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{
ErrorResponse onActivate(Object[] parameters) {
return ErrorResponse.NOT_FOUND;
}
}
------------------------------------

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;
//}
}
}
