ActiveVOS Designer User’s Guide
ActiveVOS provides an easy way for Java developers to use existing Java projects to build Java endpoints in a BPEL process. You can start with, or build, a package that includes an interface and a Java class that implements the interface.
Using one of the techniques that ActiveVOS provides, you can automatically generate a WSDL and schema from your Java interface. The WSDL includes the port type, operation and messages to create receives, replies, and invokes.
ActiveVOS also provides built-in features to automatically include all the necessary JARs and other files for deployment to the server.
Stateless or Stateful Invokes
Using the Java Interface, you can easily create invoke activities in BPEL. Note that the invokes can be stateless or stateful. A stateless invoke means that each time the Java code is called from the BPEL process, a new instance of the Java class is instantiated. A stateful invoke is based on a Java class that is marked implementing the java.io.Serializable marker interface. With a stateful invoke, the process uses the same Java instance throughout the lifetime of the partnerLink that uses it. Multiple invokes on the same POJO partner link result in method calls on the same POJO instance.
