.LIB/" + libraryName +".LIB/" + queueName +".DTAQ";

    try{
        system = new AS400(server, user, pass);
        DataQueue dq = new DataQueue(system, queue);

        // Convert the Data Strings to IBM format
        byte[] byteData = message.getBytes("IBM285");

        dq.write(byteData);
        System.out.println("Wrote to DataQueue");

    }catch(Exception e){
        e.printStackTrace();
        System.err.println(e);
    }finally{
        // Make sure to disconnect
        if(system != null){
            try{
                system.disconnectAllServices();
                System.out.println("Disconnected from DataQueue.");
            }catch(Exception e){
                System.err.println(e);
            }
        }
    }

DataQueues 引用的工作代码内部 server, user, pass,这并不理想。

我想利用我已经设置的 AS400 JNDI 连接,但是我看到的每个关于将 Java 连接到 DataQueues 的示例都引用了一个与此非常相似的示例。

documentation all seem to point to AS400 系统对象,它们是对服务器名称、用户、密码等的硬编码引用

是否有更好的方法将 DataQueue() 与 JNDI 引用结合使用?

正如上面评论中所假设的那样,DataQueue is not part of the JDBC connection at all, it can't be used to configure the connection for usage to reading and writing to a DataQueue. Since this is the case, it can't also share connection methods that JDBC uses even though the jt400 library connects with JDBC. A properties file or other server-based solutions is required unless a hard-coded connection is specified in the DataQueue/Java examples online(全部 1 个)。
