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>

And the XMl file is this:-
<results><result><attr value="HW/SW" name="Line"/><attr value="ASIC" name="Description"/><attr value="CD" name="Number"/><attr value="AS" name="DocumentType"/><attr value="" name="Date"/><</result></results>
What wrong I am doing here.. Any suggestions will be appreciated..

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.
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.
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
I just found this post: http://forum.springsource.org/showthread.php?68949-White-spaces-are-required-between-publicId-and-systemId./page2&s=c69fe19798f5a071d22eaf681ca84a56
A couple people here had success by switching the lines around in an XML file.
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.
If you don't know the proxy url and port, talk to your network admin.
