Hi Faisal,
A great article and very detailed explanation has given. I was almost done with creating the new bean, but some exceptions occured. As per one of your comment I tried to install JVM and Tomcat both once again, but still has the same exception.
Following is my configuration.
JBOSS - 4.0.3 SP1
TomCat - 4.1.31
Java - 1.4.2_10
Please let me know if there is some other issue. Here is the exception which I have received.
javax.servlet.ServletException
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:498)
at org.apache.jsp.firstEJB_jsp._jspService(firstEJB_jsp.java:82)
