You would pass the bean instance and session object as parameters in a JSP
function (called a method).
For Example, you would say:
jsp:useBean id="chk" scope="page" class="Alpine.chkBean" /
%!
int chkID(String strBar, Alpine.chkBean chk,
javax.servlet.http.HttpSession session)
{
You cannot call methods of JSP or Serlvets from outside.
A calling servlet or jsp is one that forwards itself to
another jsp or serlvet and does not return.
A Servlet or JSP loads once and thereafter is loaded, until changed again.
Once loaded, a calling jsp or serlvet will not cause it to
Do it via Interfaces:
Make an interface that describes the methods of CorbaConnection
Call it CorbaInterface_A.
have CorbaConnection implement CorbaInterface_A
Next say:
CorbaInterface_A corbacon = con.get();
This is how true Object Oriented Programming Works.

Use StringBuffer.append. Don't use += of String for large Strings because
everytime you use += a new String is constructed and the previous String is
garbage Collected. StringBuffer.append, on the other hand, truly appends
the String to the StringBuffer and no garbage collecting is done. Hence
Use the forward tag:
jsp:forward page="mymainjsp.jsp"/

How do I send parameters to a servlet.
I have considered reading files inside the method
public void init(ServletConfig config) throws ServletException{
super(config);
//read file...
}
but I wonder if there is a better solution.
Thanks a lot, Eric
Why would the same SQL Query to the Connection bean provided by JRun
sometimes returns an empty result set and other times work?
We cannot figure it out. It has a connection each time- it returns true,
but when getting the result set it sometimes returns an empty set and other
times works.
Do
you,
