WebSphere Message Broker


What is an ESB?
An Enterprise Service Bus (ESB) is a flexible connectivity infrastructure for integrating applications and services. An ESB can power your Services Oriented Architecture (SOA) deployment by reducing the number, size, and complexity of interfaces between your applications and services.
ESB does the following:
  • Matches and routes communications between services
  • Converts between different transport protocols
  • Transforms message formats between requestor and service
  • Identifies and distributes business events from disparate sources
What are ESB products?
  • WebSphere ESB is a platform-based ESB and optimized with WebSphere Application server for an integrated SOA platform.
  • WebSphere Message Broker is a platform-independent based ESB and is built for universal connectivity and transformation in heterogeneous IT environments.
  • WebSphere DataPower Integration Appliance XI50 is an purpose-built hardware ESB and is built for simplified deployment and hardened security.
Why do i need both MQ and Message Broker?
WebSphere Message Broker and WebSphere MQ address different business needs.
  • WebSphere MQ provides secure and reliable connectivity between application and systems, supported on more than 80 platform configurations. This provides the ability to move data unchanged between virtually all business environments likely to be deployed in a business infrastructure.
  • WebSphere Message Broker is used as a transport for moving data between applications, but it is capable of performing additional tasks through understanding of data formats, allowing it to provide intelligent routing and transformation of XML data formats.

Advantages & Disadvantages of Synchronous / Asynchronous Communications?

  Asynchronous Communication Advantages: Requests need not be targeted to specific server. Service need not be available when request is made. No blocking, so resources could be freed.  Could use connectionless protocol Disadvantages: Response times are unpredictable. Error handling usually more complex.  Usually requires connection-oriented protocol.  Harder to design apps Synchronous Communication Advantages: Easy to program Outcome is known immediately  Error recovery easier (usually)  Better real-time response (usually) Disadvantages: Service must be up and ready. Requestor blocks, held resources are “tied up”.  Usually requires connection-oriented protocol

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag

XML Binding with JAXB 2.0 - Tutorial

Java Architecture for XML Binding (JAXB) is an API/framework that binds XML schema to Java representations. Java objects may then subsequently be used to marshal or unmarshal XML documents. Marshalling an XML document means creating an XML document from Java objects. Unmarshalling means creating creating a Java representation of an XML document (or, in effect, the reverse of marshaling). You retrieve the element and attribute values of the XML document from the Java representation. The JAXB 2.0 specification is implemented in JWSDP 2.0. JAXB 2.0 has some new features, which facilitate the marshalling and unmarshalling of an XML document. JAXB 2.0 also allows you to map a Java object to an XML document or an XML Schema. Some of the new features in JAXB 2.0 include: Smaller runtime libraries are required for JAXB 2.0, which require lesser runtime memory. Significantly, fewer Java classes are generated from a schema, compared to JAXB 1.0. For each top-level complexType, 2.0 generates a v
