Re: Target servlet called getWriter(), then getOutputStream()

Tue, 13 Sep 2005 14:30:38 -0700 

getContent.do return null
Here is the stack after a click on the link that open the popup, what is the meaning of href="#" ? Is it reloading the current page? Because getContent.do returns null however I found reference to tile, tags in the stack?

Xavier,

Does getContent.do return anything?  I ask because your error was shown to
be JSP level, not servlet level.  Are you returning 'null' from your action
or do you invoke a forward to go to a JSP .... after .... you have closed
your output stream with  os.close() ?  At that point I expect you to return
null instead of an actionForward.

Regards,
David

The problem occurs after a click on this link :
<html:link href="#"
onclick="window.open('getContent.do?searchid=${id}&childrentype=FOO');"
styleId="simplelink">
But also if I manually call the action on a new browser tab.

The getContent.do write a datahandler to the stream :
response.setContentType(mimetype);
                 OutputStream os = response.getOutputStream();
                 tosend.writeTo(os);
                 os.flush();
                 os.close();

Remember my first mail, the problems occurs only after calling an other
action like that :
<html:form action="/updateContent.do" method="post"
enctype="multipart/form-data">
           <bean:message key="updatecontent" /> <html:file
property="contentfile"/>
           <html:hidden property="root" value="${id}"/>
           <html:hidden property="type" value="METADATA"/>
       <html:submit/>
       </html:form>

And the updatecontent action look like that (I remove all my business
logic):

                       request.setAttribute(Constants.Result,array);
                       return mapping.findForward("successthumb");
So no getstream in this action.

Why do you write that your Struts Action is the place that your code is
printing the raw file yet your stack trace shows you are in a JSP?  Is your
JSP invoking an action?  If so that's your problem: everything is probably
already committed, Stream-wise that is.  How are you getting to this action
code you included from a JSP?    Shouldn't JSP's and taglibs only use the
Writer?  Mixing that by calling some sort of action to get OutputStream
doesn't sound like a good idea, at least not according to the Tomcat

   


Servlet

 


docs on interface ServletResponse method getOutputStream() and getWriter():
Either this method or getWriter() may be called to write the body, not

   


both.

Any idea?

I have a jsp page with 3links :
- One open a popup and write a file in this popup
- One to display some text informations on the same page
- One to upload a file to the server (in fact the file displayed in
the first link)

The three link seems to work well however when I upload a new file
(the new file is successfully uploaded) but after that the two others
links are broken

The instruction that produced the stack trace is on the struts action
that write the file :

               response.setContentType(mimetype);
               OutputStream os = response.getOutputStream();    //
<---- This line generates the stack
               tosend.writeTo(os);
               os.flush();

I dont know why because I can call several time the method and it
works well, the problem only occurs after an upload of a new file
