Question

I needs to populate values for listboxes , textboxes .. almost all the form input elements from my servlet . Because sending the object to the JSP page and populating the values for the input elements there (using any tag libraries JSTL) i found it difficult.

Is there anyway for setting all the Input Element values from the servlet itself? For example if i needs to set the value for textfield , then in my servlet

TextFieldBean tf = new TextFieldBean("userName");
tf.setValue("Test");

In my jsp page

<input type="text" name="userName">

That’s what all MVC frameworks (that I know about) allow doing. Here’s an example with Stripes:

// in the Stripes action:
public Resolution displayForm() {
    this.userName = "Test";
    return new ForwardResolution("/displayForm.jsp");
}

// in the JSP
<s:form beanClass="com.foo.bar.SubmitFormAction" method="post">
    User Name : <s:text name="userName"/>
</s:form>

MVC frameworks have their own learning curve, but they offer huge services (data binding being one of them). Pick one and learn: Stripes, Spring MVC, Play, … there are dozens of them. I like Stripes for its simplicity and good design.
