I am getting null value when I use request.getParameter("fieldname");.
I checked for the value in Javascript on button and it reaching there.
below is my code
public String pageHTML()
strBuffer.append("<form method=\"POST\" enctype=\"multipart/form-data\" action=\"");
strBuffer.append("\" name =\"solution\" id = \"solution\">");

strBuffer.append("<span><input id=\"txtUserId\" name=\"UserId\" size=\"5\" maxlength=\"4\" tabindex=\"6\" ></input></span>\n");
strBuffer.append("<span><input id=\"txtUserId\" type=\"text\" name=\"UserId\" size=\"5\" maxlength=\"4\" tabindex=\"6\" ></input></span>\n");
strBuffer.append("<input type=\"button\" name=\"btnSendFeedbacks\" value=\"Send Feedback\" inclick=\"fn_SendFeedback();\" >");
return strBuffer.toString();

This page is calling result.jsp


String strSS = request.getParameter("UserId");
out.println("the request parameter is : " + strSS);

</htm >>>

Any help is appreciated.

With multipart forms, getParameter doesn't work.
You need to read the documentation for the upload libraries you're using to see how to read form parameters.

Why on Earth are you building up HTML from within Java code?
The whole point of templating languages like JSP/ASP/PHP is to free developers from having to do this.
