Question

I have used the following java code to POST xml data to a remote url and get the response. Here, I am using an xml file as the input. What I need is to pass the xml as a string

Answer 1

You can convert the XML to String from this method

public String convertXMLFileToString(String fileName) 
{ 
   try{ 
       DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
       InputStream inputStream = new FileInputStream(new File(fileName)); 
       org.w3c.dom.Document doc = documentBuilderFactory.newDocumentBuilder().parse(inputStream); 
       StringWriter stw = new StringWriter(); 
       Transformer serializer = TransformerFactory.newInstance().newTransformer(); 
       serializer.transform(new DOMSource(doc), new StreamResult(stw)); 
       return stw.toString(); 
   } 
   catch (Exception e) { 
       e.printStackTrace(); 
   } 
   return null; 
}

Add you can pass this string as a parameter on PostMethod like this.

PostMethod post = new PostMethod(strURL);
post.addParamter("paramName", convertXMLFileToString(strXMLFilename ) );

The whole XML will be transmitted to the client in a queryString.
