Re: is there a way to get the hostname:port and IP address
The Tapestry-related answer is that Tapestry provides an injectable
service, Request [1], that is a shadow of the current thread's
HTTPServletRequest [2]:
import org.apache.tapestry5.services.Request;
@Inject
Request request;
public String getRemoteHost() {
return request.getRemoteHost();
}
public int getLocalPort() {
return request.getLocalPort();
}
but since Request only has a subset of the properties that
HTTPServletRequest offers, for many purposes you'll need to directly
access HTTPServletRequest directly, which you can also inject:
import javax.servlet.http.HttpServletRequest;
@Inject
private HttpServletRequest httpServletRequest;
public String getRemoteAddr() {
return httpServletRequest.getRemoteAddr();
}
Be sure the servlet API is on your classpath. If using Maven, for example:
!-- Provided by the servlet container, but sometimes referenced in
the application code. --
dependency
groupIdjavax.servlet/groupId
artifactIdservlet-api/artifactId
version2.5/version
scopeprovided/scope
/dependency
Also note that if you have a separate web server (e.g. Apache HTTP)
in front of your app server, it may or may not be configured to pass
the correct client information to the app.

Re: Streaming a binary file - IllegalArgumentException
Hi As Bob Harner said, the img tag you are using is a normal html tag that takes a url. If you look at the example you are linking to, you will see that it is using 2 different classes (UploadStore and SomePage) These pages have different tasks. UpploadStore redenders a image based on the ID in the activation contextwhile SomePage is the page beeing displayed. You should therefore create a page (without the tml file) that returns the binary content when it is activated (you may test this by pointing your browser to it. ) and then link to it from your index page.

Re: Streaming a binary file - IllegalArgumentException
Hi Sigbjørn, Hi Bob,
Yeah, I think, I get the idea.
So, if you want to use the HTML img tag for streaming, you need a
org.apache.tapestry5.Link (for example, it can be created by a
componentResources.createEventLink(image, id)) or you need to inject
a LinkSource (just as in the UploadStore example), and use the
createPageRenderLink method, because you cannot stream the
BufferedImage object directly.
Thank you both very much for your help. You have solved my first
Tapestry problem in my life. :)
It is not impossible, that someone might be interested in the
solution, so I paste my code here. It uses my Hello1.jpg, Hello2.jpg,
Hello3.jpg and Hello4.jpg, depending on the address.id and pastes them
into a Grid component.
Index.tml:
t:grid source=addresses row=address include=city, image
p:cityCell
div id=CellItem_1
t:pagelink page=about
context=address.id${address.firstName}/t:pagelink
/div
/p:cityCell
p:imageCell
img src=${getImageLink(address.id)} alt=the image
should be here /
/p:imageCell
/t:grid
-
Index.java:
-
public Link getImageLink(int id) {
return this.componentResources.createEventLink(image, id);
}
StreamResponse onImage(final int i) {
return new StreamResponse() {
public String getContentType() {return image/jpeg;}
public InputStream getStream() throws IOException {
File fnew=new File(d:\\Hello + i + .jpg);
BufferedImage originalImage=ImageIO.read(fnew);
ByteArrayOutputStream baos=new ByteArrayOutputStream();
ImageIO.write(originalImage, jpg, baos );
return new ByteArrayInputStream(baos.toByteArray());
}
public void prepareResponse(final Response response) {}
};
}
Now, I will try to read my JPG Images from my Hibernate/MySql database
and place them into the above mentioned Grid component.
Have a nice day!
Bela

Re: TapestryIoC: Is it possible to receive an OrderedConfiguration's ID?
Nothing specific that I know of... ...you could iterate over the ServiceActivities in the ServiceActivityScoreboard service looking for a matching service interface and take the ID from there. It's not nice, but as long as you know the type of the service, it should work. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
