Have you already asked yourself at the beginning of a SOA or Integration project about the technology you want to use? Is it feasible to implement the integration layer completely in Java or do modern integration platforms such as Oracle Service Bus or Oracle SOA Suite provide the benefits to get closer to the often proposed IT flexibility and agility?

• SOAP has reputation for being
complex and heavyweight
• RESTful has a reputation for being
simple and lightweight
• formal contract language to
• no formal contract language to
define message formats available
define message formats
• Supports standardized security
approaches and tools
• Security is a major challenge due
to lack of standardization
• Supports XML and Binary
• Supports multiple data
types (JSON, Text,
XML, Binary)
• Preferred by todays
SOA platforms
9
• Preferred by
modern Web
and Mobile
development

10. XML vs. JSON
• XML is the “Native” format for
enterprise data exchange
• Highly formal structure
• Content CAN be validated
• Formats can change only when
all parties agree
• Supports multiple data types
(Text, Binary)
10
• JSON is the “Native” format for
modern web and mobile
applications
• No formal structure
• Content cannot be validated
• Easy to change
• Text only

11. Implementing SOAP and/or RESTFul Services in Java
• JAX-WS
• SOAP-based Web Services
• aka. „Big“ Web Services (Java EE 6 Tutorial)
• Since Java EE 5, JAX-WS (JSR 224) the preferred technology to write SOAP
web services
• defines a set of APIs and annotations that allow to build and consume web
services with Java
• JAX-RS
• RESTful Web Services
• Relies on annotations, similar to JAX-WS to specify URI mappings, HTTP
headers, content-types and resources

15. Contract-First Web Service Design
• Important for service-orientation
is the standardizing and
decoupling of the technical
contract of each service
• Service-oriented design therefore
should be based on a contract
first approach
§ avoid the use of auto-generation
tools

the master for a transfer

diverse systems in an often
ad-hoc/accidental manner

SOAP
Leads to „Spaghetti architecture“
Leads to strong coupling
Difficult to version services
Hard to maintain

31. Summary
• It‘s not really a question of Java or BPMN or BPEL or ESB
• It’s about how to combine them
• Think about integration styles
• Batch, Real-Time and/or Process
• This helps to choose the right technology
• Architecture matters!
• Separation of Concerns
• Clear Responsibilities
• Lose Coupling
• Service Categorization can help choose the right technology
• Know the strengths and weaknesses of each technology and use
appropriately
