Re: [Stripes-users] Where does variable 'contacts' came from in the book about Stripes?

[VANKEISBELCK Remi]

Hi,

When you write this in EL :

${actionBean.contacts}

It actually looks for a JavaBean property named "contacts" on an object
named "actionBean" bound to a JSP scope (here, request). In that case, it
ends up invoking "getContacts".

Cheers

[Stripes-users] Where does variable 'contacts' came from in the book about Stripes?

[Tika Spic]

I'm currently only reading the book "Stripes: ...and Java web development
is fun again".
Since I'm not new to web development, I'm able to read this book without
practicing in editor.

I have spot a problem on page 47 in the following line:


What is this reference "contacts"? It is not explicitly declared in the
action bean. It does exist only in this method name:

public List getContacts() {
   return contactDao.read();
}

So, was the "contacts" reference accidentally dropped from the code or
Stripes perhaps uses implicit declarations according to some naming
conventions, e.g. method naming? I believe that it was accidentally dropped,
since in the first chapter a "date" reference was used in similar way, but
now I'm not sure that there is not some kind of implicit declarations since
Stripes forces convention over configuration.

Hi Tika,

That reference is just standard JSP EL notation that references a getter
method on a bean.  So "actionBean.contacts" will execute the method
actionBean.getContacts().  This is a common way that Java/JSP web
applications call into Java classes in order to execute accessor (getter)
methods.
