This page describes the WSO2 Business Process Server architecture. The diagram below depicts the architecture with its various components.
WSO2 Business process server consist of the above diagram depicted components. Build on top of the Carbon Core like most wso2 server products, business process server embeds the apache ode runtime for BPEL execution. ODE runtime consist of BPEL compiler, Jacob, which is a framework for implementing BPEL constructs. ODE come with its own data access layer which supports in-memory execution, open jpa based persistence and hibernate based persistence. On top of the ODE runtime, we have BPEL deployer component which deploy bpel artifacts. ODE integration layer integrates the carbon/axis2 with ode runtime to expose web services and invoke partner services corresponding to BPEL services.
