Struts - accessing the ActionForm bean in JSP

[Agent86]

Hi,

How do you access the ActionForm in the associated JSP (in java code)?

I know i can DISPLAY with:
<bean:write name="myform" property="myproperty"/>

but I would like to do something like:

<%= (myform.myIntProperty + 5) %>

Thanks !

Maybe like this.

<bean:define id="myIntProperty" name="myForm" property="myIntProperty"
type="java.lang.Integer" />

<%= myIntProperty.intValue() + 5 %>

Maybe like this.

<bean:define id="myIntProperty" name="myForm" property="myIntProperty"
type="java.lang.Integer" />

<%= myIntProperty.intValue() + 5 %>

This should work better

<bean:define id="myform" name="myForm" type="mypackage.MyForm" />

<%= (myform.myIntProperty + 5) %>

The point being that there is no java object without defining it somehow.
The form is request.getAttribyte("myform") or session.getAttribute
("myform")

<cut value="${myForm.myProperty + 5}" />

Thanks a lot to both of you !

One More question:

<cut value="${myForm.intDummy + 5}" /> works fine with an integer
property.

What if I want to transform a String ?

<cut value="${myForm.strDummy + "__"}" /> does not work.

How should I do that ?

Try single quotes inside the expression. The nested double-quotes are
going to confuse the parser:

<cut value="${myForm.strDummy + '__'}" />
