You can use the runOrder parameter to control the test execution order for Maven surefire tests:
<build> <plugins> <plugin> ...Other options are: Option Meaning alphabetical Alphabetical reversealphabetical Reverse Alphabetical random Randomized hourly alphabetical on even hours, reverse alphabetical on odd hours failedfirst Failed first will run tests that failed on previous run first, as well as new tests for this run. balanced Balanced is only relevant with parallel=classes, and will try to optimize the run-order of the tests to make all tests complete at the same time, reducing the overall execution time. filesystem This is the default. I guess this is the order returned by the file system: uncontrolled but deterministic.

Junit does not support specifying execution order of tests until 4.11. The methods were simply invoked in the order returned by the reflection API. So, the tests are executed in a unspecified but deterministic order, i.e., you have no control over the order of execution, but if you repeat the tests, they are run in the same sequence each time. For version 4.11, you can specify the order with the FixMethodOrder annotation:
import org.junit.runners.MethodSorters; imp...From the release notes : Test execution order By design, JUnit does not specify the execution order of test method invocations. Until now, the methods were simply invoked in the order returned by the reflection API. However, using the JVM order is unwise since the Java platform does not specify...

Validation groups can be used to control which rules validation rules to run. A validation group can be identified by any Java interface (not class!). Multiple validation groups may be specified when validating. In this example, I added a validation group named MyValidationGroup ( src/main/java/com/example/MyValidationGroup.java in Maven project):
package com.example; public interface MyVal...and added a @Size rule for a person's name, because my database can only store up to 15 characters for a person's name:
package com.example; import javax.validatio...Now validate Person with a JUnit test ( src/test/java/com/example/TestPersonWithGroup.java in Maven project):
package com.example; import java.util.Set; ...Test with " mvn clean test ". The rules where groups is not specified, which belong to the javax.validation.groups.Default group, are not executed with these tests.

Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app :
<project> <modelVersion>4.0.0</modelVersion>...Create a directory named ear under javaee-app . Create pom.xml under ear :
<project> <modelVersion>4.0.0</modelVersion>...Modify pom.xml in the webapp directory so that it looks like this:
<project> <modelVersion>4.0.0</modelVersion> ...Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src...I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ):

This procedure sets up an IPSec vpn server on Linux with Preshared Key (PSK) using Openswan . Install Openswan:
# yum install openswanEdit /etc/ipsec.conf . This is about the minimum needed to run IPSec server. Instead of running L2TP on port 1701, I'm running TCP on port 8080 so that I can test the setup with nc later.

VirtualBox creates/uses a network adapter named vboxnet0 on the host, when a VM network adapter is connected as "host-only". As the VM starts, VirtualBox assigns the IP address 192.168.56.1 to vboxnet0 on the host. The VM DHCP client grabs the IP address 192.168.56.101 from the VirtualBox DHCP server. Connectivity is limited between the VM and the host - unless you configure NAT and IP forwarding on the host. For OpenWRT, if the DHCP client is not started automatically:
#/sbin/udhcpc -i br-lan -p /var/run/udhcpc.pid -s ...

A security manager is automatically installed when you run an applet, but not so when you run an application. Setting the java.security.manager property enables the default Security Manager for the application. For example, you can bind to a "privileged" port without security manager:
$ java SocketBind localhost:83 Binding to local...With security manager, it fails:
