How to bind to a datasource at deployment time ?

Hi everyone,
I have a ear file in which the application.xml file specify multiple <module> entries.
Each <module> (jar) containing multiple session beans.
Each ejb is accessing the same database schema by using the same datasource.
When accessing the datasource, I lookup in the JNDI.
I'm trying to keep it portable so I want to make the binding between the logical reference and the physical one at deployment time.
I found that I can put a <resource-ref> entry in the ejb-jar.xml and in the web.xml file, so the container can do the mapping I want to do.
Here's my question:
Is there another way than repeating again and again the same <resource-ref> entry for all my ejbs and do the same bindings for all of them ?
I find it can lead to errors if I forget to bind only one. Is there a way to specify this only once for the entire application and use it for the binding ?
I'm using OC4J 10.1.3.0
Thanks

Hi,
If you delete the corresponding source system from RSA1, it will delete all the datasources as well as all source system dependend objects, such as PSA, transfer rules, etc.
But if this doesn't suit you, perhaps just use CTRL key to select multiple datasources, and then choose delete from the context menu.

Create a datasource at deploy time

Hello. I'm new to EJB3.
I've developed an application with a datasource (JAVADB) running on netbeans 5.5.1 and sun application server 9. It works well.
Next y try to deploy the .ear file into another application server and get the error "can't find jndi datasource". That's Ok, because this datasource doesn't exist on the second application server. How can i create a new database and datasource while deploy the .ear file?
Thanks.

Hi, thanks for your help!
I'll try to explain my problem again.
I have netbeans 5.5.1 and i've already configured a datasource so my application can use it.
The problem comes when i try to deploy the ear file into another app server that have not already configured the datasource that my application use. And i cant create it manually because it is on in my client's pc.
At this point, what i really need is create a datasource while my .ear file is deployed. The current solution that i've found is to use ant. Is there another?
Thanks a lot!

How can I look up DataSource from one EJB to the other EJB?

Image that, I have 3 databases:
DB1
DB2
DB3,
And then, 03 DataSources is deployed in DS EJB, named DataSource1, DataSource2, DataSource3.
In the other App EJB, I have Connection Management function, as follows:
public Connection getConnection(databaseKey) {
if (databaseKey.equals("DB1")){
connection = remote.lookup("DataSource1");
}else if (databaseKey.equals("DB2")){
connection = remote.lookup("DataSource2");
}else if (databaseKey.equals("DB3")){
connection = remote.lookup("DataSource3");
return connection;
How can I access DataSource 1,2,3 from the other EJB? How to config EJB server for that?
Thanks in advance!
Now, I have the other App EJB. Some class will require one of the above DataSource from DS EJB through function getConnection(databaseKey){}

I strongle suggest you to use a ServiceLocator for this . It will be very easy to identify.Go to the sun home page and look for a servicelocator pattern.You can even directly use that code for you.

How to specify JDBC Oracle url using deployment tool - Entity Bean

Hello I'am new to EJB.
When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
and password to establish a connection object, how does one specify that in the deployment
tool?
Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
private String dbName = "java:comp/env/jdbc/AccountDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
what would my dbName be at the top?
Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
In the Resource Factories Reference Code I've add a reference of
Coded Name: jdbc/dev
Type: javax.sql.DataSource
Authentication: Container
and down the bottom of the I've put JNDI Name: MyAccount
according to the AccountClient code of:
Context initial = new InitialContext();
Object objref = initial.lookup("MyAccount");
and put User Name of "system" and Password of "manager"
I'am sure in the source code I have to put
Class.forName("oracle.jdbc.driver.OracleDriver")
else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
Please help
Thanks

How to change the Data sources after deploying the application ??

Hi All,
i want to know how to change the Data sources after deploying the application to the application server ???
I'm using Oracle Application Server 10g Release 3 (10.1.3.1.0)

Can you access the Enrprise Manager website of the target Application Server from your location? If so, you can change the datasource in it. If not, yo can bundle the datasource definition in your archive and use that one instead of the one configured in the target OC4J container. Or this will just be the responsability of your customer: whenever you send a new WAR file, they have to modify the datasource if needed and deploy the application?

[SOLVED] Simplest way to change datasource before deployment

Hi all,
I'm working with ADFBC on Jdev 10.1.3. My web app works correctly in my development environment, but now i need to put it on the production environment. That means changing the address of the datasource and deploying the app without having Jdev directly connected to the server.
I've produced the .ear and .war then deploy them without difficulties from the OAS EM. But after make the correct changes on the Jdbc connection pool and datasource, then restart OAS (10g), i cannot connect to the DB. It seems that each one of my app module is associated to a bc4j.xfg which still contains the old connection parameters to DB. And so it seems the Jdbc ressources available in the OAS (created from the data-sources.xml) are not in use.
My questions are how to easily modify these files (with avoiding to make it manually)?
Should i use some toplink features to obtain an unique file containing connection parameters? Or may be i've missed something in the deployment descriptors (clearing bundle datasource?) or in the project properties?
I've probably miss something easy because i can't found a lot of threads dealing with that.
Thanks in advance,
Regards,
Tif

Klee,
It seems that you can choose the datasources you want to include with your deployment.
In Jdev select your application, then go Tools> Embedded OC4J preferences. Select current workspace, then click on Data sources. Here is a check box "Auto-update data-sources.xml ...", clear it. Then drill down Data sources and delete all the things you don't need, just save with clicking on OK. Now save all. You can test with going back to current workspace data sources, after selecting one of the project included in the app. It should display only the data sources you have decided to keep.
I didn't try to re deploy for the moment but i assume that only these data sources should be deployed.
Hope it works,
Regards,
Tif

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:

<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>

This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>

'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on

'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.
Warm Regards,
Arun

How to bind a UI element to the context

Hi Experts,
 I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
 IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
 IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
 IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
 IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
 header1.setText("Tab1");
 tab1.setContent(in);
 ts.addTab(tab1);
 IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
 IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
 IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
 header2.setText("Tab2");
 tab2.setHeader(header2);

From these exceptions what i understood is, i need to bind these UI elements to context.
 Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,
Murthy.

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
include this in your code ,
let me know if you face any problem

How to bind an aggregated list to a variable in an IN or ANY clause

Hello, and thank you for helping -
I have a process that involves a parameter assertion, the result of which is a string for an IN or ANY clause. I am not able to figure out how to bind the result of the assertion to to executable SQL. The actual business process is long and laborious and, I decided, not worth explaining for the purpose of this forum. I have abstracted the process into some dummy data. The goal is to bind v_any_condition to :a. I could certainly build the SQL without the binding, but I would be very interested to know just the same what I am missing here (I'm sure something simple, or just a basic SQL rules that I have missed).
Thanks!
DECLARE
-- The goal is to bind v_any_condition in an ANY clause

-- DBMS_ASSERT.ENQUOTE_LITERAL('9')||','||
-- DBMS_ASSERT.ENQUOTE_LITERAL('d');
v_sql varchar2(2048);
-- We'll create a simple cursor of VARCHAR2(1) just like DUAL.DUMMY
rc sys_refcursor;
rc_record dual%ROWTYPE;
v_counter NUMBER DEFAULT 0;
BEGIN -- Build the SQL. In this example, we decompose an aggregated string

Superb. Thank you very much.
For anyone who is interested in the solution I chose, here is the revised SQL that accepts a list as a bind variable after casting the list as a table. The "split string" code is below that. (What look like double quotes in the block below are actually consecutive single quotes.)
DECLARE
v_any_condition VARCHAR2(30) DEFAULT '4,9,d';
v_sql varchar2(2048);
rc sys_refcursor;
rc_record dual%ROWTYPE;
v_counter NUMBER DEFAULT 0;
BEGIN
v_sql := '
SELECT token
FROM (
WITH t AS (SELECT ''0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f'' AS txt FROM DUAL)
-- then decompose the list into rows
SELECT REGEXP_SUBSTR (txt, ''[^,]+'', 1, LEVEL) AS token
FROM t
CONNECT BY LEVEL <= LENGTH(REGEXP_REPLACE(txt,''[^,]*''))+1
, TABLE(CAST(XX_SPLIT_STRING(:a,'','') AS XX_SPLIT_TABLE)) cst
WHERE cst.column_value = token'
OPEN rc FOR v_sql USING v_any_condition;
LOOP
v_counter := v_counter + 1;
FETCH rc INTO rc_record;
EXIT WHEN rc%NOTFOUND;
DBMS_OUTPUT.PUT_LINE (v_counter || ': '||rc_record.dummy);
END LOOP;
END;
-- And the main SQL, just for clarity:
SELECT token
FROM (
WITH t AS (SELECT '0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f' AS txt FROM DUAL)
SELECT REGEXP_SUBSTR (txt, '[^,]+', 1, LEVEL) AS token
FROM t
CONNECT BY LEVEL <= LENGTH(REGEXP_REPLACE(txt,'[^,]*'))+1
, TABLE(CAST(XX_SPLIT_STRING('4,9,d',',') AS XX_SPLIT_TABLE)) cst
WHERE cst.column_value = token;

How to refer field of DataSource in transfer rule for DSO object in BI 7.0

hello Gurus,
I am new to BI 7.
pls tellme how to refer field of DataSource in transfer rule for DSO object.
I will assign points to proper answer.
Praveen.

hi praveen,
when u create the transformation for the DSO, it asks for the source. in that you enter your datasource, then you get the datasource fields on one side and the rules in the middle and the DSO objects on the other side. whichever field of DataSource you want to refer in tranformation rule, just connect that field to the rule for the required object of the DSO.
hope this will help you.

Am working in creating a cluster environment. For my testing i created a new managed server(OSB_Server) in 9001 port in the admin console itself and that server started running. The default managed server(Admin_Server) is in 7001 port. So when i deploy a code in 7001 sb console the WSDL gets exposed in 7001 because the default admin server port is 7001. While deploying a code in service bus admin console we are not specifying the target name. So how to specify the target name while deploying the code in service bus admin console. Plz help me.

Hi Prabhu,
There are three kind of server architecture possible for OSB -
1. Single server - Everything gets deployed on Admin server itself
2. Admin Server + Single Managed Server for OSB -- OSB configuration gets deployed on OSB managed server. OSB resources (proxy service, WSDL, Schema) will remain available on OSB managed server port only and NOT on admin server port
3. Admin Server + OSB cluster -- OSB configuration gets deployed on OSB cluster. OSB resources (proxy service, WSDL, Schema) will remain available on OSB Cluster port(s) only and NOT on admin server port
Converting one type of server architecture to any other type, requires a manual tedious process, so it is suggested that you create domain accordingly i.e. if you need clusters then while creating domain itself, create OSB cluster, so that all OSB applications gets deployed to OSB cluster. I will suggest you to create a clustered domain from scratch and import the configuration from your existing domian to this new clustered domain.
