REDIRECT JDBC URL WHEN USING DYNAMIC JDBC CREDENTIALS SO NOT HARDCODED

Question

I have taken over an application that uses row-level security and ADF (using
dynamic JDBC Credentials). I have been able to set the internal_connection to
a JDBCDatasource, but cannot set the Connection Type in the Oracle Business
Component Configuration to a JDBCDatasource. When I do, I receive errors that
tables are not found. When I set the value back to a JDBC URL, everything
works fine again.
I am looking for a solution where the userid and password are not hardcoded in
the BC4J.xcfg or a way to redirect this information, as we change our system
passwords every nighty days. Otherwise, I will have to redeploy the
application every nighty days.
I did not create this application, but I am sure that you could simply follow
the "How to Support Dynamic JDBC Credentials" article. From that point, you
will probably be where I am, where I have the internal_connection set to a
JDBCDataSource and working properly, but cannot set the Connection Type to
anything where the userid and password will not be hardcoded or cause failure.
I wanted to let you know that I have
found the updated How to Support Dynamic JDBC Credentials
(http://www.oracle.com/technology/products/jdev/howtos/bc4j/howto_dynamic_jdbc.h
tml) and was going to run through the "Advanced: Supporting Dynamic JDBC URLs",
but once I was done keying in
env.remove(ConnectionStrategy.DB_CONNECT_STRING_PROPERTY); I received a
depreciation message on the DB_CONNECT_STRING_PROPERTY. (Note: I am coding in
JDeveloper 10.1.3, so this may be depreciated as of then, but the ADF Libraries
for JDeveloper 10.1.3 are on our Oracle 10gAS 10.1.2 server.)
I thought maybe this would resolve my issue, but I can't be sure as the
deprecation message leads me to believe that this solution may not be viable in
the future.
UPDATE
=======
The article you are referencing is definitely an older version.
There is a newer article for 10g at:
http://www.oracle.com/technology/products/jdev/howtos/10g/dynamicjdbchowto.html
Please see if that helps.
I have already reviewed this article.
In fact, I have reviewed many versions of this document. I have not seen one
created yet for 10.1.3 though (especially without JSF as our 10.1.2 AS server
will not support it). I need to find an example or documentation that shows
how we can keep from having the JDBC URL stored in the BC4J.xcfg or a way to
use dynamic JDBC credentials with a JDBCDataSource. We do not want to store
the userid and password in the application, rather, we would like to setup
something that can be configurable from the application server.
I think we need to use the dynamic JDBC credentials because we are using the
row-level security, where we setup a database context for the user and only
allow certain records of a database table to be returned to the browser based
on that context.
Might there be a way to still use the JDBCDataSource?

Answer 1

I understand that the user provides the userid and password and that these values are setup using the Configuration class.
However, when I am to deploy the ADF Business Module with my application, I have to specify either a JDBC URL or a JDBC DataSource in the Oracle Business Component Configuration.
When I use JDBC DataSource, the code does not work properly, almost like the user's credentials are not used for the connection (I get errors like table or view does not exist).
When I use the JDBC URL, the bc4j.xcfg stores a reference in the JDBCName attribute to a ConnectionDefinition in the same file. It is in this tag of the bc4j.xcfg where the userid, sid, and password (encrypted) is stored and used when retrieving the initial context of the ADF business components.
It is these values that I want to have stored else where so that the application does not have to be redeployed in order for the password (or sid, or other connection information) to be change.
