Struts Form Population

[Paul Benedict <pa...@yahoo.com>]

When struts auto populates the form, does it look for set methods? And  does it check that the methods are public? For instance, if the "foo"  parameter comes in and my setFoo method is protected or private, will  it ignore it?

Hi Paul,

The question is really what will BeanUtils do because Struts uses 
BeanUtils to populate the form.

Looking at the docs, I see this:

java.lang.IllegalAccessException - if the caller does not have access to 
the property accessor method
java.lang.IllegalArgumentException - if bean or name is null
java.lang.reflect.InvocationTargetException - if the property accessor 
method throws an exception
java.lang.NoSuchMethodException - if an accessor method for this propety 
cannot be found

...in the docs for PropertyUtilsBean.setProperty(), which is I believe 
what is ultimately used to set a given property.  So, my bet is you'd 
get IllegalAccessException thrown, or possibly NoSuchMethodException.

Then again, there *is* IIRC some special handling for read-only 
properties, and I would think that is determined by whether there is an 
accessible getter.

Well, I suppose in the end I'm not really sure what the answer is 
without actually testing it, but BeanUtils is where you should be 
looking in any case :)

You can do what Frank suggests, which I agree with in total, or you can just
try it and see what happens.  Probably is quicker to try it and see than to
ask on this list.
