Welcome to JOpera

JOpera for Eclipse is a rapid service composition tool offering a visual language and autonomic execution platform for building distributed applications out of reusable services, which include but are not strictly limited to Web services.

JOpera helps you to deal with:

  • Bottom-up and top-down (iterative) service composition.
  • Heterogeneity: invoke SOAP and RESTful Web services, Java snippets, Human activities, Grid services, Your-Favourite services...
  • Integrated process modeling and execution.

by providing powerful tools for:

  • True visual process definition, not limited to declaring the control flow, but also providing full support for drawing the data flow.
  • Agile service composition with immediate feedback, refactoring and regression testing of your processes.
  • Efficient process execution: visual models compiled to Java bytecode.
  • Visual Monitoring, interactive steering and seamless debugging of service compositions fully integrated with the design tools.
  • Recursive service composition: automatic publishing of processes as Web services.
