    <p>I'm trying to write an extension (plug-in) for Eclipse BIRT reporting. It involves extracting images from a file according to database entries and displaying them.</p> <p>I am using Sun's JAI-ImageIO to access TIFF file data and convert to PNG for display within the report. My code complies, but throws a NoClassDefFound runtime exception:</p> <pre><code>SEVERE: Error happened while running the report. java.lang.NoClassDefFoundError: javax/media/jai/PlanarImage at org.eclipse.birt.sample.reportitem.rotatedlabel.util.GraphicsUtil.createDocImage (GraphicsUtil.java:66) at org.eclipse.birt.sample.reportitem.rotatedlabel.RotatedLabelPresentationImpl.onRowSets (RotatedLabelPresentationImpl.java:136) at org.eclipse.birt.report.engine.extension.ReportItemPresentationBase.onRowSets (ReportItemPresentationBase.java:218) at org.eclipse.birt.report.engine.presentation.LocalizedContentVisitor. processExtendedContent(LocalizedContentVisitor.java:966) ... </code></pre> <p>I am using the PlanarImage.getAsBufferedImage() method, so it should convert to a more standard image object. I have placed the JAI jar files in my JRE and tested the same basic code outside of the Eclipse plugin environment -- that works fine. It appears to be a CLASSPATH problem, but I've verified that all JREs on my system contain the necessary jar and DLL files in the appropriate places.</p> <p>For a new JDBC driver, you must place the jar(s) in a special sub-directory of plugins -- is there a special place to put other third-party jars so BIRT can use them?</p>

    1. COThis works for an environment outside Eclipse plugin development with OSGi environment. I'm working from the standard example code of a RotatedLabel ReportItem, but modified to implement what I'm aiming for. The "suppress warnings" message I commented on yesterday was bogus -- just a classpath issue which resolved by re-ordering the imports for the Eclipse project. :-| The same error persists, however, along with a weird JDBC exception: "Cannot close the result set."

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
