Hello,
I use Batik
(tomcat4.0.4b2,jdk1.3.1_02,ntsp6) to generate dynamic Graphics( and it is
working really fine :-) ). My Problem starts when the client breaks
loading a PNGgraphic, pressing the reload button f.e., I get the message:
<exception> StandardWrapperValve[PngJob]:
Servlet.service() for servlet PngJob threw exception
java.io.IOException: Cannot write to a closed output stream.............</exception> I found in the archieves a similar problem http://archive.covalent.net/xml/batik-dev/2001/09/0079.xml,
but in my case no Jpg's are involved.
Here is the code-snippet:
<code>
TranscoderInput input = new
TranscoderInput(strr);
PNGTranscoder t = new PNGTranscoder(); TranscoderOutput output = new TranscoderOutput(outputstr); //try
t.transcode(input, output);
//catch
outputstr.close(); </code>
Am I missing something?
