Getting JDBC data source from PersistenceUnit

I have an application accessing a database, and am using JPA to read/write/update records in the database.
Some of the database tables use stored procedures to perform complex computations across entire
database tables, and I need to call these stored procedures when I the user does certain operations,
such as cloning an object and all its associated data. To call the stored procedures I use the same
JDBC data source that is used to define the PersistenceUnit.
Is there any way to get that DataSource from the PersistenceUnit?
Since I do not know how to do this I am currently using @Resource DataSource annotations to get the JDBC
datasource. That is ugly because I have the datasource specified in two different places in my code.
Please help!

I hit the same problem as yours. This issue is caused by JDK version. The JDK used by Weblogic 10.3 is java 6, while your client program's jdk version is java5. So change the both of them to java 6. This issue will be fixed.
Don't forget to rebuild the wlfullclient.jar which also should be java 6.
Good luck!

Standalone application can't get JDBC data source from Weblogic 10.3

We have the following configuration :
A Weblogic server 10.3 (default installation).
The server contains a JMS queue (jndi name: "DMQ") and JDBC data sources (jndi names: Oracle thin XA - "dataSource", MS SQL - "dataSource1")
We have built wlfullclient5.jar for Java 1.5 ([http://edocs.bea.com/wls/docs103/client/jarbuilder.html#wp1078122]) (according to the docs)
And now we use a test standalone application with the wlfullclient5.jar :
public static void main (String[] args) throws NamingException {

Hashtable<String, String> env = new Hashtable<String, String>(); \\ env.put(Context.+INITIAL_CONTEXT_FACTORY+, "weblogic.jndi.WLInitialContextFactory"); \\ env.put(Context.+PROVIDER_URL+, "http://serv1:7001"); \\ env.put(Context.+SECURITY_CREDENTIALS+, "weblogic"); \\ env.put(Context.+SECURITY_PRINCIPAL+, "weblogic"); \\ InitialContext ic = new InitialContext(env); \\ \\ System.+out+.println("Get DMQ"); \\ ic.lookup("DMQ"); \\ System.+out+.println("Get dataSource"); \\ ic.lookup("dataSource");
bq. System.+out+.println("Get dataSource1"); \\ ic.lookup("dataSource1"); \\ System.+out+.println("Done"); \\
Here is the output when connected to WLS 10.3:

Using WLST to set up credential mapping on JDBC Data Source

I am wanting to write a script (WLST) to set up a large initial set of credential mappings on a JDBC data source.
I can create the datasource and do all the basic set ups, but I can't figure out how to do the credential mappings.
I tried the "record" option from the Admin console, but it created a script that says that credential mappings are not recorded.
This is the mapping function that you get to from the "Security" tab on the DataSource page, and then the "Credential Mappings" tab. This allows you to map a "WLS user" to a "remote user" - which in my case is an Oracle OLS user.
I am using Weblogic 10.3
Can anyone point me to a set of commands which can perform this function?
Thanks!

I wonder if there isn't a publicly visible MBean for the credential mapping. That would explain why the recorded script doesn't have the mbean method invocations.

JDBC Data Sources: Potential Issue with JDeveloper 10.1.3.4

I think I found a bug or issue with the latest JDeveloper 10.1.3.4 release when using JDBC Data Sources on the Embedded OC4J container.

Or if I use a simple drag and drop ADF Faces Table:

I also tried this on a different computer using a fresh install of JDeveloper just to make sure that the copy of JDeveloper that I downloaded didn't have a fluke in it.
Thanks!

M. Ruston,
It must be something on your side. i just tried the same thing using the employees table from the HR sample schema (it has a date column). It works with JDBC URL and datasource both.
Just out of curiosity - if you look at the properties for your Business Components project at the business components section, what does it show for the SQL Flavor and Type Map?

WLS 10.3.4: How to use OS authentication for JDBC Data Source

Hello all,
As a preface, I've tried searching the forum/Google for "OS authentication" and reading the WLS JDBC doc to no avail - if it's documented somewhere, a RTFM link would be much appreciated.
I'm trying to set up a JDBC data source on WLS that leverages the OS Authentication capability of the Oracle database. If it would help, I can go into the reasoning behind why I want to do this, but basically, it's to simplify the config/deployment of a COTS application. What I have in the database is an "identified externally" user that corresponds to the OS user that is running the WebLogic Server. Normally, in tools such as SQL*Plus, I would use "/@db" as the username/password (in other words, no username and no password specified), and I would be logged in as the "idenfitied externally" user. I want to configure the same thing for a WebLogic Data Source, but if I leave the username/password blank, testing the connection in the WLS console gives me "invalid username/password, login denied" I've also tried using "/" as the username, as was documented in a quite old WLS faq, but that gives me the same result.
Is there some magic switch I need to flip?
Thanks,
John

Hi John, there's no way to do that with connection pools, which is how WLS datasources get their
connections, or middleware in general. WebLogic would have no way of knowing which if any of the
pooled connections was appropriate for the current 'user', which is not the application user, but
instead is the OS identity of the person who started the WebLogic server! If you start up your
WebLogic server, and people start pointing their browsers to it, doing various stuff, the OS knows
you started WebLogic, and maybe with the help of OCI, Oracle's JDBC might know it was you who
started WebLogic's OS process, but what does the OS know about any user that may be running
a browser or application elsewhere (even if on this same machine), when that browser or application
connects to your WebLogic server process?
HTH,

How I can to do get a data sources on sun appserver 8 like this?

jsc GUI develop jsf pages ,I want to get a data sources by Context lookup jndi have binding data sources.
I know weblogic to get this.
such as :
Context ctx = null;
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
p.put( Context.PROVIDER_URL, "t3://localhost:7001" );
p.put("java.naming.security.principal", user);
p.put("java.naming.security.credentials", pwd);
ctx = new InitialContext(p);
ds = (DataSource)ctx.lookup( "myds" );
do you tell me sun appserver 8 how to implements this?thx.

HI
I am not clear what you are looking for but let me try to give you something. Yes it is possible to get DataSources on apserver 8 by registering JDBC Connection Pool and JDBC DataSource in the admin gui. You can use the regisred datasource in your code like this
InitialContext ctx = new InitialContext();
dataSource ds = (DataSource)ctx.lookup( "jdbc/myds" );
OR
if you are looking for the Creator do all these, here is the way.
Create a datasource in the server navigator to point to any of your database. Drag and drop a table to any of your pages in the application (This is not neccessary if any of your application pages have a rowset/datatable already).
Deploy the application then the datasource will be registered into application server 8. You can use the same code now to access the datasource
InitialContext ctx = new InitialContext();
dataSource ds = (DataSource)ctx.lookup( "jdbc/myds" );
Please let me know if you are not looking for above .
Thanks

Need Help on using CAS Incremental Crawl with JDBC data source

Hi,
As part of one of the e-commerce implementations, we are implementing a delta pipeline which reads the data from the database views. We plan to crawl the data with the help of CAS JDBC data source. In order to optimize the data reads, we want to use the CAS capabilities of incremental crawl. We rely on CAS to be able to identify the updates available in the subsequent incremental crawl and only read the updated data for any given crawl unless we force a full crawl.
We have tried implementing the above setup using JDBC data source. CAS reads from the database and stores it in the record store. The Full crawl works fine however; we observed some unexpected behavior during the incremental crawl run. Even when there is no change in the database, crawl metrics show that certain number of records have been updated in the record store and the number of updates differ in every subsequent run.
Any pointers what can be the issue ? Does CAS has the incremental crawl capability using JDBC data source ?
Regards,
Nitin Malhotra

Hi Ravi,
Generic Extraction is used to extract data from COPA tables. And delta method used to extract delta records (records created after initilization) is timestamp.
What is this timestamp?
Assume that, you have posted 10 records one after the other to the COPA tables. And we do initilization to move all these 10 records to BW system. Later another 5 records are added to COPA tables. How do you think the system identifies these new 5 records (delta records).?
It identifies based on a timestamp field (eg : Document created on ,a 16 digit decimal field).
Assume that, in our previous initilzation, say "document created on" field for the last (or the latest) record is 14/11/2006, 18.00 hrs. and timestamp is set to the 14/11/2006, 18.00hrs. then when you do delta update, the system treats all the records with "document created on" field is greater than 14/11/2006, 18.00 hrs as delta records. This is how new 5 records are extracted to bw system and timestamp is again set to the new value besed in field in the records.(say 14/11/2006, 20.00hrs)
Assume that, you have two records with "document created on" field as 14/11/2006, 17.55hrs and 14/11/2006, 17.57hrs. and they were updated to the COPA table after 14/11/2006,20.00hrs (at this time last delta load is done) due to some reason. How can you bring these two records? For this, purpose we can reset the timestamp at KEB5. In this eg, we can reset as 14/11/2006, 17.50 hrs) and do the delta again. So, the system picks all the records which are posted after 14/11/2006,17.50hrs again. But remember that, doing this, you sending some of the records again (duplicate records). So, make sure that you sending ODS object. otherwise you end up with inconsistant data due to duplicate records.
Hope this helps!!

Difference between DataSource & JDBC Data Source Factory

Hi,
Can anyone tell me what the difference between a 'DataSource' and 'JDBC Data Source
Factory' is ? I see both these on the Weblogic admin console. I have reviewed
the documentation but it is not clear to me what the difference between the two
is and what situations each on is appropriate for.
Thanks,
Raju

Hi Sree,
I have read literally ALL the online documents related to JDBC Data Source Factories
including the one you provided below, but I still do not understand what they
are for. I have also searched in Google but to no avail.
I will try to be more specific as to where my confusion lies.
1)Why would anyone ever choose a JDBCData Source Factory instead of a Tx Data
Source or plain vanilla (not XA) Data Source? EJBs connect just fine with the
latter 2.
2)What should go inside the properties box?
a) http://e-docs.bea.com/wls/docs70/ejb/EJB_environment.html#resourcefact states
that connection properties should go in here
b)Then, the document goes on to describe a syntax for binding a Connection Pool
to a JNDI name, all in the properties box. I have never been able to successfully
create a data resource factory with a JNDI name. I get no errors, but it appears
no where in the JNDI tree
c)If this mysterious syntax associates a resource factory with an existing Connection
Pool, then why go through all the fuss of redefining the Driver Class Name, URL,
etc., when those are already defined on the Connection Pool?
When you setup either a Data Source or a TX Data Source, WebLogic does not require
that information since it was all setup in the pool. Why is it needed here?
Thanks in advance for you help.

Error in generating data source from planning area

Hi experts! I have an error while making data source from planning area:
after the screen when i fill in the data source name (Window name: Generate export data source) i have the SYNTAX_ERROR Message:
Syntax error in program /sapapo/cl_im_extract_ex======cp
the main reason: the type /BI0/9A0IVWKNDGD is unknown
what you can suggest to solve this problem?
Thanks.

Dear Andrey Kudriavzev,
The reason is the program is trying to use the datatype '/BI0/9A0IVWKNDGD' which does not exist in the system.
Go SE11 to cross check if it exists. Check dataelement radiobutton -> enter /BI0/9A0IVWKNDGD -> Choose display option. You would need to create this datatype in the system. I feel there must some OSS Note related to this.
Search for an OSS Note. Raise one if you cannot find the relevant notes.

I tried mackeeper to recover files but it could not. Any other way any one has tried to recover a system library folder after OS upgrade?

No, it doesn't store a clone. You would have needed to make one with either SuperDuper or CarbonCopy Cloner.
If the files were in your ~/Library folder then they may still be there. As I said, you can access it by
going to your Finder "Go" menu hold the option key to choose "Library". I wouldn't think an upgrade would overwrite anything in ~/Library.
If you have a Time Machine backup you may also be able to use that to retrieve them.

How can I get the data back from my game

How can I get the data back from minecraft if I deleted the app and bought with a different Apple ID

No, they are tied to the ID that purchased them, and cannot be transferred to anyone else.

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
The following is my configuration in the conf\mapViewerConfig.xml:
<map_data_source name="mvdemo12"
jdbc_host="127.0.0.1"
jdbc_sid="orcl12c1"
jdbc_port="1522"
jdbc_user="mvdemo"
jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
editable="true"/>

But it does not work.
After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
Does anyone know it?
Thanks,

For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
//mypdb1.foo.com as described in the README,
- MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
<map_data_source name="myds"
    jdbc_host="foo.com"
    jdbc_sid="//mypdb1.foo.com"
    jdbc_port="1522"
/>
For 11.1.1.7.0 use a container_ds instead.
i.e. instead of using
<map_data_source name="my_12c_test"
                   jdbc_host="mydbinstance"
                   jdbc_sid="pdborcl12c"
                   jdbc_port="1522"
                   jdbc_user="mytestuser"
                   jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
                   jdbc_mode="thin"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
use
<map_data_source name="my_12c_test"
                   container_ds="jdbc/db12c"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
Property
url jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
Add a JDBC resource for that newly created pool
Use that in mapviewerconfig.xml as above

Using JDBC Data Sources with ADFBC, NoInitialContextException

Using JDBC Data Sources with ADF Business Components, NoInitialContextException
I follow the instruction in the link below to create an ADF Swing application using datasource. I am using JDeveloper version 10.1.3.
http://www.oracle.com/technology/products/jdev/howtos/10g/usingdatasources/using_datasources.html
The ADF generated code looks like this:
JUMetaObjectManager.setErrorHandler(new JUErrorHandlerDlg());
JUMetaObjectManager mgr = JUMetaObjectManager.getJUMom();
mgr.setJClientDefFactory(null);
BindingContext ctx = new BindingContext();
ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
ctx.setLocaleContext(new DefLocaleContext(null));
HashMap map = new HashMap(4);
map.put(DataControlFactory.APP_PARAMS_BINDING_CONTEXT, ctx);
mgr.loadCpx("datasource.view.DataBindings.cpx" , map);
final FormMain frame = new FormMain();
frame.setBindingContext(ctx);
I got this error when executing the last line: frame.setBindingContext(ctx);
(oracle.jbo.common.ampool.ApplicationPoolException) JBO-30003: The application pool (datasource.datamodel.AppModuleDS) failed to checkout an application module due to the following exception:
----- LEVEL 1: DETAIL 0 -----
(oracle.jbo.JboException) JBO-29000: Unexpected exception caught: oracle.jbo.DMLException, msg=JBO-27200: JNDI failure. Unable to lookup Data Source at context jdbc/xe_hrDS

----- LEVEL 3: DETAIL 0 -----
(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
If I configure the application module connection type as JDBC URL, everything works.
If the connection type is JDBC Datasource, I got the above error.
Can someone show me how to adjust the generated code by ADF to use datasource?

ADF BC has a bug. With Data Source in Application Module, application module does not connect. Use JDBC Connection URL.
