I am new in XSLT and I started to support an application which has the servlet below. Which are the patterns in this servlet related to XSLT? Beyond the basic methods get and post, I didn't understand the purpose of too many methods. Obviously I can debug but I can figure out every purpose because it is not clean code: at least when I compare with much more straight forward servlets that I have supported. It seems that who has developed this application has used some common practice of wrapping DOM and SAX methods.
I'm trying to pass a parmeter to a jsf page from a servlet(i.e. associated with paypal adaptive api), but I keep getting the following error, even though the productType on ProductDetailsVO is a String.

Calling JSF page contains:-
returnURL = new URL(new URL(request.getRequestURL().toString()),"pages/paypalpaymentapproved.xhtml?paypalID="+paypalID+";productType=Sport"); response.sendRedirect(returnURL.toString());
How should I access object, which I have created in servlet? Servlet handles the requests(controller) and forwards to requested jsp page.Some of the jsp pages need EJB objects. When i create an ejb object in servlet and then forward the request to jsp, how can i access the object in jsp ? This should be MVC - based application, like JSP-Servlet-EJB.
I am trying to generate table rows from LinkedHashmap sent from servlet. But whenever i execute i get empty or null map. I tried running the servlet alone to check whether the data is existing in linkedhashmap and it does. But only when i pass it to the jsp page i guess i am receiving an empty map.
Below is the code
Jsp Code:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
I have a jsp with an img tag whose src is set to request a servlet to display a chart. This is called from another jsp form where user can select various filters. The first time the request is made all works great. but if the user changes the filter settings and and makes the servlet request a second time the chart stays the same. I have verified the new filter values are being set but the servlet is only being called on the initial request.at the head or called servlet I have(I also call a jquery empty on the div that holds the chart between requests. at the moment it just displays the former chart). It is like it is using cache:
I've written a simple html/servlet program that has a user enter their name and password on a form and then either register or login using a submit button. I have the program working, except when a user doesn't fill in either of the text fields I can't figure out how to get it to print to the page. Right now I just have it printing to my Eclipse console which is not what I want. What am I missing?

When I am entering the student name , his/her details should be retrieved from database by servlets and the data to be print in jsp pages this what I want But I am unable to display the data from database in jsp pages .
On click of the ok button from a JSF page, a servlet is called on a new window. Servlet creates a CSV file , which will be streamed back for a download. Now if there is a error in the servlet, how can this be shown in the parent JSF?
I am trying to print the response of servlet as pdf. Below is my codeI am able to generate the response but not quite sure how should I write it to a pdf.
In my jsp, I have a table with some file paths with this I have to get the file and send it to server. I am able to read the file name, size and file as binary using files of javascript. But after that I need to send those files by storing in a byte array to servlet which I am not able to that. Is there any way I can send that. My requirement is I need to upload those files to server side.
Modify the program in Assign4 to synchronize access to the instance variable, balance. Save the program as SyncBank.java. Because balance is a double and not an object, it cannot be used as the monitor. Use synchronized methods or synchronized blocks of code as appropriate. Simultaneously test two threads as was done in Assign4. Because the threads can complete too quickly to determine if they are interfering with each other, delay the adding of a deposit by inserting the following code within the synchronized block or method:
<% request.setAttribute("from", new String("test"));%>
And the I try to send the "from" value to my controller like this:
<p><a href="UserController?action=listNoDeletedFilterdUsers&from=<c:out value="${request.getAttribute('from')}"/>"> Eliminar usuarios por rango de fechas</a></p>
When I press the link and chech the HTML generated it looks like this:

Using Eclipse I have imported a WAR with source. I have exported that project as a new war and it ran fine. I then added my own package and exported the war again. The jar file does not show up in /WEB-INF/lib folder. When I deploy the war on a tomcat server it barfs the following error:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.sharpline.fields.form.fields.TextAreaFormType] for bean with name 'com.sharpline.fields.form.fields.TextAreaFormType#53c37' defined in ServletContext resource [WEB-INF/activiti-standalone-context.xml]; nested exception is java.lang.ClassNotFoundException:
[Code] .....
It looks to me like my class (jar) is missing in the final war. How do I resolve this?
