What this is about

As of release 1.3 Tuscany SCA is distributed via one binary distribution that includes everything. Based on user feedback, choice of a smaller distribution packages is desireable. Tuscany community is in the process of addressing this requirement. Please see mailing list for that discussion. This is not the purpose of this page.

Tuscany users have asked for a write-up that highlights module dependencies. This enables them to build their own distribution which may have a lower or higher granularity than the pre-packaged binary distributions. Purpose of this page is to help users understand how to build their own tuscany SCA light distribution based on module dependency knowledge that is shared here.

Therefore:
This page is not about building Tuscany building binary distributions to distribute
This page is about understanding dependencies so that users can build their own distribution

How to build your own distribution

Let's first understand the different categories of module types in Tuscany. This understanding will help us determine how to put the modules together to have a runnable and useful system.

  • Core type modules- These are modules that enable you to use SCA programming model to create applications
  • Binding type modules - Bindings handle protocols between two services. Tuscany supports many bindings. One or more modules constitute a binding.
  • Component type modules - These are the modules that enable you to use different languages or container models to create SCA components. Tuscany supports different component types. There are a set of modules that support each component type. For example, java, BPEL, Spring, etc. There are specific modules that support a given component type.
  • Policies type modules- There are different policy types. For example security, monitoriing, etc. There are specific modules that support each policy.
    • Databinding type modules - These modules support data types.

    Tuscany

    supports many data bindings, including Jaxb, SDO, Axiom, Json/rpc. There are specific modules that support a given data binding.
  • Runtime Type modules- Tuscany supports different runtimes. There are specific modules that support a given runtime.

    • Now that you understand the different module types, let's identify the module that fall into each category.

    Tuscany Modules Categorized

    SCA programming Model: Assembly, Deployment, Management

    *


    SCA provides a programming model for Construction, Assembly, Deployment and Management of network of services. Modules under these catetories support the SCA programming model.

    Tuscany Container
    Modules in this category are specific to running SCA in a Tuscany environment.
    Tuscany container also provides plug points for different host types, bindings, implementations, policies as well as deployment and management (contributions and domain handling).

    Policy
    Module in this category include support for enabling policies as well as policy types.

    Binding
    Modules in this category include various bindings that support different protocols. Typically Bindings are used with SCA programming model, Tuscany container and some component implementation types.

    Implementation
    Modules in this category include support for different component types. Basic SCA environment is needed to use any of these modules.

    Host Environment
    Modules in this category include support for different host environments, such as Tomcat, Jetty, etc.

    Module Category Dependency

    This section explains the dependencies amongst various categories. This information can be used to define the scope of modules needed to perform different tasks using Tuscany.

    Category

    Dependency

    SCA Programming Model

    None. It runs in any container

    Tuscany Container
