I started web development using JSF, after studying JSP and Servlets for a while. When you create a JSF web application you always(may be often but I am not sure if it always or not) have to create beans.xml and you don't write anything in it. But, if that file doesn't exist the JSF web app will not work. What is the reason behind that? Why we need that file? Please, detailed explanation. Adding to the answer of Micheal; CDI is not only useful in combination with JSF because of the injection support, but also because of its support to be used with EL (expression language). This is a feature

I have a property called isActive in my pojo class. When I generated the accessors for this property using Eclipse IDE, it generates following getters and setters Getter : isActive() Setter : setActive() However, when I try to write this property using ibatis framework by mentioning property name as "isActive" , it cribs about not able to find any WRITEABLE propery named 'isActive'. The problem I think lies with not able to deduce the correct property name by inferring setter as setIsActive(). What is the best way to go about this without changing the property name or getter ? primitive

I would like to configure a HttpParams using spring setter injection but HttpParams has a two argument setter ( setParameter(String name, Object object) ). Is anyone aware of a way to configure this in spring? The closest I can think of is like you would do a List, Set, or Property configuration: http://www.mkyong.com/spring/spring-collections-list-set-map-and-properties-example/ Thanks! Strictly speaking: A setter with two parameters is not a setter. It violates the JavaBeans convention, on which Spring builds. There is no simple way to solve that. As an alternative, here's a Helper class you

Hi is there a way to copy one class loaded context (atrributes etc) from one classloader (for instance a 'made' class Point) to another classloader? Making clear, Example: I have an object Point on CL 1. Now running on another CL2, I want to creat this object in CL 3. Some obj: class Point { int x; int y; public Point() {} //getters and setters Scenery: ... class CL2 { // Running on CL 2 ... // Point obj from CL 1 Object point = gotFromCL1(); // Want to create the object on Cl2 Object pointCL2 = point.conversion(); But I can't use sun.reflection (not available) and serialization doesn't work

When I run my application, it stops when beans are initializing but doesn't show any logs entries. So I don't know what happened: Log4j.properties log4j.rootLogger=DEBUG, stdout, R log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout org.springframework=DEBUG org.springframework.beans.factory.support=DEBUG log4j.logger.org.springframework.beans.factory.support=DEBUG log4j.logger.org.springframework.beans=DEBUG log4j.category.org.springframework.beans.factory=DEBUG log4j.logger.org.springframework=DEBUG log4j.logger.org.hibernate.hql
