DataSource error during application startup

[acjacjacj]

Hi,

I'm trying to set up a testing instance of the full INATrace application. I'm sure I followed the instructions for a local enviroment, but I keep getting a Spring error when trying to start the back-end. It says something about the datasource not being determinable. It is however set in the "application.properties" file, with the same values as the readme guide.

This is my readable error:
ina-trace_1 | ***************************
ina-trace_1 | APPLICATION FAILED TO START
ina-trace_1 | ***************************
ina-trace_1 |
ina-trace_1 | Description:
ina-trace_1 |
ina-trace_1 | Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
ina-trace_1 |
ina-trace_1 | Reason: Failed to determine a suitable driver class
ina-trace_1 |
ina-trace_1 |
ina-trace_1 | Action:
ina-trace_1 |
ina-trace_1 | Consider the following:
ina-trace_1 | If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
ina-trace_1 | If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

This is my logged error stack trace:

Hi,
It looks like you have not configured the datasource URL. Depending on which database you use, you have to specify the JDBC DataSource connection URL. For example, if you will use PostgreSQL, the connections string would be: jdbc:postgresql://host:port/database (You have to specify the host and port, on which the database is located, and the database name). Prior to that you have to install and configure the database and create the tables.

Hi MBJuric,

Thanks for your response. I was using my own Mysql 8 container and hadn't created the neccessary database yet. My colleague has the back-end working now so it's resolved!
