Web Services with PeopleTools : Whenare they the right option

Web Services are only one of many integration options

When are Web Services good options?

!ultiple consumers of a single interface

"f consumer is e#ternal and needs to be Authenticated

Consuming partner integrations

"ntegrating with Standards Based Tools

$ S%A technology

$ &evelopment Tools

$ Business "ntelligence

S%AP or *est?

Component "nterface or AppClass?

*owset or non+rowset message?Parts and containers or &ocument?



Provide Web Service :-sing a Component "nterface




Synchronous Service %peration for eachComponent "nterface methods

Automatically creates .onrowset+based !essages

with Schemas based on the C" de/nition

Builds handler de/nition that points the C"

Any to ,ocal routing is de/ned

.aming convention for Web Service is C"01name2

Supports user de/ned methods

Step 3: Provide Web Service Wi5ard

$ Publish as Web Service by selecting theabove generated Service de/nition




,imitations

$ This is the easiest way to provide a Web Service but itcomes at a cost

$ The interaction between the Web Service andComponent "nterface is 6enerated and Can .ot be!odi/ed

State !anagement can be a problem

There is no support for level deletes

$ Consider using an AppClass that manipulates theComponent "nterface as an alternative



Provide Web Service :9uery Access Service

Peoplesoft has delivered Service and Serviceoperation to e#ecute a uery from an e#ternalsource

!ultiple delivered service operations to e#ecuteueries and retrieve results

9ueries can be e#ecuted realtime or throughbatch

*esults can be obtained realtime ;<!,P7 8T!,etc=> or through /le ;(#cel etc=>
