Say your bean name for the controller C is c.html.

If you are trying to get form values, then try the following inside the onSubmit method inside your controller C:

A a = (A) command;

a.getP(); // getP() is the getter method for the property P inside your model class A. Make sure you specify <property name="commandClass" value="A" /> in servlet.xml under the bean specification for your controller C (c.html) .

On the other hand if you are trying to pass a parameter from one controller to another then try the following:

Then you pass the parameter P with value say 'val' to the controller C by

c.html?P=val

// I think its bad programming style to pass values from a controller to another as in spring framework values are usually passed from model to view.
