This chapter has given an overview of component technology. It discussed standards for interoperability, including (D)COM, CORBA and Java. It gave an example application using both Java and CORBA, and discussed the issues involved in extending an existing library with CORBA.

Objects versus components

1


slide: Section 6.1: Objects versus components
 In section 1, we looked at some definitions of components to clarify how component technology differs from object technology. A brief overview of existing technology was given and an attempt was made to demystify component-based development.

Standards for interoperability

2


slide: Section 6.2: Standards for interoperability
 In section 2 we looked in somewhat more detail at component technologies that, each in their own way, set a standard for interoperability.

The Java platform

3


  • a matter of perspectives
slide: Section 6.3: The Java platform
 In section 3, we discussed the Java platform from a variety of perspectives, as listed in slide 6-3. We weighted the pros and cons of Java from each of these perspectives, and concluded that Java is a promising platform.

An Internet-based workgroup application

4


  • agent, workgroup, agenda, appointment
  • CORBA server, Java applets
slide: Section 6.4: An Internet-based workgroup application
 In section 4, we looked at the outline of a simple workgroup application, that allows for creating appointments mediated by agents that act as a representative of a user. The workgroup illustrates the use of Java applets and CORBA servers.

Crush -- extending hush with CORBA

5


  • factories -- (distributed) object tables
  • server wrappers -- remote objects
  • client-side adaptors -- transparent typing
slide: Section 6.5: Crush -- extending hush with CORBA
 Finally, in section 5, we discussed the issues involved in extending a framework such as hush with CORBA. Apart from the definition of interfaces and server wrappers, we defined client-side adaptors to attain a transparent integration of CORBA object handles and the types native to the framework.
