This chapter describes all the steps needed to finalize the open smart grid platform development environment.
The platform uses Lombok annotations to generate extra Java methods. Without Lombok the project is not imported correctly by Maven and will not run. If you used the Vagrant installation method it should already be installed. To check if Lombok is properly installed to go Help > About Eclipse IDE and scroll down. Here you will see: Lombok <version> "<version name>" is installed. https://projectlombok.org/. If not follow this to install Lombok.
Open Eclipse by clicking the shortcut on the Desktop and import the projects.
Go to File -> Import -> Existing Maven Projects, browse to folder /home/dev/Sources/OSGP
Import the projects from location /home/dev/Sources/OSGP/open-smart-grid-platform.
In Eclipse go to Window -> Open Perspective -> Debug
In the 'Debug' perspective, go to the 'Servers' view and add a new Apache Tomcat server, Tomcat is available in the folder /home/dev/Tools/tomcat (or in another location if you didn't set up a VM using Vagrant, the latest version usually works fine).
Click on Next
Click on Finish
Make sure that Tomcat is using the correct Java Runtime Environment:
Click on 'Runtime Environment', 'Installed JREs' and click 'Add'. Choose 'next' with 'Standard VM' highlighted. Click 'Directory' and in the folder browser that is shown, use the key combination 'Ctrl + h' to show hidden files. Choose '.sdkman/candidates/java/current' and select 'Open' and 'Finish'. In the 'Installed JREs' screen, unselect the default JVM (which will be an Eclipse hotspot JVM) and select '/home/dev/.sdkman/candidates/java/current' then close the screen by clicking 'Apply and Close'. The last step is to choose the new JRE which was just added in the dropdown of the 'Runtime Environment' screen by selecting '17.0.5'. Click 'Finish' to apply.
All modules contain their own context.xml. In the module specific context.xml are the environment variables defined where the global and module specific configuration files are located. Default they will point to a location in /etc/osp/.
Continue with starting Apache ActiveMQ. If you installed an environment as described with Vagrant, you can double click the ActiveMQ shortcut on the desktop.
Alternatively you can open a terminal and run the executable manually by using the following command: (the executable can be found in the folder /home/dev/Tools/activemq/bin)
With ActiveMQ running, the Tomcat server can be started. Go to Eclipse, go to the Servers tab in the Debug view, and right click on the Tomcat server and select 'Start'.
note: In case of an error starting up for the very first time, try and start up only the module: 'osgp.core' first. This makes sure the database scripts are executed.
Open pgAdminIII and configure a connection: choose the 'Add a connection to a server.' and fill out the fields using
Host: localhost
Port: 5432
Username: osp_admin
Password: 1234
Run the script in /home/dev/Sources/OSGP/Config/sql/create-test-org.sql to insert 'test-org' organization into the organisation table of the osgp_core database.
If asked for a password, enter 1234
Go back to PgAdmin III, expand servers, select localhost -> databases -> osgp_core -> Schemas -> public -> Tables. Right click the organisation table and select to view data for the top 100 rows. Confirm that the test-org organisation has been added to the Database.
Now that everything has been set up, continue to the next chapter to start testing the Platform by sending it some requests.
After adding the server, double click on the Tomcat server in the 'Servers' view and set the following configuration: under 'Timeouts' set 'Start' to 600 and 'Stop' to 30.
Click on 'Open launch configuration', click on the 'Arguments' tab and add the following at the end of the 'VM arguments': -Xms512m -Xmx2048m -Xss512k -XX:MaxMetaspaceSize=1024m -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -Dcom.sun.management.jmxremote=true
If you want to deviate from this, you might set up the context.xml in Tomcat to be able to redirect in one file to different locations. This is optional and not required. In order to use a custom context.xml, copy the entries in /home/dev/Sources/OSGP/Config/tomcat/context.xml.sample to the Tomcat context.xml in the eclipse Servers folder, to map configuration file names to file paths.
Continue by adding the Maven Projects to the Tomcat server by right clicking on the Tomcat server and choosing 'Add and Remove'. Select all available resources, except for osgp-protocol-simulator-61850 (which is for advanced use and requires additional configuration), then click the 'Add' button. At this point, eclipse's auto-build should have built the projects, and the Tomcat server has been setup.
This starts ActiveMQ as a terminal process (this way, ActiveMQ doesn't detach from the terminal and starts running as a daemon).
This is an optional program that shows the status of the Tomcat resources in real time. To install Probe you can follow this . Note that you need to add the Tomcat users in the guide's Security part in the tomcat-users.xml in your Eclipse environment. To download the war file go to: . You need to copy the war file to: /home/dev/<your Eclipse workspace>/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/webapps.
