JNDI name for resource adapters

When I look up a connection factory via the initial context, which JNDI name should I be using? How do I know which namespace my JCA resource adapter is in?
I have registered the standalone JCA resource adapter via the command
C:\OraHome_2\dcm\bin>dcmctl deployApplication -f my.rar -a my_jca
Can I access it like this from my EJB?
Context initialContext = new InitialContext();
jcaConnectionFactory = (ConnectionFactory)initialContext.lookup("my_jca");
or does it have to be java:comp/env?
The default oc4j-ra.xml that was generated by dcmctl looks like this:
<?xml version="1.0"?>
<!DOCTYPE oc4j-connector-factories PUBLIC "-//Oracle//DTD Oracle Connector 9.04//EN" "http://xmlns.oracle.com/ias/dtds/oc4j-connector-factories-9_04.dtd">
<oc4j-connector-factories>
<connector-factory location="" connector-name="my_jca">
</connector-factory>
</oc4j-connector-factories>

What is the correct way of looking up a resource adapter from another resource adpater? The JNDI name of my resource adapter is "StorageFactory" and I am doing a lookup like:
          Context ctx = new InitialContext();
          ctx.lookup("StorageFactory")
          Is this a correct way to lookup?

Help needed on allocating a JNDI name for MYSQL on Glassfish

Hi,
I am trying to invoke my database (MYSQL) through a JNDI lookup on GlassFish Server. I copied the MySQL connector into the GLASSFISH_HOME/lib directory and went into Admin console (http://localhost:8080/login.jsf) to create a ConnectionPool. After this, I am not sure what I should do, inorder to associate a "jdbc/mysql" JNDI name for this pool. Can anybody point me to what has to be done?
Thank you.

Figured it. After you've setup your pool, you need to go to Resources -> JDBC -> JDBC Resources and then create an new mapping of the pool that you've just created to some name (ex: "java/mysql"); This should integrated Glassy with Mysql
Thanks.

Specify JNDI Name For EJB Module

Hi folks, please I need to know how I can specify the Jndi name for an ejb module I am creating in netbeans 5.0, to be accessed by a web application.
If this can be done using the sun java system application server 9 admin consle (just as for JDBC Resources), i'll also like to know how.
Thanks.

Thanks Jay. I went through the links, it seems that if you have the JNDI name set in the weblogic-ejb-jar.xml, there is no need to set the same in the weblogic admin console. I am using ejb 2.x version. Particularly if you get the WLInitialContextFactory in your code , then there is no need to set the JNDI name in the JNDI tree in weblogic admin console.
Like:-
Context ctx = null;
java.sql.Connection conn = null;
Hashtable<String,String> ht = new Hashtable<String,String>();
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL,"t3://localhost:7001");
This will take care of JNDI tree, hence there is no need to set the JNDI name explictly in the weblogic admin console.
Please correct me if i am wrong. Whether for datasource also whether we can do the same, by setting the resource-ref with datasource in the ejb-jar.xml and not set anything in weblogic admin console? Thanks.

Deploytool: Can't specify a JNDI name for RA

Using j2eesdk1.4_beta2, it appears there is no way to specify a JNDI name for a Resource Adapter. Is there a default name I can use to look up my RA if I don't specify a name? The Deploy Tool help describes some tabbed panes appear to be missing from the appication. Is there a way to work around this problem until the final release comes out?

Headache!... That's what is expecting you in the DeployTool.
The deploytool generates invalid deployment descriptors for Resource Adaptors.
As you mentioned, it doesn't allow you to select a ResourceAdaptor implementation. In my case, I'm using my own Connection and ConnectionFactory and it didn't allow me to choose an implementation class for either interface neither.
I solved these problems by downloading XMLSpy and using the XML Schema to fill-in the gaps in the ra.xml descriptor. There I had also to include other mandatory elements that where not written by the deployTool, like: <display-name>
<vendor-name>
<eis-type>
<resourceadapter-version>
Regarding to the <<null>> error, it has to deal with an invalid sun-ra.xml. It's either empty or it's missing a mandatory element. I used again XML Spy here to give a JNDI to my adaptor.
I thought I was through it but I still can't deploy on the server. When I try, I get the following error:
<[INFO][j2eesdk1.4_beta2][][][12][javax.enterprise.system.tools.admin][03.november.2003 22:16:22:351 CET][ADM5604:Processing config change [Domain:add to xpath=/domain/applications

So far I haven't found a way to get solve this one. The <NAMESPACE_ERR> makes me think about the infamous 'locale' error of the deploytool, but I included the JVM parameters [USER_LANG=en,USER_REGION=US,USER_COUNTRY=US] in the server startup and it didn't change anything.
If you get further than that, please let me know.

Gerard.

Looking up JNDI names for local client

Sir,
I have been trying to look up JNDI name for the local home interface in the client program.But I got only "javax.naming.NoInitialContextException".I want information about to give a JNDI name for EJB and its details.
Thanking you.
Yours,
R K Ramesh

It sounds like you are not specifying the right URL or username/credentials to get an initial context.
A typical example would be something like this:
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, "t3://server:port");
InitialContext ic = new InitialContext(p);
(You can also use a properties file or system prpoerties to specify these.)

JNDI name for TransactionManager?

What is the JNDI name for TransactionManager on Oracle9ias? I thought
it was "java:comp/UserTransaction" but everytime I try to get the
TransactionManager I get a javax.naming.NamingTransaction, root exception is java.lang.NullPointerException. Any help would be appreciated. :-)
TransactionManager trans = null;
String name = null;
try {
InitialContext ctx = new javax.naming.InitialContext();
name = "java:comp/UserTransaction";
trans = (TransactionManager) ctx.lookup( name );
out.println("<p>*** class of TransactionManager is: " + trans);
trans.begin();

Srini,
You mention EJB client -> is the EJB an entity bean? Is it BMT or CMT? If its an entity bean with CMT then you cannot (and should not) be starting the transactions. If however this is BMT then you can use a Sesssion Bean to start and commit the transaction.
I have a feeling that you are using a remote client to access the EJB and then would like to start and commit a transaction. I would like to point out that this kind of transaction demarcation is not supported in OC4J. Here is quote from the OC4J documentation:
"Client-side transaction demarcation is not supported in the application client container: OC4J does not support client-side transaction demarcation. This form of transaction demarcation is not required by the J2EE specification, and is not recommended for performance and latency reasons."
I would recommend that you start using SLSB instead of remote clients.
Hope this helps.

Could take the same JNDI-names for both tags: jndi-name and local-jndi-name

Hello!
I try to design the weblogic-ejb-jar.xml descriptor and I ask myself, if I could
take the same JNDI-names for both tags:
<jndi-name> and <local-jndi-name> ?
Could you give me and advice if this is ok?
Thanks

if you have two separate interfaces, you cant bind them to the same jndi
name. you will have a local home that extends EJBLocalHome and a remote
home called EJBHome. also you need to know which one you are looking up
so you can cast it properly, and use it property (remote interfaces need
PortableRemoteObject, remote parameters are passed by value, ...)

Mapping of logical resource-name to absolute jndi-name for data source

Hi,
I am using SJS AS 8.1. I do a lookup for datasource using logical name specified in ejb-jar.xml using resource-ref element as below :
<resource-ref>
        <res-ref-name>jdbc/db-resource</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
        <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>jdbc/db-resource is mapped to absolute jndi name 'jdbc/jndi-db-resource' in sun-ejb-jar.xml as below :
<resource-ref>
        <res-ref-name>jdbc/db-resource</res-ref-name>
        <jndi-name>jdbc/jndi-db-resource</jndi-name>
</resource-ref>I have configued data source using admin GUI with JNDI name jdbc/jndi-db-resource. When I do a look up of datasource as below :
initalContext.lookup("jdbc/db-resource"); from the EJB I get NameNotFoundException. How do I configure logical datasource name using admin GUI ?
Thanks,
Manisha.

Hi Manisha,
When doing a lookup of standard j2ee connection factories like jms or jdbc "java:comp/env" need to be prefixed.
initalContext.lookup("jdbc/db-resource");
need to be
initalContext.lookup("java:comp/env/jdbc/db-resource");

How to setup JNDI Name for Oracle Apps adapter?

Hello,
I am learning Oracle SOA 11g and trying to do some tutorial on Oracle Application Adapter. I know how to configure JNDI for DBadapter and I did that successfully. I followed same steps to create New JNDI for Oracle Apps Adapter.
1. I Created new data source using Path Services->Data Sources -> New Genric Data Source. Connection to database was successful and created new JNDI Name: jdbc/PKDTAPPS.
2. Then Deployment-> OracleApps Adapter-> Configuration-> Outbound Connection Pools -> New and created JNDI Name eis/Apps/PKDTAPPS.
However I did not find newly created JNDI Name in step 2 under Deployment-> OracleApps Adapter-> Configuration-> Outbound Connection Pools -> javax.resource.cci.ConnectionFactory.
Please let me know if am I following correct steps to create new Oracle Apps Adapter JNDI Name or not.
Since above approch did not work I created new JNDI for DBAdapter with same database connection details. And then latter on use that JNDI Name while creating Oracle Application Adapter in JDeveloper composite. And it allowed me to access Oracel Apps open interface. However while deploying the application it gave me following error.
<Feb 16, 2015 10:50:59 AM CST> <Error> <oracle.integration.platform.blocks.deploy.servlet> <SOA-21537> <Sending back error message: There was an error deploying the composite on AdminServer: [JCABinding]

Since I have no past experience kindly suggest me what is right way to do this.
Thanks,

Hi shri,
Can you check the targets of oracle apps adapter that is it deployed on both cluster and admin server both.

Format of the JNDI name for lookup in DataSource

Hi
a) I have made a datasource in Weblogic 10.3 called SQL and its JNDI name as jdbc/SQLDS.
The driver was BEA'S Type 4 Driver for MS SQL Server
Now I am trying to lookup the datasource through an application. I have used the following
lines of code:
InitialContext context = new InitialContext();
DataSource ds = context.lookup("jdbc/SQLDS");
Connection conn = ds.getConnection();
The Application was a success.
I saw in some articles that you can refer to the datasource by even java:comp/env/jdbc/SQLDS,
instead of just jdbc/SQLDS. I tried both ways and I was able to run the application.
b) Then I made another datasource in Weblogic 10.3 called SQL1 and its JNDI name as jdbc/SQL1.
The driver was MS SQL Server Type 4 Driver for versions 2000, 2005
Now I am trying to lookup the datasource through an application. I have used the following
lines of code:
InitialContext context = new InitialContext();
DataSource ds = context.lookup("jdbc/SQL1");
Connection conn = ds.getConnection();
The Application was a success.
I saw in some articles that you can refer to the datasource by even java:comp/env/jdbc/SQL1,
instead of just jdbc/SQL1. I tried the first way and it didnt work. It gave me a NullPointerException
at the line Connection conn = ds.getConnection();
c)Then I made a 3rd datasource in Weblogic 10.3 called SQL2 and its JNDI name as jdbc/SQL2DS.
The driver was MS SQL Server Type 4 Driver for versions 2000, 2005
Now I am trying to lookup the datasource through an application. I have used the following
lines of code:
InitialContext context = new InitialContext();
DataSource ds = context.lookup("jdbc/SQL2DS");
Connection conn = ds.getConnection();
The Application was a success.
I saw in some articles that you can refer to the datasource by even java:comp/env/jdbc/SQL2DS,
instead of just jdbc/SQL2DS. I tried the first way and it didnt work. Again, it gave me a NullPointerException
at the line Connection conn = ds.getConnection();
I was confused why the 2nd and 3rd way didnt work . Is it becaue I used Microsoft's MS SQL Server Type 4 Driver?
I have added the jar file in the WEBLOGIC_CLASSPATH. Why is it not recognising java:comp/env/jdbc/SQL2DS ?
I would be grateful if somebody could give me ideas on this...
Thanks
Neeti

To use application scoped or indirect JNDI lookups (i.e. java:comp/env/...) you usually need to define a <resource-ref> entry in your deployment descriptor(s). Not sure what type of application you are using to test (web-app, EJB,) but for java:comp/env/ lookups to work, you need to define resource references. The fact that your first test succeeded is somewhat strange. Without the resource reference definitions, I would have expected your JNDI lookups to fail with a NamingException instead of the lookup returning NULL for the datasource.
Assuming you are doing your test from a web-app, you need to add <resource-ref> definitions to your web.xml file similar to the following:
<resource-ref>
<res-ref-name>*jdbc/SQL2DS*</res-ref-name>
<res-type>java.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
and then add <reference-descriptor> definitions to your weblogic.xml file similar to the following:
<reference-descriptor>
<resource-description>
<res-ref-name>*jdbc/SQL2DS*</res-ref-name>
<jndi-name>*jdbc/SQL2DS*</jndi-name>
</resource-description>
</reference-descriptor>
Once you do these steps your lookup("java:comp/env/jdbc/SQL2DS") should function properly from within your web-app.

Dynamic JNDI name for database adapter in BPEL

Hi All,
I am having some major issues trying to make the JNDI location for the database adapter dynamic (10.1.3.4). I already went through the followin link, but that didnt work for me: http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html
The below example works, but only the first run. Second time around the first runs JNDI value gets retained and connects to that database.
This is what worked atleast the first time.
I parameterized the JNDI with a variable defined in the partnerlink definition in the bpel.xml
In Bpel. xml
<partnerLinkBinding name="updatetbl">
<property name="wsdlLocation">updatetbl.wsdl</property>
<property name="CONN">eis/DB/na</property>
<property name="retryInterval">60</property>
</partnerLinkBinding>
In the updatetbl.wsdl file
<service name="updatetbl">
<port name="updatetbl_pt" binding="tns:updatetbl_binding">
<jca:address location="$CONN"/>
</port>
</service>
At run time I change the partnerlink CONN variable in embedded Java.
try
Element targetAdapterElement =(Element)getVariableData("Invoke_getFromTbl_OutputVariable","getFromTblOutputCollection","/ns2:getFromTblOutputCollection/ns2:getFromTblOutput/ns2:SRC_JNDI");
getLocator().lookupProcess("JndiIssueTest").getDescriptor().getPartnerLinkBindings().getPartnerLinkBinding ("updatetbl").setPropertyValue ("CONN",targetAdapterElement.getTextContent());
("updatetbl").getPropertyValue ("CONN"));
catch(Exception ex)
addAuditTrailEntry("Error is " + ex);
This works fine the first time, but the second time I run it to look at a different CONN value, it somehow still connects using the first runs value!
If I redeploy or clear the WSDL cache, it works. But we plan to run it multiple times from several environment so manually or programatically clearing WSDL is not the right solution.
Can someone tell me what is the standard process of doing this so it works everytime?
Thanks,
Shaf

Shaf,
Please refer the mail thread for details. If you want I can send you(send me your email id) the sample BPEL process which uses Dynamic JNDI.

JNDI name for a JMB is not replicatet to other servers in the cluster

Getting jndi name for jms queue via jmx?

All,
I'm trying to write a utility that will do a 9.2-style message export against 8.1 I think I have it all figured out except that I don't know how to get the jndi name of a queue or topic via jmx. I'm using jmx to find queues and subscriptions that have messages waiting, then trying to connect to them to siphon off the messages. I can't just browse jndi for any queue I find because I also want to access the durable subscriptions, for which I need the client and subscriptions ids. Is there a way to map from the jms destination runtime mbean to the jndi name? The getDestination() method isn't supported (throws an exception.)
thanks

Hi John,
You can get destination JNDI names by looking up their value in the JMX configuration mbeans rather than the runtime mbeans. The client-id and subscription-name are available on the JMSDurableSubscriberRuntime mbean.

Tom

Jndi name for AqAdaptor

Hi
I have implemented an ESB in Oracle Jdeveloper 11g.
AqAdaptor-> Mediator -> File Adaptor.
The default jndi name which has come up while adding Aqadaptor didn't work. Then I looked iinto the SOADataSource.xml file and saaw that the jndi name was jdbc/SOADataSource. Even with this, when I deploy the ESB, it is giving the error that it cannot recognise the jndi name.
Could anybody tell me if I need to create connection pool for the default adaptors?

Multiple JNDI names for EJB?

If I'm deploying a webapp that references an EJB, do I have to use the same JNDI
name that is configured in the EJB descriptor?
Why can't I reference the EJB using a seperate name (as in some J2EE examples)?
Thanks,
Darren

darren <[email protected]> wrote:

Does the JNDI name referenced in weblogic.xml need to be the same as that defined
in weblogic-ejb-jar.xml? No. ejb-ref mechanism allows you to map an actual ejb jndi name to one used by your
application - so, in theory, system administrator can change jndi names without
touching your application code. You do not see it in the global JNDI tree because
this mapping exists only in the context of your application.
