Configuring Workflow

Introduction

This section of the documentation describes the way in which the workflow system is configured for a particular installation. Properties can be configured on both the server and the designer:

Server Properties

These are defined using server workflow properties within the Server Administration Application.

• Assignment Handler: provides the class name for the implementation of the Assignment Handler. The default Xi Assignment Handler meets most requirements for assignment so this property rarely needs to be changed.

· Security Handler: provides the class name for the implementation of the SecurityHandler interface. Two workflow security handlers are shipped with the distributed Ebase Xi system:

• com.ebasetech.ufs.workflow.security.example EbaseSecurityHandler: provides minimal security checking– all users are allowed to create new workflow jobs and display a task list without any security check. In addition, if a workflow process or node does not have a security expression configured, all other actions are also allowed; when a security expression is configured, the accessing user is checked for permission to access the workflow process or node.
• com.ebasetech.ufs.workflow.security.example EbaseStrictSecurityHandler: provides a higher level of security checking - all users are allowed to create new workflow jobs without any security check, but all other actions require security authorization.

• Remote Workflow Server URL: this property allows requests for new workflow jobs to be passed to a workflow engine running on a remote server. When not specified, all requests for new workflow jobs are passed to the workflow engine on the same server. This parameter can be useful in the scenario where a server system handling user requests exists in a DMZ and a workflow server is running inside an inner firewall.

Designer Properties

These are configured using the workflow tab of designer preferences.

• Assignment Handler: this must contain the same class name as configured on the server (see above)

• Security Handler: this must contain the same class name as configured on the server (see above)

• Workflow Activity Types: provides a comma delimited list of class names of supported activities. The system includes three activity types as default, see Activity Types for more details.
