[S2] ClientAbortException in StreamResult
Hello!
I've got a Action to download documents stored in a BLOB ind an oracle-db:
action name=DownloadDocumentAction method=downloadDocument
class=com.foo.FileAction
result type=stream
inputStream
/result
/action
public String downloadDocument()
{
inputStream_ = downloadFromDB(...);
return success;
}
public InputStream getInputStream()
{
return inputStream_;
}
This works as ecpected when donwloading with one thread.
When I use a download manager like DownThemAll in FF using more than one
thread, I get a ClientAbortException in StreamResult when the document is
written to the response-output. (File StreamResult.java line 265).
The first thread is processed correctly but all subsequent threads get the
exception.
Why do I get this exception?
Every thread calls the action, gets the file from the database and then the
file is written to to output.
By the way:
Is it possible to cache the file?
It's not very clever to get the file from the database for every thread...
Thanks for your help!

Re: ClientAbortException
Sorry, for my unlcear question. Actually it was a part of my question which I posted earlier. I am writing a struts appliction to download a file that is on the server. When the user clicks the download button, its displaying the open,save cancel window. Everything is working fine for files of small sizes ie. less than 50 kb..but if the file size is more and when I click cancel its displaying a ClientAbort Exception. The Exception is.. ClientAbortException: java.net.SocketException: Connection reset by peer: socket write error Oct 9, 2006 11:08:25 AM org.apache.struts.action .RequestProcessor processException WARNING: Unhandled Exception thrown: class org.apache.catalina.connector.ClientAbortException Even I am trying to catch this exception by adding ClientAbortException,(which I got it by adding the catalina jar file from tomcat/server directory to my eclipse lib folder) but still I am getting the above exception.

Re: ClientAbortException..urgent
That's not really specific to file size, or even Java in general. The root of this exception stems from the lifecycle of an http request. When a browser makes a request, the connection is maintained until the server completes the bytes it told the browser it was going to send. If you hit stop on *any* request before it is finished, you may or may not see this exception in the logs. To summarize, I wouldn't worry too much about this, there's nothing you can do to prevent it, that's just one of the quirks with web servers and clients. -- James Mitchell 678.910.8017 On Oct 10, 2006, at 1:49 AM, B.Sridhar wrote: Hi I am writing a struts appliction to download a file that is on the server.

RE: ClientAbortException
Have you tried catching the exception in the Action that's downloading the file? A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in email?
