I am trying to upload a file to WebLogic server using servlets. This is the doPost method:
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, java.io.IOException
{
boolean isMultipart;
String filePath=null;
int maxFileSize = 2 * 1024 * 1024;
int maxMemSize = 1024 * 1024;
File file ;
// Check that we have a file upload request
isMultipart = ServletFileUpload.isMultipartContent(request);
response.setContentType("text/html");
java.io.PrintWriter out = response.getWriter( );
if( !isMultipart )
{
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>");
return;
}
DiskFileItemFactory factory = new DiskFileItemFactory();
// maximum size that will be stored in memory
factory.setSizeThreshold(2 * 1024 * 1024);
// 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>Servlet 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();
ServletContext context = getServletContext();
Connection conn = (Connection)context.getAttribute("DBCON");
PreparedStatement stmt=null;
try
{
stmt=conn.prepareStatement("INSERT INTO emp VALUES(?, ?, ?)");
out.println("Created the statement!");
}
catch (SQLException e)
{
out.println("Unable to create prepared statement because: "+e.getMessage());
}
WriteToDB ob=new WriteToDB();
out.println("CWriting to DB!");
ob.process("C:\\JDeveloper\\mywork\\App\\Project1\\data" + "\\" + fileName, stmt, out);
out.println("Wrote to DB!");
}
}
} catch (FileUploadException e) {
}
out.println("</body>");
out.println("</html>");
}
And this is, as I've read, the important part of web.xml:
<context-param>
<description>Location to store uploaded file</description>
<param-name>file-upload</param-name>
<param-value>
C:\JDeveloper\mywork\App\Project1\data
</param-value>
I am using JDeveloper.
I have a standard upload HTML page with form data. Everything is fine, except that the file is not to be found at the stored location, and it throws that exception. Please help, thank you.
