T5: 404 http error
Hi,
How can I tell T5 to send an 404 error?
Is the following code right way to show 404 error page on T5?
Because I got an error after calling "sendError()" in the code.
Test.java:
------------------------------------
public class Test{
@Inject
private Response response;
void onActivate( Object[] parameters ) throws IOException{
//if( parameters == null || parameters.length != 2 ){
response.sendError( 404, null );
return;
//}
}
}
------------------------------------
Error:
------------------------------------
[ERROR] RequestExceptionHandler Processing of request failed with uncaught
exception: STREAM
java.lang.IllegalStateException: STREAM

Re: T5: 404 http error

I am doing as follows.
------------------------------------
public class ErrorResponse {
private int _statusCode;
private String _message;
public ErrorResponse(int statusCode, String message) {
super();
_statusCode = statusCode;
_message = message;
}
public int getStatusCode() { return _statusCode; }
public String getMessage() { return _message; }
public static final ErrorResponse NOT_FOUND = new ErrorResponse
(404, null);
}
------------------------------------
------------------------------------
public class ErrorResponseResultProcessor implements
ComponentEventResultProcessor<ErrorResponse> {
public ActionResponseGenerator processComponentEvent(
final ErrorResponse errorResponse, Component component,
String methodDescripion) {
return new ActionResponseGenerator() {
public void sendClientResponse(Response response) throws
IOException {
response.sendError(errorResponse.getStatusCode(),
errorResponse.getMessage());
}
};
}
}
------------------------------------
Add contributeComponentEventResultProcessor method to AppModule.java
------------------------------------
public void contributeComponentEventResultProcessor(
MappedConfiguration<Class, ComponentEventResultProcessor>
configuration) {
configuration.add(ErrorResponse.class, new
ErrorResponseResultProcessor());
}
------------------------------------
Test.java:

public class Test{

Re: T5: 404 http error
Posted by Howard Lewis Ship <hl...@gmail.com>.
I think we need a new class, ErrorResponse, that can be returned as a
way to invoke response.sendError(). The StreamResponse handler wants
to send a stream of content, which causes problems because after
sendError() the response is committed (meaning you can't legally
obtain an output stream or print writer).
Please add an issue (and a patch :-) ).

i think its not your or a tapestry problem.
jetty gives tapestry a closed http connection
if you set a response error
i dont know, if this a special jetty behavior.
i think it should cool, if howard consider this behavior in

Re: T5: 404 http error
Posted by Sven Homburg <ho...@googlemail.com>.
i have never tested it, its only an idea:
Test.java:
------------------------------------
public class Test{
@Inject
private Response response;
StreamResponse onActivate( Object[] parameters ) throws IOException{
TextStreamResponse textStream = null;
if( parameters == null || parameters.length != 2 )
{
textStream = new TextStreamResponse("text/html", "this page doesnt
exists");
response.sendError( 404, null );
textStream.prepareResponse(response);
}
return textStream;
}
}
