An EL tutorial from Sun: aracer.mobi JSPIntro7. html. • A list of Struts tags that have not been EL-enabled because they have. This is a tutorial for the Struts framework. It consists of a small application which is developed step by step. It can display books in the browser, new books can be.

Ce type de tutorial va être seulement des images et de code source des pages utilise . This is a blank Struts configuration file with an example. To let user download a file from your Struts web project, you have to inform . prefix="html"%> Download file from server - aracer.mobi You are lucky to use struts because Struts provides a built-in action called Set the contentType = “application/pdf” for dowloading PDF file.
This fact is also very great for unit testing. If you remember back the time in Cocoon 2 with the so called "blocks" - wow, what a progress this project has made. Cocoon 3 is embeddable. Basically what you can see here how I create a NonCachingPipeline. You could say this is a Pipeline without any tricks or treats.
It is basic. Good that we have a bunch of them! Cocoon 3 checks if there is such a consumer following for you and links the gory details.
Finally I have added a serializer. Now the fun can begin. Call setup with an OutputStream.
With execute you start the execution of this pipeline. Of course you can use this stream in memory and you don't need to write this to disk as I do for several reasons. As you can see, Cocoon 3 is all about streaming. This is pretty fast and easy to develop. Together with the streaming result type of Struts this was implemented in pretty short time.
And the good thing is, I was even able to write JUnit tests without any pain. Apache Cocoon Java Open Source.
So, now how should I integrate this into my Struts application? The latest version of the dependencies can be found here. The CarAction has two fields — carName used for storing the input from the user and carMessage used for storing the custom message to be displayed:. This is a content of the input. StrutsPrepareAndExecuteFilter is the controller, which will intercept all incoming requests.
We need to register the following filter in the web. The Namespace is used for logical separation of request URI for different action classes; we need to include this value in our request. Furthermore, the Action tells the actual end point of the request URI which will hit our Action class.
The action class consults CarMessageService and initializes the value of another member variable carMessage.
Finally, the Result has two parameters. First one, name, specifies the value which our Action class will return; this value is returned from the execute method of Action class. The Struts Tags reduce effort by reducing code.
So not only is there less code, but there is more utility. In about the same amount of code as two conventional controls, the Struts Tags can create an entire data-input form with eight controls.
Not only is there less code, but the code is easier to read and maintain. Struts Configuration in a Nutshell A web application uses a deployment descriptor to initialize resources like filters and listeners. The web deployment descriptor is formatted as a XML document and named web.
Struts can either initialize its resources by scanning your classes using Java packages declared in this web. These resources include action mappings, to direct input to server-side Action classes, and result types, to select output pages.
