我试图从我的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网站在这里，我知道我可以利用这样做as400.connectToPort(23)。

令我感到困惑的是，当我添加该方法时，我得到了一个java.lang.RuntimeException: java.lang.NegativeArraySizeException。我曾尝试寻找什么导致此异常导致我在这里和更多的解释在这里。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 …

我正在尝试将木偶大师的文件复制到木偶代理中.用它来安装.然后删除该文件.我已经测试了脚本,直到安装部分,它工作正常.唯一的问题是删除文件时.添加几行后,我收到此错误.

Error: Failed to apply catalog: Duplicate declaration: File[/home/mypackage-4.4.0.rpm] is already declared in file /etc/puppet/manifests/site.pp:23; cannot redeclare at /etc/puppet/manifests/site.pp:31

这是我写的pp文件:

class mypackage {
    $version = '4.6.0'
    if $::operatingsystem == 'CentOS' {
            exec { "mypackage-uninstall":
                    path    => ['/usr/bin','/usr/sbin/','/bin','/sbin'],
                    command => "/bin/rpm -e mypackage",
            }
            file { "mypackage-${version}.rpm":
                    path    =>"/home/mypackage-${version}.rpm",
                    source  => "puppet:///modules/mypackage-${version}.rpm"
            }
            exec { "mypackage-install":
                    path    => ['/usr/bin','/usr/sbin','/bin','/sbin'],
