T5: Controlling the content type in a page render request
Hi,
I'm trying to use a tml template to serve an XML file that has dynamic
content (in fact, a Java Web Start JNLP file):
<?xml version="1.0" encoding="utf-8"?>
<jnlp xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"
spec="1.5+"
...
</jnlp>
The content itself is rendered correctly, but I'm having problems
setting the correct content type for the response.
What I tried is this:
@Inject
private RequestGlobals requestGlobals;
public void onActivate(String context) {
// ... initialize internal state from context
HttpServletResponse response = requestGlobals.getHTTPServletResponse();
response.setContentType("application/x-java-jnlp-file");
}
The response still comes out as text/html.
How can I convince Tapestry that the content type should be
application/x-java-jnlp-file?

Thanks, that seems to work for me.

Thanks for the heads up, I'm now watching the tracking issue (TAPESTRY-1600).

You can use: @Meta("tapestry.response-content-type=text/xml") on your page
class.
Although XML is not fully supported by tapestry at the moment. You may run
into problems with invalid xml being generated if one of your elements
matches an HTML element such as link or img which will render the opening
tag, but will not close it. Also, I believe namespaces are stripped...

Thanks, I was only aware of the StreamResponse magic for action
requests, didn't know that it's supported for page render requests as
well.
So I could do this
StringBuilder buf = new StringBuilder();
buf.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
// ...
return new TextStreamResponse("application/x-java-jnlp-file",
buf.toString());
but I don't see a way to leverage tapestry's templating engine so the
xml becomes more maintainable.
I'll probably use the Meta annotation approach and fall back to
StreamResponse if I should hit one of the XML support problems Josh
mentioned.
Again, thanks to both of you,
Lars

hi lars,
return an instance of StreamResponse:
StreamResponse onActivate(String context) {
return new StreamResponse() {
// implement interface
public String getContentType() {
return"application/x-java-jnlp-file";
}
}
}
