Ubuntu14 Tomcat7 Application deployment time

I am noticing that deploying a new applicaiton on tomcat7 takes a while to deploy. In the logs i can see all is clear but i cannot connect to http://host:8080 . Browser just hangs…

Any ideas why i cannot connect ? If i wait half an hour, perhaps i will be able to connect…

I ran into the same thing and it took forever to figure out.

Problem

The random number generator collects various bits of information from the operation of the system as an “entropy source” to provide more randomness. This process blocks the start of the Tomcat server.

Solution

Use a different source of random numbers.

In /etc/default/tomcat7, add the following line below the existing JAVA_OPTS variable.

JAVA_OPTS="${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom"
