Re: Custom error result for ExceptionMappingInterceptor
Another option would be to extend the ExceptionMappingInterceptor and override the findResultFromExceptions method. In the overriden method you can do your checks and return a global result accordingly Antonios On 20 October 2012 21:35, JOSE L MARTINEZ-AVIAL jlm...@gmail.com wrote: Hi, I want to use ExceptionMappingInterceptor to manage any exception thrown while processing a request. The issue I have is that I want to map the action to diferent results depending on some parameters of the request. More specifically, the browser's client can send three diferent types of request to my app: FullScreen - It's a full navigation, i.e., the browser goes to a diferent URL. In this case all the screen is reloaded, obviously. PaneScreen - Part of the screen is updated using HTML code ( the result of a JSP). The request is done using AJAX, so there is no navigation in the formal sense. AJAX/JSON - The page retrieves some information from the server in JSON format using AJAX. There is also no navigation. The problem I have is that depending on the type of navigation (And I can know that looking at the headers and the namespace of the action request) I need to send diferent error results to the client. If it's a FullScreen request I need to send a full error page. If it's a PaneScreen request, then only a handful of HTML needs to be sent, since it only affects the pane that send the request. Last, but not least, if it is a AJAX/JSON screen I want to send a 500 error code with specific information in JSON format so a meaningful message can be shown to the user. After researching a bit, it seems my only options are to chain an HandleExceptionAction to the ExceptionMappingInterceptor result, so the action can send the correct result to the user ( http://stackoverflow.com/questions/5746941/mapping-struts-2-exception-handler-to-an-action ), or implement my own version of ExceptionMappingInterceptor. Is there any other option I am missing? thanks K:
Re: json result type not parse OGNL expressions in params
I just reviewed the code, and it seems that the HttpHeaderResult only
parses the parameters headers and errorMessage, but not the parameters
status or error. I think it could be a nice thing to have. my workaround is
to extend JSONResult incorporating the following:
public void setStatusCode(String statusCode) {
ValueStack stack = ActionContext.getContext().getValueStack();
setStatusCode(Integer.parseInt(TextParseUtil.translateVariables(statusCode,
stack)));
}
public void setErrorCode(String errorCode) {
ValueStack stack = ActionContext.getContext().getValueStack();
setErrorCode(Integer.parseInt(TextParseUtil.translateVariables(errorCode,
stack)));
}
It works fine but I think that this feature should be incorporated to all
parameters. I would like to know opinions from other people before opening
a jira issue for this.

Hi,
I'm using a json result type defined as follows:
result-type name=json-action class=org.apache.struts2.json.JSONResult
param name=ignoreHierarchyfalse/param
param
name=includePropertiesresultName,resultMessage,data.*,fieldErrors.*,actionErrors.*,actionMessages.*/param
param name=excludeNullPropertiestrue/param
param name=noCachetrue/param
param name=errorCode${errorCode}/param
/result-type
Everything works great, except the parameter errorCode. I populated the
errorCode in the ValueStack doing:
invocation.getStack().set(errorCode, errorCode);
where errorCode is an int. But the errorcode is not been setup in the
response, and in fact I can see the following stacktrace:

I just tried that, but it does not make any difference.
