publicId 和 systemId 之间需要空格

我试图通过在 jsp 中编写一些代理代码来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
        });
    };

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() %>

当我检查响应时，我收到它正在解析的 XML 文件的错误：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>

XMl 文件是这样的：-

我在这里做错了什么.. 任何建议将不胜感激..

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.

 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:-

<%@ 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:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 White spaces are required between publicId and systemId.</title>

该错误消息即使不明显，实际上也是正确的。它表示您的 DOCTYPE 必须有一个 SYSTEM 标识符。我假设你的只有一个公共标识符。

你会得到错误（例如）：

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

你不会：

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">

注意第二个末尾的 "" -- 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，而不是您需要在 publicId 和（不存在的）systemId 之间留一个空格。

顺便说一句，空的系统标识符可能并不理想，但它可能足以让您前进。

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.

You'll get the error with (for instance):

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

You won't with:

<!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.

By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.

我刚刚发现自己遇到了这个异常，我试图使用 JAX-WS，具有如下所示的自定义 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);

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.

事实证明，用于构造服务的 URL 字符串缺少“？wsdl”结尾。
例如：

不好：

http://www.host.org/service/Customer

好：

http://www.host.org/service/Customer?wsdl

I just found my self with this Exception, I was trying to consume a JAX-WS, with a custom URL like this:

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:

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:

Bad:

http://www.host.org/service/Customer

Good:

http://www.host.org/service/Customer?wsdl

更改语句的顺序。
块

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/beans/spring-beans.xsd"

对我来说，更改代码

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/context"

是有效的。

Change the order of statments.
For me, changing the block of code

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/beans/spring-beans.xsd"

with

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/context"

is valid.

它可能与打开标题的人的错误无关，但我想分享它，因为它与标题相同的错误。

这是我在使用 Netbeans 和 Maven 在 glassfish 服务器上运行 jsf primeface 时遇到的一个错误。

这就是让我失败的方式：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

但我这样返回并没有收到任何错误：

<!DOCTYPE html>

It may not be related to the mistake of the person who opened the title, but I wanted to share it because it is the same error as the title.

It was an error I got in one of my runs jsf primeface on glassfish server with netbeans and maven.

This was the way of give me fail:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

But I returned this way and I didn't get any error:

<!DOCTYPE html>

如果您使用的某个网络需要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，并将代理配置添加到网络设置中解决了它。

  • 转到您的首选项（在 Mac 上为 Eclipse -> Preferences，在 Windows 上为 Window -> Preferences）
  • 然后 ->一般->展开查看下面的列表 ->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”。
  • 然后在下拉菜单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。
  • 在网络浏览器中输入正常连接互联网所需的代理 URL 和端口。
  • 对“HTTPS”重复上述操作。

如果您不知道代理 URL 和端口，请与您的网络管理员联系。

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.

  • 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."

If you don't know the proxy url and port, talk to your network admin.
