Exception Mapping Annotation seems not inhierted
Hi
It seems that the struts 2.3.4.1 Exception Mapping annotation cannot be inherited by the sub-classes. I attempted to put the annotation in the base class but the child class is unable to inherit the exception mapping. However results view can be inherited. Please advise ?
With regards
Adrian Chia

Hi Łukasz
Sorry I meant to say that result mappings defined in the base class are being "inherited" in the child class. I believe the framework actually will look for the result in the parent class if it cannot be found in itself. Anyway I updated the ExceptionMapping annotation with @Inherited so that my actions which extends this base class will inherit the exception handling.
Alternatively, I tried defining the global exceptions handling in the struts xml however it seems I cannot get it working together with annotation configurations. Information as listed below.
I defined this in the struts.xml
<package name="default" extends="struts-default">
<global-results>
<result name="exception">/ error/error.jsp</result>
<result name="runtime_exception"> /error/error.jsp</result>
<result name="error"> error/error.jsp</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="java.lang.Exception" result="exception"></exception-mapping>
<exception-mapping exception="java.lang.Error" result="error"></exception-mapping>
<exception-mapping exception="java.lang.RuntimeException" result="runtime_exception"></exception-mapping>
</global-exception-mappings>
</package>
Then I have this in the package-info
@ParentPackage(value="struts-default")
@Namespace("/dbsweb-forms/personal-loan")
package com.dbs.ploan.action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
In the Configuration Browser Plugin
The global exceptions mapping and result mapping are not listed here and when I hit the action throwing the exception I did not get to see the error page.

As far I see, it works that way from the very beginning. You can always define global-exception-mappings in struts.xml. Also what do you mean by that the "results view can be inherited" ?
@Results/@Result are defined without "@Inherited" meta-annotation so they work the same, they aren't inherited by child classes.

Hi Lukaz
You can ignore my email, as I realized that the package-info is not updated to refer to the package defined in the xml.

possible solution:
declare @Inherited for interface will allow implementor(s) to Inherit the @Inherited interface typehttp://docs.oracle.com/javase/1.5.0/docs/api/java/lang/annotation/Inherited.html
How to use @Inherited illustrated athttp://stackoverflow.com/questions/23973107/how-to-use-inherited-annotation-in-java
does this help?
