I am using springMVC and hibernate in my current j2ee project.
The view as of now consists of plain jsp, with JSTL to make things a bit simple.
Looking at the extjs project, I believe it can be used as a substitute for the view. I have been looking at the extjs docs but frankly, I am not sure how to integrate it in spring.
Does anyone have any tutorial, blog, books recomendation, to get me started on this?
Or on the other hand, if extjs would be better managed from a different java MVC framework, then please suggest the same.
Here is an example of a ProgressBar Pager integrated with Spring 3.0
It Demonstrates that Ext JS provides a helper class, XMLStore, which is automatically configured with an XMLReader which is used to read data from server.
It uses Xstream from codehaux for serialization to XML.
XStream is easily configurable with annotations,
I like to use Spring views to return JSON data. Requests arrive and handled by a ThrowAwayController or MultiActionController or annotations (depending on the version of Java) which eventually passes a model to a JsonView. There are libraries/packages that create JSON from Java objects - I recommend using one. The client is a single page web-app - generated from JavaScript when the site initially loads - and it makes requests to the server (as described above) in response to user requests. JSP and JSTL are not discarded entirely, but their role is less important.
You can have a look on http://www.jprovocateur.org (Spring + Hibernate + Ext J.S) that allows the configuration of the ext j.s views(forms and grids) using xml.

I have been working on an infrastructure project that has a myriad of pages that used in numerous flow based scenarios. I eager to use a standard framework for facilitating this flows. I have a glance on spring web flow and I realize it is difficult to deal with all of the XML stuff like flow files. Could you please tell me is there an annotation base version instead of these XML files? Or Is there any other frameworks that use annotation based approach for this purpose. Moreover, I saw Seam framework, but like Spring Web Flow it has an XML based feature. Additionally, I read some articles about Netui Page Flows. Even though it has annotation based flows, as you know it is a very old framework and discontinued now.
I use this links:
spring web flow support in intellij idea 12
Spring Web Flow Ref Book
spring web flow
As I need this xml based file for create a web flow for my JSP pages into my enterprise application, after month looking for best solutions and frameworks, finally I find Spring Statemachine for my porpuse. I put that here for someone in future that looks for object-oreinted state machine that can be used in her/his page flow.
Thank you Spring :)
I am trying to build a basic CRUD application with NetBeans 7.4, JSF, PrimeFaces and JPA using MySQL.
I have successfully done this by using the NetBeans wizards. I want to do this from scratch, no wizards.
There seems to be a lack of support for the combo of JSF, PrimeFaces and JPA. When I say "lack", I mean a full example (I might be asking too much), without using the CRUD auto-gen templates/classes AND shows actual queries coded and passed to the datatables(primefaces). YouTube is full of non-English speaking examples using Hibernate (not JPA) and other examples that show flashy GUI's with no code.
So far I understand you need an #Entity class (provides the physical build of the tables), a Controller (serializable) and the .xhtml web page to show the datatable.. what else? Also, I'm not seeing any posts or examples where queries are using with JPA/JSF and how they are tied together (in one place). I need to connect the dots here so that I can leverage JSF/JPA to create simple queries to populate my PF DataTables. I've read the blogs and I've googled the intranets until I'm blue in the face. Sending me a list of URL's to read to learn about each product is something I've already done. I get what they do independently, but am looking for the "How do they all connect" answer with maybe some basic code examples!! :)
Since version 11, PrimeFaces comes with a JpaLazyDataModel which you can use with your p:dataTable. In its simplest form to be used like:
new JpaLazyDataModel<>(MyEntity.class, () -> entityManager);

look.If you need an example about CRUD operation using JPA/EJB as Model layer and JSF as view layer,you can see the follwing example:
http://uaihebert.com/?p=834
also my own blog is based on many examples explaining this.These examples are using JPA2/EJB3 as model and JSF2 and primfaces as view you can see

Try this archetype which will create you an example and then check how it is implemented: https://github.com/ignl/happyfacescrud. You will learn about Spring, Spring security, Spring WS, JPA and Hibernate, Spring data and QueryDsl for easier querying, and custom JSF components which will make you very productive jsf developer.
I am supposed to redesign a web application that was originally created in JSP. However, I have two important requirements that this application should meet.
This new web application shall be able to keep its existing direct URL structure, that looks like this: http://existingurl.org/appname/file.jsp?id=0000000000001&optionalParams=something
It shall Support Javascript and AJAX (But I think that this one is not really a problem nowadays)
My first choice was spring MVC due to its popularity, but as far as I know the URL structure in Spring MVC would not support the file.jsp part of the URL. In Spring the URL would look like this:
http://existingurl.org/appname/file/id/0000000000001?optionalParams=something because it tends to hide the extension.
Is there any way to support this direct URL from my first requirement with Spring MVC? Or would you recommend me any other framework?
Spring mvc will absolutely let you keep your mapping. You can map it how you like!
Are there any sample / tutorial on Spring MVC with JSP without using Tag Libraries. Pure JSP.
I am not conversant with Tag Libraries and I am good with JSP. So I would like to see if there are any examples and tutorials using pure JSP without ANY tag libraries.
I don't mean to say this in a degrading manner, but if you are good with JSP, you should be able to pick up the Spring MVC tags easily. JSP, custom tags and ELs go hand-in-hand. They are created for a reason: to make your life simpler. A quick example, if you use Spring MVC's form tag, Spring MVC will automatically prefill the form fields for you based on the data you have in the model. Think about how tedious your code will be to prefill the checkboxes/radiobuttons or preselect the drop down lists.
If you are also Spring Security, the provided custom tags allow you to easily control what data to be displayed based on the user roles.
Writing all of that using pure JSP don't even make sense to me... not to mention the amount of time wasted writing less than perfect home grown solutions.
In Asp.Net MVC 2.0, at least in the beta, you could decoration your model classes with data annotation attributes and enable client side validation that leverages that criteria defined in your model data annotation attibutes. Is there anything similar for Java Spring MVC 3.0?
Is it possible to inject a component into the response pipeline that can inspect the model's annotated properties and render client side validation logic to complement the server side validation logic that is invoked prior to the controller handling the request?
Actually, there is something a little bit like it, based on the JSR-303 Bean Validation spec, which is now final and fully supported by Spring 3.0.
Recently, as part of Spring Webflow, Springsource has released Spring JS (javascript) which uses Dojo. You can use that for your client side validation. Check out this howto
Obviously, component-frameworks such as Wicket (like fraido mentioned) have better support for this kind of usecase. So if you have to implement a lot of similar usecases, that is probably a better fit for your project. However, if it is sporadic, Spring JS / Bean validation could be the way to go.
Spring MVC is a fairly low level framework. It doesn't extend to doing client side validation.
There are other Java Web frameworks that do this such as Tapestry, Wicket and JSF (IceFaces, etc). These are what I tend to call "component frameworks".
In Spring MVC 3.0 there's nothing like that at the moment. As cletus said frameworks like Tapestry (ex), Wicket (ex) and others have some sort of Client Validation that uses JavaScript to validate forms etc.
You can write your own validation Jstl taglib maybe with the help of a JS Library (jQuery, ...) and Plugins like : jQuery Validation Plugin
edit: I've just found this: Mediawidget. Maybe it's worth having a look.
It says: "Metawidget reads Bean Validation annotations and generates forms with
widgets that are pre-configured for minimum/maximum values, lengths etc."

2011-12-06: I'm just about to try it myself
2013-12-09: Update on this answer: I did try the library out, and it worked very well. It needed some tweaking (it's a prototype patch for Spring, not a finished plugin), but it was the best solution I could find at the time. Perhaps there is a new solution, or perhaps someone has finished off this prototype since I posted? If not, I can recommend this one.
Ok, this is a variation on what's already been said, but one of the big strengths of Spring-MVC is its ability to integrate with other libraries, like the different JSF variations that do give client side validation.
