Hi, I have a small jsp page that use a bean. My bean derive from a base class and i only use reference to the base class to make my code reusable. Here's my code: the bean "myBean" is already initialized with a derived bean (let's call it the DerivedBean class). <jsp:useBean id="myBean" scope="session" class="com.sample.beans.BaseBean"/> Bean value: <%= myBean.getValue() %> <BR> Bean value: <jsp:getProperty name="myBean" property="value"/> The problem is that the first line (<%= ... %>) works and return the correct value, that is, the value stored in the DerivedBean class. The other line return the value of the BaseBean instead. I cannot use polymorphism if i use the getProperty tag according to my tests. I use Tomcat 3.2 installed with Borland JBuilder 5. Can someone help me? Is this normal? I hope not... Thanks, -- Louis-Philippe Brochu lpbrochu@dra.com
