Sorry, myMethod only executes if it's some bean property accesor, otherwise
it's an error (EL is for bean evaluation, only, at least in a <c:out>). So
the bean constructor approach is the working one.

In the first case, the code must be in "myMethod", in the second the code
must be in the constructor (or in a static block inside the class ;-) but

I thing the modern approach is a custom tag -
Custum functions are OK but are restricted to static methods. It is not
easy to give these functions access to the page context. Custom tags have
access to this data.

Or make a bean that calls the code on its creation and
<jsp:useBean id="aux" scope="page" class="MyCallingBean" />

Another option is to put the code into a servlet and use

Hi
This is my suggestion : you put all your code in a method of your bean MyUseBean.java (for example public void getMyMethod() {})
Then, simply put in your JSP : ${myUseBean.myMethod}
