Hi Sascha;
This is my class overview; for u to get a rough idea. Initially I have a
char array which I have converted into InputSource. Then within the Driver
class in render method I want that InputSource to be converted back into a
char array.
My class
----------------------------------------------------------------------------
--------------------------
private char[] fo;
CharArrayWriter fos = new CharArrayWriter();
fo =fos.toCharArray();
--------------------------
public void myMethod_1 (){
InputSource foSource = new InputSource(new CharArrayReader(fo));
Driver driver = new Driver();
driver.render(xmlReader, foSource);
........
........
}
FOP
----------------------------------------------------------------------------
---------------------------
Driver Class
public synchronized void render(XMLReader parser, InputSource source)
throws FOPException {
if (source.getCharacterStream() != null) {
BufferedReader reader = new
BufferedReader(source.getCharacterStream());
CharArrayWriter writer=new CharArrayWriter();
int i=-1;
while ((i=reader.read())!=-1)
{
writer.write(i);
}
reader.close();
writer.close();
}
----------------------------------------------------------------------------
------------
Thanx
Harshini.

Subject: RE: Convert InputSource into a Character array
Hi Harshini,
I though you were using a large XML String (/Character-Array) with a
CharArrayReader to setup your InputSource. Maybe I was wrong? How do you
create your input source? It seems that "someone" uses and closes the
InputSource (i.e. the stream) before FOP is invoked? Things are still a bit
unclear for me. ;-) Could you please tell me, what you are doing before FOP
is invoked and what is done afterwards?
Cheers,
Sascha
