Tomcat 7

Apache Tomcat (or simply Tomcat) is an open source servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Oracle Corporation, and provides a "pure Java" HTTP web server environment for Java code to run.

To get your Tomcat 7 server in the cloud, simply:

1. Log onto
Jelastic
,
2. Click Create Environment,
3. Pick Tomcat 7 for your application servers as shown in the picture below:
tomcat, use java
Once the environment is created, you can click Open in browser button next to the Tomcat server in the environment (expand the environment in the Environments pane at the top of the screen):
tomcat server
Then you can upload the Java application WAR package and deploy it to the environment.

Tomcat 7 is a little more resource intensive, but its hard not to like it. It is so easy to create complex web applications with it, pretty much negating the increased percentage in resource consumption over Tomcat 6.
