Hi all,
I have a ArrayList with Strings in request object and trying to populate in Jsp. Could any one give me sample code for it?. I am trying with Iterator,optionsCollection and option collection..etc but no luck.
I am setting the arrayList into request object as well setting to Form bean though we no need to do both, just for testing purpose I am doing this.
If I put Arraylist in request object without setting to FormBean how can we populate and If I set it to Form bean then how to populate?.
Note: My ArrayList have just string names not beans.
My ActionClass code :
request.setAttribute("products", newProductsList);

Assuming your ActionClass contains...
//startForm.setProducts(newProductsList); // not required
request.setAttribute("products", newProductsList);
Your JSP page can be populated by using...
<logic:iterate id="product" name="products" type="java.lang.String" >
<bean:write name="product" />
Should work now. Pls check it up.
