使用 IFSFileInputStream 连接到 iSeries 时出现 java.netConnectException 错误

Question

我有一个简单的 Java 程序（使用 JTOpen）连接到 iSeries 并打开 IFS 文件：

System.out.println("by ipaddress");
AS400 as400 = new AS400("130.3.3.333", "user", "password");
System.out.println("as400 connected? = " + as400.getCcsid());
//handle the exception if the file is null 
IFSFileInputStream as400File = new IFSFileInputStream(as400, "//PDF//00000104.PDF");
System.out.println("is available" + as400File.getPath());
as400File.close();

在 DMZ 中的一台服务器上一切正常，但在不同建筑物（仍在 DMZ）中的服务器上的（假定相同）VM 映像上，我收到错误：

by ipaddress
as400 connected? = 37

连接工作正常，但随后出现连接异常。

欢迎任何想法。相同的端口在两台服务器与 iSeries 之间的防火墙中打开。

Answer 1

每个端口都有多个服务，初始连接只打开一个。检查文件服务的jt400 faq。我希望在防火墙中未打开此端口。
