Using JSP struts tag logic:iterate
Hi, I'm a bit confusing using the jsp struts tag logic:iterate. Here is my problem. In my business logic I've created an object (let's call it objA) that contains a Hashtable which itself contain a list of objects (objB) . The Hastable object (hTable) can be accessed through getter and setter from objA. I want now to display as a table the property prop of all objB objects contained in the Hashtable hTable (prop is a String and can be accessed through getter and setter from objB. Before launching the jsp I've put objA in the HTTP request. Then I've coded the following in the Jsp : jsp:useBean id=objA class=ObjA scope=request/jsp:useBean logic:iterate name=objA property=hTable id=objB indexId=ind Next element is bean:write name=objB property=prop / [bean:write name=ind/] /logic:iterate Coding this, I get the following error : [Servlet Error]-[No getter method for property prop of bean objB]: I tried then to code : jsp:useBean id=objA class=ObjA scope=request/jsp:useBean logic:iterate name=objA property=hTable id=objB indexId=ind type=ObjB Next element is bean:write name=objB property=prop / [bean:write name=ind/] /logic:iterate In this case I get the following error : [Servlet Error]-[JSP 1.2 Processor]: java.lang.ClassCastException: java.util.Hashtable$Entry Can anyone tell me what I am doing wrong please ? Thanks for your help Jean-Michel Auguste
Re: Using JSP struts tag logic:iterate
Thanks for your help Nico, As you recommend I've checked into my ObjB class and the property prop looks well formed : - prop is of type String - there is only one getter (getProp() ) and one setter (setProp(String p) ) - getProp() is public As I mentionned in my first append, I used two ways to code the logic:iterate tag. I can understand the first error message as there is no mention anywhere of the type of objB (as objB is stored as an Object type in the Hashtable). But I don't understand the second error message (invalid Cast) as I specify the type for objB. - Original Message - From: Nicolas De Loof [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Thursday, March 27, 2003 11:27 Subject: Re: Using JSP struts tag logic:iterate You don't need jsp:useBean as struts tags look into scope themself.

Re: Using JSP struts tag logic:iterate
Hi Nicolas, After some reading, I wrote the following code that works pretty well... logic:iterate name=objA property=hTable id=objB Next element is bean:write name=objB property=value.prop / [bean:write name=objB property=key /] /logic:iterate I don't fully understand how the cast from Object to ObjB is performed but it works Thanks for your help. - Original Message - From: Nicolas De Loof [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Thursday, March 27, 2003 12:24 Subject: Re: Using JSP struts tag logic:iterate YOu can read this on struts-logic doc : Normally, each object exposed by the iterate tag is an element of the underlying collection you are iterating over.

Imbeding a struts tag in another ?
Hi, I'm having the following problem. I need to display a radio button in a Jsp but the attribute value of this radio button must be set with the property of a bean located in the request.
