How to integrate report designer to your web application

I was trying to import a report made in Pentaho Report Designer and I just found this interesting article -> http://www.mastertheboss.com/web-interfaces/253-develop-advanced-reports-on-jboss-with-pentaho.html

However I'm using another version from PRD, more precisely, 3.8.2-GA. And as I'm using maven in my project I tried to find all the artifacts needed.

After some time, I found these dependencies:

     <dependency>
            <groupId>pentaho-reporting-engine</groupId>
            <artifactId>pentaho-reporting-engine-classic-core</artifactId>

        <dependency>
          <groupId>pentaho-library</groupId>
          <artifactId>libxml</artifactId>
          <version>1.2.2</version>
        </dependency>
        <dependency>

          <artifactId>libswing</artifactId>

        </dependency>
        <dependency>
            <groupId>com.lowagie</groupId>
            <artifactId>itext</artifactId>
            <version>2.1.7</version>
        </dependency>        
        <dependency>
          <groupId>com.lowagie</groupId>
          <artifactId>itext-rtf</artifactId>
          <version>2.1.7</version>
        </dependency>

Thankfully, everything ran as smoothly as I imagined and my servlet succeeded using the report.
