The systemd way of setting up JWS have some wrong doc

There are 2 issues with the installation steps. Both are in the section:

2.2.2.1.2. Setting up and using the JBoss Web Server with systemd

in installation guide:
https://access.redhat.com/documentation/en-us/red_hat_jboss_web_server/5.0/html/installation_guide/installing_jboss_web_server_on_red_hat_enterprise_linux

Issue 1: lack of granting folder owner.

If we strict follow this process, when starting up with systemctl jws5-tomcat.service, the command will fail and report
~
startup.sh[11437]: /opt/jws-5.0/tomcat/bin/catalina.sh: line 493: /opt/jws-5.0/tomcat/logs/catalina.out: Permission denied
~
Because the .postinstall.systemd script never do chmod at all. The later manual way introduced this step. I don't know why it got missing in the script??

Issue 2: sample JAVA_HOME is miss-leading

If we use openJDK, the default JAVA_HOME should be
~
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-11.b12.el7.x86_64/jre
~

Note the appending jre folder. If we fail to set this, JWS also fail to start. Setting them correctly in setenv.sh and user profile will solve the issue
