Workflow

We installed Activiti Designer (the Eclipse plugin) and exported an invoice workflow and it created the following folders (and files):

├── extension
│   ├── invoice.bpmn20.xml
│   ├── invoice-context.xml
│   └── invoice-model.xml
└── web-extension
    ├── invoice-config-custom.xml
    └── invoice-share-context.xml

I copied these to our Alfresco server to the matching folders i.e:

/opt/alfresco-5.0.d/tomcat/shared/classes/alfresco/extension/
/opt/alfresco-5.0.d/tomcat/shared/classes/alfresco/web-extension/

We logged into Eclipse as an administrator, clicked on Tasks, My Tasks, Start Workflow and selected our task.
