In general file upload means to receive data from a remote system to a local system. So coming to programming language a JSP can upload file on server by using html form tag. An uploaded file could be text file, image file or any document file.

In JSP we can upload files using multipart/form –data. This can be used to when we need to upload files on server. If we upload large files of mime-types or content types then JSP doesn’t process the request. So we should set maximum file size of in the property files. To upload single file we use single tag with attribute type =”file”. If we want upload multiple files then we should use more than one tag with different values with name attribute.

Creating a File Upload Form

To upload a file on server we can make use of <form> tag. It can be written as follows:

• action attribute: It is url of the script the content should be sent to, means it is used to forward request to another resource.
• method attribute: it specifies HTTP method to be used when sending form data. It can be post or get. But here we are setting it to post method.
• enctype attribute: It is used to upload files on server using method called “multipart/form-data”

Upload File Example

1. First we will create one Jsp file called index.jsp. It contains <form> which is used to upload file and forward request to another resource and HTTP method type post.
2. FileUploader Servlet and handles the request for file upload and uses Apache FileUpload library to parse multipart form data.
3. Configure servlet and JSP details in web.xml
4. Create second Jsp file called as result.jsp . It will display the message whether the file is uploaded successfully or not using requestScope[“message”] method.
5. To execute this program you would need to include in your WEB-INF/lib folder.
   • commons-fileupload-1.3.jar
   • commons-io-2.4.jar
   • javax.servlet-api-3.0.1.jar

Listing 1: FileUploadHandler

Listing 2: web.xml

Listing 3: hello.jsp

Listing 4: result.jsp

Execute the jsp file hello.jsp in Eclipse by selecting Run As > Run On Server.
