• SeamFramework – The people who developed Seam lay down their perspective…
• Get it Working – One developer got it working, with more than a few tweaks and hacks…
• Overview from Michael Yuan – a quick list of what’s good, what won’t be supported, from a Seam expert…

Short answer, it’s not there yet, at least not with all the features and functionality you would be using Seam for in the first place…

He’s using the iui framework, which looks pretty nice. It gives you the music player/everything look and feel in a web page. See the demo for an example.

For example, this caused validation to be skipped:

When clicking on the save button, you will bypass validation and go directly to the save() method on the named component myService.

To fix this, you need to nest the tags within each tab panel:

Viola, now your required tags are properly enforced, as well as any Hibernate annotation validation that exists.

Luckily, those steps are chronicled here (by Michael Yuan) and here (by Nicolas Leroux). Oh, and Michael’s site has updated samples from his book.

Using JFreeChart with Seam can be quite useful:

package example.chartprocesser;

@Name("chartprocesser")
public class ChartProcesserBean {

    @In
    EntityManager em; // Entity Manager to access the database

    byte[] chart; // chart image (.png) as a byte array

    @Factory(value="chart")
    public void createChart() {

        DefaultCategoryDataset ds = this.getData;

        JFreeChart chart = ChartFactory.createLineChart(
                "TITLE",
                "Category Label",
                "Axis Lable",
                ds,
                PlotOrientation.HORIZONTAL,
                false,
                false,
                false
                );

        try{
     	    this.chart = ChartUtilities.encodeAsPNG(chart.createBufferedImage(400, 400));
        } catch (IOException e){
	    e.printStackTrace();
        }

    }

    private DefaultCategoryDataset getData(){
        //get the data and put into DefaultCategoryDataset
        //Then return it.
    }
}
