Jdom dom4j Parsing XML does not validate DTD doctype

First, write in all before:
Because Dom4j and jdom on this issue is the same way to deal with, but one is Saxbuilder a saxreader, here to jdom distance, as for the dom4j only need to replace the same.
Ii. situation in which the problem occurred
When you read a DTD-validated XML file with Jdom, your network is not available. The following error occurs:
1, the code is as follows
Package DOM;

Import Java.io.File;

Import org.jdom.Document;
Import Org.jdom.input.SAXBuilder;

public class Testjdom {
public static void Main (string[] args) {
File File = new file ("./src/dom/aiwf_aiservice.xml");
if (file.exists ()) {
Saxbuilder builder = new Saxbuilder ();
try {
Document doc = builder.build (file);
System.out.println (DOC);
catch (Exception e) {
E.printstacktrace ();
}
} else {
System.out.println ("Can not find XML file:"
+ File.getabsolutepath ());
}
}
}

2,xml document;? XML version= "1.0" encoding= "GBK"?>
<! DOCTYPE Workflow Public "-//opensymphony group//dtd osworkflow 2.8//en" "http://www.opensymphony.com/osworkflow/ Workflow_2_8.dtd ">
< Workflow >
...............
</Workflow >

3, the error is as follows Java.net.SocketException:Permission Denied:connect

Three, parsing reason
Jdom parsing to
doctype workflow public  when executing a build-/OPENSYMPHONY&NBSP;GROUP//DTD  osworkflow 2.8//en " " HTTP://WWW.OPENSYMPHONY.COM/OSWORKFLOW/WORKFLOW_2_8.DTD
will go to read http:// www.opensymphony.com/osworkflow/workflow_2_8.dtd  here the DTD file to verify, but because the network is not a pass, so will be reported socket error.

Four, workaround
