Introduction

You can use WSO2 Carbon Studio to create your CApp. A CApp is deployed in the form of a Carbon Archive (.car) file. Following are some of the advantages of using CApp

  • A simple way to deploy artifacts
  • CApp is a collection of sub-artifacts packed together into a single deployment artifact, a .car file. With the .car file it's very easy to deploy multiple artifacts in to GReg rather than deploying & maintaining them separately. For example, CApp supports

      • Registry Resource Artifacts
      • Registry Handlers Artifacts
      • Registry Filter Artifacts
      • Registry Aspect Artifacts
      • Governance Archive (gar Artifacts).
    • Using CApp you can name, version or even specify where a particular artifact should get deployed, rather than someone else having to figure it out
    • Idea of hot deployment/update/undeployment is built-in for CApp ( however OSGi related artifacts in a CApp has some limitation when it comes to hot update/undeployment)
  • Our development platform - Carbon Studio, supports creating, testing, debugging & deploying CApp artifacts intuitively with the least effort.
