Let me answer your question one by one..

1.The <b>SAP Java Connector (SAP JCo)</b> is a toolkit that allows a Java application to communicate with any SAP System. It combines an easy to use API with unprecedented flexibility and performance. The package supports both, Java to SAP System as well as SAP System to Java calls.

<b>Webdynpro</b>: Web Dynpro is a prespective in netwever doveloper studio to dovelop webdynpro applications! go through the following URL to know more about Web Dynpros

Web Dynpro is a development environment enabling enterprises to model and develop professional applications based on browser technology, including a standards-based, device-independent complete runtime environment.

It bridges the gap between different platforms such as J2EE, ABAP and Microsoft.NET, and between different Internet browsers and mobile platforms.

It allows the developer to define screen and Workflow using Java Server Pages that call ABAP applicatons in the R/3 server. Web Dynpro can be used to provide Web services. This ability means that your Web Dynpro applications can have complete interoperability with the .NET platform.

See the link below for more information on Web Dynpro:

2.No idea bout QPZ ,i did not come across that...

3. <b>RFC ADAPTER</b> : Adapter used to connect SAP components to an Integration Server by using remote function calls (RFCs).The RFC adapter enables you to use the functions of the Integration Engine or the PCK in existing SAP landscapes. It is used by SAP systems to connect to the Integration Engine or the PCK by using the RFC interface.

The RFC adapter maps the following RFC calls to XML messages and the other way around:

Synchronous RFC calls (sRFCs) in messages with quality of service Best Effort (BE)

&#9679; Transactional RFC calls (tRFCs) in messages with quality of service Exactly Once (EO)

&#9679; The receiver RFC adapter can also process messages with quality of service Exactly Once In Order (EOIO). They are mapped to transactional RFC calls (tRFC).

Hi

JCO is basically a connector used for connecting a java system to an abap system.There are two kinds of installation one having only java and other is abap.Now if you want ur java system to talk to abap you require a jco connection to be established.

wht is the difference between JCO and webdynpro?

jCo is a piece of software developed by SAP to access ABAP systems. It includes APIs which you call from java to call RFC enabled function modules or BAPIs on the ABAP backend.

Web Dynpro is a user interface development tool. It allows developers to create applications without having to code the UI. It uses the MVC(Model, View, Controller) paridym. There are two flavors of Web Dynpro, ABAP and Java.
