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（假设相同的）VM映像上，我收到错误：

by ipaddress
as400 connected? = 37
IO security exception

连接正常，但后来获得连接异常。

欢迎任何想法。在两个服务器与iSeries之间的防火墙中打开了相同的端口。

Answer 1

每个端口上都有多个服务，初始连接只打开一个。检查jt400 faq以获取文件服务。我希望这个端口在防火墙中不打开。

使用IFSFileInputStream连接到iSeries时出现java.netConnectException错误
