Tapestrz 5: screencast #3
Hi,
I just saw the last screecast about tapestry 5 and I would like to ask
about usign ${currentTime} construct in the page template for outputing
the properties. How it is with the escaping < > & characters (due to
XSS)? Have I any control about escaping or have I to do it on my own ...
Thanks

Re: [poll] how do people feel about me changing that validation dialog in 4.1.1 ?
Hi, for me is important to divide the part of error checking from the error presentation. Why?? For me is important to present the client and server side error the same way not to be able distinguish these 2 methods. The server side validation goes directly this way, the validation engine only finds the errors and the presentation is on the developer, with javascript this should be the same.

Re: reading a file in web root in a Tapestry fashion
Hi,
the rules are quite simple, there have to be only one service of the type ...
otherwise you have to specify what service
do you want to ...

Re: Outputing a file to user (correctly getting ahold of the getOutputStream method)
Hi,
it is not much difficult: First the URL to servise is
http://your.server/your.app.context/app?service=pdf_report&pdf=xx
where the pdf_report is the name of the service and attribute pdf specified
what report to return (you can use any
attributes you want and need).
Then you create the service:
public class PdfReportServise implements IEngineService {
protected HttpServletResponse response;
protected LinkFactory linkFactory;
public void setResponse(HttpServletResponse response) {
this.response = response;
}
public void setLinkFactory(LinkFactory linkFactory) {
this.linkFactory = linkFactory;
}
public String getName() {
return "pdf_service";
}
public void service(IRequestCycle cycle) throws IOException {
... first parse you parameters ...
... generate the report or open the file with report ...
response.setHeader(...); eg. Content-Disposition ...
response.setContentType("application/pdf");
try {
OutputStream os = response.getOutputStream();
... write your data ...
} catch (IOException e) {
throw new ApplicationRuntimeException(e);
}
}
public ILink getLink(boolean post, Object parameter) {
Map params = new HasMap();
params.put("param1", (String) ((Object[]) parameter)[0]);
... put all parameters ...
return linkFactory.constructLink(this, post, params, false); //the last
false means not to add jsessionid, true
means add if appropriate
}
}
Then you can use in template:
Get the report
and in page specification:
I hope i didn't miss anythink ...
Jirka
To add the service into application add to your hivemind.xml (If you have none
create it in META-INF directory):
