## Package org.apache.ode.bpel.compiler Description

BPEL compiler (bpelc) classes and interfaces. Taking as input the de-referenced BPEL object model (see `org.apache.ode.bom.impl.nodes`), the BPEL compiler applies static analysis rules to ensure compliance of the BPEL model. Upon successful analysis, the compiler generates a "compiled" process description suitable for consumption by the BPEL Service Provider?s (see `com.fs.jlo.bpel.provider.BpelServiceProvider`) processing engine (also known as the virtual processing unit or VPU).

Failures in the static analysis phase are reported in the same manner as parser errors and contain detailed error descriptions and line number references to the location of the errors in the original BPEL XML process definition.
