Tuscany - Getting Started - SCA Native Milestone release 3

Tuscany SCA Native provides a runtime implementation for the Service Component Architecture 0.96 Assembly specification and the 0.95 C++ Client & Implementation specification (found here), written in C++ and currently supports C++, Python and Ruby component implementation types. This page describes what is needed to install and run Tuscany SCA Native.
If you haven't already done so, the first step is to download the SCA Native Milestone release 3 of Apache Tuscany from our download page.

Optional: libcurl version 7.15 or higher http://curl.haxx.se/download.html
This is required for building and running the Tuscany SCA REST extension (see below). Please download and follow the installation instructions.

Installing Tuscany SCA Native

Getting Tuscany SCA Native working with the source release on Linux or Mac OS X
  1. Extract the source tar package to a folder <tuscany_sca_install_dir>
  2. The following environment variables are required:
    • TUSCANY_SDOCPP=<path to installed Tuscany SDO>
  3. See the extensions documentation for other environment variables and configration flags that are required to build specific extensions.
  4. To build only the Tuscany SCA Native kernel libraries use the following command sequence:
    • ./configure --prefix=<tuscany_sca_install_dir>/deploy --enable-static=no --enable-cpp=no --enable-wsbinding=no
    • make
    • make install
    NOTE: If you don't provide a --prefix configure option, it will by default install into /usr/local/tuscany/sca. Use ./configure --help to see all the available options: --enable-cpp build C++ component type extension [default=yes] --enable-wsbinding build Web Service binding extension [default=no] --enable-scabinding build SCA default binding extension [default=no] --enable-restbinding build REST binding extension [default=no] --enable-python build Python component type extension [default=no] --enable-ruby build Ruby component type extension [default=no] A script, build_scanative.sh, is provided that will build and install SCA Native. This script will install to the location specified by the TUSCANY_SCACPP environment variable if set or into a deploy directory at <tuscany_sca_install_dir>/deploy. This script will check the environment variable settings and will build the extensions whose dependencies are set. For example if RUBY_LIB and RUBY_HOME are set configure will be called with the --enable-ruby=yes option.
  5. Set the TUSCANY_SCACPP environment variable to point to the <tuscany_sca_install_dir>/deploy directory that contains the built Tuscany SCA distribution

Getting Tuscany SCA Native working with the binary release on Windows
  1. Unzip the supplied zip file to a folder
  2. Set the TUSCANY_SCACPP environment variable to point to the directory that was just unzipped
  3. Add the <tuscany_sca_install_dir>\bin directory to the PATH environment variable

Getting Tuscany SCA Native working with the source release on Windows
  1. Unzip the supplied source zip file
  2. The following environment variables are required:
    • TUSCANY_SDOCPP=<path to installed Tuscany SDO>
  3. You must have set up the environment for Microsoft Visual C++ tools. The build command will call vcvars32 to set the environment. Ensure the directory containing this is on your path. This will be where you installed the compiler.
  4. See the extensions documentation for other environment variables that are required to build specific extensions.
  5. Build the source:
    • cd <to where you unzipped the source>
    • build [Debug]
    This will build all the projects and put the required output into the 'deploy' directory

    Alternatively, open the VS Express workspace at <tuscany_sca_install_dir>\VSExpress\tuscany_sca\tuscany_sca.sln
  6. Set the TUSCANY_SCACPP environment variable to point to the 'deploy' directory that was just created

Tuscany SCA Extensions

Tuscany SCA is composed of two distinct areas: the kernel and extensions. The kernel provides the implementation of the Service Component Architecture Assembly Model specification, reading composite files, loading the appropriate extensions and invoking components via references and services during runtime. The extensions provide the functionality required to call a component implementation (e.g. a C++ class compiled into a dll) or invoke a binding (e.g. make a Web Services call).

The table below details the extensions that are included with Tuscany SCA Native Milestone Release 3.

Extension Details
C++ Provides the SCA C++ client API and enables C++ component implementations and interfaces. See the C++ extension documentation, the SCA C++ Client and Implementation specification for more details about the SCA C++ Programming Model and the Creating C++ SCA Components document for a step-by-step example.
Requires:
  • Java SDK 1.4 or later - for building and running the SCAGEN code generation tool, which is used when developing Tuscany SCA C++ components.
  • Apache Ant 1.6 or later - for building the SCAGEN code generation tool. This is only required when building the C++ extension from a source distribution of Tuscany SCA Native.
Python Provides a Python SCA client API and enables Python component implementations. See the Python extension documentation for more details.
Requires:
Ruby Provides a Ruby SCA client API and enables Ruby component implementations. See the Ruby extension documentation for more details.
Requires:
Axis2/C Web Services Provides the Web Service bindings enabling Tuscany to call SCA references via Web Services or expose SCA services as Web Services. See the SCA Web Service bindings specification for more details about SCA Web Service support and the Enabling Web Service access to SCA Components document for a step-by-step example.
Requires:
REST Provides the REST bindings enabling Tuscany to call SCA references via REST HTTP calls or expose SCA services as REST Services. See the REST extension documentation for more details.
Requires:
SCA Provides a default SCA binding enabling Tuscany to determine the appropriate technology to use to provide services or invoke references. Currently this defaults to using the Axis2/C Web Services binding. See the SCA extension documentation for more details.
Requires:
