Accessing String Array with struts tags

[bryan nelson]

Greetings,

What I want to do appears to be quite simple, but it is not working out that way.

I'm using Struts 1 and have a restriction to not use any JSTL or EL...only struts tags (it's a long story).

Short version:
I have an String array in the request with only one value: (stringArray = [oneValue])
And I want to display this "oneValue" on the page.

More details:
In actuality I'm passing an html:hidden value from the previous page which is coming over as a single object in a String array. I need to access this hidden value on the next page.

Thanks for your help!

Try using logic iterator to iterate through the array and then bean write to print the value of the element.

Something like this should work:

<%@taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<%@taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>

<logic:iterate name="formBean" property="strArray" id="strArrayId">
	<bean:write name="strArrayId"/>
</logic:iterate>

Hmm...good idea. I actually thought that was going to work, but it didn't.

I do have a getter/setter in my form as well, just so everyone knows.

The interesting thing is that if I do this I receive the expected "oneValue":

<%= request.getParameter("medicareCaregiverHomeFormActionValue") %>

So I know that the information is there.

Any other ideas?

Hello all.

Looks like the answer is found with this bean:parameter tag:

<bean:parameter name="strArray" id="whatever" />

Alternatively, I could check for the variable's existence using a present tag with the parameter attribute:

<logic:present parameter="strArray" scope="request">

Do stuff...

</logic:present>

I hope this helps someone else out in the future when dealing with request parameters and/or hidden form fields in struts...

Use session or request either one set the value and get where ever you want...
Like

HttpSession session = request.getSession(true);
session.setAttribute("anyString",anyString);

Get wherever you want in jsp

HttpSession session = request.getSession(true);
String s = session.getAttribute(anyString);
out.print(s);
