Microsoft Office Project Server 2007: PSI Extension Web Service Generator 1.0


PSI Extensions are custom web services that execute within the Project Server Interface infrastructure, sharing the same security context as other PSI web services. PSI Extensions can be very important in building line of business and integration solutions using Microsoft Office Project Server 2007. To enable developers to take advantage of PSI Extensions, I have created a generator that not only automates the creation of web services, but also automatically deploys the web service once generated. Intended for development environments, this generator takes the drudgery out of creating, configuring, and deploying PSI Extension web services.

Overview


From the SDK: http://msdn.microsoft.com/en-us/library/bb428837.aspx

The Project Server Interface (PSI) for Microsoft Office Project Server 2007 can be extended with custom Web services. PSI extensions tightly integrate with Project Server, can call other PSI methods, and can use the same security infrastructure that the rest of the PSI uses.

Following are some scenarios that can benefit from PSI extensions:

Pulling data from the Reporting database (RDB). A PSI extension can directly query the RDB from the server. For example, third-party applications that are deployed outside a firewall cannot do a direct query of the RDB on Project Server, but can use a Web service that is a PSI extension to query the RDB.

Consolidating information from several PSI calls or manipulating and formatting data for a third-party application. A PSI extension can save bandwidth and client-side processing by doing work on the server and returning exactly what the application needs.

Performing impersonation for specific jobs more easily by running in the correct security context. For example, the existing Calendar.UpdateCalendars PSI method requires the application user to have ManageEnterpriseCalendars permission. A PSI extension could impersonate a fictitious user who has the necessary permissions. Team members could use an application to update their own calendar exceptions, without requiring a project manager to use Microsoft Office Project Professional 2007.

Integrate better with third-party and line-of-business (LOB) applications. You can extend the functionality of Project Server with PSI extensions for client applications and middleware components for LOB applications such as human resources, finance, or CRM.

Honestly, this makes devloping PSI extensions painless. Many thanks...
