如何在Glassfish的Web服务应用程序中解决“ HTTP状态500-内部服务器错误”？

Question

I have deployed a web app including an EJB (RESTFul web service) from Netbwans 8 into Glassfish 4. This includes a cross origin resource sharing filter. I am getting the "HTTP Status 500 - Internal Server Error" error in the browser when i try to view the output of the web service (directly from the web service path, not from a client per se). I saw in a forum that i might try un-checking a Jersey option in my project properties in Netbeans but i see no such option. The only thing I've found in the logs is:

Info:   WELD-000900 2.0.0 (SP1)
Warning:   Class 'javax.ejb.PostActivate' not found, interception based on it is not enabled
Warning:   Class 'javax.ejb.PrePassivate' not found, interception based on it is not enabled
Info:   Registering the Jersey servlet application, named com.mycompany.enterprisesample.service.ApplicationConfig, at the servlet mapping /webresources/*, with the Application class of the same name.

Add

<jvm-options>-Djavax.xml.accessExternalSchema=all</jvm-options> 

line of code in the domain.xml file at glassfish4\\glassfish\\domains\\domain1\\config\\domain.xml folder

inside <java-config> </java-config> tag as :-

<java-config>
.
.
<jvm-options>-Djavax.xml.accessExternalSchema=all</jvm-options>
</java-config>

Note:- add the above line of code at the last of the –D..... code of the domain.xml file. Adding it at random position may not gurantee that this will work.
