3108840 - Unable to access CMC/BI Launchpad after upgrade

After an upgrade of SAP BusinessObjects, or after implementing Wily Introscope or Solution Manager, Tomcat starts but you get a 404 when going to /BOE/CMC or /BOE/BI, /biprws or /bipodata.  /AdminTools still works as does the / base page of tomcat.

Errors noted in stderr.log for tomcat:

SEVERE [main] org.apache.catalina.startup.HostConfig.deployDirectory Error deploying web application directory [<install path>\tomcat\webapps\bipodata]
SEVERE [main] org.apache.catalina.startup.HostConfig.deployDirectory Error deploying web application directory [<install path>\tomcat\webapps\biprws]
SEVERE [main] org.apache.catalina.startup.HostConfig.deployDirectory Error deploying web application directory [<install path>\tomcat\webapps\BOE]

With additional errors like the following, for each of those three web apps:

java.lang.IllegalStateException: Error starting child
