White spaces are required between publicId and systemId
提问by arsenal
I am trying to make a ajax call to other domain locally from my computer by writing some proxy code in jsp. And this is my jQuery AJAX code that is calling proxy.jsp page.
我正在尝试通过在 jsp 中编写一些代理代码，从我的计算机本地对其他域进行 ajax 调用。这是我调用 proxy.jsp 页面的 jQuery AJAX 代码。
var metadata = 'https://rest-search.host.com/machine/search/meta?id=';
var on_show_info= function() {
var AjaxCall = data + current_doc_info.id;
alert(AjaxCall);
request_meta_info = $.ajax({
url: "proxy.jsp?url=" + AjaxCall,
type: 'GET',
success: check,
error: error
});
};
And my JSP file is:-
我的 JSP 文件是：-
<%@ page language="java" import="org.w3c.dom.*,javax.xml.parsers.DocumentBuilder,javax.xml.parsers.DocumentBuilderFactory,java.net.*,java.io.*" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%
String urlToQuery = request.getParameter("url");
System.out.println("rj " +urlToQuery);
URL url = new URL(urlToQuery);
final String login ="user";
final String password ="pass";
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication (login, password.toCharArray());
}
});
URLConnection conn = url.openConnection();
InputStream in = conn.getInputStream();
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db =dbf.newDocumentBuilder();
Document doc=db.parse(urlToQuery);
NodeList nl= doc.getElementsByTagName("attr");
%>
<%= nl.item(0).getFirstChild().getNodeValue() %>
And When I check the response, I am getting this error for the XML file it is parsing:
当我检查响应时，它正在解析的 XML 文件出现此错误：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>

The error message is actually correct if not obvious. It says that your DOCTYPE must have a SYSTEM identifier. I assume yours only has a public identifier.
如果不明显，错误消息实际上是正确的。它说您的 DOCTYPE 必须有一个 SYSTEM 标识符。我假设你的只有一个公共标识符。
You'll get the error with (for instance):
你会得到错误（例如）：
<!DOCTYPE persistence PUBLIC
"http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
You won't with:
你不会：
<!DOCTYPE persistence PUBLIC
"http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">
Notice ""at the end in the second one -- that's the system identifier. The error message is confusing: it should say that you need a system identifier, not that you need a space between the publicId and the (non-existent) systemId.
注意""第二个的末尾——这是系统标识符。错误消息令人困惑：它应该说您需要一个系统标识符，而不是在 publicId 和（不存在的）systemId 之间需要一个空格。
By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.
顺便说一句，空的系统标识符可能并不理想，但它可能足以让您动起来。

A couple people here had success by switching the lines around in an XML file.
这里有几个人通过切换 XML 文件中的行获得了成功。

I just found my self with this Exception, I was trying to consume a JAX-WS, with a custom URL like this:
我刚刚发现我自己遇到了这个异常，我试图使用一个 JAX-WS，一个像这样的自定义 URL：
String WSDL_URL= <get value from properties file>;
Customer service = new Customer(new URL(WSDL_URL));
ExecutePtt port = service.getExecutePt();
return port.createMantainCustomers(part);
and Java threw:
和Java抛出：
XML reader error: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,63]
Message: White spaces are required between publicId and systemId.
Turns out that the URL string used to construct the service was missing the "?wsdl" at the end. For instance:
事实证明，用于构建服务的 URL 字符串末尾缺少“?wsdl”。例如：
Bad:
坏的：
http://www.host.org/service/Customer
Good:
好的：
http://www.host.org/service/Customer?wsdl

If you're working from some network that requires you to use a proxy in your browser to connect to the internet (likely an office building), that might be it. I had the same issue and adding the proxy configs to the network settings solved it.
如果您使用的网络要求您在浏览器中使用代理来连接到互联网（可能是办公楼），那么可能就是这样。我遇到了同样的问题，将代理配置添加到网络设置中解决了它。
- Go to your preferences (Eclipse -> Preferences on a Mac, or Window -> Preferences on a Windows)
- Then -> General -> expand to view the list underneath -> Select Network Connections (don't expand)
- At the top of the page that appears there is a drop down, select "Manual."
- Then select "HTTP" in the list directly below the drop down (which now should have all it's options checked) and then click the "Edit" button to the right of the list.
- Enter in the proxy url and port you need to connect to the internet in your web browser normally.
- Repeat for "HTTPS."
- 转到您的首选项（Eclipse -> Mac 上的首选项，或 Windows -> Windows 上的首选项）
- 然后 -> 常规 -> 展开以查看下面的列表 -> 选择网络连接（不要展开）
- 在出现的页面顶部有一个下拉菜单，选择“手动”。
- 然后在下拉列表正下方的列表中选择“HTTP”（现在应该选中所有选项），然后单击列表右侧的“编辑”按钮。
- 在您的网络浏览器中输入您需要正常连接到互联网的代理网址和端口。
- 重复“HTTPS”。
If you don't know the proxy url and port, talk to your network admin.
如果您不知道代理 URL 和端口，请咨询您的网络管理员。

Change the order of statments. For me, changing the block of code
更改语句的顺序。对我来说，改变代码块
