Tomcat startup – Error: Could not find or load main class

When I attempt to startup Tomcat (7.0.82) on RHEL6/Java7, the logs will display this:

Error: Could not find or load main class

Notice, no specific class specified at the end of the log entry. Most hits on google seem to indicate a specific class at the end of the log entry.

In my case, I have these two servers configured identically (AFAIK). However, one server doesn't want to start. The server was installed using downloadeded binaries, custom init script, etc; using an Ansible script that worked on 3 servers in total (all same OS, Java) thus far.

Issued command: service tomcat start

Server A – Works

Using CATALINA_BASE:   /opt/tomcat/current
Using CATALINA_HOME:   /opt/tomcat/current
Using CATALINA_TMPDIR: /opt/tomcat/current/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /opt/tomcat/current/bin/bootstrap.jar:/opt/tomcat/current/bin/tomcat-juli.jar
Tomcat started.

Server B – Doesn't (Even though indicates "started")

Using CATALINA_BASE:   /opt/tomcat/current
Using CATALINA_HOME:   /opt/tomcat/current
Using CATALINA_TMPDIR: /opt/tomcat/current/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /opt/tomcat/current/bin/bootstrap.jar:/opt/tomcat/current/bin/tomcat-juli.jar
Tomcat started.
