3 :: Suppose If you are PS developer then In what scenarios Component Interface will have advantages over component?

A component exposes your pages to peoplesoft only.Moreover it helps us to define common properties for a set of related pages.

5 :: Tell me Why did PeopleSoft bundle IBM WebSphere Advanced Single Server Edition rather than Advanced Edition?

The Advanced Single Server Edition (AEs) of WebSphere provides the same core J2EE and Web Services programming model as the Advanced Edition (AE) with simplified administration. In the AE version WebSphere uses DB2 or other standard database to keep the configuration and runtime information to support very large farm of WebSphere servers. However, it is one more database to install, administer and maintain. The AEs version does not use the database and uses file based configuration in a way that is similar to BEA WebLogic. PeopleSoft and IBM WebSphere architects determined that AEs version would satisfy the deployment requirements of PeopleSoft customers and would make it easy for owning and administering PeopleSoft Applications based on WebSphere.

7 :: Can you explain Why is PeopleSoft no longer supporting Apache Jserv?

Apache JServ was a servlet engine that was supported in PeopleTools 8.1x. This support has been removed from PeopleTools 8.4 for several reasons: v JServ is no longer an active product and is in maintenance mode and there are no longer any new official releases. v Our customers have exhibited a desire to use commercial products for mission-critical enterprise web application servers rather than open source solutions. Therefore, moving to support Tomcat is not seen as a reasonable solution. v Apache can still be used as an HTTP server with BEA WebLogic .

Application Messaging is used by PeopleSoft applications to communicate withone another. This is true not just for 8.1x and 8.4 applications, but also between an 8.1x and an 8.4 application. For example, the HRMS 8.3 applications, which are based on PeopleTools 8.15, can communicate with Financials 8.4applications, which are based on PeopleTools 8.4, using Application Messaging. If specific issues materialize relating to the Application Messages published by certain applications, these new messages will be made available to customers.
