Summary

Today you spent the entire day's session covering the two remaining technologies supported by WebLogic Server: jCOM bridge software and the Extended Markup Language (XML).

You started the day by learning some simple concepts of object binding and what integration problems jCOM addresses. You looked at the different tools, such as java2com and com2java, that form part of the jCOM bridge software and how they should be used. You then studied the important steps involved in establishing communications between a Java object/component deployed in WebLogic Server and a COM component. For this purpose, you demonstrated a simple example that leveraged the Microsoft Office Word component and showed how to generate the intermediate communication classes. Apart from this, you also looked at the other side of the communication, that is, integration between a COM client and Java objects/components deployed on WebLogic Server. You covered all the elaborate steps involved in performing an early binding as well as the Zero client (no footprint on the COM client side) mode.

After this, you discussed the Extended Markup Language (XML). You started with the simple concepts of XML, such as DTDs and XML schemas, and then proceeded to learn about the SAX API and the DOM API. You then briefly read about the XML streaming AI and the Java API for XML processing.

This covers all the primary technologies that will be used by developers in WebLogic Server. In the coming days, you will be covering two new technology areas supported by the WebLogic Server: the J2EE Connector Architecure (JCA) and WebServices.
