Getting session attributes from multipart/form-data form

[Ramesh kangamuthu]

Hi,
I have been doing a web application related on online shopping. It has file uploading capability.In some forms,I used enctype="multipart/form-data" for the forms. I set some session attributes in the jsps,in which I put enctype as multipart/form-data for the forms. If I tried to get the session attributes in servlets, I got null. How can I retrieve session and other types of attributes from jsps?

Can anyone give me the answer?

Best regards,

I think you're either confusing terms or misinterpreting the problem you're seeing.

I don't think the problem is with the adding or retrieving of variables to or from session. It's most likely that you're not getting the parameters properly. When you respond to multipart requests in your servlets or JSPs, request.getParameter doesn't work. It will always return null.
To retrive your form parameters, you'll need to check the documentation for the upload libraries that you're using.

Thanks Ben,

I understood the problem clearly. In multipart request request.getParameter() does not work,I knew. Also I got those type of parameters after checking FileItem's isFormField() method and

fileItemObject.getName()

fileItemObject.getString() methods. No problem.

My problem is how I can get session attributes set in a jsp,that has multipart/form-data form. I tried for the multipart form and got the session attribute as null. If the request is not multipart, result comes.

If I tried the following

NewsList newsList=(NewsList)request.getSession().getAttribute("newsList");

I got the newsList Object as null. This is not null If I try with non-multipart request.

Can you post the code that sets the session variables?
Also describe the flow of your application so we know when each component is executed.

Please start a new topic rather than piggy-backing on this old one. And clearly explain your issue.
