My understanding is that any method signatures which match form input parameter
names will be called within the bean with the value of the corresponding form
parameter. I am not sure if case is significant. The asterisk means "call any
bean setter methods for attributes which match form input parameter names".
Eg; if your bean has;
public String getName()
public void setName( String )
public int getColour()
public void setColour( int )
Then if your jsp is called with form parameters containing;
name="zaphod"
colour=turquoise
then the setName() method of myBean shall be called with the value "zaphod", and
the setColour method shall be called with the value "turquoise". I am not sure
if this works only with Strings, I do not know (off of the top of my head, would
be easy to test) whether if you had;
int getAge() and void setAge( int age), whether or not the setAge() method would
be called with any equivalent form parameters automatically converted to ints
(although my hunch is ... probably not).
Hope this helps,
regards
Dave Young
