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

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.
