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> ...
