The Process Server uses a Java framework that supports custom function extensions. This framework is a set of Java interfaces and classes made available for your use.

IAeFunction

and

IAeFunctionContext

are implemented to create the objects that are accessible to the engine at run-time.

AeFunctionCallException

and

AeUnresolvableException

are used to signal fault conditions. These types are resolved using the

org.activebpel.rt.bpel

package in

ae_rtbpel.jar

. Additionally,

AeUnresolvableException

extends AeException provided in

ae_rt.jar

.

You can use custom functions in any expression language.
