To Tony:
You need to use NIO Connectors.
In your conf/server.xml file you need to replace the old Connector with NIO
Connector. Replace with this:
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" connectionTimeout="20000"
redirectPort="8443" />
Hope this helps.
