Create a web application in 5 minutes using Spring Boot and Maven

Create a simple web application using Maven and Spring Boot

Sometime to do an R&D, we all need a sample web application to experiment and play around. 
Below are the steps which will help to create a web application quickly using Spring Boot and Maven.
  1. Create a maven project from your IDE in this case I am using Eclipse IDE.
    • Go to File > New > Project and then select Maven > Maven Project                                 







  2. Add spring boot dependencies into the pom as shown
    • pom.xml

  3. Add Controller and View (index.html) is the shown project structure
    • Add SimpleWebController.java, Application.java and index.html as shown below             




  4. Build the project and run it
    • use the command to run it mvn spring-boot:run
    • Once the application is launch successfully within the Embedded tomcat. Browse the application using http://localhost:8080

Implementation of Documentum Business Object Framework (BOF)

BOF                                                                                                        Business Object framework is the object oriented framework provided by Documentum to build, deploy, test and execute reusable business logic component known as Business Objects.   Types of BOF Modules:   TBO – Type Based Business Object SBO – Service Based Business Object Aspects Simple Module Steps to Create different type of Modules   TBO: As TBO depends on persistence object type, we can either modify the existing functionality of the persistence object or we can add new functionality. We will discuss below how to modify the default save functionality as well we add new functionality. For writing TBO we must have a persistence object type. It is always a good practice to create a sub type of existing documentum types without trying to modify the default one. So in our case we will create an object type my_document_tbo. We can create t

Creating Session in Documentum

IDfClientX clientX = new DfClientX();   clientX is used to get the IDfClient from getLocalClient() and IDfLoginInfo from getLoginInfo   IDfClient client = clientX.getLocalClient();   IDfLoginInfo loginInfoObj = clientx.getLoginInfo();              loginInfoObj.setUser(userName);              loginInfoObj.setPassword(password);              loginInfoObj.setDomain(null); Client is used to get the newSessionManager()   IDfSessionManager sessionManager = client.newSessionManager();   sessionManager.setIdentity(docbase, loginInfoObj);   IDfSession session = sessionManager.getSession(docbase)   Below Inferfaces are used to create a documentum session if we know the username, password and DocbaseName.
