Is Hidden Field Passed As a String?

[Caroline Jen]

I am passing a hidden field from my JSP to my form
bean:



Is the property "parent" considered a String in the
form bean?  Do I have to use 

BeanUtils.copyProperties( postDTO, postForm );

to convert that property to a primitive type int?

RE: How To Output the Value Of a Hidden Field?

[Robert Taylor]

There are a couple (3) ways to do it.

1. Have both JSP#1 and 2 use the same form then have the action that
processes JSP#1 simply
forward to JSP#2 and Struts will auto-populate the field.

2. Have the action that processes JSP#1 forward or redirect to
   JSP#2 whose form has the same property name. Place the create property
   value in the query string and Struts will auto-populate the form
   in JSP#2.

3. Have the action that processes JSP#1 access and populate the form used
   in JSP#2 with the property then forward to JSP#2.

[Koni Roth]

You cannot have two properties with the same name in a form.
Try:

" size="82" maxlength="25" tabindex="1"/>

Sounds like a classic no /> at end of tag. It is bodyless but now thinks 
the remaining part of the code is within a body...

I did another test.  I took out those data access
activities in the FindEditorData.java and ran the
application.  The conclusion is that those few lines
of data access activities have nothing to do with the
value of the 'username' becoming null in the
FindEditorData.java.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

I followed your advice.  In the Bean.java, I did the
following:

private String username = "natalie";
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}

and I compiled all the relevant classes, re-run the
application, the FindEditorData.java writes out the
following in the browser:

The process did not complete. Details should follow. 
name=natalie; kn=journal_category; kv=null 

Now, the question is why the Bean.java does not pick
up the value of the hidden field 'username' from my
JSP while successfully picks up the value of the other
hidden field 'keyName'.

There is some data processing activities going on in
the FindEditorData.java:

   String username = getUsername();
   EditorService service = new EditorService();
   String value = service.findEditorData( username );

The above data accessing codes had been tested outside
the environment of the application (the codes did what
I expected them to do without problem) before they
were integrated into the application.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

Caroline,
As a sanity check, in your bean, initialize the
username variable to something ie. "XX". and
re-run your app. This will show if your setUsername is
ever called.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

I do not fully understand what you say about null or
"null".  Anyway, I did try to write out values in the
FindEditorData.java.  What is written out in the
browser is:

name=null; kn=journal_category; kv=null

And the way I try to write out those crucial fields is
shown below:

// package and import statements omitted
public final class FindEditorData extends Bean
{
   public Object execute() throws Exception
   {

   // Obtain username 
   String username = getUsername();
  
   EditorService service = new EditorService();
   String value = service.findEditorData( username );

String property = getKeyName();

if (( null==property ) || ( null==value )) 
{
StringBuffer sb = new StringBuffer();
sb.append( "name=" );
sb.append( username );
sb.append( "; kn=" );
sb.append( property );
sb.append( "; kv=" );
sb.append( value );
throw new ParameterException(
sb.toString() );
}

ResultList list = new ResultListBase
(

Access.findByProperty( this,property,value
)

);
list.setLegend( property,value );

return new ProcessResultBase( list );

   } // end execute

} // End FindEditorData

[Richard Yee]

Caroline,
In your FindEditorData.java class, is the value for
your username variable null or "null"?  If it is null,
then you are reading the wrong request parameter since
request.getParameter() will return null if the
parameter doesn't exist. If the String value is
"null", then you have a problem with getRemoteUser()
Why don't you dump request parameters that you are
getting in your FindEditorData?

Hidden input tags work fine.

Richard

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Caroline Jen]

Hi, I think that we are in different time zones.

As you have mentioned, I, too, suspected that the
statement in my JSP:

request.getRemoteUser(); 

returns nothing.  Therefore, I did a test in my JSP. 
In addition to request.getRemoteUser(); I created
another String manually:


<% 
   String username = request.getRemoteUser(); 
   String userrole = "author"; 
%>   
<% out.println("The user name is: " + username +".");
%>
<% out.println("The role is: " + userrole +"."); %>


And the browser shows:

The user name is: Gloria Jen.  The role is: author. 

Gloria Jen is the name that I provided while logging
on and authenticated by the container.  Therefore, the
request.getRemoteUser(); does not return a null.  And
I hope that it means I am not passing a null value
when I use the hidden field technique.

Then, I pass two hidden fields (with value in them)
from my JSP to a Java class (FindEditorData.java),
which is of scaffold.ProcessAction type.  One of the
field is passed with its value correctly retrieved. 
The other field is passed with its value found to be
null.

What could go wrong?  I have been thinking about it
for days and so do those who try to help me.  



<% 
   String username = request.getRemoteUser(); 
   String userrole = "author"; 
%>   
<%out.println("The user name is: " + username +".");%>
<%out.println("The role is: " + userrole +".");%>

Rats, the thread broke, hence my other reply. Like everyone says, you 
need to check the return value of getRemoteUser() - try looking at the 
value of the hidden field in the HTML via IE's 'Show page source'.

It is impossible for request.getRemoteUser(); in my
JSP returning a null.  (see code below) Before it
reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

[Adam Hardy]

Hi Caroline,
have you checked the source of the HTML page in the browser to see what 
the value of username is, client-side? I expect the value is being sent 
to the browser as null.

If that is the case, it is because request.getRemoteUser() is returning 
null and that would be because you don't have or are losing your login 
session.

Caroline,
Why are you passing the result of request.getRemoteUser() in a hidden 
variable anyway since it is available as part of the HttpRequest and thus 
will be available in the action class?

Caroline,
Did you check the result of getRemoteUser(). Does it return null or "null"? 
If so, it's not a problem with your hidden form variables,.

RE: Please Help! Unable to Pass A Hidden Field To scaffold.Proces sAction

[Yee, Richard K,,DMDCWEST]

Caroline,
Imposible? Look at the HTML that is generated by the JSP page. I think you
will see that it returns "null".
Take a look at the JavaDoc for HttpServletRequest.getRemoteUser();

getRemoteUser
public java.lang.String getRemoteUser()
Returns the login of the user making this request, if the user has been
authenticated, or null if the user has not been authenticated. Whether the
user name is sent with each subsequent request depends on the browser and
type of authentication. Same as the value of the CGI variable REMOTE_USER.

Returns: a String specifying the login of the user making this request, or
null 

As the JavaDoc says: "Whether the user name is sent with each subsequent
request depends on the browser and type of authentication."  Are you using
basic authentication or are you authenticating the user yourself?
If you are doing it yourself (ie. through a db lookup) then the server
doesn't know about the user being authenticated and will return null.

Regards,

Richard

I pass two hidden fields: username and keyName at the

value in it.  The username is passed but its value
turns out to be a null.

It is impossible for request.getRemoteUser(); in my
JSP returning a null.  (see code below) Before it
reaches request.getRemoteUser(); the user has already
been successfully logged in with a valid name.

Caroline,
Are you having problems with the username or the keyName hidden variable? If
it is the username, then I'd suspect that request.getRemoteUser() in your
JSP is returning null.

Richard

I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the scaffold.ProcessAction.  If
it had been the lowercase/uppercase problem, I would have gotten a message
saying that the variable could not be recognized.  

I pass two hidden fields at the same time.  One of
them is successfully passed with correct value.  The
other is passed but its value shows a 'null' in the scaffold.ProcessAction.
What could go wrong?  Let me show my code again:

Two hidden fields: username and keyName are passed 
from a JSP via a SUBMIT button:



<% String username = request.getRemoteUser();%>


View Articles



and an action mapping:


   


The value of the 'username' is found to be a 'null' in
the FindEditorData.java while the value of keyName is successfully
retrieved.  In the browser, I got:

name=null; kn=journal_category; kv=null 

The code of my FindEditorData is shown below:

public final class FindEditorData extends Bean
{
   public Object execute() throws Exception
   {

   // Obtain username 
   String username = getUsername();
  
   EditorService service = new EditorService();
   String value = service.findEditorData( username );

   String property = getKeyName();

if (( null==property ) || ( null==value )) 
{
StringBuffer sb = new StringBuffer();
sb.append( "name=" );
sb.append( username );
sb.append( "; kn=" );
sb.append( property );
sb.append( "; kv=" );
sb.append( value );
throw new ParameterException(
sb.toString() );
}

ResultList list = new ResultListBase
(

Access.findByProperty( this,property,value
)

);
list.setLegend( property,value );

return new ProcessResultBase( list );

   } // end execute

} // End FindEditorData

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

[Caroline Jen]

I did not mess up lowercase and uppercase of the
hidden field I want to pass from my JSP to the
scaffold.ProcessAction.  If it had been the
lowercase/uppercase problem, I would have gotten a
message saying that the variable could not be
recognized.  

I pass two hidden fields at the same time.  One of
them is successfully passed with correct value.  The
other is passed but its value shows a 'null' in the
scaffold.ProcessAction.  What could go wrong?  Let me
show my code again:

Two hidden fields: username and keyName are passed 
from a JSP via a SUBMIT button:



<% String username = request.getRemoteUser();%>


View Articles



and an action mapping:


   


The value of the 'username' is found to be a 'null' in
the FindEditorData.java while the value of keyName is
successfully retrieved.  In the browser, I got:

name=null; kn=journal_category; kv=null 

The code of my FindEditorData is shown below:

public final class FindEditorData extends Bean
{
   public Object execute() throws Exception
   {

   // Obtain username 
   String username = getUsername();
  
   EditorService service = new EditorService();
   String value = service.findEditorData( username );

   String property = getKeyName();

if (( null==property ) || ( null==value )) 
{
StringBuffer sb = new StringBuffer();
sb.append( "name=" );
sb.append( username );
sb.append( "; kn=" );
sb.append( property );
sb.append( "; kv=" );
sb.append( value );
throw new ParameterException(
sb.toString() );
}

ResultList list = new ResultListBase
(

Access.findByProperty( this,property,value
)

);
list.setLegend( property,value );

return new ProcessResultBase( list );

   } // end execute

} // End FindEditorData

Re: Please Help! Unable to Pass A Hidden Field To scaffold.ProcessAction

[Caroline Jen]

My code was shown in my original message.  I used two 
 tags to pass two hidden fields, one
is successfully passed while the other shows null.  By
the way, I do not use 'request' to retrieve the value
of the hidden field because my Java class is a
scaffold.ProcessAction type.  I simply use getXxx.

Let me show my code again:


<% String username = request.getRemoteUser();%>

Hidden Field

[Caroline Jen]

works well because "author" is expected literally as
the value of a property called "dispatch".

I also want to pass 
String username = request.getRemoteUser(); 
as the value of a property called "keyValue".

But,

or


gives me problems.  What is the proper way of doing it?

Re: Struts Validator and Hidden Field

[Joe @ Team345]

Octavia,

I bit of a guess on my part, but it sounds like you want to use the 
"requiredif" validator.  This allows a particular field to be required 
(or not) based on other fields.  The fact that this might be a hidden 
field should be, as pointed out by others, transparent to the validator. 
However, also pointed out is the most troubling question: if it is on a 
hidden field and your validation fails, what can your users possibly 
ever do to correct the situation?

You'll have to post some of your code before anyone will have any idea why
it's not working.

The Validator also logs copious amounts of info, you should be able to tell
if your rule is getting picked up from the XML file by looking in the logs.

Re: Get request property value into Hidden field?

[Alen Ribic]

seems like request processor will populate my request object with "id" form
property.
this sounds perfect, I'll try this out.
all I need to do is add the action mapping for the one that just forwards to
deleteItem.jsp page.
this should result in population of my "id" property.
my delete action method already does the right thing when deleteItem.jsp is
posted.

Thanks again for your help.

yes, it should.

snippet from request processor:

// Process any ActionForm bean related to this request
ActionForm form = processActionForm(request, response, mapping);
processPopulate(request, response, form, mapping);
if (!processValidate(request, response, form, mapping)) {
return;
}

Re: Get request property value into Hidden field?

[Alen Ribic]

thanks Krishna for your reply again
you right.
I rethought my design, use case, and have determined that the best way to go
about it is to send it to the action method
first then forward it to my delete view page.
This will give me more control over the item deletion request. (e.g. check
"id" correctness, if not ok then announce error.)
I'll have a same delete action method that will accommodate both call from
listItems.jsp as request for deletion and deleteItem.jsp view that will
perform the post to action for actual deletion process.

So I'm thinking something like this in words...

public ActionForward deleteItem(...) {
[if Form Bean not set as request attribute,
set it with new Item bean and set "id" parameter in bean.
Then forward to "deleteItem.jsp"]

   [Otherwise if Form Bean attribute is set (in this case if deleteForm has
been posted)
then run the delete business logic process command and forward to
Success page!]
}

does this sound right to you? :)

RE: Get request property value into Hidden field?

[Krishnakumar N]

Its considered "best practice" to always route the requests thru an action
mapping which can be just an empty forward as follows:



Coz then you are able to add processing logic later (if the need arises) by
changing the action mapping without touching the pages which have the link.

In your case, this mechanism would help populate the action form
(deleteform) with the id value.

Krishna

Re: Get request property value into Hidden field?

[Alen Ribic]

why do I need to go the action before I have given the user a e.g. delete
"yes/no" option?
my deleteItem.jsp?id=20 gives them the ui yes/no options.
is this because I would need to set the form bean as a attribute there or?
something like this in action method...
request.setAttribute("deleteForm", new
Item().setId(request.getParameter("id")));
then forward to the deleteItem.jsp page?
is this necessary?
because after that I need to post again to delete the actual object from
persistence storage.

I know what the "id" is and that's the only info I need, and I just wish to
grab into hidden field and post it to the delete action.

I think this might be something in my form config. that the parameter is not
being pulled through.
I'll work it out. Probably something silly anyway :)

Re: Get request property value into Hidden field?

[Alen Ribic]

oops.
thanks.
I mean getParameter() of course.

It's just simply an Id that gets passed as a parameter that I will need to
store in hidden field and then post of to another action method.

So, it's like this.

> listItems.jsp
---
...
href="./deleteItem.jsp?id=20"
...
---

> deleteItem.jsp?id=20
-


...


-

When Struts renders the html, in browser / view source,  tag
doesn't store the "id" parameter value.

should of course be


Does this make sense? :)
If not, I'll need to look into the issue a bit more myself with regards to
the design.

Thanks

RE: Get request property value into Hidden field?

[Krishnakumar N]

request does not have a getProperty as far as I can see, so do you mean
getParameter()?

In that case, the easy way to handle this is to get the value into the
action form (which happens automatically if the action form has a matching
property) and then populate the html:hidden from the action form (which is
also automatic, if you are on the same form).

Krishna

Just looked at this reply - I wonder why I said put these methods in an object in the

They can just be static methods of any class.

Re: How to store a String[] in a hidden field?

[Keith Bacon]

How about putting a helper class in your session which has methods:-

String stringArrayToTokenizedString(String[] array)
   //store array elements delimted by some char that's not in the data.

String[] tokenizedStringToStringArray.
   //Use StringTokeniser to build the array again.

Then you need only store 1 big long string.
Personally that seems fairly horrible too but at least there's less JSP code.

How to store a String[] in a hidden field?

[Christian Bouessay]

Hi,
I have a form with a multiple select box.

class myForm1 extends ActionForm {
 String[] getFields() { ...}
 void setFields(String[] fields )
 ...
}

 


When I submit the form and validate() return null, it forwards to an 
other view of the same form where I would like to store this property in 
a hidden field.

And HTML output is:



How can I tell struts to store it in a "String" format?


Thanks for help.

AW: Hidden Field in a form. Do I use struts taglib or vanilla html?

["Moritz Björn-Hendrik, HH"]

Ted,

a great idea, but you need to know the name of the actionForm in the
jsp-Page. If you change the name in the struts-config.xml, you have to
change it here, too. Doesn't this hurt struts design principles? Isn't it
better (at least until struts 1.1 is released) to have two methods on the
actionForm-class, one for the values and one for the values, which
internally (i.e. in java-Code) map to a method named getNames?

Re: Hidden Field in a form. Do I use struts taglib or vanilla html?

[Greg Callaghan]

Ted,

Again this is great information. I think it confirms something I have been 
struggling with -:

I am trying to handle the CANCEL case of an "edit a record" screen which was 
arrived at from the previous "list of records" screen.  They use the same 
formbean which has an "action" field.  When entering the first "list of 
records" screen it is set to "action=display", and when entering the "edit a 
record" screen it is set to edit/add/delete as approrpriate.  The reason for 
this is my formbean validation differs in the two cases (another story).

The problem I have is if the use hits CANCEL on the "edit a record" screen I 
wanted to send them back to the "display list of records" screen via the 
associated action (cf directly to the JSP), ie so that the action sets up 
appropriate objects required (don't want to recode this).

The catch seems to be I need to set the "action" request parameter back to 
DISPLAY from say EDIT in the "edit a record" action prior to forwarding to 
the "display list of records" action.

It seems this may not be possible??

- setting action element in the form from within the action prior to the 
forward doesn't work as the pseudo code below indicates that "If a form bean 
is in play, the ActionServlet resets and populates
it from the HTTP request"

- I still haven't found a way to override a request parameters value from an 
action yet??? (it seems possible using a JSP tag, ie the forward tag, so 
maybe I just haven't worked it out yet)

Other this this maybe I need to re-think the design?  :-)

Ideas anyone?

Cheers
Greg

Subject: Re: Hidden Field in a form.  Do I use struts taglib or vanilla 
html?
Date: Thu, 29 Nov 2001 14:16:11 -0500

The general order of things is

1) Client requests an Action URI (the path from the ActionMapping)
2) The container passes the request to the ActionServlet
3) The ActionServlet looks up the mapping for the path
4) If the mapping specifies a form bean, the ActionServlet sees if there
is one already, or creates one.
4.1) If a form bean is in play, the ActionServlet resets and populates
it from the HTTP request
4.2) If the mapping has validate set to true, it calls validate on the
form bean. If it fails, it forwards to the path specified by the input
property, and this control flow ends
5) If the mapping specifies an Action type, it is instantiated if
needed, or reused if already there
5.1) The Action's perform method is called, with the instantiated form
bean
5.2) The Action may populate the form bean, call business objects,and do
whatever else is needed
5.3) The Action returns an ActionForward to the ActionServlet

If the ActionForward is to another Action URI, we begin again, else it's
off to a JSP or something.

If the ActionForward is to a JSP
1) Jasper, or the equivalent, renders the page
2) If the Struts html tags see the ActionForm in the request (from 4),
it populate the controls from the ActionForm. Else the html:form tag
creates one, and uses its default values in its tags.

(Can't draw, but I sure can number;-)

If you just need to create a blank form (4), you can use a "continue
Action" to pass control through an Action and then out to the JSP.

 public ActionForward perform(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException {

 return mapping.findForward(request.getParameter("continue"));

 }

So in the mapping you specify the ActionForm for this instance,
validate=false, and a local forward for the JSP input form.

Re: Hidden Field in a form. Do I use struts taglib or vanilla html?

[Ted Husted]

The cleanest thing is to put the ArrayList on the ActionForm. The syntax
of the options tag is suboptimal, so you need to expose the property as
a bean. 






So, you go through an Action, and have it setup the names list. 

If there's validation involved, use the same Action as the input path,
so the list gets made again.

This also makes it much easier to retrieve the list from a database or
static class that is on the business tier.

Re: Hidden Field in a form. Do I use struts taglib or vanilla html?

[David Lauta]

Thanks for the reply,
I understand that you would like me to seperate the UI from the Model
Can you be more specific about
'The recommended control flow is to go through an Action first'
I'm trying to get a one page does it all UI - Is there a tag I should use to invoke
some kind
of preprocess action?

What I am after is populating the List boxes with data from (ultimately) EJB's
I need to decide where I am going to instantiate and initialize my EJB's ( Session
Beans )

To this point in my model I have subclassed ActionForm, Action, and ActionMapping
my struts-config.xml is:
 
  
 

 
  

   
  

 


Should I be using the ActionFormBean instead or in conjunction with the ActionForm
subclass?
>From the ActionForm I can get the ActionMapping through
ActionServlet.findMapping(String)
At what point in time is the servlet associated with ActionForm valid.

Most of my confusion comes from the order of things.
So far my model
1 Create the ActionForm  ( Servlet is null )
2 Initialize the JSP ( all form values are null )
3 Get ActionMapping Name
4 Get ActionMapping Name
5 Create another ActionForm (Servlet is null)
6 Some magic I haven't been able to trace yet
7 The JSP appears and the list boxes are filled in


It seems like I have two instances of ActionMapping and two instances of ActionForm

How should the initialization really occur?


Thanks for your attention

Re: Hidden Field in a form. Do I use struts taglib or vanilla html?

[Ted Husted]

In Struts 1.0.1, init() is called if the ActionForm is instantiated by
the JavaServer Page. In Struts 1.0, this only happens when the
ActionForm is instantiated by the ActionServlet. Of course, any default
values assigned to the fields in the ActionForm class itself will be
available in either case. The recommended control flow is to go through
an Action first, and populate the ActionForm there. Populating the
ActionForm from the JSP is a Model 1 strategy.

RE: Hidden Field in a form. Do I use struts taglib or vanilla html?

[Jon.Ridgway]

Hi,

No. You need (I think) to code it yourself. See my previous response to
'hidden tag and request object'. 

It would be nice if you could specify that you wanted your form
pre-populated. 


Jon.

Is there a method in the framework that gets invoked allowing you to

Re: Hidden Field in a form. Do I use struts taglib or vanilla ht ml?

[Ted Husted]

If the ActionForm were a business object, then you would be right in
thinking that the data is logically different. 

But since the ActionForm is a presention object, it makes perfect sense
to store the "action" here.

The purpose of the ActionForm is to store the user gestures, which then
are mapped to business objects. But the ActionForm itself is not the
"message" object. It is what we use to create a business object based on
what the user tells us. Here part of what the user is telling us is
"sendMessage".

So, add it here, just don't add it to your internal "message" object,
which probably has a sendMessage method instead.

If it helps, here are some methods that do that using reflection. Set
fills this object from another object. Populate fills another object
from this object. I have the luxury of placing these on my base business
class, but, given comparable exceptions, they would work just as well on
an ActionForm. (Hmmm.)

public void set(Object o) throws ModelException {
try {
BeanUtils.populate(this,BeanUtils.describe(o));
} catch (Throwable t) {
throw new ModelPopulateException(t);
  }
};

public void populate(Object o) throws ModelException {
try {
BeanUtils.populate(o,BeanUtils.describe(this));
} catch (Throwable t) {
throw new ModelPopulateException(t);
  }
}

If there were a mismatch between the property names, one way around that
would be to replace the call to BeanUtils.describe withy a custom
version that generated the appropriate hashmap for the target bean.

[Shri]

by having a 'HTML' hidden field, you will loose the mapping of form elements
to properties in the form bean, action class cannot access the value of it.

Hi

I want to include a hidden field in a form which I have.  I do not want
this information to be included in the formbean which is defined for
this page.  How can I do this?  Should I just use plain html



without using the html taglib supplied with struts?

RE: Hidden Field in a form. Do I use struts taglib or vanilla ht ml?

[Brett Porter]

That's an interesting design decision. I have always had a form bean and
then another bean containing the actual data. The action copies it across,
processes it, and stores it.

The reason I'd do it that way is that I imagine the message is a "business
class", and you don't really want you model "polluted" by extending an
ActionForm. Maybe I've been living in OOAD land too long though ;)

This can trip you up though - at least once I have added the form element,
added it to the bean, added it to the form bean, and forgetten to do the
setter in the action :) The way around that is probably a function in the
form bean that says "fill my business class" and "fill from a business
class". Actually, I might put that in my todo list :D

Cheers,
Brett

The data I am storing in the bean is logically different from what the 
hidden field value is,  I have a message

message
{
   string  Recipent
   string  From
   string  MessageBode
}

And the hidden field is   action=sendMessage and I didn't think that

message
{
   string  Action
   string  Recipent
   string  From
   string  MessageBode
}

would be the correct thing to do, but I am open to suggestions.  If it 
works out easier to put this extra field in my message formbean then I 
will do it.  What do you think?

Won't hurt.

You'll just have to use request.getParameter("action") in your Action to get
it.
