If you want to change template based on parameter. you have to use below syntax
v_layout boolean
V_LAYOUT:= FND_SUBMIT.add_layout(template_appl_name => 'SQLAP' -- application short name
,template_code => 'HUBAPAPN' -- template name
,template_language => 'en'
,template_territory => '00'
,output_format => 'PDF');
Above can be used in plsql stored procedure before submitting Concurrent Program (Bi Publisher report) or may be you can try to add this code in Oracle reports after report or before report trigger

How execute pl/sql command from Oracle ADF Business Components

this should be similar to how it worked in JDeveloper 9.0.3. hava a look at <JDev903 Home>\BC4J\samples\StoredProc for a code example.

How to change the Schema (DB2, Oracle) in CommandTable at run time

Dear all,
I have a problem as below:
I have created report with CommandTable, then I am using Java and CRJ 12 to export data. So how to change the SCHEMA in CommandTable?
Please help me on this.
Ex: CommandTable is SELECT * from SCHEMA.TableA, SCHEMA.TableB
Thanks,

Dear Ted,
I want to change DataSource, it means the report will be load and change connection at run time (using CRJ SDK) and i want to change the SCHEMA.Tablename in CommandTable in report.
I also use the parameter to do it, but it can not be at run time, just correct when designing.
Could you please help me on this. You can post the code if any.

How to store Custom principal in Oracle ADF security Framework

Hi guys, hope somebody will help me out.
I am facing the following issue, i need to have a custom principal instance after oracle adf security frame work does authenticate and authorize user.
My custom principal instance should have per say addition attribute, say clientId. I am using Jdeveloper 11.1.2.4 and i setup weblogic to use ReadOnlySQLAuthenticator(it does most of desired functionality).
As far as i get it, i would have to implement a custom provider to have a chance to implement a custom LoginModule, so i can set it up to use my custom principal, am i right ? and i am not sure how ReadOnlySQLAuthenticatorImpl that i chose in weblogic is bound to
DBMSAtnLoginModuleImpl (i mean how does it knows what LoginModule should it use) and if i can , how can i make ReadOnlySQLAuthenticatorImpl use my custom LoginModule.
Sorry if i violated forum rules.

and i am not sure how ReadOnlySQLAuthenticatorImpl that i chose in weblogic is bound to
DBMSAtnLoginModuleImpl (i mean how does it knows what LoginModule should it use)
This info is returned by getLoginModuleConfiguration(): AuthenticationProvider (BEA WebLogic Server 10.0 API Reference)

How to change the Program in Oracle Session

When I create or use a JDBC connection, I want to set the value of something 'in' the connection so that it shows when I do a query like:
select SID, Program, Machine, Module, client_info
from v$session
For example, how do I set the 'Client_Info' column of v$session? Or the, 'Program' column?
Or can you do this in JDBC?
I am using the thing 8.1.x driver ( where x = 6, I think).
My server, is 8.1.7.4 on Solaris...
Thanks

Thanks a lot for your answer.
Do you know how to implement that when using the Oracle ADF framework?

How to change datasource location in CR V10

How to change the datasource location in CR10, I need to use same table in different database. I tried in "Set Datasource Location" but it is not updating to the new one which i have selected. please help me on this.
Thanks,
S Aravind.

Hi Try like this,
Go to the Database option on the top > Select Set data source option.
The top portion of the Set Data source Location window shows the current connection and part at the bottom is where you would make a connection to the new database
Once the connection has been made, select 'one' table from the current connection and then select a matching table in the new connection and click on the 'Update' button. Do this for all the tables one by one.

Jdeveloper 11g: how to change the extension library Oracle JDBC

Hello
We use JDeveloper 11g for our desktop (swing) projects. When I debug the project in IDE, the classpath includes this jar: C:\Oracle\jdevstudio1117\oracle_common\modules\oracle.jdbc_11.1.1\ojdbc6dms.jar
The ojdbc6dms.jar is in Oracle JDBC extension library. We actually want to use ojdbc14dms.jar as our jdbc library jar. I exclude the ojdbc6dms.jar in the project classpath setting and add a user library for ojdbc14dms.jar. When I run the project, the IDE still use ojdbc6dms.jar in the classpath. I try to use "Manage Libraries" under "Tools" menu to change the jar file in Oracle JDBC extension library, but it cannot be changed.
Can I ask how to change ojdbc6dms.jar to ojdbc14dms.jar in Oracle JDBC? Or, how can I let the IDE not use ojdbc6dms.jar when I run the project? Thank you
Leaf

Replace the ojdbc6dms.jar with ojdbc14dms.jar in C:\Oracle\jdevstudio1117\oracle_common\modules\oracle.jdbc_11.1.1
The ojdbc14dms.jar may be required to be renamed to ojdbc6dms.jar in the C:\Oracle\jdevstudio1117\oracle_common\modules\oracle.jdbc_11.1.1 as the pre-configured settings are for ojdbc6dms.jar.
