WebLogic Training : Developing Web Services with WebLogic™

Developing Web Services with WebLogic™

WebLogic Training Overview:

Students will learn how to develop Web Services with WebLogic™ and use standards such as SOAP, WSDL and JAX-RPC. This course covers the basics of XML and includes all the features and techniques needed to program Web Services.

WebLogic Training Prerequisites :

: Familiarity with the Java language, JavaBeans, and web application architecture and concepts. Experience with WebLogic Platform helpful. Successful completion of course CTI 186, “Enterprise Java Programming Using WebLogic Platform,” satisfies these requirements.

WebLogic Training Minimum software requirements:

Microsoft Windows NT 4.0 or Windows 2000 or later. BEA WebLogic Platform 8.1. J2SE 1.4.1 SDK and J2EE 1.4 beta SDK. Java-compatible browser.

WebLogic Training Minimum hardware requirements:

Pentium at 500 mHz; minimum of 256 Mb RAM; 500 Mb free disk space; Internet connection.

Microsoft PowerPoint On instructor’s workstation for presentation purposes.

WebLogic Training Course duration:

5 Days
