File Upload Help
I am trying to do FileUpload from the client machine to the Server, here
is the JSP form that accepts the File
<html:form action="/action/createlist" enctype="multipart/formdata">
..........
</html:form>
In the struts-config.xml i have the following things
In the form-beans section
<form-bean name="createlistForm"
type="cee.GEST.webapp.CreateListForm" >
</form-bean>
In the global Forwards section
<forward name="createlist" path="/list/createlist.jsp" />
In the action mappings section i have
<action path="/action/createlist"
type="cee.GEST.webapp.CreateListAction"
name="createlistForm"
scope="request"
input="/list/createlist.jsp">
</action>
In the Action class i have the following code
public class CreateListAction extends Action{
private Log log =
LogFactory.getLog("cee.GEST.webapp.action.CreateNewListAction");
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
FileUpload fileupload = new FileUpload();
log.info(" Created File upload object");
List fileItems = fileupload.parseRequest(request);
log.info("got the list of files");
Iterator i = fileItems.iterator();
log.info("obtained an iterator");
FileItem fileitem = (FileItem)i.next();
log.info("Create a New File Item");
String fileName = fileitem.getName();
log.info("Got the filename and trying to Write to Server");
fileitem.write("/var/www/uploads/"+fileName);
log.info("successfully wrote to the Server");
return(mapping.findForward("showmessages"));
}
}
It looks like the mapping is not the problem but the problem is with JSPs
enctype being multipart/formdata.... and when i submit the JSP the JSP
needs to invoke a POST method and i am not sure what the struts action
class does but i get this error:
No action instance for path /action/createlist could be created
description The server encountered an internal error (No action instance
for path /action/createlist could be created) that prevented it from
fulfilling this request.
Please help me out with this problem....
Thanx in advance

I believe this will only work if you are using a servlet directly,
though I could be very very wrong.
We just use the struts wrappers for the Commons-fileupload.
See the struts-upload example code.

Thank you all guyz i have found the struts-upload.war file in there and i
am trying to read that now but my question is why is it not even
recognizing the Action class, it shud atleast reach the action class and
then give an error but it is saying cannot find an instance of that action
class....do i need any other configuration for file upload to work?????

Have you tried to step thru the struts-upload example?
It is quite a comprehensive learning resource.
