Subject Cannot connect to database
Date Wed, 01 Oct 2008 06:04:24 GMT
hi!, don't know what i did wrong, help please:



A database error occurred, probably because your database connection
is misconfigured. You will have to fix this problem and then restart
or redeploy Roller before you can proceed. Here's what happened when
Roller tried to establish a connection:

    * SUCCESS: Got parameters. Using configuration type JDBC_PROPERTIES
    * -- Using JDBC driver class: com.mysql.jdbc.Driver
    * -- Using JDBC connection URL: jdbc:mysql://localhost:3306/rollerdb
    * -- Using JDBC username: scott
    * -- Using JDBC password: [hidden]
    * SUCCESS: loaded JDBC driver class [com.mysql.jdbc.Driver]
    * ERROR: unable to obtain database connection. Likely problem: bad
connection parameters or database unavailable.

Why did that happen?

In case the clues above are not enough to help you figure out what is
going wrong, here are some more details. The root cause of the problem
is an exception of type
[com.mysql.jdbc.exceptions.jdbc4.CommunicationsException]

To help you debug the problem, here is the stack trace for that exception:

    [com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
Communications link failure
