Answer 1

The error in the logs says:

"RAR8054: Exception while creating an unpooled [test] connection for pool [ jjakimovski ], Class name is wrong or classpath is not set for : jdbc:mysql://localhost:3306/?user=root]]"

The screenshot in "Payara Error" shows that Datasource Classname is set to a class but the server complains it's set to an URL. Can you check that your configuration is saved and that the URL isn't specified in a field for a class? Can you check if jdbc:mysql://localhost:3306/?user=root is somewhere in the domain.xml because it shouldn't be anywhere.
