Accessing your application in GlassFish you get this error message:

org.apache.jasper.JasperException: PWC6345: There is an error in invoking javac. A full JDK (not just JRE) is required

Try to verify the parameter AS_JAVA inside of file glassfish\config\asenv.bat(.conf). This parameter should be the JDK path.

Need to access your GlassFish as administrator but in other Domain than default. Use the tool asadmin, to do that you need to specify the port of DAS to this specific Domain:

asadmin --host localhost --port 4848 enable-secure-admin
