InvalidRequestException: Process engine with name camundaProcessEngine does not exist

I have configured MSSQL database with camunda-bpm-tomcat-7.9.0-alpha2. I am trying to Register ProcessEngine through Java API using RuntimeContainerDelegate .Here it’s working fine and No Exception.
But when I tried to log in with url http://localhost:8080/camunda/app/admin/camundaProcessEngine/#/login it’s throw exception:

Here is code:

package com.camundatest;
import org.apache.log4j.Logger;
import org.camunda.bpm.application.ProcessApplication;
import org.camunda.bpm.application.impl.ServletProcessApplication;
import org.camunda.bpm.container.RuntimeContainerDelegate;
import org.camunda.bpm.engine.ProcessEngine;
import org.camunda.bpm.engine.ProcessEngineConfiguration;

@ProcessApplication
public class MultiTenantProcessApplicationEngine extends ServletProcessApplication{

      private final static Logger LOGGER = Logger.getLogger(MultiTenantProcessApplicationEngine.class);
      private void createProcessEngine(){
          LOGGER.info("\n\n**********Creating ProcessEngine *********");
          ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()
                  .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
                  .setJdbcDriver("com.microsoft.sqlserver.jdbc.SQLServerDriver")
                  .setJdbcUrl("jdbc:sqlserver://localhost:1433;databaseName=camunda2db")
                  .setJdbcUsername("camunda2")
                  .setJdbcPassword("camunda2")
                  .setJobExecutorActivate(true)
                  .setProcessEngineName("camundaProcessEngine")
                  .setHistory(ProcessEngineConfiguration.HISTORY_FULL)
                  .buildProcessEngine();

          RuntimeContainerDelegate runtimeContainerDelegate = RuntimeContainerDelegate.INSTANCE.get();

          runtimeContainerDelegate.registerProcessEngine(processEngine);
          LOGGER.info("\n\n Process Engine: "+processEngine);
      }

      public static void main(String[] args) {
          MultiTenantProcessApplicationEngine appProcessEngine = new MultiTenantProcessApplicationEngine();
          appProcessEngine.createProcessEngine();
    }
}

Any configuration need to Register Process Engine through Bootstrapping java API?

Are you sure the #createProcessEngine method is executed when you deploy the application? I only see it being called from a main method and that is certainly not invoked.
