Sorry if I'm late at getting you an answer.
But I hope others might find this helpful in the future as well.
If you follow the trail from the struts-example, you'll find just such an
example of what you are trying to do:
----------------------
struts-config.xml
----------------------
<action-mappings>
<!-- Edit user registration -->
<action path="/editRegistration"
type="org.apache.struts.webapp.example.EditRegistrationAction"
attribute="registrationForm"
scope="request"
validate="false">
<forward name="success" path="/registration.jsp"/>
</action>
----------------------
org.apache.struts.webapp.example.EditRegistrationAction
----------------------
163 form = new RegistrationForm();
164 if ("request".equals(mapping.getScope()))
165 request.setAttribute(mapping.getAttribute(), form);
166 else
167 session.setAttribute(mapping.getAttribute(), form);
/*
*Notice line 165 and line 167, the mapping.getAttribute is getting
"registrationForm" from above in the struts-config.xml and storing the form
in the request by that name.
* Now assuming that all goes well (the user filled in the form correctly),
then we go to our jsp.
*/
201 }
202 return (mapping.findForward("success"));
203
----------------------
registration.jsp
----------------------
// Here the current bean instance is set into the pageContext by the name
"subscription"
143 <logic:iterate id="subscription" name="user"
property="subscriptions">
144 <tr>
/* Then, down here we try to create our link tag, html:link works fine for
most
* cases, however, we need have a special case.
* Personally, I use a custom tag every time I need to pass an id to another
action
* This works great for me because most of my detail records are unique by
their id and not
* by some compound key
* Basically, it appends "id=n" where n is the id of the database record
* that I am using/changing
*/
158 <app:linkSubscription page="/editSubscription.do?action=Delete">
159 <bean:message key="registration.deleteSubscription"/>
160 </app:linkSubscription>
/* app is defined as a custom tld. linkSubscription is of type
* org.apache.struts.webapp.example.LinkSubscriptionTag
*/
----------------------
org.apache.struts.webapp.example.LinkSubscriptionTag
----------------------
173 Subscription subscription = null;
174 try {
175 subscription = (Subscription) pageContext.findAttribute(name);
176 } catch (ClassCastException e) {
177 subscription = null;
178 }
/*
* Notice here that we attempt to get the form from the pageContext.
* the variable called "name" is set to a default value of "subscription"
* in this class. You can have given it any name you like
* by changing it in the logic:iterate or if you are *not* within an
iteration,
* by adding name="myName" to the app:linkSubscription tag in
registration.jsp
*
* I hope that this provides some insight into writing your own custom
(struts) tags.
* They are really quite flexible and powerful.
*
* As you build your application, try to think ahead and consider every
possible use
* of a new tag, that will provide for better reuse and it will make it more
maintainable
* for the next guy (or gal).
