Request.getparameter returns null in jsp

[Lukman Jaji]

Hi all

I have a multipart request connection which i have created thus...

                    MultipartRequest request = new MultipartRequest();
                    request.setUrl(AppConstants.SAVE_URL);
                    request.setPost(true);
                    request.addArgumentNoEncoding("entry_name", entry.trim());
                    request.addData("entry", dir + sep + "sent" + sep + "sent.jaji", "jaji");
                    request.setFilename("content", "sent.jaji");
                    InfiniteProgress inf = new InfiniteProgress();            
                    Dialog progress = inf.showInifiniteBlocking();
                    request.setDisposeOnCompletion(progress);
                    NetworkManager.getInstance().addToQueue(request);

On my server side

<%
    String entry_name = request.getParameter("entry_name");
    System.out.println("entry name is  "+entry_name);
%>

The entry name is always null.... I checked the network monitor and here is what it has

-15135fd3821

Content-Disposition: form-data; name="entry_name"

Content-Type: text/plain; charset=UTF-8

Nigeria_Data

--15135fd3821

Content-Disposition: form-data; name="entry"; filename="entry"

Content-Type: jaji

The result i expect should be Nigeria_Data but I get null instead. Kindly assist.

Hi,
not sure what sep is. Multipart already handles the separator of entries.
Why are you using the no encoding variant of the add argument?

[Lukman Jaji]

Hi Shai

sep is the device separator...

I used addArgumentNoEncoding() because even the regular addArgument() still gave the null result. I had thought the encoding was a problem.

However, my server side cos i getting only the entry_name and sep shouldn't be a problem.? I stand to be corrected.

Hi,
do you mean the multi-part separator?
That's already encoded into the multipart request code so having your own separator would conflict with that.

Hi Shai

I think I found the problem and it has nothing to do with the separator because I commented out the code for adding files or data to the request. I just passed an argument to the request and I still get null on the server side.

On the other hand, if I changed to ConnectionRequest, i get the correct value on the server side.

                    MultipartRequest request = new MultipartRequest();
                    request.setUrl(AppConstants.SAVE_URL);
                    request.setPost(true);

                    request.addArgument("entry_name", entry.trim());

                    InfiniteProgress inf = new InfiniteProgress();            
                    Dialog progress = inf.showInifiniteBlocking(); 
                    request.setDisposeOnCompletion(progress);
                    NetworkManager.getInstance().addToQueue(request);

This still does not work but if I changed to ConnectionRequest, it works perfect.

What could be wrong?

Hi,
if this works it means your server code isn't a multipart server. You need to fix the server.
I'm not familiar with PHP but multipart is very different to standard post.

Hi Shai

I am using JSP and not PHP....and my server is glassfish...any tips on how to make it accept multipart requests? This is the first time I'm experiencing this..

Hi,
use a servlet. See the sample servlet here:

Thanks Shai...I got it to work even though I still used JSPs...

I used the Orielly Servlets Multipart and I am able to access parameters and attachments...

Thanks
