   <resources>
     <Resource id="DefaultDataSource" type="javax.sql.DataSource">
       JdbcDriver com.mysql.jdbc.Driver
       JdbcUrl ${mysql.jdbc.url}
       UserName ${mysql.user}
       Password ${mysql.password}
     </Resource>
   </resources>

2. Modified pom.xml to support simulations build for tomcat and other servers both

     <properties>
         <mysql.jdbc.url>jdbc:mysql://mysql-5-7:3306/petstore</mysql.jdbc.url>
         <mysql.user>petstore</mysql.user>
         <mysql.password>${mysql.password}</mysql.password>
     </properties>

   Added profiles to support both builds

   <profiles>
       <profile>
         <id>tomcat</id>
         <properties>
           <mysql.jdbc.url>jdbc:mysql://mysql-tomcat:3306/default</mysql.jdbc.url>
           <mysql.user>petstore</mysql.user>
           <mysql.password>${mysql.password}</mysql.password>
         </properties>
         <build>
           <finalName>applicationPetstore-tomcat</finalName>
         </build>
       </profile>
       <profile>
         <id>websphere</id>
         <properties>
           <jta.datasource.name>DefaultDataSource</jta.datasource.name>
           <mysql.jdbc.url>jdbc:mysql://localhost:3307/default</mysql.jdbc.url>
           <mysql.user>petstore</mysql.user>
           <mysql.password>${mysql.password}</mysql.password>
         </properties>
         <build>
           <finalName>applicationPetstore-websphere</finalName>
         </build>
       </profile>
       <profile>
         <id>appz-k8s</id>
         <properties>
           <mysql.jdbc.url>jdbc:mysql://mysql-5-7:3306/petstore</mysql.jdbc.url>
           <mysql.user>petstore</mysql.user>
           <mysql.password>${mysql.password}</mysql.password>
         </properties>
         <build>
           <finalName>applicationPetstore-appz-k8s</finalName>
         </build>
       </profile>
     </profiles>

3. Generated docker/tomcat/conf/conf.d with following files:

       /PetStore/docker/tomcat/conf/catalina.policy
       /PetStore/docker/tomcat/conf/catalina.properties
       /PetStore/docker/tomcat/conf/context.xml
       /PetStore/docker/tomcat/conf/jaspic-providers.xml
       /PetStore/docker/tomcat/conf/jaspic-providers.xsd
       /PetStore/docker/tomcat/conf/logging.properties
       /PetStore/docker/tomcat/conf/server.xml
       /PetStore/docker/tomcat/conf/server.xml.original
       /PetStore/docker/tomcat/conf/system.properties
       /PetStore/docker/tomcat/conf/tomcat-users.xml
       /PetStore/docker/tomcat/conf/tomcat-users.xml.original
       /PetStore/docker/tomcat/conf/tomcat-users.xsd
       /PetStore/docker/tomcat/conf/tomee.xml
       /PetStore/docker/tomcat/conf/web.xml
   

4. Build samples:

   • mvn clean
   • mvn package — default to tomcat (custom)
   • mvn package -Ptomcat — default to tomcat (default)
   • mvn package -Pwebsphere — default to websphere

5. When using tomcat, pack war inside docker image or mount it like a volume. Deploy it somewhere using Docker or Kubernetes.

   When using WebSphere, deploy war manually on the server node.

6. Application url example: http://example.com/applicationPetstore

7. Generated appz.yml
