All Implemented Interfaces:

org.copperengine.core.common.WorkflowRepository, org.copperengine.management.FileBasedWorkflowRepositoryMXBean, org.copperengine.management.WorkflowRepositoryMXBean

public class ClasspathWorkflowRepository
extends org.copperengine.core.wfrepo.AbstractWorkflowRepository
implements org.copperengine.core.common.WorkflowRepository, org.copperengine.management.FileBasedWorkflowRepositoryMXBean

Easy to use implementation of the WorkflowRepository interface. This workflow repository looks for its workflows in the normal classpath, just one or more package names of those packages containing the workflow classes need to be configured.

Compared to the FileBasedWorkflowRepository this is quite easy to use, because workflows do not need to reside in a dedicated source folder, they don't need to be deployed as java source files and no java compiler (JDK) is needed to run the application.

On the other hand there is no hot deployment feature and the JMX interface does not show the java source code of the deployed workflows. Anyhow, this workflow repo is probably suitable for most simple COPPER applications.

See ClasspathWorkflowRepositoryTest.java testExec() for sample usage.

 {
     final ClasspathWorkflowRepository wfRepo = new ClasspathWorkflowRepository("org.copperengine.ext.wfrepo.classpath.testworkflows");
     final TransientEngineFactory factory = new TransientEngineFactory() {
         protected WorkflowRepository createWorkflowRepository() {
             return wfRepo;
         }
 
         protected File getWorkflowSourceDirectory() {
             return null;
         }
     };
     TransientScottyEngine engine = factory.create();
     engine.run("org.copperengine.ext.wfrepo.classpath.testworkflows.TestWorkflowThree", "foo");
 }
