certification for banking domain

Hi,
I don't know whether I am putting query in the right section.

I am a java programmer and currently working in a project pertaining to banking domain.

Is there any certification which would benefit my career growth?

Thanks in advance.

Then why are the contents not equal?

difference between contents of view source of a web page and url stream

Hi,

I am trying to fetch the contents of a web page programmatically by using java.net.URL class. After opening the stream for the url, I am able to read the contents. I am of the opinion that this content should exactly be same as the contents of the page source.

Am I wrong? If yes, then what are the differences between those two contents?

HTTP Status 405 - HTTP method POST is not supported by this URL.

Bear Bibeault wrote:That is not necessary.

Simply implementing doPost() and not calling the super method should be sufficient.

thanks Bear!

That did the trick.

Would you please tell me why the problem occurs when I make the call to super?

Servlets

HTTP Status 405 - HTTP method POST is not supported by this URL.

<servlet-mapping> element in web.xml can contain only <servlet-name> and url-pattern.

The schema doesn't allow me to put http-method tag inside it.

Hi Swastik,

I have already overridden the doGet and doPost method in the servlet.

HTTP Status 405 - HTTP method POST is not supported by this URL.

Hi,

I am trying to build a web application from where file can be uploaded to the server.

the html page looks like as follows:-

The web.xml file looks like:-

I am usging tomcat 6.

I have written a FileUploaderServlet that writes the file to the server's local directory.
The FileUploaderServlet looks as follows:-

package com.test;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import java.util.List;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.FileCleanerCleanup;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.io.FileCleaningTracker;
import org.apache.commons.io.FilenameUtils;
public class FileUploaderServlet extends HttpServlet{
/**
*
*/
private static final long serialVersionUID = 1L;
private final String SUPER_DIRECTORY = "E:\\java_workspace\\EclipseProject\\JspProject\\mainFolder\\";
public FileUploaderServlet()
{
//super();
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
@Override
protected void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException {
// TODO Auto-generated method stub
super.doGet(request, response);
doPost(request, response);
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
super.doPost(request, response);
DiskFileItemFactory factory = newDiskFileItemFactory(getServletContext(),new File("c:\\Temp"));
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setSizeMax(500000);
try {
List<FileItem> items = upload.parseRequest(request);
Iterator<FileItem> iter = items.iterator();
while (iter.hasNext())
{
FileItem item = iter.next();
if (item.isFormField()) {
//processFormField(item);
} else {
processUploadedFile(item);
}
}
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html><head><title>File upload</title></head><body>Uploaded file.</body></html>");
out.close();
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private void processUploadedFile(FileItem fileItem)
{
String userName = "abc"; //get the user name from session
File dir = new File(SUPER_DIRECTORY+"\\"+userName);
dir.mkdir();
String fileName = fileItem.getName();
if(fileName!=null)
{
fileName = FilenameUtils.getName(fileName);
}
File uploadedFile = new File(dir.getAbsolutePath()+"\\"+fileName);
try
{
fileItem.write(uploadedFile);
}
catch(Exception e)
{
e.printStackTrace();
}
}
public static DiskFileItemFactory newDiskFileItemFactory(ServletContext context,File repository)
{
FileCleaningTracker fileCleaningTracker = FileCleanerCleanup.getFileCleaningTracker(context);
DiskFileItemFactory factory = new DiskFileItemFactory(DiskFileItemFactory.DEFAULT_SIZE_THRESHOLD,repository);
factory.setFileCleaningTracker(fileCleaningTracker);
return factory;
}
}

Everything works fine and I am even able to get the file on server. But once the doPost() method of the servlet completes, it gives me

HTTP Status 405 - HTTP method POST is not supported by this URL.

Any idea where things are going wrong?

Resource not found

Hi,

I have a html page from where I am trying to call a servlet.

the html page looks like as follows:-

The web.xml file looks like:-

I am usging tomcat 6.
Now when I submit the html form, it ideally should invoke the servlet but I am getting "The requested resource (/servlet/FileUploaderServlet) is not available." instead.
The snapshot of the directory structure of my web application can be found in the attachment.

Can anyone give me any pointers where I am committing the mistake?

changing the session timeout value

Thanks Ashokan!!!

I want to configure the session timeout interval through weblogic 8.1 server console.
Explored all the options but failed to find any option that would allow me to set the
session timeout period.

If you or anyone have any idea about it, please share that with me.

Thanks in advance.

changing the session timeout value

Hi,

I have created a web application and deployed it on weblogic 8.1 server.
I want to change the session timeout period. I know that it can be changed by
changing the value in web.xml or weblogic.xml

Can I change the session timeout value through weblogic console?

Yeah... a bad file is generated.
But my question is will I have to skim through the generated .bad file in order to find if any error has occurred during data loading??
