If you want to deploy your app to the default ROOT context of JBoss AS7, you have to modify first your standalone.xml. Otherwise, you will raise this exception :
Caused by: java.lang.IllegalArgumentException: Child container with name already exists
By default, AS7 has an application already deployed to / context.
To fix this, set your enable-welcome-root="false" to enable-welcome-root="true". Which finaly gives you :
<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<virtual-server name="default-host" enable-welcome-root="true">
<alias name="localhost"/>
<alias name="example.com"/>
</virtual-server>
</subsystem>
That’s all 
WARNING: clock of the subversion server appears to be out of sync. This can result in inconsistent check out behavior.
This message seems pretty clear, to fix this we have to configure ntp. Let’s install the required packages :
apt-get install ntp ntpdate
vim /etc/ntp.conf
add server ntp.belnet.be
# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will
# pick a different set every time it starts up. Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
#server 0.debian.pool.ntp.org iburst dynamic
#server 1.debian.pool.ntp.org iburst dynamic
#server 2.debian.pool.ntp.org iburst dynamic
#server 3.debian.pool.ntp.org iburst dynamic
server ntp.belnet.be
...
Restart ntp,
/etc/init.d/ntp restart
You can check your configuration and see the servers with which you are synchronized with the following :
ntpq -p
remote refid st t when poll reach delay offset jitter

Since version 6.9, NetBeans offers the possibility to work with OSGi bundles. The creation of the project is relatively simple. You just need to go to new Project > Maven > Maven OSGi Bundle like this :
The generated pom.xml begins this way:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>net.stephou.osgi</groupId>
<artifactId>HelloWorld</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>bundle</packaging>
<name>OSGiTest OSGi Bundle</name>
<dependencies>
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.osgi.core</artifactId>
<version>1.4.0</version>
</dependency>
</dependencies>
...
We notice there is only one dependency to the OSGi core and that the packaging is “bundle”. The rest of the pom is the run-on-felix profile configuration for NetBeans.
To display a HelloWorld in Apache Felix console, we need to add a HelloWorld java class. So, right-click on the source package and go to New > Other > OSGI > Bundle Activator like this :
Here is the code for the class after adding something for the console :
package net.stephou.osgi;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
/**
*
* @author Stephou
*/
public class HelloWorld implements BundleActivator {
public void start(BundleContext context) throws Exception {
System.out.println("Hello OSGi World");
}
public void stop(BundleContext context) throws Exception {
System.out.println("Goodbye OSGi World");
}
}
In the pom.xml, you can see the Bundle-Activator line has been added for the maven-bundle-plugin :
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.0.1</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-Activator>net.stephou.osgi.helloworld.HelloWorldActivator</Bundle-Activator>
</instructions>
</configuration>
</plugin>
Just Build and Run your project in NetBeans and you’ll see the following in the console :
Welcome to Felix
================
Hello OSGi World
Congratulation
To work with OSGi modules (or bundles), you’ll have to use, I let you guess …, an OSGi container. There a few open source containers including Apache Felix and Eclipse Equinox. The first one is used in application such as Glassfish v3, Service Mix 4, … and the second one in … Eclipse IDE of course.
Let’s start with downloading Apache Felix here and choose Felix Framework Distribution 3.0.3.
Unzip it and run the container (felix-framework-3.0.3/bin/felix.jar) with :
java -jar bin/felix.jar
You’ll have a g! prompt (fore felix console “gogo”) where you can enter the help command :
____________________________

Don’t be surprised next time you launch Apache Felix, installed bundles will automatically be reloaded thanks to felix-cache.
To continue …
Netbeans 6.9 integrates the OSGi interoperability. In fact, you can create OSGi bundles to use in Java applications.
It also enables you to build OSGi bundles from a Maven archetype and then access the bundles from applications that are running in an OSGi container.
- Develop OSGi bundles with Maven
- Bundled Felix container
- Use OSGi bundles in a NetBeans RCP application
Likewise, NetBeans 6.9 offers the support for JavaFX 1.3.1, Spring Framework 3.0 library, PHP Zend Framework, …
You can download the 6.9.1 version it here. And here are the feature Higlights.
Firefox 4 beta version can be downloaded here (Windows only for now). The key features are :
- HTML5 & CSS3 Support
- Privacy protection enforced
- WebM and HD videos
- WebConsole (FireBug like ?)
- Sync (settings, passwords, bookmarks, history, open tabs, …)
- Indexed DB (storing application data locally)
- Easily Switch to tab
Feel free to use the Feedback button to help Mozilla to improve Firefox.
In your apache config file (httpd.conf) add the following :
LoadModule rewrite_module modules/mod_rewrite.so
<Directory "path_to_your_drupal_dir">
AllowOverride All
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</Directory>
Test your configuration by accessing your_host/user/login (instead of ?q=user/login).
To suppress the client denied by server configuration error with ajp and Apache (I suppose you already did a a2enmod proxy_ajp), just change the Proxy setting from Deny all to Deny none in /etc/apache2/mods-enabled/proxy.conf :
<Proxy *>
AddDefaultCharset off
Order deny,allow
Deny from none
#Allow from .example.com
</Proxy>
While compiling a maven webapp using GWT on Hudson, I’ve got the following issue :
[ERROR] Exception in thread "main" java.lang.NoClassDefFoundError: com/google/gwt/dev/Compiler
[ERROR] Caused by: java.lang.ClassNotFoundException: com.google.gwt.dev.Compiler
[ERROR] at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
[ERROR] at java.security.AccessController.doPrivileged(Native Method)
[ERROR] at java.net.URLClassLoader.findClass(URLClassLoader.java:188)

[ERROR] at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
[ERROR] at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
This can be solved by telling gwt-maven-plugin to use a localWorker. Here is the config for pom.xml :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>gwt-maven-plugin</artifactId>
<version>1.3-SNAPSHOT</version>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>generateAsync</goal>
<goal>test</goal>
</goals>
</execution>
</executions>
<configuration>
<runTarget>mypage.html</runTarget>
<extraJvmArgs>-Xmx512m</extraJvmArgs>
<generateDirectory>src/main/java</generateDirectory>
<localWorkers>1</localWorkers>
</configuration>
</plugin>
Then, you will happily see :
[INFO] ------------------------------------------------------------------------

On jBPM website, we can find the features of the new release of the powerful webflow framework : jBPM 5. This one is planned for the end of 2010.
We can read that the first release will focus on the core of the various components. This refactoring of the API (setting sessions, loading process definitions, executing process instances, event listeners, …) will lead to extend the framework to more advanced features.
The key features of this release include:
- Native BPMN2 execution
- Highly configurable, embeddable, lightweight process engine using a generic process engine (PVM) underneath
- Domain-specific processes and rule / event integration
- Independent, human tasks service (using WS-HT)
- Web tooling for things like BPMN2 process creation, deployment, management, reporting (with BIRT) and human tasks
- Migration capabilities from jBPM 3 and 4 (jPDL 3, 4 to BPMN2)
More details on the jBPM 5 roadmap. This roadmap is not finalized yet, it is a proposal that might still be changed.
