Different data-sources.xml files for each build

Any thoughts on how to do this:
I have two sets of data-sources. When I deploy the EAR to my stage box, I need to go to the "stage" data source of the other repositories. When I deploy the EAR to my production box, I need to use the production data sources for the other repositories
I am using jdev 10.1.3
There is a single data-sources.xml file - where, currently, I am manually editing the connection strings between deployments.
I am using ant to build the EAR file.
What is a more elegant way to do this?

Use ANT script to build the EAR file.
Have 2 different data-sources file one for production and one for stage.
Based on the environment you want to deploy tell ANT to copy those files into the EAR.
Just a suggestion.

Please advise.
I have followed the instructions in 'EJB Primer' and 'Using Oracle9iAS Containers for J2EE' to no avail. And I can't find any meaningfull data-sources.xml samples. I have been struggling with this for some time.
Is there any other file, do I need to bind anything?
I'd appreciate your assistance.
Thank you

Hi Louiza,
Show us your web.xml and ejb-jar.xml files as well as your
data-source.xml file.

Does JDeveloper deploy the data-sources.xml file?

Hi,
My project has a data-sources.xml file. When I deployed the project, JDeveloper created a .war file. The data-sources.xml file is not in the .war file. How will the application server pick up the data source if the xml file is not getting deployed?
Thanks,
Merced

data-sources.xml configures the datasource with the oc4j server.
A <Application>-data-sources.xml file also gets added for a project to the project directory.

How to dpwnload one XML file for each report row

product_desc varchar2 (2000)
I would like to download on the file system an xml file for each row of the report
the nane of each xml file = <product_id>.xml
thanks in advance

Hi,
You would probably find it better to search on the PL/SQL forum as this is more their area than Apex.
From what I can see in there (and there are a number of examples that would help you), you need to do something like:
DECLARE
vPATH VARCHAR2(50) := '/DEV';
vFILENAME VARCHAR2(50);
vFILE UTL_FILE.FILE_TYPE;
BEGIN
FOR C IN (SELECT PRODUCT_ID, PRODUCT_DESC FROM PRODUCTS)
LOOP
vFILENAME := C.PRODUCT_ID || '.xml';
vFILE := UTL_FILE.FOPEN(vPATH, vFILENAME, 'W');
UTL_FILE.PUT_LINE(vFILE, '<xdr>');
UTL_FILE.PUT_LINE(vFILE, '<product_id>' || C.PRODUCT_ID || '</product_id>');
UTL_FILE.PUT_LINE(vFILE, '<product_desc>' || C.PRODUCT_DESC || '</product_desc>');
UTL_FILE.PUT_LINE(vFILE, '</xdr>');
UTL_FILE.FCLOSE(vFILE);
END LOOP;
END;I haven't included exception handling etc and you should check on the PL/SQL forum to see if there are better examples!

SDDM 3.3.EA2 one xml file for each table?

Dear Philip!
We'd like to have xml-files for all of our tables. To be more precise one xml file for each table so we can check it in in our configuration management system (CCC Harvest)
Is it possible to write such a transformation script and, I really believe that can be done, can you please point us in the right direction, how to do that?
Thanks in advance
Guenter

Hi Gunter,
if you want each table to be stored in separate XML file then you needn't to do anything. Each table is stored in separate file in design directory structure - foreign keys are not included, each FK is stored in separate file.
The ID of the table is used as file name. Each table has presentation in each physical model so you'll find file with same name (table ID) in each physical model.
Please elaborate on that if you want something else.
Philip

10.1.3 Migration Issue with data-sources.xml

Hi:
Running into lots of migration issues for an application built in 10.1.3 EA, migrating to 10.1.3. production, mostly in the BC project. Here's one: the database connections built in EA were not carried over to prod, so they needed to get re-built. No biggie. But now the data-sources.xml file in the model project has duplicate entries for my data sources. I have tried directly editting that file and removing the duplicates, but when I go to run my application (ADF Faces & ADF BC) JDeveloper hangs. When I abort JDev and re-start it, the duplicate entries are back in data-sources.xml (and yes, I did save the file after making the changes). It seems that the xml file is built dynamically from definitions stored elsewhere. Where is the source? What will I need to modify to get the changes to take?
Thanks.
Johnny Lee

There is new control over when/whether JDeveloper add/updates your data-sources.xml file for the embedded server. The settings are located here:
Tools | Embedded OC4J Server Preferences | Current Workspace | Data Sources
There are some settings there that control whether/when we update the data-sources.xml

[HELP] data-sources.xml on META-INF for deployment

Hello,
I'm having a problem in the configuration of POOL OF CONNECTIONS, I created the file and data-sources.xml orion-application.xml, and I am not able to add the same folder META-INF when I create the deploy the application (EAR). What can I do for the time that I generate the deploy the files have to go to the right folder.
Thank now ...
I am using:
JDeveloper 10.1.3.3

If application is to run on embedded OC4J, a EAR file is not required.
1. Create a datasource, either declaratively in the data-sources.xml file or in the Connections Navigator or in the Global/Project DataSources.
2. Specify the data source in the application.
3. Run the application in the embedded OC4J.

Use of cache_scheme in data-sources.xml

Hi guys.
I have posted a couple of similar topics before - without any response ! I can't believe with all of the gurus out there that NOBODY knows the answer to this ! :-)
Anyway, we are providing a 'vanilla' type implementation of Oracle's Connection Pooling - just using Oracle's DataSource to open and close connections, and having Oracle dynamically take care of the pooling itself. ( Apparently, under this scenario, even max and min connections are set as required ).
However, if I specify the cache_scheme property within data-sources.xml, will it take effect using this basic implementation ? In other words, will changing it's value effect the behaviour once the max limit is reached and more connections are requested ?
Many thanks.
Steve.

Timo,
thanks for your respone! I managed to configure the application to use a data-source connection created on the application server. Also in order to be able to deploy the same EAR to a number of containers on different DB's.
I know it's possible to connect to a DB without using a data-sources.xml file .. but it seemed like my application was storing some 'old' connection information because it was able to connect to the db without having the data sources configured on the AS.
Do you need to restart JDeveloper after unchecking the 'Bunde default data-sources.xml during deployment' checkbox? Because it is working correctly right now ... .
Thanks,
Koen Verhulst

Problem using JDBC (JNDI) DataSource and data-sources.xml w/ OC4J

I have a JClient application developed in JDev X. It works fine when using a JDBC URL for the connection (which then writes the connection into the BC4J.xcfg files, one for each application module). However, I would like the app to retrieve the data source from the server's data-sources.xml file. However, when, on the configurations tab of the application module I set the connection type to JDBC DataSource, and give it the JNDI name, it does not work, either with the embedded OC4J or the stand-alone OC4J. Any suggestions???
In the stand alone OC4J I verified that the data source exists (using java -jar admin.jar ormi://nemethzoltan3 admin welcome -application adatklinika -testDataSource -location jdbc/adatklinikaCoreDS) ... so the data source is defined in the data-sources.xml. Of course the error I get is JBO-30003.
If I just try to "test" the data source in Jdeveloper (using the context menu of the app module, and setting it to use the adatklinikaCoreDS) I get a JNDI error: unable to lookup data source and at level 3 a "javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I checked, the data source is defined under tools->embedded OC4J properties->data sources.
If I try to run the main form, simply nothing happens.
Please help!!!

Ok, figured out why running from jdeveloper wasn't working: the embedded OC4J server wasn't started (start it by running an html page from your project or something...and make sure you don't have a stand-alone oc4j running). AND more importantly it didn't have the library "embedded oc4j client" library included (project properties -> profiles -> development -> libraries)...which is needed for whatever reason.
Now to try and get it working with the stand-alone OC4J...

How to prevent data-sources.xml from being included in EAR

I cannot get rid of the data-sources.xml file in my EAR file in the meta-inf folder.
Deselecting the "Bundle Default data-sources.xml during deployment" in my preferences didn't have any effect. I also tried shutting down/restarting JDeveloper just in case it was cached.
I also tried adding an exclude filter for data-sources.xml in my deploy profile for both Web files and WEB-INF/classes.

The way I resolved this was to create the data-sources.xml, right click it, select Properties then uncheck Auto-update data sources.xml. That way it stays empty (hopefully).

OC4J data-source.xml other data base like postgresql

Hi i need to use a DataSource in OC4J with other database (any), i am setting the data-source.xml like:
<\datasource
class="com.evermind.sql.DriverManagerDataSource"
name="DSPropiedades" location="jdbc/DSPropiedadesCoreDS"
xa-location="jdbc/xa/DSPropiedadesXADS"
ejb-location="jdbc/DSPropiedades"
connection-driver="com.borland.datastore.jdbc.DataStore"
username="sample"
password="sample"
url="jdbc:borland:dslocal:D:/seguridaddb/seguridad.jds"
inactivity-timeout="300"
/>
and i had put the database.jar in the OC4j directory's
D:\ora10i\jdbc\lib
D:\ora10i\j2ee\home\lib
D:\ora10i\lib
but i always obtain the same error
Error initializing data-source 'jdbc/DSPropiedadesCoreDS': DriverManagerDataSource Driver 'com.borland.datastore.jdbc.DataStore' not found

Liliana,
From the [lack of] information you have posted, I am assuming you are using OC4J stand-alone version 10g -- but I'm not sure because I couldn't find any of those details in your post. It always helps to include version and platform information.
If my assumption is correct, then the default location for third-party JAR files (including your JDBC driver) is the
"j2ee/home/applib"
subdirectory of the OC4J installation. For example, on my Windows XP machine (again, I couldn't see what platform you are using, so I am assuming it is also Windows), the actual path is:
C:\OC4J_10_0_3\j2ee\home\applib
If you want to see other examples of "data-sources.xml" files (apart from the one that comes with OC4J), try searching the following Web sites:
http://www.orionserver.com
http://www.orionsupport.com

Good Luck,
Avi.

How Get JDev to Omit data-sources.xml from every .war deployment

I want a global data-sources.xml file to be used for all deployments. I do not want a copy of my standard data-sources.xml file to be included in every single deployment. I want my global data-sources.xml file to reside in the standard J2EE location of:
oc4j_home/oc4j_instance_name/j2ee/config/data-sources.xml
JDeveloper, for whatever reason, includes a data-sources.xml into every .war file. How do we configure JDev to omit the data-sources.xml? How do we set up JDev to automatically configure the .xml files (orion-application.xml, application.xml, etc) to use the global data-sources.xml? I do not want to manually do this for every deployment.
I've been trying hard to find the answer in JDev online help and other OAS manuals. I read everywhere that I can have a "global" data-sources.xml, but I find no way to easily configure JDeveloper to do it this way.
I would be grateful for you insights/help.
thanks
-Paul Janda

I found the answer:
In JDeveloper, Go to Tools | Preferences
Select Deployment
Uncheck the option for "Bundle default data-sources.xml during deployment"
Upon the next generation of the .ear or .war file (including the next deployment), data-sources.xml will be omitted.

Data-sources.xml instead of bc4j.xcfg

Please give me some direction on how I can configure my Application Module to use JNDI lookup of my data-sources.xml file instead of using the bc4j.xcfg file. I know there is a way but I need a step by step process to get this done through configuration while developing in the IDE.

Can you please tell how did you solve that. I have similar problem

Missing data-sources.xml deploying war with jdeveloper 9i RC

When deploying a war file to an OC4J 1.0.2.2.1 server and error reports during the deployment that data-sources.xml is missing in the application-deployments/xxxx directory. Only the orion-application.xml file is present - which references a data-sources.xml file in the same directory. The problem is : it isn't there.
When I copy the xml files from the applications/xxxx directory to the application-deployments/xxxx directory and redeploy the war file everything works fine.
Is this a configuration issue or a bug ? Anyway, can somebody tell me how I can work around this problem ?
Thanks !

this is a bug and you have already found the workaround.
