good job maronepal, I'll try to add something as I come acrross. hope this is only for J2EE as the title says. not sure though, how useful would ppl find this thread as sun(sun.java.com)'s forum is of great help for most of the questions regarding Java/J2EE, but will definitely try to contribute..

What is Web Services?
  I came across this term for a while, i could not clearify myself what are web services and what it is use for? During my project i came accross some place where we use web services. I would like to share some information about how to use it and why it is use for.
   Web services are a collection of business logic which are developed so that a third party can use it without giving access to entire database or entire business logic.

  For example suppose say a company name XYZ has three other financial client A,B,C... so the company name XYZ has a software whose business logics are used by all of these client...... These client might require certain kind of business requirment to view data from the database. In this case the company name XYZ can't give full access to all the data, since some of the data belongs to other client.In this scenario the company name XYZ will create a web service where they will write certain function (business logic) and will give that access to company name A so that, a particualar company name A can get his requirment.So for a while it is like creating plugin for a company name A to get his data only. SOAP plays a role to communicate between these two company that is XYZ AND A. it is nothing but a protocal use to connect between these two company.

Hope it will help someone to know what is web services. Please correct me if i am wrong.

The power of software

Today and in the future, many of the jobs with the greatest impact will be related to software, whether it is developing software working for a company like Microsoft or helping other organisations use information technology tools to be successful.

Lifelong learning is vital

Communication skills and the ability to work well with different types of people are very important too.

A lot of people assume that creating software is purely a solitary activity where you sit in an office with the door closed all day and write lots of code.

This isn't true at all.

Software innovation, like almost every other kind of innovation, requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs.

I also place a high value on having a passion for ongoing learning. When I was pretty young, I picked up the habit of reading lots of books.

It's great to read widely about a broad range of subjects. Of course today, it's far easier to go online and find information about any topic that interests you.

Having that kind of curiosity about the world helps anyone succeed, no matter what kind of work they decide to pursue.

Bill Gates is chairman, chief software architect and one of the founders of Microsoft, the world's largest software company. From July 2008 he will end his day-to-day involvement in the company and focus on the Bill and Melinda Gates Foundation and its global health and education work.

Hi all,

I've deployed the session bean in a WebLogic Server. My JNDI.properties file has correct entries. I'm getting the following exception when calling one of the methods in the bean:

caused by: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

Any help would be highly appreciated. I'm not sure about "NoInitialContextException" as I see the bean with JNDI name in an application server.

Regards,
Kancha

Hi,

well not exactly.. but my suspect is that ur JNDI lookup connection is not set properly or so....

Many thanks for responding MaroNepal. Connection parameters were set correctly in jndi.properties as it made connection to the server successfully. Actually, it got resolved yesterday. Stupid mistake, typo in bean's name  while I was calling the method from my client code, as a result of which I was getting "NoInitialContextException".

Yea happens most of the time.. Hints always do copy---- paste.. donot type it.. will help you reduce error.

Some Tips on JSF(java server faces)

1.To add context path to URL for outputLink
<h:outputLink value="#{facesContext.externalContext.requestContextPath}/myPage.faces">

2.To get page Url

FacesContext fc=FacesContext.getCurrentInstace();
HttpServletRequest request=(HttpServletRequest)fc.getExternalContext().getRequest();
context.getViewRoot().getViewId();

3.To Terminate the session

FacesContext fc=FacesContext.getCurrentInstance();
HttpSession session=(HttpSession)fc.getExternalContext().getSession(false);
session.invalidate();

4.To reload page after ValueChangeListener

FacesContext.getCurrentInstance().renderResponse()
