SCA in 5 minutes

A set of specifications (15) (09/2008)• Assembly model

• how to define structure of composite applications

• Component implementation specifications• how to write business services in particular languages• Java, C++, PHP, Spring, BPEL, EJB, COBOL, C, …

• Binding specifications• how to access services• Web services, JMS, JCA, RMI-IIOP

• Policy framework• how to add infrastructure services• security, transaction, reliable messaging, …

• Integration• SCA Java EE Integration• SCA OSGi/Spring• ....

Fractal in 5 minutes

• Started by

• Open Source, fractal.ow2.org

• Early ideas back in 2000

8



• It’s a Component Model• Close to object-model (much more than EJB or

CCM)• Very general, not-domain specific• Everything is Fractal

•operative systems•middleware•services•applications

9



• Java reference implementation (Julia)• Many libraries (monitoring,communication

middlewares, deployment, transaction monitors, general purpose components)

• Many tools (F4E, Fractal ADL, Fraclet, Explorer, FScript, Juliac, FAC, Fractal BPC, BindingFactory,...)

• C reference implementation (Cecilia,Think)• Other languages (c++, .Net, SmallTalk)

FraSCAti - Runtime

•Assembly Factory: Responsible for processing SCA models

•Binding Factory: Import/Export SCA components with specified communication protocols

• Tinfi kernel: Generate SCA components glue code and create component instances

• Transaction: Manage local / distributed transactions between SCA components

Reference implementation:broader support to SCA specificationsNot very “agile”

Fork of Tuscany (same core)Federation

Focus on OSGi+JNI




FraSCAti - Performances
