Thrown to indicate a problem with SQL Map configuration or state. Generally
if an SqlMapException is thrown, something is critically wronge and cannot
be corrected until a change to the configuration or the environment is made.
Note: Generally this wouldn't be used to indicate that an SQL execution error
occurred (that's what SQLException is for).
