The Contrast Java agent analyzes the behavior of Java applications running on J2EE containers; newer frameworks like Netty, Play or Vert.X; FatJar/microservice applications like SpringBoot; or even regular desktop Java applications. If there's a JVM, the Java agent can get security insights.
To start analyzing an application, install the Java agent by adding it as
-javaagent JVM parameter. After installation, continue to use the application as you normally would. (If it's a web application, just click on links, submit forms using normal data, and so forth.) The Java agent's sensors gather information about the application's security, architecture and libraries. You can see the results of the agent's analysis in the Contrast UI.
To install the Java agent, complete the following steps:
Note: You must not rename the agent file. If the agent file name is changed, the agent will fail to connect with the Contrast application.
java -javaagent:contrast.jar -jar <app-name>.jar
To see examples for specific technologies, go to Installation by Container and select the article for the container you want to use.
To start analyzing an application, use the web application as you normally would in your browser: click on links, submit forms using normal data, etc. The sensors of the Contrast Java agent will gather information about the application’s security, architecture and libraries. You can view the results of the agent’s analysis in the Contrast UI.
If you want to download the agent and test with WebGoat, Contrast has a public repository to help you get started.
Contrast is tested and proven to be compatible with the following technologies; however, Contrast is also compatible with many more that aren't listed.

Contrast tests WebSphere on Windows and Linux, and offers limited support for zSeries and AIX environments. Customers using WebSphere on SPARC Solaris require version 18.104.22.168.
Proguard includes Java bytecode optimization features which break basic assumptions that runtime agents like Contrast rely on. Proguard users that want to protect their applications with Contrast need to avoid these optimizations by using Proguard's -dontoptimize configuration option.
