Getting Started with the Stripes. Framework. Emerging Technologies for the Enterprise Michael P. Redlich. March 27, Stripes is a framework that makes developing Java web applications easier. How . a PDF viewer that supports hyperlinks, it's even easier: just click the bar, and. More details about Stripes can be found here. This tutorial shows you; how to develop a simple web application using Stripes framework in Eclipse.

This makes it really easy to handle multiple submit buttons in a form! Join us in London! Stripes tags are straightforward. A sample file is included in the lib subdirectory of the Stripes download file. Suppose you have a model object that has properties which are, in turn, other model objects, such as a Person with an Address: Then we create text inputs with the name attribute that corresponds to the target property:

Stripes - Hello, World! Gobinath Loganathan 3: Stripes is an open source web application framework used to simplify Java web development. Stripes provides both View and Controllers of MVC architecture and let the developers port their Model into the system.

Comparing to Struts, Stripes is a lightweight and less configuration needed framework, but it provides almost everything provided by Struts. More details about Stripes can be found here.

Tutorial – Stripes: a lean, mean Java web framework

It runs in a JEE web container, uses minimum configuration files, and has a flexible and simple parameter binding. Stripes' ActionBean is an object that receives the data submitted in requests and processes the user's input. It both defines the properties of the form and the processing logic for the form. Stripes auto-discovers ActionBeans at deployment time by scanning the web application's classpath.

The ActionResolver. Packages init-param of the Stripes Filter in web. Resolution is an object created as a response to the processed request. A Resolution can forward to a JSP page, stream data, or return an error message.

Stripes - Hello, World!

Resolutions are returned by handler methods of ActionBeans. From the Stripes' Github page , we download the latest Stripes release.

In the lib subdirectory, we have the three JAR files that we need to include in our projects: In addition, there is also the StripesResources. Simple Stripes application The first application displays the current date. We create a new web application in NetBeans. The project has three files: In this application, we do not use StripesResources.

In the standard web. Never fear! Stripes does it for you, even on nested properties. When it gets null from a getter when binding request parameters to properties, Stripes creates a new object and sets it. So you can just add properties and let Stripes take care of the housekeeping. Finally, we just need an event handler for the submit button, which is named save: By the time the save method is called by Stripes, the parameters have been bound to the action bean properties, so we can count on the person object to be created, populated, and ready to be saved.

Well, that is not entirely true: We can easily address this with validation. Stripes offers a simple way to perform validation on user input: Continuing our Person form example; say we want to make sure that the user enters values in both the person.

Stripes - Hello, World!

We use annotations on the person property in the action bean: We can place this annotation directly on an action bean property if we are submitting a value directly to that property.

In that case, we need to place our Validate annotations inside a ValidateNestedProperties annotation, and use the field attribute to indicate which nested property we are validating.

Now, with these validations, a blank form will not cause our save event handler to be called. Submitting a blank form will result in a page as shown in the figure below Fig. This keeps your JSP code clean and tight.

Stripes comes with the following built-in validations: Writing a custom validation method is a breeze, too. Just write a method annotated with ValidationMethod. For example:.

By adding an error to the errors list, we cause Stripes to return to the form instead of calling the event handler, just like when a built-in validation fails. Finally, note that Stripes only calls the validation method if the built-in validations have passed. If the required validation fails, the custom validation method will not be called. The error messages concerning the fields being required will be shown instead.

Suppose you have an enum, Gender , as follows:. Here is how you could create a form to select one gender with radio buttons, any number of genders with checkboxes, and one gender with a select box: As you can see, the Stripes tag library makes it easy to create forms and use form controls.

Remember that the form controls automatically repopulate from previous values. Also, Stripes will automatically handle the conversion between String and our Gender enum type. By doing this, we can make sure that the user makes a selection.

We are ready to look at the action bean: The properties correspond to the name attributes that we have in the JSP. As I mentioned, Stripes converts from the incoming String to the corresponding Gender. This list will automatically contain the genders that the user has selected.

Its philosophy is that there are many excellent solutions for those tiers of an application, so it does not reinvent the wheel and does not prevent you from choosing your favorite solution for things like persistence, JavaScript widgets, and so on.

Here is a summary of more features offered by Stripes: Stripes strikes a perfect balance of powerful features, simplicity, and tight focus to give you a framework that does a lot for you without getting in your way nor suffering from feature bloat. It is easy to learn and intuitive, so you quickly become productive.

It is customizable and extendable, so you can tweak it to suit your more advanced or particular requirements. Last but not least, it has one of the friendliest communities in the open source framework space, so if you need help, write a message to the mailing list.
