Hey!
Can I make a suggestion about control structure.
I only briefly looked at this thread, so I may be way off base.
You authenticate, good. Client then asks for a service to be performed, good.
At that time you should know what JavaBean-Model he needs, right. So
while in the servlet, get an instance of the bean, okay. It's empty at this
point.
Fill it up, create a session object, and put the bean in the session-object,
forward()
to client a View-JSP. Get the session object while in the View-JSP and therefore
get the JavaBean. Now use the bean in the View-JSP.
Hopes this helps.
Also, some things about JRun, I too am forced to use it, against my preferences.
Given:
WEB-INF/com/yourcompany/yourapp/MyClass
Like posted already by someone else:
<jsp:useBean id="myservice" class="com.yourcompany.yourapp.MyClass"
scope="session"/>
For JRun, always restart the server if you change this class.
Don't use the DEFAULTAPP, for how are you going to keep your apps organized.
Create an application, YOURAPP.
Method 2.
Once you have YOURAPP, now you can use the web.xml to your real advantage.
Let JRun create a web.xml for you that you can edit. Put web.xml-type of things
in
it. Just remember that if you use JRun's web interface to the web.xml it will
overwrite
your edited version.
Why? Because now you can do such things as getServlet().getInitParameter(),
powerful.
Also, you can now do this:
<jsp:useBean id="myservice" class="MyClass" scope="session"/>
Where, 'myservice' is the named you assigned in the web.xml to
com.yourcompany.yourapp.MyClass.
Sans adieu,
