How to get the whole payload

Question

Hey guys,
I have a requirement where I need to call a stored procedure through a JDBC adapter. The particularity in this call is that I need to send the complete source XML payload as a string in just one element and not mapping each element with input variables of the store procedure.
I need to know if there is a way to get the incoming XML payload as one big String within XI.
Any inputs will be helpful !!!
Cheers,
Mauricio

Hi,
When you write a JAVA Mapping , you need to implement the StreamTransfromationClass which implements execute and setParameter methods.
In the execute method , you get the Source XML as an InputStream and the need to push the Output XML as the output stream.
You can use a DOM or SAX parser to prase the XML source and create the target XML.
To get the entire Source into s String, use this code,
BufferedReader in = new BufferedReader(new InputStreamReader(inp));
StringBuffer buffer = new StringBuffer();
String line="";
while ((line = in.readLine()) != null) {
buffer.append(line);
String sourcexml=buffer.toString();
Take a look at thise blog for Java Mapping,
