将JT400设置为使用端口23连接到IBM i(AS400) [英] Setting JT400 to connect to IBM i (AS400) using port 23
本文介绍了将JT400设置为使用端口23连接到IBM i(AS400)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试从Java程序连接到IBM中型(AS400)计算机，然后重设用户密码.使用Jt400.jar，我设法做到了.但是问题是，我需要将端口设置为专门使用端口23.我希望它按照tn5250的方式连接到AS400.从IBM网站此处，我知道我可以通过使用as400.connectToPort(23)来实现.
I'm trying to connect to IBM midrange (AS400) machine from my java program and then reset a user's password. Using Jt400.jar, I manage to do so. But the problem is, I need to set the port to specificly use port 23. I want it to follow tn5250 on how it connect to AS400. From the IBM website here, I knew I can do so by using as400.connectToPort(23).
令我困惑的是，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原因，从而导致我 此处.这是我的代码:
What confuses me, when I add that method, I got a java.lang.RuntimeException: java.lang.NegativeArraySizeException. I did try to search what's causing this exception which lead me to here and more explanation here. This is my code:
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);
}
}
}
这是日志文件:

那么，为什么从jt400添加一个方法会导致NegativeArraySizeException?
So, why does adding one method from jt400 causes a NegativeArraySizeException?
While looking for alternative, I found more info on the JT400 method here, then tried to use as400.connectService(). From here, I assume the service that I should be using is COMMAND and SIGNON. This is part of my code after trying this method:
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，该端口为23.但是当我使用Wireshark应用程序仔细检查时，该端口用于连接到AS400的端口不是23.如果我在任何地方做错了，请指导我.
According to the log, the port is 23. But when I double check using Wireshark apps, the port that it use to connect to AS400 is not 23. Please guide me if I'm doing a mistake anywhere.
我尝试过的其他事情，
-
在
as400.connectService()和as400.setServicePort()
- 引起与上一个相同的错误:java.lang.NegativeArraySizeException
检查端口23是否可用.使用tn5250连接到AS400.连接正常.
Check either port 23 is available to use or not. Use tn5250 to connect to AS400. The connection is ok.
设置为400.connectToPort()以使用其他端口.
Set as400.connectToPort() to use other port.
- 引起与使用端口23相同的错误.
推荐答案
connectToPort()返回Socket对象，而不是AS400对象.因此，您不能使用任何AS400类与返回的Socket对象进行交互.
connectToPort() returns a Socket object, not an AS400 object. Therefore, you can't use any AS400 classes to interact with that returned Socket object.
您可以考虑使用changePassword()，而不是尝试将命令塞入telnet端口.
You might consider changePassword() instead of trying to stuff commands down the telnet port.
changePassword
public void changePassword(java.lang.String oldPassword,
java.lang.String newPassword)
throws AS400SecurityException,
java.io.IOException
Changes the user profile password. The system name and user profile name need to be set prior to calling this method.
Parameters:
oldPassword - The old user profile password.
newPassword - The new user profile password.
Throws:
AS400SecurityException - If a security or authority error occurs.
java.io.IOException - If an error occurs while communicating with the system.
