Why does 'Cannot create PoolableConnectionFactory' happen after setting up a datasource?

After defining a Datasource and testing it with a sql query i get this:

sql-query: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure Last packet sent to the server was 0 ms ago.)

can anyone tell what i did wrong??

greetings

Yes. Your configuration is incorrect.

That error could be all sorts of things, you'll need to read the log in detail to find out what it is. It's usually (but not always) that your configuration string doesn't point at a database that the server can see, or it has no access to (the root cause will be above this line in your log for most database servers).

now im getting org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (null, message from server: "Host '172.16.1.100' is not allowed to connect to this MySQL server")

what do i have to change at the sql server??

That's more specific, excellent.

Your server security is incorrect - you need to tell it to allow access from the Confluence serer. I've not used SQL server for a long time, so you'd need to check the documentation for the correct way. (If it were MySQL, there's a "grant access to user@server" SQL statement to run, but you should do the access the way the docs for your database says are best)
