  • Generate new entity ($ seam new-entity). I named it SampleReport.
  • [OPTIONAL] Include Seam project into your IDE. Eclipse Users: Add the project

into Eclipse using File > New > Project and select General > Project (not Java Project). NetBeans Users: Open the project in NetBeans.

Get started with BIRT

  • Copy dir (include subdirs) from $BIRT_RUNTIME/WebViewerExample/WEB-INF/platform to $PROJECT/resources/WEB-INF/platform
cp -r $BIRT_RUNTIME/WebViewerExample/WEB-INF/platform $PROJECT/resources/WEB-INF/platform

Integrate

Change project defaults

  • Change ant script $PROJECT/build.xml
    • Add property 
<property name="birt.platform.dir" value="resources/WEB-INF/platform" />
    • Change war target:
<target name="war" depends="compile" description="Build the distribution .war file">
                <copy todir="${war.dir}">
                        <fileset dir="${basedir}/view" />

                        </fileset>
                </copy>

Make BIRT report

  • make $PROJECT/view/sample.xhtml report (rptdesign)

Instantiate Seam component by 

...
            <method name="open"><![CDATA[var reports = Packages.org.jboss.seam.Component.getInstance("sampleReportList", true);
            reportsIterator = reports.getResultList().listIterator();]]></method>
...

sample.xhtml all in one: Seam (BIRT) Recipe - Sample Report

    • Add create report button to $PROJECT/view/sampleReportList.xhtml
...
<div class="actionButtons">
        <s:button id="done" 
               value="Create sampleReport"

Bon appetit

  • Run ant explode, start jBoss app. server
  • Cook in oven about 40 minutes & visit restaurant :-)
