James,
Thanks for your response. But I don't think I did make the case clear
enough. So, let me give it another try.
My beans are in package com.xxx.domain
com.xxx.domain
abstract class Foo { // Notice: this class has the default package access
//modifier.
private String firstName ;
private String lastName ;
...... Public Getters/Setters ....
}
Now child class in the same package com.xxx.domain
com.xxx.domain
public class Bar extends Foo { // Notice: this class has "public" access
modifier
private String abc ;
...... Public Getter/Setter ....
}
Out side of com.xxx.domain package, I have no problem creating Bar and at
The same time accessing Foo's, Bar's parent, properties.
For Example:
Public class BarActionForm extends ActionForm {
Private Bar bar ;
...... Public Getter/Setter .....
}
public class BarAction extends Action {
public ActionForward execute( ...., ActionForm form, .... ) {
Final BarActionForm barForm = (BarActionForm) form ;
barForm.getBar().setFirstName( "myFirstName" ) ; // no
problem
// accessing Bar's parent properties.
return mapping.findForward("success") ;
}
}
You see, I have no problem access Foo's properties from a Bar instance
inside my BarActionForm instance.
However, the problem is inside my JSP, where I have the BarActionForm binded
To an action mapping of my html's form tag. Accessing Foo's properties with
EL will result with IllegalAccessException. You see, this is clearly a bug
in commons-el.
For example in my JSP:
......
<html:form action="/myActionMappingPath" > <!-- this mapping has "myForm",
BarActionForm, bind to it -->
....
<html:text property="bar.firstName" /> <!-- this is where I had the
IllegalAccessException -->
....
</html:form>
I hope this would make it clear that this is a bug. I've search the commons
archive and nothing that I found related to this issue.
Thanks for any help,

Hi,
I am accessing a nested bean property via EL and getting a
java.lang.IllegalAccessException:
java.lang.IllegalAccessException: Class org.apache.commons.el.ArraySuffix
can not access a member of class com.xxx.patron.domain.BasePerson with
modifiers "public"

at
org.apache.jsp.html.portlet.patron.PatronDetails_jsp._jspService(org.apache.
jsp.html.portlet.patron.PatronDetails_jsp:102)
my bean has the default package access modifier, but its properties are
declared "public". I think this is bug with the commons.el package.
Can someone verify if this is true? If it is a bug. Can someone tell when is
the next release that will have a fix for this bug?
Thanks for any help,
