People are still discovering the benefits of the free tool from VMware SpringSource, called Spring Insight Developer. This post provides an explanation of what Spring Insight Developer does, how to set it up with Apache Tomcat, and an example of available plugins. For a better visual, there is also a video of the new Spring Insight 1.8.3 GUI embedded below.
Spring Insight is an extremely useful, time-saving, free tool for Spring developers and also has plugins for Grails, GemFire, Hadoop, Hibernate, JMS, JNDI, LDAP, MongoDB, RabbitMQ, Redis, Spring Batch, Spring Integration, Tomcat, and many more on Github. In the latest release of Spring Insight, VMware introduced a new "split-agent" architecture that will enable this tool to be extended to more runtime languages besides Java, such as .NET, Ruby, PHP, Python, etc. There is also a bounty program where you can get paid to develop new plugin or offer to pay others.
In a nutshell, Spring Insight Developer lets you see what your code is doing. When, as a developer, you press a button in your application’s GUI, you can see what Java code is invoked, how it translates into SQL, and quite a bit more. Before we show it in action, it’s worth mentioning a few of the benefits.
Let’s take a look at a simple example of tracing your app, viewing the details, and seeing the code in action.
Traditional Java EE (JEE) app servers bring complexity to the mix. In addition, they are costly and consume a lot of resources. Forrester wrote an article in 2011 about the costs saying, “Use Apache Tomcat. It is free.” IDC’s research from 2011 points how enterprises are moving “toward lower-cost application platforms that shift them closer to private, public, and hybrid cloud offerings.” Of course, you can find plenty of historical posts and debates from practitioners on costs and resources from past years.
So, if you are looking at middleware support for mobile apps, in-memory databases, auto- scaling, and virtual/cloud infrastructure, then you might want to check out our webinar coming up on Thursday, October 25th. In this session, we will cover quite a bit about vFabric tc Server:
For development and operations teams, a presentation that covers how to manage applications properly from cycling updates to determining failures.
Your business applications provide all the components that do the real work for your enterprise and use Tomcat as the engine to power that work. How can you ensure that your applications on Tomcat are managed properly? How do you cycle application updates over a group of more than twenty server instances? How do you determine the failure of application whether it is during start-up, execution or application shutdown?
For development and operations teams, a presentation that covers how companies can migrate to Tomcat and manage large scale deployments and enterprise environments.
Are you considering migrating off more expensive and heavyweight application servers?
Do you need additional enterprise class server capabilities that Tomcat can’t provide?
