Building a simple IMAP Client that displays the subject of the messages in the “inbox” Folder using Maven (I just like Maven). Project Setup / Maven Create a new Maven project mvn archetype:create -DgroupId=com.hascode.imap -DartifactId=imap-client Edit your pom.xml and add some dependencies <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>com.hascode.imap</groupId> <artifactId>imap-client</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.1</version> </dependency> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.2</version> </dependency> </dependencies> </project> Creating the E-Mail Client Create a package .. something like com.hascode.imap.client ;) Create a simple mail client using javax.mail in a class named ImapClient package com.hascode.imap.client; import javax.mail.Folder; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Store; public class ImapClient { private Session session = null; private Store store = null; private String host = null; private String userName = null; private String password = null; public ImapClient(String host, String userName, String password){ this.host = host; this.userName = userName; this.password = password; } public boolean getMail() throws MessagingException { session = Session.getDefaultInstance(System.getProperties(),null); // session.setDebug(true); System.out.println("get store.."); store = session.getStore("imaps"); System.out.println("connect.."); store.connect(this.host, this.userName, this.password); System.out.println("get default folder .."); Folder folder = store.getDefaultFolder(); folder = folder.getFolder("inbox"); folder.open(Folder.READ_ONLY); System.out.println("reading messages.."); Message[] messages = folder.getMessages(); for(Message m:messages){ System.out.println(m.getSubject()); } return false; } } ...

With the Maven Android Plugin it is possible to build and deploy/undeploy your android app and start/stop the emulator – if you’re used to maven you won’t be going without it ;) If you’re interested in signing your apk using maven – take a look at this article Project Setup Create an android project using the android tool We need some dependencies – so create a pom.xml in the project’s root directory – I took this from the plugin samples and modified it: <?xml version="1.0" encoding="UTF-8"?> <!-- Copyright (C) 2009 Jayway AB Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

In this tutorial we are going to build a SOAP client for the popular Confluence Wiki in about five minutes. The client is going to receive rendered HTML Markup from a specified Confluence Page. Prerequisites A running Confluence Installation with SOAP API enabled – if you don’t already have one take a look at this article or if you’ve got the Atlassian Plugin SDK installed .. start a standalone instance using atlas-run-standalone .. Maven – never go without it ;) Five minutes of your life time .. ...

This short tutorial shows how to set-up a developer instance of the popular Confluence Wiki from Atlassian in a few minutes. It’s a prerequisite for a few following tutorials regarding the Confluence API and plug-in development for this system. We want a quick install so we are going to run Confluence with the embedded servlet container and HSQL database. update Meanwhile it is way much easier to use Atlassian’s Plugin SDK using atlas-mvn run or atlas-mvn-run-standalone –product confluence –version x.x.x but if you need to setup an independant instance, this article still might be useful. ...

Helo – today I wanted to post a small tutorial for a small index and search operation using the Lucene indexer and Maven for the project setup. Setup Create an empty Maven sample project using the Eclipse Maven Plugin or use the following console command: mvn archetype:create -DgroupId=com.hascode.demo.search -DartifactId=lucene-sample Here is my pom.xml there are some dependencies for Lucene defined: <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>com.hascode.demo.search</groupId> <artifactId>lucene-sample</artifactId> <version>0.0.1-SNAPSHOT</version> <name>My Lucene Search Sample</name> <description>Lucene Search Sample</description> <dependencies> <dependency> <groupId>org.apache.lucene</groupId> <artifactId>lucene-core</artifactId> <version>2.4.1</version> </dependency> <dependency> <groupId>lucene</groupId> <artifactId>lucene</artifactId> <version>1.4.3</version> </dependency> </dependencies> </project> ...

Sometimes there is a dependency not available at a remote repository and one is too lazy to set up a local maven repository – that’s when one adds a directory in the project structure and wants maven to find dependencies there. Create a directory called “lib” in the project root Add the following markup to the pom.xml inside the <repositories>-Tag (create if it does not exist): <repository> <id>lib</id> <name>lib</name> <releases> <enabled>true</enabled> <checksumPolicy>ignore</checksumPolicy> </releases> <snapshots> <enabled>false</enabled> </snapshots> <url>file://${project.basedir}/lib</url> </repository> ...
