I need to pass text field along with a image to a jsp page, and then in the jsp i want to retrieve the text field value. I am able to get the file in jsp and perform the required functions on it but I'm not able to get the text field value.
The, request.getParameter(); , function is returning null, and in this case, i've searched all the questions on stackoverflow, and it's not a duplicate question, plz provide a sol. :)
Thank You.
This is the HTML file :
<form name="upload" action="upload.jsp" method="post" enctype="multipart/form-data">
<input type="text" name="pro_sp" placeholder="product selling price"></p>
<input type="file" name="img">
<input type="submit" name="upload"></form>
This is the JSP file :
<%@page import="javax.servlet.annotation.MultipartConfig"%>
<%@page import="java.sql.PreparedStatement"%>
<%@page import="java.sql.ResultSet"%>
<%@page import="java.sql.Statement"%>
<%@page import="java.sql.DriverManager"%>
<%@page import="java.sql.Connection"%>
<%@ page import="java.io.*,java.util.*, javax.servlet.*" %>
<%@ page import="javax.servlet.http.*" %>
<%@ page import="org.apache.commons.fileupload.*" %>
<%@ page import="org.apache.commons.fileupload.disk.*" %>
<%@ page import="org.apache.commons.fileupload.servlet.*" %>
<%@ page import="org.apache.commons.io.output.*" %>
<% String x=request.getParameter("pro_desc");
out.print(x);
File file ;
int maxFileSize = 5000 * 1024;
int maxMemSize = 5000 * 1024;
ServletContext context = pageContext.getServletContext();
String filePath = "F:/img/";
String fname="";
String contentType = request.getContentType();
if((contentType.indexOf("multipart/form-data") >= 0))
{
DiskFileItemFactory factory = new DiskFileItemFactory();
// maximum size that will be stored in memory
factory.setSizeThreshold(maxMemSize);
// Location to save data that is larger than maxMemSize.
factory.setRepository(new File("c:\\temp"));
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// maximum file size to be uploaded.
upload.setSizeMax( maxFileSize );
try
{
// Parse the request to get file items.
List fileItems = upload.parseRequest(request);
// Process the uploaded file items
Iterator i = fileItems.iterator();
out.println("<html>");
out.println("<head>");
out.println("<title>JSP File upload</title>");
out.println("</head>");
out.println("<body>");
while ( i.hasNext () )
{
FileItem fi = (FileItem)i.next();
if ( !fi.isFormField () )
{
// Get the uploaded file parameters
String fieldName = fi.getFieldName();
String fileName = fi.getName();
boolean isInMemory = fi.isInMemory();
long sizeInBytes = fi.getSize();
// Write the file
if( fileName.lastIndexOf("\\") >= 0 )
{
file = new File( filePath +
fileName.substring( fileName.lastIndexOf("\\"))) ;
}
else
{
file = new File( filePath +
fileName.substring(fileName.lastIndexOf("\\")+1)) ;
}
fi.write( file ) ;
fname=(filePath + fileName);
out.println("Uploaded Filename: " + fname + "<br> |" );
}
}
out.println("</body>");
out.println("</html>");
}
catch(Exception ex) {
System.out.println(ex);
}
}
else
{
out.println(" <html>");
out.println(" <head>");
out.println(" <title> Servlet upload </title>");
out.println(" </head>");
out.println(" <body>");
out.println(" <p>No file uploaded </p>");
out.println(" </body>");
out.println(" </html>");
}
This is the output : null Uploaded Filename: F:/img/Chrysanthemum.jpg
