Re: [Stripes-users] Where does variable 'contacts' came from in the book about Stripes?
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. -- Rick On Wed, Dec 23, 2015 at 11:10 AM, Tika Spic wrote: > 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"?

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