I am new to Castor and am using the Castor Code Generator ANT task to generate code from a XSD schema file.

I am using a binding XML file as well. One thing that I have a question about is the needed XML mapping file. I set the ‘[b]generateMapping[/b]’ attribute to ‘true’ but have not found a mapping XML document.

Is there something I am doing wrong?

I have attached the XSD files(some are imported), binding XML file and the ANT build.xml file in a .zip file to this post.

Thanks in advance,

I'm having a problem understanding how jsp beans work:

I'm doing a login form and i'm having problems passing the information given by the user to the servlet.
I'm trying to use a bean as follows :

[code]
<jsp:useBean id="db" class="Beans.IdBean" scope="session" />
<jsp:setProperty name="db" property="*" />
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<form action="/WebApplication5/Servlet_Login" method="post">
Username: <input type="text" name="userName" size="10">
Password: <input type="password" name="passWord" size="10">
<input type="submit" value="Validate!">
</form>
</body>
</html>
[/code]

I've made sure that the name of the fields in the input(userName & passWord) is exactly as the one in the set and get methods of the bean, so supposedly the fields userName and passWord should be filled with the user's input right?

Now in the servlet i'm trying to retrieve the information like this:

[code]
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException, RemoteException
{
HttpSession ses = request.getSession();
IdBean id = (IdBean) ses.getAttribute("db");
//String user = request.getParameter("userName");
//String pass = request.getParameter("passWord");
String user = id.getUserName();
String pass = id.getPassWord();
System.out.println(user);
System.out.println(pass);
}
[/code]

I keep getting null when i print the variables user and pass. (and i know i could just do request.getParameter("nameofvariable") but i need to use beans)
Can anyone help me? What am i doing wrong? Or, am i even doing anything right?=P


Thanks in advance.

(Bean code in case anyone wants to see it)

[code]
public class IdBean
{
String userName;
String passWord;
public String getPassWord()
{ return passWord; }

public void setPassWord(String passWord)
{ this.passWord = passWord; }

public String getUserName()
{ return userName; }

public void setUserName(String userName)
{ this.userName = userName; }

}[/code]

It's one part of Shine enterprise pattern.

JShooter is a framework for distributing application programs on the network. Certainly, you have used RMI, Corba and JMS. Each of aforementioned technologies has its own special problems and at the same time enjoys extraordinary advantages. However, you must be careful about the expenses caused by these technologies. In most cases RMI, Corba and JMS increase the productions’ costs unbelievably. However in other cases they confuse programmers. Years ago, Reflect Oriented Programming was the focus of attention within professional programmers, then Aspect Oriented Programming came into the programming world but instead of reducing the programmer’s task, it causes the professional programmers and even the amateur ones to be confused in many cases. One of the most important capabilities of JShooter is that it makes the “Reflect Oriented Programming” easier to use.

1.Credit Facility Papers
2.Housing Loans Papers
3.Covering Approvals papers.

Unfortunately, a lot of programmers have involved and have ruined everything with malicious coding, due to poor documentations. Of course we don't have a single technical document today for further developments or fixing bugs. Many programmers have written their own methods, hence the same operation is executed in several places with several methods. After I undertake this application I added two modules more for Imports & exports, but because of the interdependency of the above mentioned 3 sections and the home page of the application, it was very hard to plug these two modules without any conflict.

So now we are thinking to develop a new version of this product with EJB 3.0 + JSF, so that it would help future developments with a few new and essential requirements. In this case I want to suggest our team to minimize (or rather get rid of) the interdependency between and among each module; even though we need to provide a common login for these five applications.

Is there any better technique to develop these 5 section as 5 separate applications and implement a single login for all of these applications? Just like we use several applications on facebook even if we log in only for once. If you have time, please recommend me the best or a better technique to do this as better as I can do.

....it will stop complaining about this value and then complain about another value which Spring says it can not convert from Date to String...


When the application runs on it's own, there is no need for a property editor. Can there be something I can do to get these mismatch errors to stop? Is there something I am doing wrong?

I know why I am getting the exception as I stated in my earlier post. The session is being closed when I try to access children (topics) of each category (parent). This is why I was trying to use OpenEntityManagerInViewFilter in the first place (to keep the jpa/hibernate session open so I can fetch the lazy topics (children of categories)
My only hunch is that the sessions are not unique but distinct. I.e. the session that is being used to get Categories is not being kept open for some reason.

listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
<!-- classpath:applicationContext.xml -->
<!-- classpath:/data-access-context.xml -->
classpath:data-access-context.xml
</param-value>
</context-param>

which references my entityManagerFactory like so:

data-access-context.xml:

<bean id="entityManagerFactory" >
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="dataAccessPU" />
</bean>
<bean id="transactionManager" >
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" >
ref="entityManagerFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />

The only thing that jumps out at me is the class definition for OpenEntityManagerInViewFilter:

Servlet 2.3 Filter that binds a JPA EntityManager to the thread for the entire processing of the request. Intended for the "Open EntityManager in View" pattern, i.e. to allow for lazy loading in web views despite the original transactions already being completed.

Servlet 2.3???
I am using Servlet 2.5 and JSP 2.1.
Does OpenEntityManagerInViewFilter not work for servlet 2.5 specs??

I am totally stumped

Anyone can lend some help? Please do...I have been stuck for a very long time
Thanks so much!!

p.s.
the point of this exercise is to actually not take a performance hit.
There will be potentially thousands of users at one single time, I cannot afford to load EAGER. because then each user will have the same categories and the same topics in memory.

I need to figure out how to load lazy.

I have searched thoroughly on the net but cannot find a solution to this problem, even though it is quite a common issue.

I thought the OpenEntityManagerInViewFilter needed to be simply plugged in...

I really need some help on this one...please reach out...

thanks again

I'm starting to develop an application on netbeans+glassfish+mysql.

I've created a facelet template to have only one time all the design part:

[code]<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>TrustBN - #{title}</title>
</head>
<body>


<ui:define name ="body"/>


</body>
</html>
[/code]

After this I just create a JSF page:

[code]<?xml version="1.0" encoding="UTF-8"?>
<!-- <br /> Document : testfile <br /> Created on : 18 juin 2009, 14:20:02 <br /> Author : J4N <br /> -->
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" >
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html" version="2.0">

<jsp:directive.page contentType="text/html" pageEncoding="UTF-8"/>
<f:view>
<ui:composition template="/WEB-INF/template.xhtml">
<ui:param name="title" value="toto"/>
<ui:define name="body">
<h:outputText>#{testfile2.toto}</h:outputText>
</ui:define>
</ui:composition>
</f:view>
</jsp:root>
[/code]
But I get this error:

org.apache.jasper.JasperException: PWC6228: #{...} not allowed in a template text body.

on the #{testfile2.toto}

I've try to do:
-The same thing without the template
-The same thing without the #{...}

And the two things works.

Must we use a special method to access to bean when we use facelets? Is it impossible? What do you recommend me? ]]> http://forums.hotjoe.com/posts/preList/601/2317.page http://forums.hotjoe.com/posts/preList/601/2317.page GMT going to the default error page
