  1. Clone Git repository and import Maven project
  • Open https://github.com/SAP/cloud-espm-v2 in your web browser.
  • Click on the Copy to clipboard so that the Git repository URL of the opened GitHub repository is copied to your clipboard.

  • In Eclipse, open the Git perspective. From the Eclipse IDE main menu, choose Window > Open Perspective > Other… Select Git and choose Ok to open the Git perspective.

 

 

 

 

  • In this perspective you have the Git Repositories view on the left. As long as there is no Git Repository defined you will see 3 links (as shown here) to add a repository to the view.

  • In the corresponding menu (top-right of the view), click on the Clone a Git repository link.
  • Because you copied before the ESPM repository URL to your clipboard, the fields (URI, Host, Repository path and Protocol) of the opened dialog are filled automatically with the correct values.

  • Do not change anything, just click Next.
  • On this wizard page check that the master branch is selected and click again on Next.

  • On the last wizard page you can adjust the location of the local Git Repository, but for the scope of this tutorial we’ll just leave the default as-is.

  • Click on Finish so that the remote ESPM repository (source code) is cloned to the local location specified on the last wizard page.

 

 

  • In Eclipse, open File->Import->Existing Maven projects

  • Browse the location where you have saved the ESPM project locally from git.

 

 

  

  1. Update dependencies and build Maven project

Right click on the web project in ESPM > and choose Maven > Click on Update Project

 

  • Note! If you face errors you need to modify the parent pom.xml for certain property values depending on your environment:
    • local.server.proxy.settings – delete this if you are not behind a proxy server, else update your proxy settings here
    • browser.proxy.settings – delete this if your browser is not using a proxy, else update your browser proxy settings here
    • sap.cloud.sdk.version – The SAP Cloud Platform SDK for Java Web Tomcat 8 version that you intend to run the application with, is version 3.20.3.1
    • olingo.version – The Apache Olingo version that you intend the application to run with, the minimum version supported is 2.0.7

The application can be built with the maven command to the parent pom.xml :

clean install

Or It can be build from eclipse , Right click on the root folder of ESPM project

Then type “clean install > Apply > Ok

After building the application update the Maven Project :

Right click on the web project in ESPM > and choose Maven > Click on Update Project

 

5. Deploy the application on local Cloud Runtime

i) Run the application in HCP Java Web Tomcat 8 Server

  • Right click on the web project in ESPM > and choose the Run on Server option

  • Make sure that Manually define a new server is selected and choose SAP > Java Web Tomcat 8 Server as server type. Leave all other settings unchanged and choose Finish

 

 

  • Now a local server is started that has your espm application deployed.

ii)Create Users and Assign Role

  • To enable local users to access the Retailer UI, you need to define user IDs in the local user store and assigned the role “Retailer” to this user.

Create a user with the below information

ID      Name    Password    Role

ret     ret       123      Retailer

 

  1. Deploy the application on SAP HCP via the cockpit

Note! The application name must be “espm”, else the above URL will change based on the application name given during deployment

  1. Login to https://account.hanatrial.ondemand.com
  2. Go to JAVA application

3.Click on “Deploy Application” tab

4.  Add War File Location, Give Application Name “espm” ,select Runtime Name “Java Web Tomcat 8” and JVM Version “JRE 8”

5.After Successful Deployment , Click on Start

 

  • Configure the application role assignments from the cockpit. You basically need to add the “Retailer” role to your SAP Cloud Platform and  user to access the Retailer UI, Go to Cockpit >  Java Application > click on espm application > click on roles > Assign retailer role to user.

 

 

You can access the application from the URL

    • The eCommerce site can be accessed via the URL: https://espm<account>.hanatrial.ondemand.com/espm-cloud-web/webshop
    • The Retailer UI can be accessed via the URL: https://espm<account>.hanatrial.ondemand.com/espm-cloud-web/retailer
