http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18233 CoyoteOuputStream throws exception when closing Summary: CoyoteOuputStream throws exception when closing Product: Tomcat 4 Version: 4.1.18 Platform: All OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Connector:Coyote HTTP/1.1 AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Whilst printing a String to the ServletOuputStream, if the user presses the 'stop' button on their browser then an IOException is thrown. It is standard practice to try and close resources when an error occurs but when I try to close the stream I get another IOException (Connection reset by peer) because the close() method is trying to flush the stream. Now, either it is standard practice to not call close() or to ignore the exception but either of these means that the client is not confident that all the resources around the stream were cleaned up. I consider this a usability bug and possibly a functional bug, I don't really have time to investigate in the code any further to see whether the stream not being cleaned up causes any problems. Below is the stack trace that is thrown when trying to call close() on the ServletOuputStream using Tomcat 4.1.18, Java 1.4.1_02 under Windows 2K SP3: java.net.SocketException: Connection reset by peer: socket write error at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.coyote.http11.InternalOutputBuffer$OutputStreamOutputBuffer.doWrite (InternalOutputBuffer.java:668) at org.apache.coyote.http11.filters.ChunkedOutputFilter.doWrite (ChunkedOutputFilter.java:166) at org.apache.coyote.http11.InternalOutputBuffer.doWrite (InternalOutputBuffer.java:523) at org.apache.coyote.Response.doWrite(Response.java:524) at org.apache.coyote.tomcat4.OutputBuffer.realWriteBytes (OutputBuffer.java:384) at org.apache.tomcat.util.buf.ByteChunk.flushBuffer(ByteChunk.java:360) at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:338) at org.apache.tomcat.util.buf.IntermediateOutputStream.write (C2BConverter.java:273) at sun.nio.cs.StreamEncoder$CharsetSE.writeBytes(StreamEncoder.java:334) at sun.nio.cs.StreamEncoder$CharsetSE.implFlushBuffer (StreamEncoder.java:402) at sun.nio.cs.StreamEncoder$CharsetSE.implFlush(StreamEncoder.java:406) at sun.nio.cs.StreamEncoder.flush(StreamEncoder.java:150) at java.io.OutputStreamWriter.flush(OutputStreamWriter.java:213) at org.apache.tomcat.util.buf.WriteConvertor.flush (C2BConverter.java:222) at org.apache.tomcat.util.buf.C2BConverter.flushBuffer (C2BConverter.java:165) at org.apache.coyote.tomcat4.OutputBuffer.realWriteChars (OutputBuffer.java:580) at org.apache.tomcat.util.buf.CharChunk.flushBuffer(CharChunk.java:388) at org.apache.coyote.tomcat4.OutputBuffer.close(OutputBuffer.java:313) at org.apache.coyote.tomcat4.CoyoteOutputStream.close (CoyoteOutputStream.java:125) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
