If you have a class with
String getTheValue() // you can read the property "theValue".
void setTheValue(String x) // you can set the property "theValue"
If it's an array or a java.util.List you can access it using myobject[i]
If it's a java.util.Map you can access the values using myobject[key]
And you also can access the pairs name-value using it as a collection with the forEach tag:
<c:forEach items="myMap" var="pair">
<!-- here pair is a java.util.Map.Entry and you can use pair.key and pair.value -->
</c:forEach>
It it's NOT a Map you can access properties using ['propertyname'], so you can access:
myobject['theValue'] for the first example in this mail (note this gives you the capability to access dinamically the properties of a Bean).
At last, you can instantiate the objects in your JSP stating their scope.
You can:
<jsp:useBean name="x" class="org.myproject.MyClass" scope="page"/> <!-- for creating an object for each page --->
<jsp:useBean name="x" class="org.myproject.MyClass" scope="session"/> <!-- for creating an object for each session --->
(check the useBean sintaxis, I'm not sure of it right now)
Good luck.

Hi,
I saw some examples to access standard java bean properties from JSTL expression language on JSP page. I am wondering is there any way to access regular java class methods from JSTL expression?
Now in the JSP, I am trying to access a Java class, which has a business method return a string value. That java class is not a java bean class. Can someone tell me how to do that?
Thanks
