struts2 problem when file download dialog is closed
Hi,
I've created a struts2 application that creates text file and displays the
file download dialog for the user to open or save it.
It works fine if the user opens or saves it, but if the user closes the
file download dialog the program logs the following error:
Servlet failed with Exception
java.lang.IllegalStateException: Response already committed
at
weblogic.servlet.internal.ServletResponseImpl.objectIfCommitted(Servl
etResponseImpl.java:1422)
at
weblogic.servlet.internal.ServletResponseImpl.sendError(ServletRespon

a:506)
at
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatc
her.java:395)
Truncated. see log file for complete stacktrace
>
My struts.xml file code is as follows:
<action name="AdmExport" class="ConfigAction" method="export">
<result name="success" type="stream">
<param name="contentType">application/octet-stream</param>
<param name="inputName">inputStream</param>
<param
name="contentDisposition">attachment;filename="tempExport.txt"</param>
<param name="bufferSize">1024</param>
</result>
</action>
My action class code is as follows:
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class ConfigAction extends ActionSupport implements SessionAware
{
public void setInputStream(InputStream inputStream) {
this.inputStream = inputStream;
}
public InputStream getInputStream() {
return inputStream;
}
public String export() throws Exception {
try
{
// code to create tempExport.txt file
File exportFile = new File("./tempExport.txt");
setInputStream(new FileInputStream(exportFile));
exportFile.delete();
}
catch (Exception ex)
{
ex.printStackTrace();
}
return SUCCESS;
}
}
Any ideas as how to fix the issue will be greatly appreciated.

when the dialog closes, are you still calling the action ?

RE: struts2 problem when file download dialog is closed
Posted by sv...@bnymellon.com.
Adam,
The control is out of the action class and if the user will open or save
the file, there is no problem and the control goes to the JSP page.
For some reason once the error occurs if the user clicks another button
that makes AJAX call to server, the call does not go through but instead
returns cashed results from the previous AJAX call.
Thanks,
Lana.

is the user "cancelling" still sending a request to the server and hence
you are trying to return an error - if so i'd assume the http connection
has been terminated and therefore you can't send an http response back.
if its just logged but doesn't stop user experience then leave it.

Re: struts2 problem when file download dialog is closed

Venkata,
I use Struts2 2.2.1.1 version.
I've changed the filter to StrutsPrepareAndExecute Filter.
The same error:

Muneer,
When the user closes dialog the control goes to jsp page, but the behavior
is strange as when I try subsequently to do AJAX call, it does not go to
the server, but instead uses the cashed response.
Thanks,
Lana.

You are using older version Struts2.x and change filter to
