Hello!
I'm running Tomcat 7.0.11 on Windows Server 2008 Enterprise, and recently
installed Windows Updates (to the tune of like 80 of them) on the server.
After doing so, when attempting to view the list of web apps running in Tomcat,
I get the following:
org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [HTMLManager] in context with path
[/manager] threw exception

Nothing else Tomcat-wise has changed on the server.
Anybody else out there running Tomcat in this type of environment and run into
this issue (basically a fully-patched Windows 2008 server)? The trouble was
manifest when our monitoring tools stopped working for Tomcat. :(
Thanks in advance for the help!
Tom
