Here is a starter to use Open Flash Charts and Wicket:

We need a component for loading SWF objects (this is not specific to Open Flash Charts, it can be used for any swf object).
package com.mycompany.ofc2; import java.util.Collections; import java.util.Map; import java.util.HashMap; import org.apache.wicket.Component; import org.apache.wicket.behavior.AbstractBehavior; import org.apache.wicket.markup.ComponentTag; import org.apache.wicket.markup.html.IHeaderContributor; import org.apache.wicket.markup.html.IHeaderResponse; import org.apache.wicket.markup.html.resources.CompressedResourceReference; /** * */ public class SWFObject extends AbstractBehavior implements IHeaderContributor { private static final CompressedResourceReference SWFOBJECT_JS = new CompressedResourceReference(SWFObject.class, "swfobject-2.1.js"); private static final long serialVersionUID = 1L; private Map<String, String> parameters = new HashMap<String, String>(); private String version; private String flashUrl; private String width; private String height; private Component component; @Override public void bind(Component component) { this.component = component; component.setOutputMarkupId(true); } public void renderHead(IHeaderResponse response) { response.renderJavascriptReference(SWFOBJECT_JS); final String id = component.getMarkupId(); String parObj = buildDataObject(getParameters()); String attObj = buildDataObject(getVariables()); // embedSWF: function(swfUrlStr, replaceElemIdStr, widthStr, heightStr, swfVersionStr, xiSwfUrlStr, flashvarsObj, parObj, attObj) String js = String.format("swfobject.embedSWF('%s','%s', '%s', '%s', '%s', '%s', %s, %s );", flashUrl, id, width, height, version, "expressInstall.swf", parObj, attObj); response.renderJavascript(js, null); } /** * Construct. * <p/> * version can be a string in the format of 'majorVersion.minorVersion.revision'. * An example would be: "6.0.65".

/** * @see <a href="http://code.google.com/p/swfobject/">SWFObject</a> */ public class OpenFlashChart extends Panel implements IResourceListener { static final ResourceReference SWF = new ResourceReference( OpenFlashChart.class, "open-flash-chart.swf" ); final WebResource jsonResource; final SWFObject swf; final IModel<Chart> chart; public OpenFlashChart(final String id, final IModel<Chart> chart, final int width, final int height) { this( id, chart, width+"", height+"" ); } public OpenFlashChart(final String id, final IModel<Chart> chart, final String width, final String height) { super(id); this.chart = chart; final IResourceStream json = new AbstractStringResourceStream( "text/plain") { @Override public String getString() { return chart.getObject().toString(); } }; jsonResource = new WebResource() { @Override public IResourceStream getResourceStream() { return json; } }; jsonResource.setCacheable(false); String swfURL = RequestUtils.toAbsolutePath( urlFor( SWF ).toString() ); swf = new SWFObject( "chart", swfURL, "500", "300" ); add( swf ); } @Override protected void onBeforeRender() { CharSequence dataPath = RequestCycle.get().urlFor(OpenFlashChart.this, IResourceListener.INTERFACE); String data = RequestUtils.toAbsolutePath( dataPath.toString() ); swf.setFlashvar( "data-file", data ); swf.setParam( "allowScriptAccess", "sameDomain" ); super.onBeforeRender(); } /** * Actually handle the request */ public void onResourceRequested() { jsonResource.onResourceRequested(); } }
Here is the general component to show SWF data:
hymmm, for some reason when i paste the code in here, it gets an error...
