RE: [udig-devel] Re: DB2 and Oracle support
|
Dear All,
Since uDig seems to become a very promissing piece of Open source GIS
Software we are very willing to test some of its features.
We were attempting to have a look at uDig with a direct connection to
the "unfriendly" database Oracle. Unfortunately we miss any
documentation on how to install the Oracle plugin(s) and where the
Oracle stuff can be found. In other Emails I saw some discussions about
it, so, can someone of you please help us out?
Regards,
Victor
WeNix, Unix!

Sorry it was not clear. In a sense I am "still" planning as I am trying
to figure out update sites and how I am supposed to solve this problem.
I was going to try it out on Oracle and then ask you what you thought.

Fair enough, lets just say that workflow is a bit difficult for the open
source development model (witness the inclusion of a mock oracle-jdbc
driver with uDig so people can checkout and compile even when they do
not have the product).

Correct - that is the design and it will work.

True - and here is how I hope to do that. For Oracle and DB2 (where we
cannot include the jdbc driver) I need to find a way to let users point
me towards the jdbc driver they already have.
I can think of two ways to do this:
1. Through a Preference page - When the user points towards a new jdbc
driver, I would need to figure out how modify the classpath of the
already running plugin.
2. When the users goes to install the feature (if you download a nightly
build you can see a "Find and Install..." menu item in the help menu.
My impression is that option number 2 is what I am supposed to do. There
is also a manual process - ask the user to place the jdbc driver jar
into the correct plugin.
