JDBC/ODBC Connections using 9iDS?

I've just installed 9iDS and I noticed that there is no OCA installed. Has anyone with 9iDS tried using JDBC/ODBC to connect to a non-Oracle database?

Correct we are no longer shipping the OCA - You should be looking at the Oracle gateways as a way of providing non-oracle access for Forms and Reports.

You can't plug ODBC or JDBC into Forms as an alternative to SQL*Net (unless you want to do a lot of 3gl coding and Transactional triggers)

Problem in building JDBC ODBC connection with my stand alone Project.

Hello Everyone!
I gave the following command in order to create JAR file:
C:\app>jar cvfm MyJar.jar Manifest.txt .
and the Manifest file contains the code: Main - Class: Login
My Manifest File and the .class codes and the JAR file which is created successfully by the above command are in the same folder "app" and then I run the project both at command prompt by the command : C:\app>java -jar MyJar.jar
and by double clicking the JAR file. My project is running successfully but, I am using JDBC - ODBC Driver in my project and I want to let this project run in any other computer system. So, any other user who is unknown to the Driver used and Database used in my project can't be able to run my project if the specified driver is not installed in his machine and also there is a bridge of ODBC Data Source (from control panel-- Administrative Tools-- Data Sources(ODBC) )from which Driver is selected and the Database is specified.
In order to test my application, I had removed the data source name from the Control Panel's Data Sources (ODBC) properties' window. Then I run my project then the following error msg is shown in command prompt:
C:\app>java -jar MyJar.jar
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6879)

at Login.<init>(Login.java:37)
at Login.main(Login.java:364)
Error Trace in getConnection() : [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
So, I have a doubt at this point that how a user is able to configure this bridge in order to run my application who is unknown to my project's back-hand? As JRE is essential to run my project so, I have decided to give setup of JRE with my project's CD, may the JDBC - ODBC Driver providing to the user with my application setup solve this problem ?
Please help me to solve my problem.

Please please help me.Lets presume hypothetically that the jTDS driver won't work with 2000. It might or might not.
However the fact remains that your ODBC driver is not working.
So the first step is to stop trying to run your full application. Instead you create a very simple console application that does nothing but connect to the database.
Problems that usually occur from that would be.
1. The connection string is not correct for MS SQL Server.
2. The connection information for the database is not correct
3. The database (nothing to do with java) is not configured to accept connections.

JDBC-ODBC connectivity from JSP page

hi
i am trying to connect a jsp page with database using jdbc-odbc driver. i have created a dsn with the name 'test' that connects to a database 'test' in SQL server. the following lines has been added to the web.xml file placed in the \WEB-INF folder
<context-param>
<param-name>
javax.servlet.jsp.jstl.sql.dataSource
</param-name>
<param-value>
jdbc:odbc:text, sun.jdbc.odbc.JdbcOdbcDriver
</context-param>
i have also placed the rt.jar file in the \WEB-INF\lib folder. but, when i run the jsp page and ty to make any database interaction, an expection occurs
java.lang.ClassNotFoundException : sun.jdbc.odbc.JdbcOdbcDriver
please help

I think you need to download the JDBC/ODBC driver jar file into your project. For example, if you need a JDBC driver for the Oracle database, you search google for 'oracle jdbc driver'. Its driver is something like classes14.jar. I suggest you create and test your database connection pool in a servlet so you will have an easier time debugging any issues in getting it to work.
Also, as the previous post points out, JSP is for displaying data and submitting user input back to the servlet. Put all your business logic in the servlet, put any data you get from the database in request scope by the servlet, dispatch to the JSP page so it can be displayed. This is a crude example. For a better design read up on MVC (Model View Controller) design.

Jdbc-odbc connectivity problem in[b] wsad5.1.2[/b]

while i Try to access the msaccess database using sun.jdbc.odbc.JdbcOdbcDriver,the server is giving the error class not found....sun.jdbc.odbc.JdbcOdbcDriver......
I have already rt.jar containing this class in my jre...
The same thing i tried in wsad5.0 and it is working abs fine....
If anyone has got a time to solve tis query plz help me out...
Its urgent......

well,i think nobody has interest in my question.I have asked two questions.
1)Can anybody tell me the compatibilities of JDBC-ODBC bridge versions,oracle and ODBC drivers?
2)And can u tell me how to connect to oracle through a pure Java JDBC drivers (type 4 drivers) on a standalone system?
But u advise me not to use JDBC-ODBC bridge without studying the other part.

Problem with JDBC ODBC connectivity

I am trying to connect to MS access database with jsp page. This is sample from my js page :
String SUN_DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(SUN_DRIVER);
String aDataSourceName = "puneet";
String url = "jdbc:odbc:" + aDataSourceName;
Connection con;
con = DriverManager.getConnection("jdbc:odbc:puneet","","");
The last line gives me the follwoing error :
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
puneet is name of my datasource and it points to my .mbd file.
I dont have anyusername or passwords for this daatsource.
I am using Tomcat/4.1.18-LE and jdk1.4
I have also added rt.jar in the classpath
pls help
pg4

Hi pg4,
May be your dsn is not pointing to .mdb file. Check it by putting your mdb file right where your code is and then user following syntax which is called dsn-less connection. It helps you to connect to the target mdb file with out any need of dsn.
String url = "jdbc:odbc:;Driver={Microsoft Access Driver (*.mdb)}; DBQ=yourDBFile.mdb";

Humayun

How to use jdbc:odbc without using ODBC applet in Control Panel??

Hi All,
I have a servlet that interacts with an MS Access database called test.mdb, I'm connecting to it using DSN which is test
conn = DriverManager.getConnection("jdbc:odbc:test", "", "");
However I want to upload the servlet along with the database to a remote server, how can I change the code to point the database name test.mdb without -obviously- using the DSN name that is set in the control panel
Thanks in advance

smg123 Thanx a lot.
I'm using Access because the remote server has only Access now
Thansks for the advice appreciate it.

but the bug haven't been fixed ?Could be. But if so it is in a newer version of the odbc driver than the one you have. (Again this has nothing to do with java.)
The odbc applet in windows allows you to inspect the version number. Depending on your business environment you might be able to find and use a different one. It might be possible to download a newer version from somewhere.
As I stated another driver (jdbc) is likely to fix the problem as well. Which database are you using?

JDBC-ODBC Connection

Both my office and home computers are installed with Win 2000, Java 2 SDK SE 1.4.1_01, and Tomcat 4.1. Then how come I can connect to the database and run JSP with the office computer, but I can't even connect to the database with the home computer? I tried the JDBC:ODBC:(ODBC Name here) and the home computer pops up an "unidentified error" message.
* How can I check if my computer is installed with the JDBC-ODBC bridge driver?
* Is there a serarate download file for that? I understand it automatically comes with Java 2 SDK, but I don't see how it's working. I uninstalled and reinstalled Java 2 SDK many times, but all the same.
* Is there any other way to connect to the database and run JSP without using the JDBC:ODBC thing?
Y.C.

Using MS Access. Both my office and home computers are running with ASP on IIS and ColdFusion on ColdFusion server. I connect to either MS Access or MS SQL. I've tested ODBC and know it's working though I usually connect through OLEDB. As you may have already guessed, I am new to JSP. My big question at this moment is why JSP to MS Access through ODBC is working in my office but not at home when both computers are almost clone to each other in the same working environment. What else would be the factor in difference than those I told in my previous message?
This is a part of the connection coding that worked in the office but not at home:
String MM_connCareerSE_access_DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
String MM_connCareerSE_access_USERNAME = "";
String MM_connCareerSE_access_PASSWORD = "";
String MM_connCareerSE_access_STRING = "jdbc:odbc:CareerSE";
What other information would you need?
By the way, how do you connect to MS SQL with JSP?
Y.C.

Automatic jdbc odbc connection

we have an application that uses an access database. normally we have to go to control panel, go to the DataSources and manually setup the odbc connection. after this, our program connects to the database and works as planned. what we want to do is to automatically connect the database, like having an executable file that automatically installs a software. is there any way that would connect the database to the computer without manually performing all those tasks?

Use some other jdbc driver than jdbc-odbc driver. to find the driver list visit

String url="jdbc:odbc:test";
Connection connection=DriverManager.getConnection(url,"","");
Statement stmt= connection.createStatement();
stmt.executeUpdate("INSERT INTO member " +
"VALUES ('zben','curepipe','mru')");
// Close the database
connection.close();
}catch(Exception ex){
message.setText(ex.toString());

Serious problem of jdbc-mysql connectivity using tomcat

hi everybody
i m in serious problem since last 15-20 days. i m trying hard to make the connection jdbc-mysql using tomcat with the help of a jsp test page but every time i am facing almost the similar probems listed below in detail:
to make sure that the jdrivers's .jar (mysql-connector-java-3.1.7-bin.jar) available for such connections working fine i have tried the above said connection without using tomcat....which is working fine...for this i have created a dummy database with a dummy table ..and written some queries in the .java file of my code which upon running inserts the specified values in the defined(dummy) database.
this is the confirmation that the classpath etc..are ok in regard to the mysql-connector-java-3.1.7-bin.jar
now i have placed a copy of this .jar file in to the commons/lib directory of the tomcat web server(which is suppossed to be the place for such external jars)
after doing so i have followed 2 methods :
method 1st:........
i have made aone more jar file from the following .java file....
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class TestSQLLoad
String user = "Not Connected";
String pwd = "no pwd";
int id = -1;
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null ) {
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if (ds != null) {
Connection conn = ds.getConnection();
if(conn != null) {
user = "Got Connection "+conn.toString();
Statement stmt = conn.createStatement();
String q = "select name, password, id from user";
ResultSet rst = stmt.executeQuery(q);
if(rst.next()) {
user=rst.getString(1);
pwd=rst.getString(2);
id = rst.getInt(3);
conn.close();
}catch(Exception e) {
e.printStackTrace();
public String getUser() {
return user;
public String getPassword() {
return pwd;
public int getID()
return id;
after compiling it at the cmd prompt i made a .jar file from the .class of it and named it MySQLLoad.jar...then i placed it also in to the commons/lib directory where the mysql-connector-java-3.1.7-bin.jar was already placed.
then i have changed the server.xml and web.xml files from the conf directory of the tomcat as given here:

</web-app>
after all this i have taken a jsp page whose code is here:
(the mysql database used is named as "testdb" and the table name is "user" which is having fields name,password and id)
<html>
<head>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
and placed it in to the Tomcat 5.5\webapps\tomcat-docs\testdb directory and saved as test-db.jsp
when i run this page on the browser i get a lot may errors stating
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /testdb/test-db.jsp
Generated servlet error:

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
note The full stack trace of the root cause is available in the Apache Tomcat/5.5.4 logs.
AND NOW WHEN just to get rid of such errords i try to include a statement
<%@ page import="pkg.TestSQLLoad" %> in the jsp page code (and also place the MySQLLoad.class file in a folder called pkg and place it in the same directory where the jsp page is )and make it look like
<html>
<head>
<%@ page import="pkg.TestSQLLoad" %>
<title>DB Test</title>
</head>
<body>
<%
TestSQLLoad tst = new TestSQLLoad ( );
tst.init();
%>
<h2>Results</h2>
User <%= tst.getUser() %>
Pwd <%= tst.getPassword() %>
Id <%= tst.getID() %>
</body>
</html>
now when i run it i get the following errors:
exception

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
in response to the above error i have even tried placing the MySQLLoad.class directly in the testdb folder along with the jsp page without keeping it in a package named pkg and then importing directly as <@page import="MySQLLoad" %>
that too gave me the following errors

and if i do not use the statement <%@ page import="MySQLLoad"%> then also i get the errors like

THE 2nd Method:
in my second method i did the same changes in the web.xml and server.xml
then i took a jsp page with the following code:
<%@ page import="javax.sql.*,java.sql.*,javax.naming.*,com.mysql.jdbc.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> trial doc </TITLE>

<% InitialContext context=new InitialContext( );
DataSource dataSource=(DataSource) context.lookup("java:comp/env/jdbc/testdb");
Connection conn=dataSource.getConnection();
Statement stmt=conn.createStatement();
ResultSet rset=stmt.executeQuery("select * from user");
if (rset.next()){
%>
<table width="100%" border="1">

</tr>
<%
do {

CR 2008 and ODBC connection using Oracle Instant Client driver?

Two questions.
I'm creating CR 2008 report using an ODBC connection. The ODBC driver is the Oracle Instant Client (version 10.2, I think.)
When I define the connection, I see only a few tables. I do not see the Tables, Views, Qualifiers tree that I see with a normal Oracle Server connection.
Does anybody know why this happens? Is there a CR ODBC driver that works better?
Second question: I have a .NET application that is pointing the report to another Oracle DB. In my db, table names are not unique -- each user has the same set of tables. I find that when the .net applciation sets the datasource, I get connected to the first table with a given name; I do not get the table scoped by the logon user.
In the .net application, how do I scope the table name to a particular user.
Any info helps. Thanks.
Tim

Hi Tim,
Below are the replies to your questions:
Answer 1: Please try the below steps:
- Make sure that in File->Options->Database Tab in the Data Explorer section the corresponding checkboxes are checked for tables, views,system tables,synonyms and stored procedures and the Table name LIKE and Owner LIKE boxes are blank.
- Please try with OLEDB connection and check the results.
- You can also refer to this SAP note no# 1215994, the link to which is given below:
[https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/sno/ui_entry/entry.htm?param=69765F6D6F64653D3030312669765F7361706E6F7465735F6E756D6265723D3132313539393426]
Answer 2: If you are using RAS SDK only then you would be able to change table name. Please let us know if you are using RAS.
If you are using RAS with Java please post your query in the Java forum else if you are using Visual Studio/.NET then please post your question in .NET Forum.
Please update with the results.
Thanks!

Jdbc odbc connectivity issue

I have made one system dsn ...in some folder..then in my jsp page my
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection myConn = DriverManager.getConnection."jdbc:odbc:Employee");im getting error like no data source...and its finding in root directory like c:/document seting etc etc ..not where my db lies
if i put my db in root directory .then code wrks fine..but is it taking that root directory

well well the code would not consider nothing here the microsoft native bridge driver has to find appropriate database.
Are you sure u have created an entry in Odbc Data Source Administrator --> System DSN -> and you have a name called "Employee" out their pointing to appropriate database which you are trying to connect.

JDBC Thick connection using ADF

Hi All,
I am doing Thick Oracle connection using ADF but i am getting this error...
java.lang.UnsatisfiedLinkError: no ocijdbc11 in java.library.path
following is my code..
try {
Class.forName("oracle.jdbc.OracleDriver");
Connection con=DriverManager.getConnection("jdbc:oracle:oci8:@dbndevp", "mfonline", "mfonline");
System.out.println(con.isValid(1));
} catch (Exception e) {
e.printStackTrace();
So how can i do it in ADF......
-Thanks

Suppose i have a backing bean class then how would i get connection to database, Suppose that i am using 2 connections to 2 different database.Case 1: If you are using ADF Business Components (or some other framework that implements "business services" layer)
In this case ADF BC implement the "business services" layer in the application architecture and they are responsible for the interaction with the DB. You should encapsulate there all the program logic that interacts directly with the DB. You can invoke ADF BC methods from managed beans but you should not implement any direct DB operations in managed beans (in particular you should not open DB connections, parse and execute SQL statements in managed beans). If you need to work with 2 different databases, then you have to define 2 different ApplicationModules (with connections to these databases). There is an important disadvantage - ADF BC does not support global transactions (e.g. XA-compatible transactions), so if you need distrubuted transactions, then either you could use DB-links (if both databases are Oracle ones) or you will need a different framework.
Case 2: If you are not using any framework that implements "business services" layer
In this case you should not use DriverManager, but you could get DB connections from JDBC DataSources. In this way you would benefit from the connection pooling of the DataSources and you would avoid the heavy overhead of creating and closing DB connections. (When you close a DB connection acquired from a DataSource, in fact it is not closed but it is just checked back into the DataSource's connection pool).
