Hi I came up with the following flash component to display an swf file stored in a database. It is attached above. http://www.nabble.com/file/p21408684/FlashComponent.txt FlashComponent.txt The example given below was used to code this flash component http://cwiki.apache.org/WICKET/how-to-display-a-flash-movie-from-a-byte-array.html The following class was coded by Robert Mattler which reads flash data stored in a file. public class FlashComponent extends WebMarkupContainer implements IResourceListener { int width; int height; String fileName; public FlashComponent(String id, int width, int height, String fileName) { super(id); this.width = width; this.height = height; this.fileName = fileName; } public void onResourceRequested() { getRequestCycle().setRequestTarget(new IRequestTarget() { public void respond(RequestCycle requestCycle) { try { requestCycle.getResponse().getOutputStream().write(getFlashByteArray()); } catch (IOException e) { e.printStackTrace(); } } public void detach(RequestCycle requestCycle) { // TODO Auto-generated method stub } }); } protected void onComponentTagBody(MarkupStream markupStream, ComponentTag openTag) { StringBuffer flashBuffer = new StringBuffer(); // in the following, we will append all the necessary body tags of flash // markup flashBuffer.append(""); flashBuffer.append("<embed src=\""); flashBuffer.append(urlFor(IResourceListener.INTERFACE)); flashBuffer.append("\" width=\""); flashBuffer.append(width); flashBuffer.append("\" height=\""); flashBuffer.append(height); replaceComponentTagBody(markupStream, openTag, flashBuffer); } protected byte[] getFlashByteArray() { try { File inputFile = new File(fileName); InputStream inStream = new FileInputStream(inputFile); if (inStream != null) { ByteArrayOutputStream out = new ByteArrayOutputStream(); Streams.copy(inStream, out); return out.toByteArray(); } return new byte[0]; } catch (IOException e) { throw new WicketRuntimeException("Error while reading flash data", e); } } } additional comments and suggestions regarding these components are welcome. It would also be great to have a built in wicket flash component like 'Image' which has many constructors so that users could pass the filename, width, height or even a 'Resource' as a parameter.
