title: NoClassDefFoundError for Birt Class EngineException
body: <p>Has anyone <strong>added the Birt Library to a project's build path</strong> successfully?</p>
  
  <p>I installed Birt in Eclipse using Help-->Install New Software and copy paste the link for Birt 4.2.2 from the official website. Birt was downloaded from the internet and a new perspective appeared, namely Report Design. Apart from it no Library, no nothing. So I designed my report and started writing Java code in order to do a PDF export of my report, as I found on the internet. I wrote the following:</p>
  
  <pre><code>// Export Birt report
          String format = HTMLRenderOption.OUTPUT_FORMAT_PDF;
          EngineConfig config = new EngineConfig( );
          config.setEngineHome( "C:\\Tools\\Eclipse\\plugins\\org.eclipse.birt.report.viewer_4.2.2.v201302041142\\birt" );
          HTMLEmitterConfig hc = new HTMLEmitterConfig( );
          HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler( );
          hc.setImageHandler( imageHandler );
          config.setEmitterConfiguration( HTMLRenderOption.OUTPUT_FORMAT_HTML, hc );
          ReportEngine engine = new ReportEngine( config );
          IReportRunnable report = null;
          String reportFilepath = "C:/Workspace/reports/new_report.rptdesign";
          try {
              report = engine.openReportDesign( reportFilepath );
          }
          catch ( EngineException e ) {
              System.err.println( "Report " + reportFilepath + " not found!\n" );
              engine.destroy( );
              return;
          }
          IRunAndRenderTask task = engine.createRunAndRenderTask( report );
          HTMLRenderOption options = new HTMLRenderOption( );
          options.setOutputFormat( format );
          options.setOutputFileName( "C:/Workspace/reports/output.pdf" );
          task.setRenderOption( options );
          task.setParameterValues( parametersMap );
          try {
              task.run( );
          }
          catch ( EngineException e1 ) {
              System.err.println( "Report " + reportFilepath + " run failed.\n" );
              System.err.println( e1.toString( ) );
          }
          engine.destroy( );
          return;
  </code></pre>
  
  <p>Of course no Birt Library is set in my Build Path, so all Birt objects were red. I manually added all Birt jars that existed in Eclipse's plugins folder and all the reds disappeared. It seemed that everything was going great. When I run it I get:</p>
  
  <pre><code>java.lang.NoClassDefFoundError: org/eclipse/birt/report/engine/api/EngineException
  </code></pre>
  
  <p>while the org.eclipse.birt.report.engine.api package exists in my Build Path
  and the EngineException.class exist in the package. I am feeling that there are jar files that I am missing.
  I have searched for a solution in Birt home page and found nothing. Most tutorials have instructions regarding how to build a report. But nothing regarding how to get the library up and running with Java.</p>
  
  <p><strong>Is there a standard or automatic or official way to add Birt Library to Eclipse?</strong> It is made by Eclipse. It shouldn't be so difficult. Any help will be appreciated.</p>
