downloading csv within Struts

[damien malone]

Hello
Apologies if this is not the correct forum. I have written a servlet that generates a csv file. This all works fine, but I now want to integrate this servlet into a struts web app. I have the following lines at the top of my servlet
String filename = "export.csv";
response.setContentType("application/unknown");
response.setHeader("Content-Disposition", "attachment;filename=\""+filename+"\"");

I have also tried re-writting as a jsp. and placing the setheader into the action class.
However what ever I try, when I try and access the page, the servlet and action class are run (I have system outs that are displayed) but the browser then pops up a message dialog saying unable to locate the web page I am trying to download.
Any ideas??
Thanks

Just configure your servlet in your web.xml on a different path than struts. Also struts uses a servlet as controller when you check your
web.xml. Normally it is mapped to /do/ or *.do.
So maybe a good solution would be to create the following entry:

    <servlet>
        <servlet-name>csvgenerator</servlet-name>
        <servlet-class>your.class</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>csvgenerator</servlet-name>
        <url-pattern>/genarator/*</url-pattern>
    </servlet-mapping>  

Then you can access your Servlet with
http://yourserver/yourapp/generator/
hope that helped
