Hi!

How can I read what I just wrote to a ServletOutputStream?

How can I read what I just wrote to a ServletOutputStream?

Or, in other word, why does the following snipped print
"??????????????????????????????" to my browser and what about binary data:

Reader rr = new StringReader( resp.getWriter().toString() );
Writer w = resp.getWriter();
for( int c = -1; rr.read() != -1; ) w.write( c );

Subclass it and have your methods keep a copy.

Typically that is done with a subclass of HttpServletResponseWrapper

 

[Tor Iver Wilhelmsen]

for( int c = -1; rr.read() != -1; ) w.write( c );

This writes a -1 for each character read. Are you sure you don't want
to assign to c?

for( int c = -1; (c = rr.read()) != -1; ) w.write( c );

Good point But this doesn't solve the problem anyway.

for( int c = -1; (c = rr.read()) != -1; ) w.write( c );

He wouldn't want to do that, would he? That would blow the increment variable
used in the for loop.
