JClient Dynamic JDBC Creadentials

Hi!
I need to implement solution described in article "How To Support Dynamic JDBC Credentials" in JClient application. As I understand, the only thing I need is to create my own class MyEnvInfoProvider and use it in JClient code.
When I run application in local configuration, it works perfectly. But when I tried deploy it to Standalone OC4J - exception appears: Error while opening JDBC connection and SQL Exception invalid arguments in call.
It seems that class MyEnvInfoProvider is not being using.
Any ideas? Thanks.

Dynamic JDBC credential insert ERORR

Hi,
I have ADF-JCLient application where I implemented dynamic JDBC credentials. BUT There is a PROBLEM :
I created a conection to the database ( in "Connections" Tab) for the schema user1.
And I'm using the connection for my ApplicationModule.
When I enter in the application as "user2" I can't insert in the views with the error :
"JBO-26041: Failed to post data to database during "Insert": SQL Statement "INSERT INTO Table1(ID,USER_ID,PCTL_ID) VALUES (:1,:2,:3)"
As you see because I'm "user2" I need to prefix the table name in the insert statement with "user1.Table1"
in order for the insert statement to work.
SO What is needed is to add the schema name in all statements send to database. This should be done at the view Level with a parameter "Schema_name".

You can add the schema name in the EO dialog to the tablename. Just change MY_TABLE to MY_SCHEMA.MY_TABLE.
But i am not sure if this propagates into your VO XML files.
Otherwise you can create public synonyms in the database for all tables in your schema, but i would not recommend this because you can run into conflicts with oter applications running in your database.

Questions about example "Dynamic JDBC Credentials for Model 1 and Model 2"

Hello,
i am trying to set up dynamic JDBC authentication in my ADF BC application - i want that it'll work like in Forms - a dababase user with the proper priveleges can log into my ADF BC application using his database login and password, and work with application.
I've read the paper "How To Support Dynamic JDBC Credentials" at
http://www.oracle.com/technology/products/jdev/howtos/10g/dynamicjdbchowto.html
and test the very useful example, created by Steve Muench, which i've got from
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#14
The example works, but when i'm transfer its realisation in my application - it doesnt work the right way. The problems is the following:
1. I can connect and work successfully only under the owner of the schema - the username and password of which i've wrote in the "jbo.server.internal_connection" string of the AM configuration.
2. When i'm connecting under other users, which have all the rights to work with the db objects, used by application, i got the main page with the "Access Denied" message - as i have no priveleges to the tables.
3. The big surprise is that if i am entering the fake username and password - the random letter combination - then i am getting the same behavior as in p.2 - the main page with the "Access Denied" message!
And the last question is:
4. Is it possible to set up the dynamic jdbc authentication using the build-in JDeveloper functions - i mean not to use that additional code, not override the ADF Binding Filter, and so on, but set up the similar behaviour (users log in using their db names and passwords) in several minutes following the standart documentation?
Thanks in advance!

One more question:
I have 2 independent Application Modules in my application - to make the 2 transactions independent one form another, when working with different parts of project - and while using dinamic JDBC authentification, the user connects only in the first AM under the username he's entered, but the 2nd AM works under the predefined earlier (during development) connection for that AM.
How can i make the 2nd AM to be connected under the logging in user (same as the 1rst AM)?

Dynamic JDBC URls at Runtime

Hi Experts,
I did my application in jdev 11.1.1.6 and deployed using Jdbc Url connections and it worked successfully (Actually I m working with 2 diff Database connectiosn in my application)
But the thing is my company need me to do something like I should be able to dynamically use Jdbc url connections at runtime so that they want to have QA db and PROD db inside the application
and dynamically change them itseems. (i.e I will have 4 Db in which 2 for QA and 2 for PROD)
Is there a way where I can achieve them. If so help me out.
Thanks,
933601

Hi,
You could store the database URLs in a properties file in the app server filesystem, then look them up in the dynamic JDBC code before setting the session attributes. So your QA app server has a properties file containing the URLs for the 2 QA databases and the PROD app server has a properties file containing the URLs for the 2 PROD databases.
If you want a single app server to talk to multiple sets of databases you could pass a parameter to the login screen. Based on this you decide which database(s) to connect to.

Dynamic JDBC Credentials and using ADF Region ERROR

Hi,
I used solution by Steve Muench, Dynamic JDBC Credentials (for ADF Faces Rich Client)
(129. 11g Dynamic JDBC Credentials for Model 1, Struts, Trinidad, and ADF Faces Rich Client 11.1.1.0.0 06-AUG-2008), but it works not correct in case of using ADF Dynamic Region (or simply ADF Region).
I have added in ViewControllerJSFRichFaces a page (main.jspx) including ADF Dynamic Region consisting of 2 simple tasks flows. Action of the Login button, if login and password are correct, redirect to main.jspx
There are to cases.
1) Login and password are correct:
In this case all work fine.
2) Login and password are not correct:
It does not work. redirect to login.jspx does not occur as it is expected, but the following page (main.jspx) is loaded, herewith thrown exception: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.
I would be very grateful you for help.

Hi,
hard to say from your description if this is a bug or an implementation problem. Note that errors that occur in regions are not handled by the exception handler of the the parent page and require special handling within the region. In other words, if the problem is in the region then it needs to be handled in here. I think the right strategy here is to not show the region until a valid connection exist. Is the login performed from the parent page ?

REDIRECT JDBC URL WHEN USING DYNAMIC JDBC CREDENTIALS SO NOT HARDCODED

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?

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.

ADF 11g: Dynamic JDBC Credentials, how to postback paramters

I am currently trying out dynamic jdbc example from Steve. An additional implementation I am trying to accomplish is to retain the username in the input field upon a failed login without having it displayed on the url (the example passes parameters back by putting it on the url followed by redirect). Typically this can be done by setting a new request attribute and using a forward instead of redirect, but the example has some interesting code which explicitly avoids a request forward (See below).
    private void forwardToLoginPage(ServletRequest request, ServletResponse response) throws ServletException,
                                                                                             IOException {
        HttpServletResponse responseHttp = (HttpServletResponse)response;
        responseHttp.sendRedirect(loginPageRedirectName());
...Can anyone shed some light on why this is?

Steve Muenchs "Dynamic JDBC" on WLS 11g (10.3.1)?

Hi,
I try to run Steves Example "11g Dynamic JDBC Credentials for Model 1, Struts, Trinidad, and ADF Faces Rich Client" on Standalone WLS 11g (10.3.1) but it doesn't works... on integrated WLS it runs without problems. The WLS-Log shows:
Modul: oracle.adf.mbean.share.config.ADFConfigLifeCycleCallBack
Message: Failed to create config mbean.
details: java.lang.Exception: oracle.mds.core.MetadataNotFoundException: MDS-00013: No Metadate for Metaobject "/META-INF/adf-config.xml" found.
Does somebody have the example to run brought? Or if new settings are necessary for the example on WLS 11g?
Kind regards
Martin

Hi,
since Steve's solution has nothing to do with the adf-config, I suggest you create a simple testcase that reproduces the problem. It appears as if the ADF binding is not set up properly

Using Dynamic JDBC Credentials with jazn security (web.xml) in BC

I have followed the document “How To Support Dynamic JDBC Credentials” http://www.oracle.com/technology/products/jdev/howtos/10g/dynamicjdbchowto.html to connect to the database using Business Components, as the user who logs in the application. (Proxy)
The only matter is that as I could see, I cannot use the application server integrated security (with roles) to protect the web resources.
The main objective is to protect the web resources using Declarative J2EE authentication and authorization using the Data Base users (and roles). I have implemented the solution for the first part (authentication) using DBLoginModule (DBSystemLoginModule) from Frank Nimphius and Duncan Mills, it’s working OK, but I need the second part; how to use the user that is logged in as the PROXY user of the BC connection.
Using the DBLoginModule, and the “How To Support Dynamic JDBC Credentials” separates works fine, but I can’t make them work together.

Frank, Thanks a lot for your quick answer.
"Maybe you should look at using database proxy users with ADF BC so you can use the J2EE authenticated user principal as the database schema to connect through. I am working on documenting this approach, which however needs some more time of writing and testing."
Yes, that's exactly what I need!!!
Can you give me some tips about how to do that.. Do you have any idea of when you will finish that document?.
By the way, I'm using FORM authentication, but I don't know how to modify what’s in the “How To Support Dynamic JDBC Credentials” document, to use the J2EE authenticated user principal as the database schema to connect through.
One of the problems is that when using this approach, I cannot get the J2EE security to redirect to the login page...
Any help would be really appreciated

Dynamic JDBC credentials example application from Steve Muench

Apologies for this newbie question...but I'm trying to understand the Dynamic JDBC credentials example application from Steve Muench:
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#14
I think I understand most of it but the one bit I dont understand is why it customizes the ADF Page Lifecycle (DynamicJDBCADFPhaseListener, DynamicJDBCPageLifecycle, DynamicJDBCPageLifecycleContext).
Can anyone explain to an ex-forms developer why this code is there?
I'm also trying to work out a way for the session to be invalidated when the user logins again
e.g. a user logins, he doesnt use the logout function but uses the back button to go back to the login page. when he logs in with another set of credentials, would a new session start or as i supsect, it would use the original login credentials?
Thanks

You can ignore those three classes in the example. They are not related to the dynamic credential solution, and must have been left over from some other example I evolved into what you see. Sorry to have cluttered up the implementation with stuff that isn't really contributing to the actual solution. DOH!

Have you performed Step 6 from topic "Create the application":

Dynamic JDBC with JHeadstart

Hi I have a problem using jheadstart when appliying dynamic jdbc credentials. I dont know why but my login page comes with errors . the picture of components does not come . for example the submit button comes with no picture but a cross sign (which happens when the picture is not found) and it is same for the other components.
When I remove
<filter-mapping>
<filter-name>ADFBindingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
from web.xml then they come but this time other pages are not found in navigation.
What should I do?
Certainly JHeadstart does override some parameters and this effects my pages. during start up. But I dont know why. You know what is so difficult about these frameworks. You have no knowledge of the underlying mechanism and when a problem occurs you can not figure out its reason . Actually I am complaning that you must write a book about JHeadstart with broader knowledge for users, guys. Without enough documentation you can not make people use it. So just think about it and please help me with my problem.
expecting an answer soon
write back quickly
bye bye

Hi,
First, to reply to your remark about the JHeadstart team writing a book: we did! It's called the JHeadstart Developer's Guide and it's included in the JHeadstart release. Especially Chapter 5, JHeadstart Extensions to ADF Runtime, explains how the ADF Page Lifecycle works and how JHeadstart has extended that with extra functionality and how best practices have been implemented.
Now to your problem with Dynamic JDBC: If the issue is related to the ADFBindingFilter, then it sounds like a generic JDeveloper/ADF problem, not JHeadstart specific. To simplify the test case, you could create a simple drag-and-drop ADF Application, apply the dynamic JDBC credentials to that application and see if the same problem occurs there. Then you can log a TAR at metaLink (http://metalink.oracle/com/), or ask this question at the JDeveloper forum at http://otn.oracle.com/discussionforums/jdev.html.
Hope this helps,

BC4J/JSP Dynamic JDBC Username Audit Trail

I have implemented a BC4J/JSP login page as per the How To "How To Support Dynamic JDBC Credentials". It all works very nicely thank you.
How can I retrieve the application module's username (passed through from the login page) from within the doDML() method of an EntityImpl?
I need to do this in order to maintain an audit trail of db updates.
Thanks,
James

I think I should be able to use something like:
oracle.jbo.ApplicationModule am = oracle.jbo.client.Configuration.createRootApplicationModule

oracle.jbo.ConnectionMetadata cm = am.getTransaction().getConnectionMetadata();
String uname = cm.getUserName();
But when I use this I get the error below. Any ideas?
