JSP - Writing to XML File

I am in the process of converting ASP code to JSP, Java.
There are so many Java classes to write to a file. At the present time I want to write XML to a file but which Java class should I use and how do I proceed?

The following is ASP code.
<%

QUOT = Chr(34)
CRLF = VbCrlf

Response.ContentType = "text/xml"

'create new file, overwriting any existing one
Set objFile = objFSO.CreateTextFile(strFileName, True)

'write XML page headings to file
strLine = "<?xml version=" & QUOT & "1.0" & QUOT & " ?>"
objFile.WriteLine strLine & CRLF

strLine ="<AccessRequest xml:lang=" & QUOT & "en-US" & QUOT & ">"
objFile.WriteLine strLine & CRLF

strLine = " <AccessLicenseNumber>" & logLicense & "</AccessLicenseNumber>"
objFile.WriteLine strLine & CRLF

strLine = " <UserId>" & logUserId & "</UserId>"
objFile.WriteLine strLine & CRLF

strLine = " <Password>" & logUserPassword & "</Password>"
objFile.WriteLine strLine & CRLF

strLine = "</AccessRequest>"
objFile.WriteLine strLine & CRLF

%>
********************************************
The following JSP code creates the file. What should I do next?

<%!
void WriteXMLTransHeader1()
{

String strPathInfo = request.getServletPath();
String strRealPath = getServletConfig().getServletContext ().getRealPath(strPathInfo);
int intSlashIndex = strRealPath.lastIndexOf("\\");
String strNewRealPath = strRealPath.substring(0, intSlashIndex + 1);
String strDirectory = strNewRealPath + "UPSTrans";
String strFileName = "Order" + logOrderId + "A" + ".xml";

File f1 = new File(strDirectory, strFileName);

f1.createNewFile();
System.out.println("File: Order" + strFileName + "created");

%>

Thanks for your help,

As you may or may not know, there are tons of Streams you can use for i/o in java. Sometimes that can seem daunting. What you want to use is a FileOutputStream or a FileWriter. There are minor differences between them and either should work. There is a BufferedOutputStream that buffers output so that writing to the hard drive is done in a more efficient manner. There is also a PrintStream for easy formatting of output.

The nice thing about Streams is that they can be wrapped. So, you could make a FileOutputStream and wrap it in a BufferedOutputStream, and then wrap THAT in a PrintStream. This gives you the benefits of all. Here is an example I found on Suns site:


This example has the files name in a string for the FileOutputStreams constructor, but you can give it File object also. You should be able to use this with minor modifications.
