Java Architecture
HOw can I print an ArrayList in a JSP page?

I wanna print an Arraylist in a jsp page. what is the code and where should I put it in a jsp page. and how can I call the arraylist from the java class. I am using javaEE. And the project is based on 3 layer architecture. The arraylist I want to access is in web layer.Thanks for your helps.

There are several ways to do this. One of the more common ways to do this is through the use of Jakarta Commons Libraries -- specifically there JSTL (JavaServer Pages Standard Tag Library)

http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html

More specific to your question, you would iterate through the ArrayList and get the instance of the object or value you wanted to print on each iteration.

For example:

for(int i = 0; i < MyArrayList.length(); i++) {
System.println(MyArrayList[i].MyValue.toString());
}
