jQuery, SOAP, Ajax and updated UI for workflow
(Apr 03, 2009 05:14)
New UI, with jquery actions
To enable the toolbar in the tempo task list, edit the tempo-ui-fw.xml in the config folder and set the following:
<property name=”useToolbarIcons” value=”true”/>
This will tell the UI to load the optional icons as seen in the screenshot below:
Delete: delete the tasks from the task list, and also completely from the database. This [...]

Tempo Tasks List Performance, Load Testing and some Ruby scripting
(Mar 12, 2009 12:41)
A customer reported some performance degradation with the task list under a bit of load, (~500 active tasks per user), so decided to have a quick look and boost off a bit the different components involved in sorting, displaying and all the jazz that the Tempo task list is doing.
So, a few quick ruby scripts [...]

Embedded LDAP in 2 minutes (… and a bit of RBAC)

Embedded LDAP in 2 minutes
Running a standalone LDAP server is rather easy.
Getting that server to be embedded in your server may be slightly different.
ApacheDS has quite a few links to do it properly, but you need to do some gymnastics to compile the war file, set it up, start the server and finally get it [...]

Apache Sling, Jackrabbit, JCR, Webdav and Tempo
(Jan 24, 2009 00:06)
Sling could be one of the coolest java project in the content management area nowadays. It is completely based on Jackrabbit, and also includes Apache Felix for OSGi components registration.
It is very customizable, and has the great advantage of being ready to put in production, and or to be used as a base for further [...]

Intalio
Tempo is a set of runtime components that support human workflow within an service-oriented architecture (SOA). Our main goal is to provide a complete and extensible workflow solution with a bias towards interoperable technologies (BPEL, BPEL4People, XForms, REST, and web services) as a default implementation.

| Web-based User Interface for Tempo |
The User Interface as a portlet(here embedded in liferay) |
The task manager process, responsible for handling task in tempo. This is running as a process. |
BPEL4People is a specification authored by BEA, IBM, Oracle, SAP and other companies that defines BPEL extensions for human workflow functionality. Tempo follows this architecture to provide all the workflow functions defined in BPEL4People. At this time, Tempo does not rely on any BPEL extensions and uses fully interoperable WSDL and REST interfaces as its core APIs. Over time, we intend to implement the full BPEL4People specification.
The BPEL4People specification can be found here.
The WS-BPEL specification can be found here
Tempo offers the following features:
- Extensible task object model
- Task List web-based user interface for users to manage their tasks (accept, complete, cancel, reassign, etc.)
- Security framework for role-based access control (RBAC) and single sign-on (SSO)
- Customizable set of BPEL processes to define workflow behavior (task assignment, escalation, etc.)
- Deployment Service to deploy task definitions, forms, etc.
- Attachments support
- Web-service and REST-based interfaces that allow integration with practically any language and web/user interface technology.
Technology integrations:
- Native XForms integration based on the Orbeon XForms engine.
- LDAP Directory integration for user authentication and role-based authorization
- Task data persistence in relational database (via JDBC)
- Storage of attachments in relational database (via JDBC)
- Task list user-interface implemented with Spring MVC and JSP/JSTL
Note that Tempo only provides runtime components; we recommend using design tools such as Intalio's Designer or the Eclipse BPEL Designer to develop your processes and forms.
Tempo is designed for software developers and architects familiar with Java, XML, BPEL, REST, web services and, to a lesser extent, XForms.
