There are many methods to upload the document to the server. One of the way is through the MultipartRequest class. For the use of this class, you want to have the cos.jar file. In this example, we're offering the cos.jar file along with the code.
It is a utility class to address the multipart/form-information request. There are many constructors defined withinside the MultipartRequest class.
We are generating two files only that is index.jsp and fileupload.jsp, in the below given example:
To upload the file to the server, there is two necessity:
<form action="upload.jsp" method="post" enctype="multipart/form-data"> Select File:<input type="file" name="fname"/><br/> <input type="image" src="MainUpload.png"/> </form>
We are uploading the incoming file to the location d:/new, you can define your location here.
<%@ page import="com.oreilly.servlet.MultipartRequest" %> <% MultipartRequest m = new MultipartRequest(request, "d:/new"); out.print("successfully uploaded"); %>
If the size of the file is more than 1MB, you must define the post size.
