You must use different exceptions to handle different Response Codes:
<global-results>
<result name="error503" type="header">
<param name="status">503</param>
</result>
<result name="error500" type="header">
<param name="status">500</param>
</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="com.demo.503Exception" result="error503"/>
<exception-mapping exception="com.demo.500Exception" result="error500"/>
</global-exception-mappings>
