I'm in the httpsession != evil school and I'd say this isn't an occasion where you'd use it as you don't need anything to persist beyond the request (accept this default action thing whatever thats about).
The single action class as a type of command dispatcher sounds ingenious. But it has to be using a form property or request parameter otherwise the id in the link wouldn't do what you want. I can see how this has helped make life less complex :o) I assume it extracts a map iterates through is and then selects the relevant 'command' based on the map's contents.
You cant submit a form with a link without using javascript. You can use an image as a button, but thats another subject. I have no more suggestions than those I've already made, else I'll start getting urges to go out and score come crack in an attempt to save my teeth from all the brick-chewing.

Hi Avinash:
I have not followed your description very carefully - my eyes started
glazing over about mid-way..;) - but here's a thought (and I'm only
going by what i remember of your original question, so forgive me if I
misspeak..): If you do not have access to the request object, do you at
least have access to the session? In which case how about putting the
user in a session variable (maybe right after logon) and then you should
be able to get his/her userId etc etc wherever you want it from..? I
know there has been **extensive** discussion in this list re. the pros
and cons of using session variables and if you are of the
all-session-vars-are-bad school of thought, this won't do you any good.
But personally, this seems to be a situation where a session variable
would come in handy..
If however this idea wn't work in your situation, you may want to discuss with your clients their absolute requirement about wanting a link vs. a button (I believe you indicated earlier that the latter case will pose no prblems for you..?)
Good luck! Geeta

Hi Geeta/Paul/Mark/Wendy
What Geeta has suggested is basically the same thing but Paul is using JSTL for that. But such is the restriction of my application that I can not use request object to get the values from form directly by calling request.getParameter(...);
I will explain this why.
The framework that we are working with right now gives some add on features over struts. Basically taken from StrutsEJB framework.
We are using Map Based DTOs to transfer data from view layer to model layer and other way round. We are also using the feature of Command Files. I will explain it what it is for people unaware of StrutsEJB framework.
In Struts we are supposed to mention the Action Class in the struts-config.xml. And from the Action class we generally call some java programs (say command files) to access the model layer basically to avoid keeping business logic in Action Classes.
But in my framework we just need to mention the Command file name in struts-config.xml instead of Action classes. There is only one action class that is DefaultAction class which handles all the requests and diverts the program control to the command file. I will give here one typical entry in my struts-config.xml for your reference.
<action path="/CreateUser" type="framework.common.web.DefaultAction" name="UserForm" scope="request" input = "/CreateUser.jsp" parameter="app.cmd.CreateUserCmd"> <forward name="Success" path = "/UserSucc.jsp" /> </action>
in the above action tag the attribute parameter is the name of the command file where i would like my control to go after the form gets submitted.
Now the problem is in the Command File "CreateUserCmd" where i would keep my business logic -- i dont have the "request" object. so i cant do a "request.getParameter(.....); " here.
the way i get values from forms is like this.
if I have this code in JSP <html:text property="dto(txtUsname)" styleClass="listItem" size="14" />
I will have to write the following code in my command file to get the value of "User Name" String UserName = (String)paramDTO.get("txtUsName");
As Mark/Wendy were asking me why i cant use JavaScript is because
whenever i use something like this in JavaScript I get javascript error at runtime document.UserForm.dto(txtUsName).value = val; document.UserForm.submit();
This is obvious because whenever javascript parses something like dto(txtUsName) it takes it as a function call.
I hope I could explain the problem properly.

Avinash:
How about trying something like this:
<%String myLink = "/EmplyeeDetailAction.do?employeeId=" + employeeId; %>
<html:link page="<%=myLink">Employee Detail Page</html:link>

I want to use a hyperlink instead -
for example On a typical employee list page clicking the employee id of an employee takes you to the employee detail page.
In this scenario employee id can not be displayed over a button - it
has to be a hyperlink..function
Use of javascript is restricted. So i cant call a javascriptto set the action atribute and then call the submit function.
