what you&aposre doing is trying to use a @Insert component to insert a blobin your page. It will never work like that since Tapestry will actually tryto display the string representation of your blob (if you callpersonImage.toString() you&aposll get exactly that "oracle.sql.BLOB@1176e8a").You need something a bit more sophisticated. I&aposve done exactly what you&aposretrying to do so I&aposll explain it to you. I won&apost past all my code since it&apossvery application-specific.First you need to create a service that will produce the image contents, socreate a class for that. Something like this:public class ImageService implements IEngineService { public ILink getLink(boolean isPost, Object parameters) { Object personId = parameterArray[0]; Map serviceParameters = new HashMap(); serviceParameters.put(ServiceConstants.SERVICE, getName()); serviceParameters.put(ServiceConstants.PARAMETER, new Object[] {personId }); return linkFactory.constructLink(this, isPost, serviceParameters,true); } public String getName() { return "personImage"; } public void service(IRequestCycle cycle) throws IOException { // here you have to set the appropriate content type // I&aposm assuming it&aposs a jpeg image. ContentType contentType = new ContentType("image/jpeg"); OutputStream outputStream = webResponse.getOutputStream(contentType); Object[] parameters = linkFactory.extractListenerParameters(cycle); Integer personId = (Integer) parameters[0]; // you have the ID, so here you do whatever you have to do // to fetch the person object Person person = whatever... // then you have to write the image contents to the output stream. int length = person.personImage.length(); outputStream.write(person.personImage.getBytes(0,length)); outputStream.close(); }}On the html page you&aposll have to use an img tag with the source being theservice you just created:On the component&aposs java class you&aposll need something like:// This is the hivemind service being injected@InjectObject("service:ImageService")public abstract IEngineService getProductImageService();public String getImageLink() { Object[] parameters = new Object[1]; // I&aposm assuming there is a "person" variable in page // with the person object you want to display. parameters[0] = person.personID; return getProductImageService().getLink(false,parameters).getAbsoluteURL(); }... next you&aposll also have to tell hivemind about the service in yourhivemodule.xml<service-point id="ImageService" interface="org.apache.tapestry.engine.IEngineService"> <invoke-factory> <construct class="my.package.ImageService"> <set-object property="linkFactory" value="infrastructure:linkFactory"> </construct> </invoke-factory></service-point> <contribution configuration-id="tapestry.services.FactoryServices"> <service name="personImage" object="service:ImageService"></contribution>That&aposs more or less how I did it. I think that&aposs about it, but if I forgotanything I guess the docs can fill in.Denis
