> Hi,
> I'm using StreamResult to download files from an action. The thing is that
> when the connection is closed by the client, a ClientAbortException is logged
> by Tomcat, like this:

> We assume that the client aborting the download is not a reason to show an
> exception in tomcat's log, so we don't want to log it.
> (I think this "no logging" option could be implemented as another parameter
> of the stream result.)
> I researched a little the issue, and found that ClientAbortException is a
> Tomcat exception:
> http://svn.apache.org/repos/asf/tomcat/tc5.5.x/trunk/container/catalina/src/share/org/apache/catalina/connector/ClientAbortException.java
> http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk/java/org/apache/catalina/connector/ClientAbortException.java
> so we must watch out not to introduce a tomcat dependency here...maybe asking
> for
> exception.getClass().getName().equals("org.apache.catalina.connector.ClientAbortException")
> ?
> Thanks in advance,
> Gabriel
