将JT400设置为使用端口23

时间：2015-06-30 03:14:56

标签： java ibm-midrange jt400

我尝试从我的java程序连接到IBM midrange（AS400）计算机，然后重置用户的密码。使用Jt400.jar，我设法这样做。但问题是，我需要将端口设置为特定使用端口23.我希望它遵循tn5250如何连接到AS400。从IBM网站here，我知道我可以使用as400.connectToPort(23)。

让我感到困惑的是，当我添加该方法时，我得到了java.lang.RuntimeException: java.lang.NegativeArraySizeException。我确实尝试搜索导致此异常的内容，这导致我here和更多解释here。这是我的代码：

public void executeSetPassword(final String userName, final GuardedString password)  {

    if ((userName != null) && (password != null)) {
        final String host = configuration.getHost();
        final String remoteUser = configuration.getRemoteUser();
        GuardedString passwd = configuration.getPassword();
        boolean isSuccessful;

        final AS400 as400 = new AS400();

        try {
            as400.setSystemName(host);
            as400.setUserId(remoteUser);

            passwd.access(new Accessor(){
                @Override
                public void access(char[] clearChars) {
                    try {
                        as400.setPassword(new String(clearChars));
                    }catch (Exception e) {
                        e.printStackTrace();
                    }
                }});

            as400.setGuiAvailable(false);
            as400.connectToPort(23);

            final CommandCall cc = new CommandCall(as400);
            final StringBuilder command = new StringBuilder();
            password.access(new Accessor(){
                    @Override
                    public void access(char[] clearChars) {
                            command.append("CHGUSRPRF USRPRF(" + userName + ") PASSWORD(" + new String(clearChars) + ")");
                    }});
            try {
                isSuccessful = cc.run(command.toString());


                logger.info("command status is = " + isSuccessful);
                // getMessageList returns an array of AS400Message objects
                for(AS400Message msg : cc.getMessageList()){
                    logger.info(
                            "  msg: " + msg.getID() + ": " + msg.getText());
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        } catch (Exception e){
            throw new RuntimeException(e);
        }
    }
}

那么，为什么从jt400添加一个方法会导致NegativeArraySizeException？

在寻找替代方案时，我发现有关JT400方法here的更多信息，然后尝试使用as400.connectService()。从here开始，我假设我应该使用的服务是COMMAND和SIGNON。尝试此方法后，这是我的代码的一部分：

final AS400 as400 = new AS400();                
        try {

            as400.setSystemName(host);
            as400.setUserId(remoteUser);
            passwd.access(new Accessor(){
                @Override
                public void access(char[] clearChars) {
                    try {
                        as400.setPassword(new String(clearChars));
                    }catch (Exception e) {
                        e.printStackTrace();
                    }
                }});
            as400.setGuiAvailable(false);

            as400.connectService(7);      //I added this
            as400.setServicePort(7, 23);  //I added this
            as400.setServicePort(6, 23);  //I added this
            logger.info("port is = " + as400.getServicePort(7));
            final CommandCall cc = new CommandCall(as400);
            final StringBuilder command = new StringBuilder();
            password.access(new Accessor(){
                    @Override
                    public void access(char[] clearChars) {
                            command.append("CHGUSRPRF USRPRF(" + userName + ") PASSWORD(" + new String(clearChars) + ")");
                    }});
            try {

                isSuccessful = cc.run(command.toString());
                as400.setServicePort(2, 23); //I added this
                logger.info("port is = " + as400.getServicePort(2));
}

根据日志，端口是23.但是当我使用Wireshark应用程序仔细检查时，用于连接AS400的端口不是23.请指导我，如果我在任何地方都犯了错误。< / p>

我尝试过的其他事情，

  1. 在as400.connectService()和as400.setServicePort()

    之间切换行
    • 导致与前一个错误相同的错误：java.lang.NegativeArraySizeException

  2. 检查端口23是否可以使用。使用tn5250连接到AS400。连接正常。

  3. 设置as400.connectToPort（）以使用其他端口。

    • 导致与使用端口23相同的错误。

1 个答案:

答案 0 :(得分：5)

connectToPort（）返回一个Socket对象，而不是AS400对象。因此，您无法使用任何AS400类与返回的Socket对象进行交互。

您可能会考虑使用changePassword（）而不是尝试将命令填入telnet端口。
