Hi,
I'm new to Struts and am trying to get the hang of it.

Here's what I am trying to do.

In my action class

Collection b_list = DM.findAllById();
request.setAttribute("fields1", b_list);

Here, DM is a java class and the findAllById method returns an ArrayList. Each item in the array list is lets say of the type: abc(String id, String value) with getId() and getValue() implemented in that class.

Now in my JSP:

I do not have a form bean asssociated with it. Infact, I do not want to submit any data from this. I simply want to show a drop down menu box with all items from the collection.

But I presume I need to create a bean using the object I have added to the request object.

So, I'm trying to do this: (i dont know if I need property="id" for html:select tag as I dont want to submit anything.

<logic

resent parameter="field1">
<bean

arameter id="mylist" name="field1"/>
<html:select property="id">
<html

ptionsCollection label="id" name="myList" value="value"/>
</html:select>
</logic

resent>

OR

<html

ptions collection="myList" property="value" labelProperty="id"/>

instead of html

ptionsCollections

Is this correct? I cant get it to work. Am I missing something?

Here is what I've coded which is working for something similar to yours:

And in my Action class's execute method that prepares the collection:

Thnaks for your reply:

However, I do not want to submit any info from the jsp. My jsp (a popup actually) simply uses a javascript function to update something in the previous JSP.

Also, cant I simply fdo away with LabelValueBean and pass the Collection in the request object and create a bean on the fly using the Collection of objects in the JSP and use it?

You can of course remove the html:form tag.

You can use your own bean class as you wish.

I do not have a bean associated with this JSP. So, am I correctly creating a bean on the fly for Struts to use using the tags and theCollection from the request object?

If I understand what you mean correctly, yes.

Why don't you try it out yourself to see if it works ? It's definitey more productive than just waiting for answers that may or may not be concise to what your question means. It shouldn't take more than a few line of codes anyway.

Good luck ! Appreciate if you could post the outcome.
