Oracle apex ords installation

Question

I'm using Oracle 11g and Apex 18.1, Tomcat 9.0.4. During the installing of ords on step java -jar ords.war, below error is raised:

Enter the location to store configuration data: C:\ords\config
Exception in thread "main" java.lang.reflect.InvocationTargetException

I have created a setenv.h file with following statements, but no luck!

CATALINA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"
