In this chapter, we have looked at creating software configurations, so we can roll out Java-based applications to the BlackBerry devices in our environment and still maintain tight control over the applications by using and deploying application control policies. We also had a look at creating software configurations that enabled us to deploy device software updates to our BlackBerry devices. In the next chapter, we are going to have a look at MDS runtime applications and how these are published and distributed to BlackBerry devices within our BES environment.
