STARTING UP THE TOOL
What documentation is available?
The tool is delivered with the following documents:
- Prerequisites document. This document describes the prerequisites, including the right installation of the JDK.
- User manual. This manual describes how to use the tool.
- TestCase document. This document gives a detailed description of the testcases in the tool.
The tool does not start up and gives the error “Tool can’t be started. Please obtain a valid license and restart the tool”.
The licence.lic file that was delivered to you when buying the tool must be located in the tool directory. Please contact info@openchargealliance.org if you do not have a license file.
The tool does not start up and gives the error: Exception in thread "main" java.net.BindException: Address already in use: bind
Please make sure the tool is not running anymore. Just closing the browser does not stop the tool itself, this should be done by stopping it from the command / terminal window (or reboot the computer, just to be sure).
In case this does not help, please check the startup window, above the error. It should say:
Port 63341: true available
Port 57030: true available
Port 57031: true available
Port 57032: true available
Port 57033: true available
Port 63342: true available
If instead it says:
Port 63341: false unavailable
Port 57030: true available
Port 57031: true available
Port 57032: true available
Port 57033: true available
Port 63342: false unavailable
…please, try changing the unavailable ports to ports that are not in use. This can be done in the file port.properties.
PROBLEMS RUNNING THE TOOL
The tool start up, but it does not send any messages when starting a scenario. What is wrong?
First check the startup dialog of the tool. It should mention 6 ports, which should all say “true available”. Secondly, the tool uses the Java Development Kit, JDK. Please make sure it is installed as indicated in the Prequisites document, including setting the right PATH and JAVA_HOME definitions. This document is located in the docs folder of the tool. It does not suffice to install Java Runtime Environment (JRE).
The tool does not start up and gives the error: Exception in thread "main" java.net.BindException: Address already in use: bind
The following steps can be followed to investigate a problem:
- The first step is to look in the logging of the tool. In the tab “Detailed Report” a logfile can be downloaded with the details of the messages / logging.
- If this does not answer your question, please check “OCT.log” (in the tool folder).
If you still don’t know what the problem is, please contact support and include the detailed log and OCT.log (info@openchargealliance.org).
The start times and stop times in the tool seem to be incorrect (randomly)
Please check the timestamps the Charge Point or Central System is sending. This should be in milliseconds (3 decimals).
The JSON connection with the tool is breaking, so I cannot send messages. Why?
This can occur when using a firewall. For example, during testing we encountered an ASA firewall that discarded TCP packets that had no associated connection in the ASA connection table. The ASA looks for a SYN flag in the packet, which indicates a request to establish a new connection. If the SYN flag is not set, and there is no existing connection, the ASA discards the packet.
'Unable to connect to the CentralServer. In the OCT log an error is given indicating the Jetty server is unable to start on port 8080'
Change the port number on the configuration page to 8 and connect. You can change it back to 8080 afterwards.
