News

The last time AppFuse had an update done to its look and feel was in way back in 2006. I've done a lot of consulting since then, which has included a fair bit of page speed optimization, HTML5 development and integrating smarter CSS. It was way back in '05 when we first started looking at adding a CSS Framework to AppFuse. It was Mike Stenhouse's CSS Framework that provided the inspiration and my CSS Framework Design Contest that provided its current themes (puzzlewithstyle, andreas01 and simplicity).

Since then, a lot of CSS Frameworks have been invented, including Blueprint in 2007 and Compass in 2008. However, neither has taken the world by storm like Twitter Bootstrap. From Building Twitter Bootstrap:

A year-and-a-half ago, a small group of Twitter employees set out to improve our team’s internal analytical and administrative tools. After some early meetings around this one product, we set out with a higher ambition to create a toolkit for anyone to use within Twitter, and beyond. Thus, we set out to build a system that would help folks like us build new projects on top of it, and Bootstrap was conceived.
...
Today, it has grown to include dozens of components and has become the most popular project on GitHub with more than 13,000 watchers and 2,000 forks.

The fact that Bootstrap has become the most popular project on GitHub says a lot. For AppFuse.next, I'd like to integrate a lot of my learnings over the past few years, as well as support HTML5 and modern browsers as best we can. This means page speed optimizations, getting rid of Prototype and Scriptaculous in favor of jQuery, adding wro4j for resource optimization and integrating HTML5 Boilerplate. I've used Twitter Bootstrap for my Play More! app, as well as some recent client projects. Its excellent documentation has made it easy to use and I love the way you can simply add classes to elements to make them transform into something beautiful.

Last week, I spent a couple late nights integrating Twitter Bootstrap 2.0 into the Struts 2 and Spring MVC versions of AppFuse. The layout was pretty straightforward thanks to Scaffolding. Creating the Struts Menu Velocity template to produce dropdowns wasn't too difficult. I added class="table table-condensed" to the list screen tables, class="well form-horizontal" to forms and class="btn primary" to buttons.

I also added validation errors with the "help-inline" class. This is also where things got tricky with Struts and Spring MVC. For the form elements in Bootstrap, they recommend you use a "control-group" element that contains your label and a "controls" element. The control contains the input/select/textarea and also the error message if there is one. Here's a sample element waiting for data:

<div class="control-group">
    <label for="name" class="control-label">Name</label>
    <div class="controls">
        <input type="text" id="name" name="name">
    </div>
</div>

Below is what that element should look like to display a validation error:

<div class="control-group error">
    <label for="name" class="control-label">Name</label>
    <div class="controls">
        <input type="text" id="name" name="name" value="">
        <span class="help-inline">Please enter your name.</span>
    </div>
</div>

You can see this markup is pretty easy, you just need to add an "error" class to control-group and span to show the error message. With Struts 2, this was pretty easy thanks to its customizable templates for its tags. All I had to do was create a "template/css_xhtml" directory in src/main/webapp and modify checkbox.ftl, controlfooter.ftl, controlheader-core.ftl and controlheader.ftl to match Bootstrap's conventions.

Spring MVC was a bit trickier. Since its tags don't have the concept of writing an entire control (label and field), I had to do a bit of finagling to get things to work. In the current implementation, Struts 2 forms have a single line for a control-group and its control-label and controls.

<s:textfield key="user.firstName" required="true"/>

With Spring MVC, it's a bit more complex:

<spring:bind path="user.firstName">
<fieldset class="control-group${(not empty status.errorMessage) ? ' error' : ''}">
</spring:bind>
    <appfuse:label styleClass="control-label" key="user.firstName"/>
    <div class="controls">
        <form:input path="firstName" id="firstName" maxlength="50"/>
        <form:errors path="firstName" cssClass="help-inline"/>
    </div>
</fieldset>

You could probably overcome this verbosity with Tag Files.

Figuring out if a control-group needed an error class before the input tag was rendered was probably the hardest part of this exercise. This was mostly due to Bootstrap's great documentation and useful examples (viewed by inspecting the markup). Below are some screenshots of the old screens and new ones.

Check out the full set on Flickr if you'd like a closer look.

I can't thank the Bootstrap developers enough for helping me make this all look good. With Bootstrap 2 dropping this week, I can see myself using this more and more on projects. In the near future, I'll be helping integrate Bootstrap into AppFuse's Tapestry 5 and JSF versions.

What do you think of this CSS change? Do you change your CSS and layout a fair bit when starting with AppFuse archetypes? What can we do to make AppFuse apps look better out-of-the-box?

Update: I updated AppFuse to the final Bootstrap 2.0 release. Also, Johannes Geppert wrote a Struts 2 Bootstrap Plugin. I hope to integrate this into AppFuse in the near future.

Before the holiday break, I spent some time upgrading AppFuse to use the latest releases of Spring and Spring Security. I started with Spring Security in early December and quickly discovered its 3.1 XSD required some changes. After changing to the 3.1 XSD in my security.xml, I had to change its <http> element to use security="none" instead of filters="none". With Spring Security 3.0.5, I had:

<http auto-config="true" lowercase-comparisons="false">
    <intercept-url pattern="/images/**" filters="none"/>
    <intercept-url pattern="/styles/**" filters="none"/>
    <intercept-url pattern="/scripts/**" filters="none"/>

After upgrading to 3.1, I had to change this to:

<http pattern="/images/**" security="none"/>
<http pattern="/styles/**" security="none"/>
<http pattern="/scripts/**" security="none"/>

<http auto-config="true">

The next thing I had to change was UserSecurityAdvice.java. Instead of using Collection<GrantedAuthority> for Authentication's getAuthority() method, I had to change it to use >Collection<? extends GrantedAuthority>.

Authentication auth = ctx.getAuthentication();
Collection<? extends GrantedAuthority> roles = auth.getAuthorities();

Lastly, I discovered that SPRING_SECURITY_CONTEXT_KEY moved to HttpSessionSecurityContextRepository. Click here to see the changelog for this upgrade in AppFuse's FishEye.

You can read more about what's new in Spring Security 3.1 on InfoQ. I'm especially pumped to see http-only cookie support for Servlet 3.0. I discovered Spring Security didn't support this when Pen-Testing with Zed Attack Proxy.

Upgrading to Spring Framework 3.1
Compared to the Spring Security upgrade, upgrading to Spring 3.1 was a breeze. The first thing I discovered after changing my pom.xml's version was that Spring Security required some additional exclusions in order to get the latest Spring versions. Of course, this was communicated to me through the following cryptic error.

-------------------------------------------------------------------------------
Test set: org.appfuse.dao.LookupDaoTest

	at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109)

Without these additional exclusions, Spring Security pulled in Spring 3.0.6. I had to exclude spring-expression, spring-context and spring-web from spring-security-taglibs to get the 3.1.0.RELEASE version of Spring.

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
    <version>$\{spring.security.version}</version>
    <exclusions>
        <exclusion>

        </exclusion>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>

        <exclusion>

            <artifactId>spring-web</artifactId>
        </exclusion>
    </exclusions>
</dependency>

I also had to exclude spring-context from spring-security-config and spring-context and spring-expression from spring-security-core. Isn't Maven wonderful?

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>

        </exclusion>
    </exclusions>
</dependency>

After making these changes, I got a bit further, but ended up being blocked by a bug in Tapestry 5's Spring support. Basically, after upgrading to Spring 3.1, I started seeing the following error:

java.lang.RuntimeException: Service id 'environment' has already been defined by 
org.apache.tapestry5.services.TapestryModule.buildEnvironment(PerthreadManager) 

Luckily, I was able to easily fix this with advice I found on Tapestry's mailing list. Unfortunately, even though I submitted a fix on December 15th, it didn't make it into Tapestry's 5.3.1 release on December 21st. As soon as Tapestry 5.3.2 is released, I hope to get the AppFuse's build passing again (it's currently failing).

I hope this article helps you upgrade your AppFuse-started applications to the latest versions of Spring and Spring Security. Over the next few weeks, I'll be exploring many of Spring 3.1's new features and implementing them as I see fit. Right now, I'm thinking environments/profiles, Servlet 3 / Java 7 support and Hibernate 4 support. These seem to be the best new features to learn about for my talk in a few weeks.

The AppFuse Team is pleased to announce the release of AppFuse 2.1. This release includes upgrades to all dependencies to bring them up-to-date with their latest releases. Most notable are JPA 2, JSF 2, Tapestry 5 and Spring 3. In addition, we've migrated from XFire to CXF and enabled REST for web services. There's even a new appfuse-ws archetype that leverages Enunciate to generate web service endpoints, documentation and downloadable clients. This release fixes many issues with archetypes, improving startup time and allowing jetty:run to be used for quick turnaround while developing. For more details on specific changes see the release notes.

What is AppFuse? AppFuse is an open source project and application that uses open source frameworks to help you develop Web applications with Java quickly and efficiently. It was originally developed to eliminate the ramp-up time when building new web applications. At its core, AppFuse is a project skeleton, similar to the one that's created by your IDE when you click through a wizard to create a new web project. If you use JRebel with IntelliJ, you can achieve zero-turnaround in your project and develop features without restarting the server.

Release Details
Archetypes now include all the source for the web modules so using jetty:run and your IDE will work much smoother now. The backend is still embedded in JARs, enabling you to choose with persistence framework (Hibernate, iBATIS or JPA) you'd like to use. If you want to modify the source for that, add the core classes to your project or run "appfuse:full-source".

AppFuse comes in a number of different flavors. It offers "light", "basic" and "modular" and archetypes. Light archetypes use an embedded H2 database and contain a simple CRUD example. Light archetypes allow code generation and full-source features, but do not currently support Stripes or Wicket. Basic archetypes have web services using CXF, authentication from Spring Security and features including signup, login, file upload and CSS theming. Modular archetypes are similar to basic archetypes, except they have multiple modules which allows you to separate your services from your web project.

AppFuse provides archetypes for JSF, Spring MVC, Struts 2 and Tapestry 5. The light archetypes are available for these frameworks, as well as for Spring MVC + FreeMarker, Stripes and Wicket. You can see demos of these archetypes at http://demo.appfuse.org.

For information on creating a new project, please see the QuickStart Guide.

If you have questions about AppFuse, please read the FAQ or join the user mailing list. If you find any issues, please report them on the mailing list or create an issue in JIRA.

Thanks to everyone for their help contributing patches, writing documentation and participating on the mailing lists.

We greatly appreciate the help from our sponsors, particularly Atlassian, Contegix, JetBrains, and Java.net. Atlassian and Contegix are especially awesome: Atlassian has donated licenses to all its products and Contegix has donated an entire server to the AppFuse project.

The AppFuse Team is pleased to announce the 2nd milestone release of AppFuse 2.1. This release includes upgrades to all dependencies to bring them up-to-date with their latest releases. Most notable are Spring 3 and Struts 2.1. This release fixes many issues with archetypes and contains many improvements to support Maven 3.

We've recently added some some new features to the AppFuse project. The first is we've installed FishEye and Crucible (a code review tool) on AppFuse's server at Contegix. We've used FishEye in the past, but now we have it on our own servers. You can view it at:

The 2nd news item is that the good folks at Mark Logic (primarily Jason Hunter) has setup a kick-ass mailing list archive for us at:

This is an easily searchable set of archives and goes all the way back to when our mailing list started back in March 2004. In the future, they hope to provide RSS/Atom feeds and allow posting (like Nabble does). I've added a link to these archives to the mailing list page.

The good folks at Atlassian have written a nice tutorial on integrating Crowd with AppFuse and Acegi to create a nice SSO solution. Crowd is a web-based single sign-on (SSO) tool that simplifies application provisioning and identity management. The AppFuse project uses it to maintain a single user store for JIRA, Confluence (this site), and Bamboo. It's worked awesome for us.

The AppFuse Team is pleased to announce the release of AppFuse 2.0.1. This release squashes a number of bugs and includes an upgrade to Spring 2.5. To learn more about Spring 2.5's features, see InfoQ's What's New in Spring 2.5: Part 1 article.
