When there is exception in the backing bean, a blank page is displayed. I was expecting response with status code 500. When I debug the http response the status code is 200. I have configured the webapp to display error page on status code 500. Since it is not returning status code 500, this page is not displayed. In web.xml 500 /500.jsf I am using Sun RI Implementation of JSF on weblogic 10.3 Please some one help me. Here's a stack trace. Note :I purposely introduced devide by zero exception in my backing bean action. java.lang.ArithmeticException: / by zero at com.pamer.inetol.sam.webapp.hcp.beans.PatientManagerBean.action_cancelPatientRe   More>>
