Either way, you’re in luck! Most likely, you’re using the fatjar gradle plugin to create a single JAR for executing as “java -jar one-big-bundle.
I’m sure if you have been developing with Java and Tomcat for sometime, you are likely to run into the infamous debug error. SEVERE: Error listenerStart You will most likely start Googling it trying to find out what the heck is going on. And in trying to see the extended logging on what that “listenerStart” error means.

Here is a list of some of the projects samples that are available today: spring-samples - Revision 431: / * configuration-basic/ * jpetstore/ * mvc-ajax/ * mvc-basic/ * petcare/ * petclinic/ * petclinic-groovy/ * spring-travel/ * task-basic/ * templates/ * tutorials/ Hopefully this article will be beneficial for someone who is trying to get familiar with Spring Framework.
