Using SSO to connect to database from J2EE

I have an SSO enabled J2EE application and an SSO enabled database and I can connect to both of these applicatins using the single sign-on account.
What I want to know is
How do you get a J2EE application to connect to the database with the already connected SSO credentials?
I am using Oracle 10g for both the app server and database
Any help will be gratefully received.

Hello,
Also we have a simple how-to about database proxy authentication in the OC4J 10.1.3 How-tos page (see How-To Configure and Use Proxy-authentication with Data Sources ).

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
<b>I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?</b>
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

Not able to connect RAC database from client

Recently I have configured RAC in test environment. version 11.2.0.1. OS Redhat 5.9. Everything seems to be fine except not able to connect rac database from client. Error is as under :

This error means that the hostname or IP address used in the TNS connection string, failed to resolve or connect.
Your client is making two connections. The first connection is to the SCAN listener. It matches a db instance for your connection request based on service requested, available registered service handlers, load balancing, and so on. It then send a redirect to your client informing it of the handler for that service.
Your client then does a second connection to this service (a local RAC listener that will provide you with a connection to the local RAC instance). This is what seems to be failing in your case.
The SCAN listener's redirect uses the hostname of the server that the local listener is running on. Your client needs to resolve that hostname (of a RAC node) to an IP address. This likely fails.
You can add the RAC node hostnames to your client platforms hosts file. The appropriate action however would be to ensure that DNS is used for name resolution instead.

How to connect oracle database from tuxedo

Hi,
How to connect oracle database from tuxedo.
If any one can help me.
Regards,

it depends on configuration your going to choose, there are two ways--
- Using X/Open standards, for this
you have to make an entry of Resource manager in $TUXDIR/udataobj/RM file.
Then in UBBConfig file in GROUPS section u have to set Openinfo.
It also depend on which database you are going to use.
In your service now you need to call tpopen() API from tpsvrinit() function.
- Other possibility is, take an implicit connection using Pro*C or Pro*Cobol whatever platform you are using.

When connect the Database from Toad , Sqlplus giving the error

when connect the Database from Toad , Sqlplus giving the error

Thanks & Regards,

when connect the Database from Toad , Sqlplus giving the error recent changes 12.1.1 installatiojnHave you tried using the same user via simple sqlplus on the database server or apps tier server itself? Please try the same database user/login on the database server using the sqlplus available on the server itself. See what message do you get. If the the login happens, then try with the tns entry e.g. sqlplus username/password@prod and see if that works on the db server. If both of these conditions work the check where is Toad picking up the tns entry from on the client pc/laptop. If first test fails, then check if the account is locked.
Hope this helps.

Getting exception ORA-12705 while trying to connect to database from forms 9i

Hello All,
I have installed 9i database and I gave path for oracle home as Oracle_path while installing. then I installed 9i dev suite, Installer forced me to use different Oracle home, so I gave Odev_path as path.
I have created server alias name from dev suite to Oracle database and I could connect to database from froms 9i. suddenly it started giving me the following exception when I try to connect database from forms 9i.
ORA-12705 invalid or unknown NLS parameter value specified
could some one help toresolve the issue.
Thanks in advance

I have already seen this document and tried it out, but it didn't work. And I have tried out numerous other tips that I have found in different places on the web.
Is the client installation of any relevance? I notice that this user has a different installation from the one that I have, and that he amongst other things doesn't have sql plus installed.

Error connecting to database from Crystal Report

Hi,
I am using Crystal report 2008, .NET 3.5 on Windows Server 2008 + SQL Server 2008
I have a batch that generates report (via export) then this batch will send the exported report via email.
I am encountering this error when reading report from BO Server

The report is working in our SIT environment but it is not working in our UAT environment.
I have tried the following:
1) running the batch (that generates the report) in SIT environment to call SIT database
Working fine
2) running the batch (that generates the report) in SIT environment to call UAT database
Will give the above error
3) running the batch (that generates the report) in UAT environment to call UAT database
Will give the above error
4) running the batch (that generates the report) in UAT environment to call SIT database
Working fine
For reading report from BO Server, I have tried viewing the report directly and scheduling the report directly from BO Server and it works fine.
Also I have tried to 'verify database' on the UAT report, but it seems it didn't solve the issue.
Does anyone have any idea how to solve this? Or what could cause this?
Appreciate your help.
Thanks.

            'Create a session manager
            Dim sessionMgr As New CrystalDecisions.Enterprise.SessionMgr
            'Log into BusinessObjects Enterprise
            enterpriseSession = sessionMgr.Logon(cu.BOXIUser, cu.BOXIPwd, cu.BOXIServer, cu.BOXIAuthentication)
            'Create the infostore object
            enterpriseService = enterpriseSession.GetService("InfoStore")
            infoStore = New CrystalDecisions.Enterprise.InfoStore(enterpriseService)

                CrDiskFileDestinationOptions.DiskFileName = reportFile
                CrExportOptions = crDoc.ExportOptions
                With CrExportOptions
                    .ExportDestinationType = ExportDestinationType.DiskFile

            End If
The error is thrown when trying to export --> crDoc.Export()
The username and password are correct because it is the same username and password that the batch used to extract the data in the initial stage.
Here's how my batch works:
1) Extract and massage data directly from .net SP (this is working fine)
2) Obtain the report then use the same connection string (for physical path report) or use the report connection string (for bo server report), this report is using Stored Procedure (the problem starts here)
For reading report from bo server, I have also checked that the connection from the report itself is correct, because we can schedule/view the report from bo server successfully.
SQL Driver, is it the SQL Native Client you are saying? It's SQL Native Client 10.
I think we are using Business Objects Enterprise XI 3.1 Client Tools SP2 in our apps server.

How to use JDBC to connect informix database

Dear all,
I want my client application to connect informix database by using JDBC. The JDBC driver has been installed successfully in the client computer (Win2000). The informix 5.0 resides the a Unix server named "dbserver". The following is my java program.
========================
import java.sql.*;
import java.awt.event.*;
public class Application1 {
public static void main(String[] args) {
Connection conn;
try
Class.forName("com.informix.jdbc.IfxDriver");
catch (Exception e)
System.out.println("Error "+e.getmessage());
e.printStackTrace();
return;
System.out.println("It is ok");
try
conn = DriverManager.getConnection("jdbc:informix-sqli://dbserver:1526:INFORMIXSERVER=dbserver;username=test;password=******");
catch (SQLException e)
System.out.println("ERROR ."+e.getMessage());
e.printStackTrace();
return;
System.out.println("All is fine");
===========================
However, the error appears mentioning "Attempt to connect to database server (dbserver) failed." I don't know what the problem is because my informix database server is exactly "dbserver".
Kindly need help from you guys. Thanks in advance.

Hi,
Plz try this (instead of 'username' use 'user') ...
DriverManager.getConnection("jdbc:informix-sqli://dbserer:1526:INFORMIXSERVER=dbserver;user=test;password=*****");
or this (pass the username and password as params)....
DriverManager.getConnection( "jdbc:informix-sqli://dbserer:1526:INFORMIXSERVER=dbserver" , "test" , "*****" );
Hope this helps

Hi Nitin
Thanks for the helpful! With your point I'm now Pro! Great thanks.
By the way have your seen that?
Files such as LISTENER.ORA, TNSNAMES.ORA, SQLNET.ORA, if configured manually, or copied and edited from earlier releases of Oracle Database may have record attributes that are incompatible with Oracle Database 10g release 2. The software cannot read such files. The required record format is stream_lf and the record attributes are carriage_control and carriage_return.
This may result in:
Inability to start the listener
Services not registered with the listener
Inability to connect to other databases
ORA-12154: TNS:could not resolve service name
Run the following command on each file affected:
$ DIR/FULL filename
An output similar to the following may be displayed:
Record format: Variable length, maximum 255 bytes
Record attributes: Carriage return carriage control
If the output includes the preceding entries, then run the following command:
$ CONVERT/FDL=SYS$INPUT filename filename
RECORD
CARRIAGE_CONTROL CARRIAGE_RETURN
FORMAT STREAM_LF
^Z
Otherwise herewith an interesting metalink note. Doc ID: Note:437597.1

Hope this will also help you...

I have developed an application using ASP and MS-SQL7.
Now i want to port this application to Oracle 8i database
I have written my connection in seperate file called
connection.inc using SQL OLEDB provider
If i have to connect oracle database what will be my provider
and what is the exact code for this connection string
Here i am giving the code of SQL databse connection string
strcon= Provider=SQLOLEDB.1;Persist Security Info=False;User
ID=sa;Initial Catalog=prjdb;Data Source=servername
i have tried by changing the provider name from SQLOLEDB.1 to
OraOLEDB.oracle
but i could not able connect the database.
It is giving provider not found or not properly installed error.
But the same code is perfectly working from Visual Basic code.

it depends on configuration your going to choose, there are two ways--
- Using X/Open standards, for this
you have to make an entry of Resource manager in $TUXDIR/udataobj/RM file.
Then in UBBConfig file in GROUPS section u have to set Openinfo.
