Glassfish Server enable as a windows service to start in Automatic way

due to some company requirement I have enable the asadmin> create-service and set the GlassFish Server as a windows service while setting it to Start in a Automatic way. I am using Netbean 8.0.
However after I enable the Glassfish server service in auto method and when I try to deploy a Try sample project (Java Web) in Netbeans, after I RUN the project I got the following error in the Internet explorer.
HTTP Status 500 - Internal Server Error
Exception report
Internal Server Error
The server encountered an internal error that prevented it from fulfilling this request.
org.apache.jasper.JasperException: PWC6345: There is an error in invoking javac. A full JDK (not just JRE) is required
The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 4.0 logs.
However when I remove the Glassfish server from windows service list and when I run the project back, then it successful.
since I have no idea on java and all, can kindly help me to find the root cause of this or what is the workaround?
Thanks

Seems like you had problems with Java versions of what Tomcat is using(points to JAVA_HOME) at environmental variable and JDK of Weblogic. Also it would be good if you send some logs and exception messages.
