/bac C:\Users\Administrator\Documents\Old-WorkShop\dependencies\bac-3.0.0-b1902.war

External Dependencies

  1. Copy application configuration folders to the Tomcat default server folder as follows:

    • Copy and paste scripts folder from Murach-Forward-service under src/main/resources to C:\BluAge\Cobol2SpringBoot

    • Create new folder config inside C:\BluAge\Cobol2SpringBoot

    • Copy and paste application.yml, logback-Murach-Forward files from Murach-Forward-service under src/main/resources to config folder under C:\BluAge\Cobol2SpringBoot

Config files

  1. Replace existing DB endpoint with Aurora PostgreSQL endpoint as follows:

    • From the Package explorer, select Servers -> Tomcat v9.0 Server at localhost -> server.xml
    • Replace:
      • localhost with Aurora PostgreSQL DB endpoint captured in the chapter 3 (Create Target DB)
      • Password: VerySecret with postgres
      • Database name: murach with murach_db

  2. Start the Tomcat server from the Eclipse IDE as follows.

    • Select the server from IDE. Click right mouse button and then run below options.
      • Clean
