Prevent xml escaping in Restful (JAXRS)

I have a restful service(jersey) that returns a url with request parameters in one of the tags. Example :
<url>http://abc:9080/testMe.jsp?req1=a&req2=b</url>
(It's part of the response)
When I get the response, I get as below ('&' becomes '& a m p;', without any space. I added space to avoid escaping here):
<url>http://abc:9080/testMe.jsp?req1=a&req2=b</url>
I looked up in google and found many ways to do it in jaxb but nothing in Restful (JAXRS). Also, I tried a lame solution of adding backslash but with no success.
How can I prevent it from happening in java 1.6?

There is nothing you should change, since this is like XML works: & is a special character in XML and any & contained in text is escaped as &
Your expected result ...=a&req2=b... would not be a well-formed XML document, whereas the result returned by Jersey is well-formed.
When you want to access the url value in the response document, you will need to parse the response with a XML parser (e.g. into a DOM document) and the parsed document will have the url value as you expect.

XML format received is not well formed?? why?

I am trying to write a ASP.net Web API that sends XML files from the database and recieve/read it on android
The XML file that I send is something like this
<ArrayOfMerchant xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/MvcApplication1.Models">
<Merchant>
<Address>ABC</Address>
<City>HHHH</City>
<Country>EEEE</Country>
<Id>1</Id>
<Latitude/>
<Longitude/>
<Name>Some store</Name>
</Merchant>
</ArrayOfMerchant>
Opened on browser and it looks fine.
On the Android side I am trying to receive and read it with HttpURLConnection.
Everything works , but when I try to convert the Input-stream into string, the string is something like
String = [{"Id":1,"Name":"Some store","Address":"ABC","City:"EEEE","Country":"Canada","Longitude":"","Latitude":""}]
Question:
1)Why does it display differently with different markup and also different ordering of the elements?
2)How can I receive / retrieve it as a normal XML file so I can parse it?

1) I dot know, depends on your ASP code and configuration. You can try to change parameters of your HTTP request to see how your ASP app respond when you change Accept header or User-Agent. There are some tools.
2) Actually, you don't need XML to parse the data .

Array Serialization in Axis

I have encountered a strange problem when calling a web service. My stubs generate soap message like in format 2 however server expects something like in format 1 below.
In arrayserialization in axis 1.3 what is the meaning of following formats.
Below arrayItemType is Object type whics is being serialized and arrayItemName is the name of that object.
1)
<arrayItemName>
<arrayItemType></arrayItemType>
<arrayItemType></arrayItemType>
</arrayItemName>
2)
<arrayItemName>
</arrayItemName>
<arrayItemName>
</arrayItemName>

The question what style is your WSDL file? SOAP document depends on style used in WSDL file.
The first format is wrapped style, because elements is wrapped within:
<arrayItemName> ... </arrayItemName>
So I guess that if your stubs generates soap message like in format 2 it uses rpc/encoded or any other WSDL styles except the wrapped one. So I suggest you always use document/literal wrapped style for wsdl files and there will be any problems when generating clients using different stacks or etc.
You can find useful information about WSDL styles here: http://www.ibm.com/developerworks/webservices/library/ws-whichwsdl/

Selenium 2: Detect content type of link destinations

I am using the Selenium 2 Java API to interact with web pages. My question is: How can i detect the content type of link destinations?
Basically, this is the background: Before clicking a link, i want to be sure that the response is an HTML file. If not, i need to handle it in another way. So, let's say there is a download link for a PDF file. The application should directly read the contents of that URL instead of opening it in the browser.
The goal is to have an application which automatically knows wheather the current location is an HTML, PDF, XML or whatever to use appropriate parsers to extract useful information out of the documents.
Update
Added bounty: Will reward it to the best solution which allows me to get the content type of a given URL.

As Jochen suggests, the way to get the Content-type without also downloading the content is HTTP HEAD, and the selenium webdrivers does not seem to offer functionality like that. You'll have to find another library to help you with fetching the content type of an url.
A Java library that can do this is Apache HttpComponents, especially HttpClient.
(The following code is untested)
HttpClient httpclient = new DefaultHttpClient();
HttpHead httphead = new HttpHead("http://foo/bar");
HttpResponse response = httpclient.execute(httphead);
BasicHeader contenttypeheader = response.getFirstHeader("Content-Type");
System.out.println(contenttypeheader);
The project publishes JavaDoc for HttpClient, the documentation for the HttpClient interface contains a nice example.

You can figure out the content type will processing the data coming in.
Not sure why you need to figure this out first.
If so, use the HEAD method and look at the Content-Type header.

You can retrieve all the URLs from the DOM, and then parse the last few characters of each URL (using a java regex) to determine the link type.
You can parse characters proceeding the last dot. For example, in the url http://yoursite.com/whatever/test.pdf, extract the pdf, and enforce your test logic accordingly.
Am I oversimplifying your problem?

how to use XML sent by html form?

i have html form with textarea in which i paste some XML, for example:
<network ip_addr="10.0.0.0/8" save_ip="true">
<subnet interf_used="200" name="lan1" />
<subnet interf_used="254" name="lan2" />
</network>
When user submit form, that data is send to Java server, so in headers i get something like that:
GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E HTTP/1.1
how can i use that in my Java applications? I need to make some calculations on that data and re-send new generated XML.

This answer shows how to use the URLDecoder/URLEncoder classes to decode and encode url strings. It should work if you passed the 'GET' string to the URLDecoders decode method.
To answer your following question (comment)
First you need to extract this xml based response from the url string. Maybe it's enough to create a substring starting with the first < char.
The String should be fed into a XML parser to create a DOM document. The last easy task would be walking through that document and copying the values to your internal network model.
Do not think about using RegExp to extract the data. Use a parser.
