Launching the WebViewer from code

m3t4bill

Hey, so first I'll give my version info and a brief description of what I'm trying to do:

Versions: BIRT (2.3.1), Eclipse (3.4.1), Flex (3), Tomcat (6)

Goal: To generate a report using an XML Stream as the data source, to be displayed in the WebViewer

Based on some other examples I found online, I found that to run my report with dynamic xml data, I had to write some code that set some values in the app context for my report via the following lines:

contextMap.put("org.eclipse.birt.report.data.oda.xml.inputStream", bis);
contextMap.put("org.eclipse.birt.report.data.oda.xml.closeInputStream", new Boolean(true));

I put this code in a custom servlet that I wrote, which eventually calls task.run() to display the report; everything works fine (report shows as html).

My question is, how can I make this report display in the WebViewer? I would like to take advantage of the AJAX report viewer with the export/print/etc functionality built in, but I can't seem to find how to get this working.

I found examples of people using WebViewer.display(...), but I don't have access to that from my code. Also, I CAN run reports in the WebViewer by calling into the /frameset servlet, but I can't seem to find how to do that while supplying my dynamic XML data as the source to the report!

Am I WAY off base with what I'm trying to do here? Thanks for any help you can give, let me know if you need any more information!

Bill,

Using the WebViewer.display() methods are used when deploying the viewer plugin in an RCP application. If you are doing this you can setup the appcontext like:

1 - Add a class to your application tha extends AppContextExtension

package org.eclipse.birt.examples.rcpviewer;
import java.util.Map;
import org.eclipse.birt.examples.rcpviewer.PreviewBirtAction;

import org.eclipse.birt.report.viewer.api.AppContextExtension;

public class MyAppContext extends AppContextExtension{

@Override
public Map getAppContext(Map appContext) {

Map hm = super.getAppContext(appContext);
//this has to be set on the engine not the task
//hm.put("PARENT_CLASSLOADER", PreviewBirtAction.class.getClassLoader());
String testStr= "This is a test of the appcontext";
hm.put("testAppContext", testStr);
return hm;

}

@Override
public String getName() {
// TODO Auto-generated method stub
return "MyAppContext";
}

}

Add the extension point to your plugin.xml

<extension
point="org.eclipse.birt.report.viewer.appcontext">
<appcontext
class="org.eclipse.birt.examples.rcpviewer.MyAppContext">
</appcontext>
</extension>

Finally in your code call this method before calling WebViewer.display()

ViewerPlugin.getDefault( ).getPluginPreferences( ).setValue("APPCONTEXT_EXTENSION_KEY", "MyAppContext");
