hello all,
Currently i am working with GWT. I need to convert the
uploaded file into byte array using Servlet . i have done that coding, when
i run the code in loacal machine i am getting the request type
as HttpServletRequest. when i run the code using JBoss 4.2 i am getting the
request type as RequestFacade. if i pass this request to the below Method i
am getting the null value.
upload.parseRequest(request);
And Here's my Servlet File:
public class FileUploadServlet extends HttpServlet {
public class FileUploadServlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 5482834513987308511L;
private String encoding = "UTF-8";
HttpServletRequest httpServletRequest;
// public final static org.apache.log4j.Logger LOGGER =
org.apache.log4j.Logger.getLogger(ClosingCommentsDAOImpl.class);
public FileUploadServlet() {
super();
}
@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
String initParameterEncoding = config.getInitParameter("encoding");
if (initParameterEncoding != null) {
setEncoding(initParameterEncoding);
}
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
this.httpServletRequest = request;
uploadFile(httpServletRequest);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void setEncoding(String encoding) {
this.encoding = encoding;
}
@SuppressWarnings("rawtypes")
private void uploadFile(HttpServletRequest request) throws
ServletException, IOException, Exception{
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List items = upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
//handling a normal form-field
if(item.isFormField()) {
System.out.println("Got a form field");
String name = item.getFieldName();
String value = item.getString();
System.out.print("Name:"+name+",Value:"+value);
} else {//handling file loads
System.out.println("Not form field");
String fieldName = item.getFieldName();
String fileName = item.getName();
if (fileName != null) {
fileName = FilenameUtils.getName(fileName);
}
String contentType = item.getContentType();
boolean isInMemory = item.isInMemory();
long sizeInBytes = item.getSize();
System.out.print("Field Name:"+fieldName
+",File Name:"+fileName);
System.out.print("Content Type:"+contentType
+",Is In Memory:"+isInMemory+",Size:"+sizeInBytes);
byte[] data = item.get();
fileName = getServletContext()
.getRealPath(fileName);
System.out.print("File name:" +fileName);
//convert array of bytes into file
FileOutputStream fileOuputStream =
new FileOutputStream(fileName);
fileOuputStream.write(data);
fileOuputStream.close();
System.out.println("Done");
}
}
}
Any one help me to find the solution.
Regards,
Kesavan g.
