If you are using maven2 for your project management you have just do two things to integrate ploinMailFactory. At first your have to add the ploinMailFactory dependency to your pom.xml:
<dependency>
<groupId>org.ploin.pmf</groupId>
<artifactId>ploinMailFactory</artifactId>
<version>1.3.1</version>
<scope>compile</scope>
</dependency>
And in step two you have to add the ploinMailFactory mirror to your ~/.m2/settings.xml
<mirror>
<id>ploinRep</id>
<name>PLOIN Repository</name>
<url>http://www.ploin-m2.de/nexus/content/groups/ploinRep/</url>
<mirrorOf>ploinRep</mirrorOf>
</mirror>
your pom.xml could look like this:
<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>org.ploin.project</groupId>
<artifactId>project</artifactId>
<packaging>war</packaging>
<version>1.0-SNAPSHOT</version>
<name>project Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.ploin.pmf</groupId>
<artifactId>ploinMailFactory</artifactId>
<version>1.3.1</version>
<scope>compile</scope>
</dependency>
</dependencies>
<build>
<finalName>project</finalName>
</build>
</project>
And your ~/.m2/settings.xml could look like this:
<?xml version="1.0"?>
<settings>
<mirrors>
<mirror>
<id>ibiblio.org</id>
<name>ibiblio Mirror of http://repo1.maven.org/maven2/</name>
<url>http://mirrors.ibiblio.org/pub/mirrors/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
<mirror>
<id>ploinRep</id>
<name>PLOIN Repository</name>
<url>http://www.ploin-m2.de/nexus/content/groups/ploinRep/</url>
<mirrorOf>ploinRep</mirrorOf>
</mirror>
</mirrors>
</settings>
