sorry my previous answer was based on method calling. since this is an index called though it can be done via: http://jakarta.apache.org/struts/faqs/indexedprops.html -Tim -Original Message- From: Chen, Gin [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2003 11:42 AM To: 'Struts Users Mailing List' Subject: RE: Very simple and URGENT Tag question - Please Help btw this question was answered on the JSTL (Taglibs) list.

If you placed a Map in the context you can reference items in the Map by the key. Example would be to place a Map with a key of "ID" and some value into context. You can reference the value by calling . This is useful when you can't write a bean.

OK, you're right!! Here are the first lines from stackTrace from tomcat
log:

And here's the method definition:
public class BordereauRowWrapper
{
private B2BAction[] actions;
/**
* @return java.lang.String
*/
public String getActionDescription(int i)
{
return actions[i].getDescription();
}
}
And the jsp call:
It seems there is no property actionDescription in my class, but as you
can see it IS there!!
Thanks again

Hi Renato,
hard to say when you don't write what kind of error you got. Exception?
Or nothing shown?
Dont't you forget to add bean to context (session, request,...)?
And, maybe it's typo, but... don't you forget quotes in value attribute?

I have a bean with an indexed property, that is myBean.getItem(int i). I
can't find a way to access that property, using struts, struts-el nor
jstl. I tried the following:
Where ind is the indexId attribute of an ordinary logic:iterate struts
tag. (and c is the prefix for the core jstl tag downloaded from jakarta)
Where Am I wrong ? Thanks

If you are using jstl don't use logic-iterate; rather use then you can have or if it is straight string you can have Renato Romano wrote: I have a bean with an indexed property, that is myBean.getItem(int i).
