Subject [jira] [Commented] (CXF-4496) find of ResponseExceptionMapper do not handle runtime exceptions
Date Tue, 04 Sep 2012 10:31:07 GMT

    [ https://issues.apache.org/jira/browse/CXF-4496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447600#comment-13447600
] 

n0rad commented on CXF-4496:
----------------------------

but if the ExceptionMapper store the real class into the payload (for example SecurityException)

The client side should be able to reconstruct this Exception, and its working if you add throws
RuntimeException into the signature.

> In org.apache.cxf.jaxrs.client.ClientProxyImpl.findExceptionMapper(Method, Message)
> The responseExceptionMapper is selected based on exception defined in the resource method
signature but this method may have thrown a RuntimeException :
> {code:java} 
> @Path("/")
> public interface RestMcuBoardResource {
>     @GET
>     public RestMcuBoard getBoard();
> }
> {code} 
> does not work where this one work
> {code:java} 
> @Path("/")
> public interface RestMcuBoardResource {
>     @GET
>     public RestMcuBoard getBoard() throws runtimeException;
> }
> {code}
> a fix could be :
> {code:java} 
>     private static ResponseExceptionMapper<?> findExceptionMapper(Method m, Message
message) {
>         ProviderFactory pf = ProviderFactory.getInstance(message);
>         for (Class<?> exType : m.getExceptionTypes()) {
>             ResponseExceptionMapper<?> mapper = pf.createResponseExceptionMapper(exType);
>             if (mapper != null) {
>                 return mapper;
>             }
>         }
> +        return pf.createResponseExceptionMapper(RuntimeException.class);
> -        return null; 
>     }
> {code}
