Service Oriented Architecture – Service Transport
HCL Leap has a powerful, and extensible, Service Oriented Architecture (SOA) integration feature. The foundation of this feature is the Service Transport.

Extending
You can extend the functionality of HCL Leap through the use of customized cascading style sheets, Javascript APIs, and REST APIs, and Service Oriented Architecture modifications.
- Using custom style sheets
  HCL Leap allows the use of custom CSS themes that can be uploaded into an application to style the user interface to meet customer needs.
- Adding services
  The following topics describe how to add services to your Leap applications.
  - Setting up your development environment
    The HCL Leap runs within an OSGi framework environment. Code that extends the Leap needs to be packaged within OSGi bundles to run. Any Java™ development environment can be used to create custom bundles, but using the Eclipse IDE built-in OSGi tooling is recommended to minimize effort and errors.
  - Providing Groups of Dynamic Services
    You can develop, deploy, and use Service Catalogs and Service Catalog Groups within the HCL Leap environment.
  - Service Oriented Architecture – Service Transport
    HCL Leap has a powerful, and extensible, Service Oriented Architecture (SOA) integration feature. The foundation of this feature is the Service Transport.
    - Creating your own custom Service Transport
      By creating a custom Service Transport, you can allow HCL Leap applications to use services from any external system, or access any data source. Alternatively, the transport can implement a custom service itself without communicating with any external system or data source.

Service Oriented Architecture – Service Transport

HCL Leap has a powerful, and extensible, Service Oriented Architecture (SOA) integration feature. The foundation of this feature is the Service Transport.

Each Service Transport represents a single communication process. Leap provides a REST transport. Additional transports can be developed and integrated into Leap to allow you to access other Services than ones expressed as REST. Each transport is written in Java™ as an OSGI bundle.
