I originally wrote this web application back in 2010 for a job interview. It allows the user to enter Java code and have it evaluated in real-time without compilation. BeanShell is used to evaluate Java code in a Struts2 based action.
In addition, three common solutions may be loaded into the interactive Java code window, and the capability for generating a populated int array that can be used as input for the Java code to be evaluated. This allows the user to modify the Java code in real-time and test those modifications.
To use this web application, simply drop the mcss.war file into you web application server's deployment directory ((TOMCAT_HOME/webapps for Tomcat).
I've recently updated the project to use Gradle to build and to also build a Docker image to run the webapp in. If you have Docker installed you can build the docker image by running Gradle with the dockerize task:
./gradlew dockerizeTo run the Docker image:
docker run --name 'mcss-tool' -d --rm -p 8080:8080 mcss-tool:1.0
# Note: You may need to change the port if 8080 is already in use.Once the Docker container is running you can launch the webapp at the following URL:
http://localhost:8080/mcss
