"Very impressive work. This book is valuable for beginning and intermediate technologists." Dwight Mamanteo, Technical Manager, BEA Systems

"Provides explanations of Web services, tuning tips, and discussions on security that will likely be of benefit to developers as they create their Web services." Robert W. Husted, Member, Technical Staff, Requisite Software

  • Build Web services infrastructure based on service-oriented architecture (SOA)
  • Implement enterprise-class Web services using WebLogic and J2EE
  • Complete lifecycle coverage with best practices: design, prototyping, development, testing, deployment, and management
Real-world enterprise Web services implementation with J2EE and WebLogic

You've seen plenty of theory about Web services. This book is about the reality: what it takes to successfully implement J2EE Web services with BEA WebLogic in complex enterprise environments. Anjali Anagol-Subbarao, one of the world's leading Web services experts, offers powerful insights for every stage of the Web services lifecycle: design, prototyping, development, testing, deployment, and management.

Anagol-Subbarao draws on her experience architecting and building Web services infrastructure for HP's worldwide operations and takes on the challenges that face every enterprise implementer. She demonstrates how to design robust Web services that align with business processes, smoothly integrate with existing infrastructure, deliver superior performance and security, and can be managed effectively. Coverage includes

  • Primers on WebLogic Workshop, WebLogic Server, WLI, and J2EE Web services technology
  • Building effective service-oriented architectural (SOA) frameworks
  • Translating designs into working code
  • Designing for end-to-end security and tuning for high performance
  • Testing Web services and deploying them to production environments
  • Addressing the unique challenges associated with managing distributed Web services
