如何在jQuery的ajaxError中获取自定义异常消息

Question

I know we can get exception using xhr.responseText , but in my APP, the responseText display as exception description amended by Tomcat. please refer to below image, is there anyone can tell me how can I control the content of responseText or how to handle custom message(may be in a better way). I need a title and content in the response as I can display them in dialog of Jquery UI. BTW, I throw a general exception just like throw new Exception("some error happens");

You can define custom error message in your web.xml like this -

<error-page>
    <error-code>404</error-code>
    <location>/error.jsp</location>
</error-page>
<error-page>
    <error-code>500</error-code>
    <location>/Error.jsp</location>
</error-page>

You can have any text in your error.jsp page, that text will be sent to client on respective error
