Isn't this slow? Why not put them on disk?

Try "unknown" as a test. If the url extension is .pdf it will load in
acrobat.

Something is getting sent prior to your setting the content type, most
likely.
You should buffer this out. Pass in the servletoutputstreem to something
like:
/////////////////////////////////////////////////////////
/**
* Stream the file since it could be huge.
*/
public static void bufferItOut( OutputStream out, String fileName ) {
//p( "serving file" );
// buffered read of file
//pBean.setContentType( "application/pdf" );
//String line = null;
try {
//byte[] file_bytes = null;
File f = new File( fileName );
final int size = (int)f.length();
//file_bytes = new byte[size];
int defBufSize = 8192;
byte[] b_buf = new byte[defBufSize];
//ServletOutputStream out = pBean.res.getOutputStream();
FileInputStream fis = new FileInputStream(f);
int totalRead = 0;
try {
if ( size < defBufSize ) {
byte[] s_buf = new byte[size - totalRead];
int read = fis.read(s_buf);
out.write( s_buf, 0, s_buf.length);
totalRead = s_buf.length;
}
else {
while ( size - totalRead > 0 ) {
if ( size - totalRead > defBufSize ) {
int read = fis.read(b_buf);
out.write( b_buf, 0, b_buf.length);
totalRead += defBufSize;
// data left is less than the buffer
} else {
byte[] s_buf = new byte[size - totalRead];
int read = fis.read(s_buf);
out.write( s_buf, 0, s_buf.length);
totalRead += s_buf.length;
}
}
}
} catch ( Exception e ) {
log.error( e );
} finally {
fis.close();
//out.close();
}
} catch( Exception e ) {
log.error( e );
}
}
