Actualy i just want to send an attachment using javamail api....previously my code was working fine suddenly its not working....i did nt use enctype="multipart/form-data" bt it was working fine. whenever i am using this code means enctype="multipart/form-data" i am getting null value using request.getParameter from servlet as servlet not support it...i just want to know how can i get the value.... And i also want to know what value actualy we should get..means should we gt the actual path of the file means filename="c:/a.doc" or only a.doc.
<form METHOD=post ACTION="action.cgi" ENCTYPE="multipart/form-data"> <input TYPE="file" NAME="filename"> </form> I have used daman sidhu's multipart class to solve this problem. i got null values in myParam;and got .\a.txt value from File f=multi.getFile(name);I think i should gt the full path dat is d:/a.txt.
One more thing after using this code whenever i m trying to get other field using normal process request.getparameter (name)...i m getting null value...
please help me in this regard............ thanks in advance

Hi Unfortunately, the servlet API provides no high-level tools to read uploaded files;you have to call request.getInputStream and parse the request yourself. Fortunately,numerous third-party libraries are available for this task.One of the most popular is from the Jakarta Commons library;for details ,see http://jakarta.apache.org/commons/fileupload/.
