How To Resolve The Error " weblogic.management.DeploymentException: however there is no module in the application with that URI or context-root" in WebLogic 9

I was doing my environment setup for my current project. The following error was bugged my dev environment. Ofcourse it's solved finally with the solution given below.

Error Description:

<BEA-001512> <Data Source hifTxDataSource has been successfully created.>
<25-Oct-2011 12:22:37 o'clock BST> <Error> <Deployer> <BEA-149205> <Failed to initialize the application 'T***r.ear' due to error weblogic.management.DeploymentException: The application T***r.ear contains a SubDeploymentMBean with a name H******t.jar however there is no module in the application with that URI or context-root..
weblogic.management.DeploymentException: The application T***r.ear contains a SubDeploymentMBean with a name BtChaps.jar however there is no module in the application with that URI or context-root.
at weblogic.application.internal.flow.CreateModulesFlow.validateTargets(CreateModulesFlow.java:104)

Solution:
Just go to application.xml in ../META-INF folder of weblogic server.
Having context as below is illegal.
<context-root>/</context-root>
Just change it as
<context-root/> or completly remove it.
The above change definitely solve the issue.

Asynchronous Vs. Synchronous Communications

Synchronous (One thread):   1 thread -> |<---A---->||<----B---------->||<------C----->| Synchronous (multi-threaded):   thread A -> |<---A---->| \ thread B ------------> ->|<----B---------->| \ thread C ----------------------------------> ->|<------C----->|

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

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
