Downloading the string as an XML file

Question

I tried to download a string stored in session to be downloaded as a XML file. I am able to download the file. But the problum I am getting space at the top of the file
The code I used is like
<%
String xmlContent = xmlContent.trim();
     SAXBuilder builder = new SAXBuilder();
     Document doc = builder.build(new ByteArrayInputStream(xmlContent.getBytes()));
     XMLOutputter outputter = new XMLOutputter(Format.getPrettyFormat());
     //response.setContentType("APPLICATION/XML");
     response.setContentType( "application/xml" );
     response.setHeader("Content-Disposition","attachment; filename=\""+ fileName+"" + "\""+"");
     try{
          //outputter.output(doc,System.out);
          outputter.output(doc,out);
          //outputter.o
     catch(Exception e){
          System.out.println("Exception while displaying config request data "+ e);
%>
the output has spaces above the xml prolog. Can anybody help me in solving this issue.
Thank you.

Answer 1

I have designed an application that uses XML
as the storage instead of database.Ok.
I think searching for a particular element in an XML
file is complex, and other than that I am not seeing
any problem.You could abstract that complexity away behind an Adapter.
So I need u guys view points on this
"usage of data in an XML file".It depends on the nature and format of that to determine if it's a good idea. You need to consider a number of factors when deciding how to persist data. How much data is there, how often does the format and/or semantics of that data change, how is the data presented or processed. What is the lifetime of that data, what is the ratio of writes to reads. what is the access scope of the data, how secure does the data need to be.
Finding the most appropriate format for data is oten more important than finding the most appropriate algorithm for a program, since data often has a longer life time that the programs that access it.
