Re: Struts2 with AJAX
Hi,
In your action class you have to return null after you write the
response for eg:-
public String ajax() throws Exception {
respone.getWriter().println("hello");
respone.getWriter().close();
return null;
}
and also i dont think you need to specify the full URL when you are
doing the ajax call.,
Thanks,
Nuwan

Hi,
I am using a very basic AJAX code snippet with struts. No it's not
dojo.
req = new XMLHttpRequest();
var url='http://localhost:8084/StrutsAjax/example/SearchAJAX.action';
req.open("POST",url,true);
req.onreadystatechange=searchResults;
req.send(null);
in searchResults() function I just wnt to see req.responseText;
If I want to return some response from server side if I use something
crude like this
response.getOutputStream().print("Animesh");
It messes up struts and I get lots of exceptions in responseText.
I want to return some string from the server side which is accessible by
javascript code. It can be JSON or anything.
What should be the code on server side / my action class (execute
method) to return something to client side? Any suggestions??
Thanks,
Animesh

Re: Struts2 with AJAX file upload??
No, I don't see why you would need to. If your page is creating the proper multipart request, Struts should be able to handle it as long as the target action uses an interceptor stack that contains the file upload interceptor.

What do you mean by trying to find controller tags in struts.xml? How do you have it implemented in Struts 1?

Struts2 with AJAX file upload??
Hi guys I want to implement AJAX file upload in Struts2. tried searching over on the net, but couldn't find much. I have an AJAX based file uploader working in Struts1.x but i'm not able to migrate it to Struts2 due to some uncommon controller mappings (such as i'm not finding any conroller tags to be placed inside my struts.xml). Needed some pointers for the same. Please help. Any suggestions will be appreciated. regards, Nagraj
