(ii) Operation Details :- It contain a name of the operation, what is input, what is output and fault. (iii) Transport Protocol Details:- It contain a HTTP and SOAP details. (iv) Address Details:- It contain a End point URI and URL. Definition is the root element of WSDL. Wsdl contains multiple blocks Type block, Message block, Port Type block.

 1. What is Java Callout ? Ans:- Through which we can execute some java methods. 2. What is assign ? Ans:- it is a action to initialize a variable. 3. What is replace ? Ans:- which will replace the element specified by the Xpath in In variable with expression. which can replace node content and entire node. 4. What is insert ? Ans:- through which we can add one more element in xml message. 5.  What is delete ? Ans:- through which we can delete an element. 6. What is publish ? Ans:- through which we can invoke one way services. 7. What is configuration file ? Ans:- Configuration file contains the endpoint url's of the business services, which is used in migration of services from one server to other server. => we can create a configuration file through sbconsole for a project. => we can execute a configuration file through sbconsole. 8. What is Routing table ? Ans:- through which we can achive content based routing. 9. What are your roles and responsibilities in OS...

1. What is Proxy Service in OSB ? Ans:- It is one of the component of OSB and used to connect to source system. 2. What is Business Service in OSB ? Ans:- It is one of the component of OSB and used to connect to target system, you can define business service using Wsdls(Web Service Description language) just as you would define a proxy service. However, the configuration of business service is differs from that of proxy services in that business service doesn't have a pipeline. therefore, a business service not implemented by the OSB pipelines.   3. What is Route node ? Ans:- Route node is like container, we can place some routing actions. also called as request boundary   so that we cannot place any more actions after the route node. it is used to route the message from proxy service to business service. 4. What is Routing Action ? Ans:- By using routing action we can invoke a business service, input for a routing action is request body, Output is response body. 5. Wha...

By using deployment we can deploy our service to the server and test the service is it working  as aspected or not. How we can deploy the service to server. Solution:-     We have multiple projects in Jdeveloper, I want to deploy HelloWorld to the server. Right-click on the Helloworld project--->Deploy--->HelloWorld Note:-  If you are deploying first time then you need to configure the port nos, username and password             as mentioned below:- Click on Next then Choose the server  Click on Next then Finish Now you go to the bottom side, you have deployment tab here you check the deployment is successful or not. Its shows deployment finish means deployment done successfully, Now we go to the Server and test the service In-Browser open  https://localhost:7101/em Give the credentials username and password. After login we find like this page Click on Target navigation (Rounded by red mark) Open SOA folder the clic...

Business service is used to connect with the external system, its is used to connect with the target system. Scenario :- Create an OSB service in which you call another service(for Ex Hello world service). Solution:- Create an OSB project  double click on  In the proxy service layer, right-click on the layer then Choose Insert Transport---> Choose HTTP Click on next choose the wsdl , click on Create a Wsdl Here you need to create a wsdl from previous HelloWorld xsd and choose Interface type as Synchronous Interface, now select input payload and output payload like that only you need to choose output payload Click on next then finish, a window appears like Right-click one external services layer than Insert Protocal--->HTTP--->Click one next  Rename business service you can select messaging service or Wsdl  in request and response payload select from previous Helloworld.xsd as you selected previously. Business service is created like    wire up with...

Operational Branch :- It is used to route the incoming requests to different business service based on the operation name. If no any conditions satisfied then by default branch is executed. Scenario:-  Create a OSB service which will accept two numbers, and it will perform addition and subtraction according to the operation. Solution:-  Create a project name it as ConditionalBR (as per your choice you can give it)  create a schema as per the requirement and name it as per your choice      Right-click on project name--->New--->Xsd Schema (give the schema name as per your choice) <xsd:element name="Request">     <xsd:complexType>       <xsd:sequence>         <xsd:element name="Num1" type="xsd:integer"/>         <xsd:element name="Num2" type="xsd:integer"/>       </xsd:sequence>     </xsd:complexType>   </xsd:element...
