how to display stack trace instead of 500 internal server error on weblogic

Question

I was working with tomcat 7 and when an exception is thrown the stack trace is shown in the browser. But now I'm using WebLogic 12 . Occasionally, I'll get the message "Error 500--Internal Server Error" appear in my web browser when something has gone wrong and I have to look in the log files for the stack trace of the exception. How can I get the exception to be output directly to my browser ?

FrontEnd Angular. BackEnd Java.

The solution is to configure a http filter and intercept the exception then send the message to the frontEnd. In prod mode we cant show stack trace.

in web.xml file we add this:

 <filter>
     <filter-name>msg</filter-name>
     <filter-class>com.filters.MSGFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>msg</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
