Process Application with java-based configured Spring container

This example shows how to configure the Spring container for the process application in Java using @Configure and @Bean. It uses the sample application from the spring getting started guide.

You have to run this example in the prepackaged distro or install the process engine as a shared engine before.

The process instance is started after deployment. See implementation of the org.springframework.beans.factory.InitializingBean in Starter

Java 7 and try-with-resource

If you start your project with the ClassPathXmlApplicationContext in Java 7, you will often code something like

try (ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("META-INF/userLibrary.xml")) {
    service = context.getBean(UserLibrary.class);
}

If you change the ClassPathApplicationContext to a AnnotationConfigWebApplicationContext, the context will not be closed on undeploy and you will get an error that the web application is unable to start again.

To resolve this, remove the try-with-resource statement and everything works fine.
