How to use array of beans in jsp

Hi everybody, I am Chaitanya, I have a jsp to which an array of beans is passed as a request attribute. I don't know how to declare that bean and how to index. This is what I have written and I am getting an error.

Please help me. Thank you all in advance.

Impossible. Request parameters can only be strings. You'll need to explain what you mean by this.

Do you really mean a scoped variable?

Oops, I am sorry, its not a request parameter, its a request attribute actually.

Can I make a couple of suggestions, firstly you are not required to use the <jsp:useBean .../> or <jsp:getProperty... /> tags if you are using EL which you seem to be using.

Next I'd change this line

In this firstly you have not declared the items attribute which is required, this must be any kind of collection or an array of beans that you want to output. Also you do not need that begin/end/step in your example because as default it begins at 0, ends at the end of the array/collection and steps by 1.

Hope this helps.

Thank you Mr. Clark, I ll check whether this will work and come back soon.

Hi Mr. Clark, that one worked, I have one more doubt, I want the index also, can please tell me how to get the index of each bean.

Thank you in advance. Have a nice day.

Check the varStatus attribute of the forEach tag.

Hi Christophe, I want to do like this

Is there any way?

For now I declared another method in the bean, called setIndex(byte index)

Then I am getting the index in the jsp as ${bean.index}
