Kim Haase commented on DERBY-2733:
----------------------------------
In addition to Dan's more substantive corrections, here are some suggestions
about language and format.
There's a run-on sentence here as well as some stray single quotation marks:
"To establish a connection using ij.dataSource, you should set the
ij.dataSource.databaseName property, otherwise ij will start with an error
indicating database '' was not found."
I'd suggest the following --
"To establish a connection using ij.dataSource, set the
ij.dataSource.databaseName property. If you do not set this property, ij will
start with an error indicating that the database was not found."
It might be clearer if the last sentence of the revised paragraph came after
the three property syntax lines, and if you changed the passive voice to
active. Also, should "databaseName" be in code font?
"If you do not specify ij.dataSource.databaseName, you can still connect to a
database after the error indicating that no database was found, but you should
not specify the protocol, just the databaseName, in the connect statement."
In example 2, you need to add a line break in the java command, similar to the
one in example 1. Otherwise the code line is too long in the output.
