Windows SharePoint Services v3

Key Integration Concepts

The Challenge

How to integrate existing

applications and services with Windows SharePoint Services v3.0 (WSS)

About this material

• Research:

– How does Project Server 2007

integrate and use Windows

SharePoint Services v3.0?

• Take away:

– What “best practices” can we derive from this integration effort?

Why Use WSS?

• SharePoint provides a user

friendly, consistent, customizable interface to your applications and services

• SharePoint provides rich workflow and task features

• SharePoint provides for user authentication

Areas of Focus

• Intro to Project Server 2007

• Shared Services

• Workflow integration

• Web Services API

• Content Linking and Embedding

• Administration

• Security

• Conclusions

Intro to Project Server

• Project Application Service

• Project Sites

• Project Server Interface (PSI)

Areas of Focus


• Shared Services




• Administration

• Security

• Conclusions

Shared Services

• Some services should be shared

• Services require configuration

• Each web application may require

unique services configuration

• Examples:

– Business Data Catalog

– Project Application Services

• Internal class name for the Shared

Service Provider

• Provides for services configuration

Shared Resource Provider configuration

• Shared Service Database

– BDC configuration

• Hashtable of properties

– My Site Web App

– My Site Relative Path

• Parent of SPPersistedObjects

– ProjectSites

Shared Resource Provider configuration

BDC example

• SQLSessionProvider provides

access to the correct SSP database

Project Server Example

• ProjectSite derived from

SPPersisted object

• Parent of ProjectSite set to SSP

• SPPersistedChildCollectionretrieves ProjectSites

Project Application “Shared” Service

• Windows Services wrapper

• Provisions the Queue Service and the Event Service

What to take away…

• Options for SSP Configuration:

– SPPersistedObject

– Properties Hashtable of the SRP

– SSP Database

• Consider creating your own shared services provider

Workflow Integration Requirements

• Manage external entities using

SharePoint workflow features

• Display workflow status and

history of external entities

• Use external security groups or users in Workflow scenarios

SharePoint Workflow Basics

Based on Lists or Content Types

SharePoint Workflow

Workflow History

SharePoint Workflow

• Tasks List for user interaction

Proposal Approval Workflow

• Proposal stored in MS Project

database

• Proposal Reviewers group

defined in MS Project database

• Present Workflow History, Workflow Status, and User

Interaction in SharePoint

Define a proxy list

• Proposal Proxy List

• Hidden ProposalUid field points to the Proposal

• Use custom code to populate to create the list item

Define External User Groups

Start the workflow

Start the Workflow

Build list of approvers

Workflow Execution courtesy of SharePoint

• User interaction via the tasks list

• Workflow history via the workflow history list

• Create a “proxy” list• Proxy List items reference

external objects

• Start the workflow in custom code

• Use SharePoint features for user

interaction and workflow history

• Use List event handlers to update external entities

Areas of Focus


• Shared Services




• Administration

• Security

• Conclusions

Web Services API

• Derived from SPService

• SPServiceInstance defines contributing servers

Project Server Interface (PSI)

• Exposed as set of Web Services

• Service endpoint provided by the ProjectApplicationService

• Services address is derived by round-robin algorithm across SPServiceInstances

Web Services Context

• PSIProxyBase is base for all PSI

web service proxies

• Context data is added to the

webRequest headers collection in the GetWebRequest override of PSIProxyBase

• SiteGuid, UserGuid, UserNameamong properties transmitted

What to take away…• Create an SPService

• Create one or more SPServiceInstances

• For Web Service calls use a round-robin algorithm to choose a service instance

• Call on the SPService to build the URI of the web service

• Use the headers collection of the

web request to transmit context

Areas of Focus


• Shared Services




• Administration

• Security

• Conclusions

Content Linking and Embedding

• Custom Web parts

• Application Pages

• Site Templates

Custom Web Parts

• Data access achieved via Web

Services API

• Web Services API provides for

scalable solution by selecting among one or more SPServiceInstances

• Binaries are GAC deployed

• .Webpart files deployed as part of PWA site template

Base Web Part class

• Base web part provides for web

services access

• Service end point:

– Based on the context (the site)

– Configured as a web part property

Application Pages

• Deployed to the PWA folder

beneath the Layouts folder

• References custom master page

also deployed to the PWA folder

• Includes web.config to add namespaces and controls.

• Master pages include core.css and override with custom css

PWA Site Template

• Includes .webparts

• Includes site pages

– Use default masterpage

– Include default web parts

– Customizable


• Create base web part class for

providing access to external data

• Use the SPServiceInstances for

the appropriate web service to allow for scalable web services

• Deploy web parts to the GAC

• Create your own master page and stylesheets for application pages where necessary

• Conclusions

Administration


• Liberal use of Application Pages

Areas of Focus


• Shared Services




• Administration

• Security

• Conclusions

Security

• Users in external applications

are correlated to SharePoint users

• Users are added to external groups

• User ID and User Name is

submitted in the Headers collection of web request calls

Correlating Users

Adding users to external groups


• Correlate SharePoint users with

external users when necessary

• Use external groups when

necessary

Areas of Focus


• Shared Services




• Administration

• Security

• Conclusions

Conclusions

• Consider a custom implementation of the Shared Service Provider

• Link SharePoint list items to external entities for Workflow integration

• Use the SPService to configure and manage web services

• Web parts, site pages, application pages provide a view of external data

More Conclusions…

• Use Application pages to provide

for administrative functions

• Correlate SharePoint users to

external users when necessary

• Add correlated users to external groups using SharePoint user

interface
