Connect via Oracle JDBC driver from CDC: is it really impossible?

Hi everyone.
I try to connect to usual (non-Lite) Oracle database from CDC-driven Java application.
The obvious problem is the absence of JNDI implementation in CDC profile (OracleDataSource implements javax.naming.Referenceable, so this problem is critical).
Is there any possibility to establish direct connection to Oracle, without any intermediate tier?
Best regards.

Pardon my ignorance, but what is a "CDC-driven Java application"? In Oracle, CDC generally refers to Change Data Capture, but I'm imagining that's not what you're talking about here...

Calling Oracle JDBC Driver from JSP

I have Apache Tomcat installed under Win2000 and can run simple JSP
pages without any problems. I have installed Personal Oracle 9.0.1.0.1 on my win2000 PC and I can login using sqlplus as scott/tiger. The database is up.
But when I try to access an Personal Oracle DB from a JSP page I get the following
exception:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
root cause
java.sql.SQLException: Io exception: Bad packet type
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:180)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:222)
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Here is my JSP program:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@page language="java" import="java.sql.*"%>
<%
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@<my host PC name>:8080:shark","scott","tiger");
Statement stmt = conn.createStatement ();
stmt.close();
// Close the connection
conn.close();
%>
Does anyone know why this error is showing up?
Thanks

Problem has been resolved. I did not have the Personal Oracle DB Listener running and the port needed to be changed to 1521 on the JSP program.

Installing JDBC driver to connect to Oracle 8i Database from Weblogic 10.3

I want to connect to Oracle 8i database from weblogic 10.3 application server. I found a classes12. zip file on Oracle.com to use as driver for the same.
I am also connecting Oracle 9i database from the app server. Now if i replace the classes12. jar from the lib folder won't it disallow me to connect to the Oracle 9i database.
2ndly the claases12.zip file i found from the site is for jdk 1.2 will it create any problems. Please let me know
Kindly let me know what is the standard procedure to install a new driver in Weblogic 10.3.

I tried to install weblogic 10.3 using jdk 1.5.07 but. it is not supported. Moreover from the sites also i found that it's only the application wars and ears compiled in jdk 1.5 need not be recompiled in 1.6. But no reference of jdk 1.5 is there.
I tried to use thin client from the code and connect to Oracle 7i
i got the following exception.

What is the exact 10g version?
According to MOS note 207303.1, for connection between 11g client and 10g server, there is a minimum version requirement on 10g server side.

Load oracle jdbc driver error when run applet via the web

Hi All,
I have built an applet which connect to database via jdbc thin driver. It works fine when I run it through the applet viewer, but got a problem when run it through the web.
java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
I am using jdev9i 9.0.4 and jdk 1.4.2. The jdbc version is 9.0.1
I have added both the classes12.zip and ojdbc14.zip in the class path and also pack them together with my applet class. Here is the code
public class MyApplet extends Applet
implements Runnable
public void start()
if(theThread == null)
theThread = new Thread(this);
theThread.start();
Retrieve R = new Retrieve();
this.MyMap = R.retrieveDesc();
public class Retrieve
public Retrieve()
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@babyruth.wvu.edu:1703:devdw", User, Password);
conn.setAutoCommit(true);
connectStatus = true;
public HashMap retrieveDesc()
return map;
I have also built one HTML page NewApplet like this
<HTML>
<HEAD>
<TITLE> My New Applet</TITLE>
</HEAD>
<APPLET CODE="MyApplet.class" CODEBASE="menu" ARCHIVE="MyApplet.zip" WIDTH=300 HEIGHT=485>

<param name="bgcolor" value="255,255,255">
</HTML>
Any advice is highly appreciated
Mei

Sir,
Well you haven't "packed" them correctly. Why don't you just add the driver bits to the soucebase tag? or something like that anyway...
Sincerely,
Slappy

NullPointerException at oracle.jdbc.driver.OracleDriver.connect()

I have written a java stored procedure. The method can be executed properly in local PC environment.
but when the java program is load into Oracle DB JVM by loadjava command. such method is called in SQL> prompt as a java stored procedure. I got
java.lang.NullPointerException
at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:379)
at java.sql.DriverManager.getConnection(DriverManager.java:573)
at java.sql.DriverManager.getConnection(DriverManager.java:187)
at WCZSynchronizer.testLocalConn(WCZSynchronizer:901)
as shown in the trace file.
The line in my own java program WCZSynchronizer is simply
Connection conn = java.sql.DriverManager.getConnection(db_connection_string,username,password);
I am sure that the db_connection_string, username and password are correct as it works in my local PC.
I even try to get default connection by
Connection conn = java.sql.DriverManager.getConnection("jdbc:default:connection:");
and
Connection conn = new oracle.jdbc.driver.OracleDriver().defaultConnection();
I got the same NullPointerException in both cases too.
In fact, the java stored procedure worked before. but suddenly it's failed! The Oracle DB server is under my control and I did not change any configuration nor setting on it.
I can't find similar case from this forum. Do any one know why?
thanks.

First try debugging the test case by making sure that none of the parameters passed to getConnection is null.
When you are sure that none of the parameters are null, if the issue still reproduces. Let us know
- The driver version
- The jar file you are using
cheers

Cannot connect using oracle jdbc oci8 driver

I am using Oracle 8.1.5 JDBC oci8 driver, but when try to connect, always got ERROR: java.lang.UnsatisfiedLinkError:make_c_state
With the same code, but change to connect with thin driver, it works fine. Pls tell me the problem. Thank you.

Hi,
Here is the snippet code from oracle,
// You need to import the java.sql package to use JDBC
import java.sql.*;
// We import java.io to be able to read from the command line
import java.io.*;
class JdbcCheckup
public static void main (String args [])
throws SQLException, IOException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Prompt the user for connect information
System.out.println ("Please enter information to test connection to the database");
String user;
String password;
String database;
user = readEntry ("user: ");
int slash_index = user.indexOf ('/');
if (slash_index != -1)
password = user.substring (slash_index + 1);
user = user.substring (0, slash_index);
else
password = readEntry ("password: ");
database = readEntry ("database (a TNSNAME entry): ");
System.out.print ("Connecting to the database...");
System.out.flush ();
System.out.println ("Connecting...");
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@" + database,
user, password);
System.out.println ("connected.");
// Create a statement
Statement stmt = conn.createStatement ();
// Do the SQL "Hello World" thing
ResultSet rset = stmt.executeQuery ("select 'Hello World' from dual");
while (rset.next ())
System.out.println (rset.getString (1));
System.out.println ("Your JDBC installation is correct.");
// close the resultSet
rset.close();
// Close the statement
stmt.close();
// Close the connection
conn.close();
// Utility function to read a line from standard input
static String readEntry (String prompt)
try
StringBuffer buffer = new StringBuffer ();
System.out.print (prompt);
System.out.flush ();
int c = System.in.read ();
while (c != '\n' && c != -1)
buffer.append ((char)c);
c = System.in.read ();
return buffer.toString ().trim ();
catch (IOException e)
return "";
This code can be run without specifying a TNSNAME connection string, as the oci8 jdbc driver will take localhost as default.
OR
Only specifying the TNSNAME is enough, i.e. edit %ORACLE_HOME%\network\ADMIN\TNSNAMES.ORA file and locate the XXXXX.WORLD entry in the file. This is the TNSNAME entry referred to.
Without TNSNAME entry you can re-run,
%ORACLE_HOME%\jdbc\demo\samples\oci8\basic-samples> java JdbcCheckup
Please enter information to test connection to the database
user: system
password: manager
database (a TNSNAME entry):
Connecting to the database...Connecting...
connected.
Hello World
Your JDBC installation is correct.
Hope that helps.
Best Luck!

Oracle jdbc driver spending 40 seconds to make connection to Oracle db 11g

we are using weblogic 10.3.3 and teh default Oracle11.1.0.7 Driver ojdbc6.jar to talk to Oracle db 11.2.0.1
After reviewing weblogic logs I see that it takes 50 secodns for each connection to db
HHere is a snippet (note I put in a 10 sec login dleay as i was experimenting, butt eh problem still occurs with or without login delay)

<Dec 21, 2010 1:29:09 AM GMT> <Info> <JDBC> <BEA-001068> <Connection for pool "acm_repository" created.>
There is someting wrong in this environment
I donwloaded the _g version fo teh exact same driver and had weblogic use it so I could generate verbose logs
Here is a snippet fo teh oracle drivers verbose log file . If you notice the key parts
it seems like its spending 40 second to make the connection, goes into a setConnectionDuringExceptionHandling method and creates the connection
can someone shed light on what causes itto go into an exception state
This happens for each and every connection but only in one specific environment
we have other environments which seem towork fine with the exact same product versions except for this environment
Thank you for any guidance on troubleshooting this further

I would file an oracle jdbc bug to begin with, but I am guessing the driver is simply waiting
for the DBMS to respond, so yo may need a good DBA to see what the DBMS thinks is going
on at the time. I did hear of a case where the DBMS was doing some auditing, logging
some info during every login. This info was being written to an OS file which just happened
to be remote-mounted and would occasionally take 30 seconds, which caused connection
requests to timeout at the driver end.... WebLogic is just asking the driver for a connection
using your properties, so it's not involved directly with the problem....

Receiving oracle.jdbc.driver error when trying to connect

Setup:
Windows 7 64bit
4GB ram
SQL Developer 3.2.20.09
Java platform 1.6.0_37
Oracle IDE 3.2.20.09.87
Hello, I'm going to start by saying I'm a rank amateur when it comes to using and understand SQL developer. My entire need for this program is to connect to a virt server at my office and test out my SQL queries against our tables. It's been working great for this purpose until yesterday when I received this error:
An error was encountered performing the requested operation:
oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()I
Vendor code 0
I did some searching and found a few references to this error but due to my inexperience I was unable to follow the resolutions and fix the error. This connection was working fine until yesterday afternoon which seemed odd. Based on my control panel, here is what I installed yesterday, I believe I installed both Java's after the error occurred seeing if they would alleviate the issue.
MySQL Administrator 1.1
Java SE Development Kit 6 Update 41 (64-bit)
MySQL Workbench 5.2 CE
Java 6 Update 41 (64-bit)
Could one of these be the root of the issue?
Thanks for the help and sorry for the lack of technical expertise, my need is very narrow and up until now this program has worked great for me.

More likely to be that you are now using the wrong version of the oracle jdbc jar file.
Post the name and version of the JDBC jar file that you think you are using.
Search the pc for ALL such files.
Examine the environment variables (e.g. PATH) to see if they reference jdbc jars other than the ojdbc6 jar you should be using.

Jdbc connection using oracle thin driver( using jdk1.4 and oracle8 )

hello ..
while i was tring to connection using oracle thin driver and jdk1.4 am getting the below error message. i have set the class path for the driver also. am using oracle8 personal edition and jdk1.4.

    // DriverManager.getConnection ("jdbc:odbc:datasource", "system", "manager");
    stmt = conn.createStatement ();
catch (SQLException e)
      e.printStackTrace();

The code itself is fine; the problem is with one of:
1) the connection URL
2) intermediate networking
3) the database itself
1) your connection URL is "jdbc:oracle:thin:@127.0.0.1:1521:orcl"
- is Oracle really running on the default port, 1521
- is the installation SID really "orcl"
2) lots of possibilities, but only a couple are likely
- is TCP/IP configured and running on your host
- is there a persoanl firewall rpduct running? perhaps it's blocking the connection
3) Is Oracle running?
Is the listener running?

I would suspect, strongly, that at least some of the ways that you can use the Oracle driver would require a url change as well.
Did you try connecting from the client machine? Either via sqlplus or that command line utility (whatever the name is) that comes with the client? If those doen't work then java won't either.

HELP!!! Cannot deploy J2EE application with Oracle JDBC driver...

Hi,
I am writing a J2EE application which (in theory, at least)
connects to an Oracle 9i database.
I have written a simple Java test app utilising only the
java.sql package classes (e.g. Connection, ResultSet) to directly
connect to the database. As long as the classes12.zip is in the
CLASSPATH it works fine.
Now I have written an Enterprise application (SessionBean,
Remote and Home interface and Client) which I am attempting to
deploy via deploytool.
If I include just the client jar and EJB jar in the application
it deploys okay but when I run the application (using runclient)
it produces the following error:
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
(It is nested within other error output but that is the core
issue).
However if I try to include the JAR libraries into the app
(classes12.jar and nls_charset.jar from $ORACLE_HOME/jdbc/lib),
then I get the following output from deploytool when I hit the
"deploy" (or "redeploy") button:
Deployment error: invalid entry compressed size
(expected 14411 but got 14580 bytes)
Can someone please tell me what is going on???
How can I deploy the J2EE application including the Oracle
JDBC Driver???
My only other option at the moment is to place all the function-
-ality in the client and not use the J2EE framework.
Any help is greatly appreciated.

OK Ben,
I admit I'm a bit confused. Let me see if I understand where you're
coming from.
You have written a J2EE application that includes a session bean,
correct? If so, your session bean needs to be deployed to an EJB
container. What container are you using? The Oracle 9i database
has an embedded EJB container which (theoretically) you can use.
However, as far as I know, Oracle recommends you use OC4J as the
EJB container. So again I ask, what EJB container are you using?
If, as you say, you are new to EJB, then I think you should
immediately start working wiht OC4J as your EJB container.
Did you look at the tutorial link I gave in my previous post? It
explains -- step by step -- how to create, deploy and run a J2EE
application using OC4J as the EJB container. It also has links to
introductory material for people without little knowledge of J2EE
and EJB.
I have 9iAS Enterprise Edition and 8.1.7.1.0 database server (and
OC4J) installed on my SUN machine. I cannot find any of the
utilities you mention -- "j2eeadmin","runclient" or "deploytool".
What Oracle software have you installed? What are the versions?
What platform are you using?
A J2EE application (according to the specification from SUN)
consists of modules. A module can either be a client module or an
EJB module. A client module can either be a java application client
or a web-based client (servlet or JSP). A J2EE application usually
contains one client module and one EJB module. A J2EE application
needs to be deployed to a J2EE container.
Hopefully the J2EE picture is becoming clearer. I think you need
to read some introductory material regarding J2EE if you intend
to become proficient at it.
I feel that you are under the impression that a J2EE application
is a glorified JDBC application. It isn't (as far as I'm aware).
Good Luck,
Avi.

Could not load 'oracle.jdbc.driver.OracleDriver
If this is a type-4 JDBC driver, it could occur if the JDBC

If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)

This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL

3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.

Most likely, the OCI libraries could not be loaded.
Before continuing down this path, is there any reason
why you want to use an OCI based Driver as opposed to the
all Java Oracle thin driver ?There is indeed a valid reason for my choice.
I am currently connecting to the Oracle "Rdb" 7.0 database (located on
VMS) - not Oracle Oracle.
The SQL Service software we're currently using is version 7.1. This
version works well with the OCI8 driver (when connecting to the
database from Windows NT). This version of SQL Service however does
NOT work for the THIN driver (unless we upgrade the SQL Service to
version 7.1.5.5 - which we're not prepared to do so because it is not
stable enough from our previous test/trials). SQLSRV Version 7.1.5.5
works for THIN driver but it will result in uncommitted
transactions/unresolved connection/stopping of listener issues and
there is a need to restart the service from time to time. Oracle has
since confirmed that this is a bug that they have yet to resolve...
So we have to stick to OCI8 (THICK) for the time being. I would really
appreciate it very much if you can tell me the various OCI libraries
that I need to load (in terms of WebLogic Server config file settings
etc..).
By the way I have already installed the Oracle 8 client software on
the NT server (where WebLogic Server is) and I have also set up the
relevant SID (using the Net8 Assistant) that points to the Oracle Rdb
database on the VMS. I have also tried using SQL*Plus to connect to
the database and I can connect properly to the database. But WebLogic
simply doesn't seem to load the software.
Help...

Can't connect to Oracle XE instance from Java web application

I'm a long-time Java developer but can't figure this out.
I've been pouring over the forum for over a week and can't
find the solution that will let me connect.
Hardware: Intel/Vista.
DB: Oracle Express 10G.
Application: Java web application (Jakarta Struts)
Application Server: Tomcat 5.5
I copied the latest JDBC driver from OTN into my app server's "/LIB" directory.
I get no driver errors. ("ojdbc14.JAR)"
I can connect locally from my TOAD client, using SYSTEM/PASSWORD/XE.
My listeners seem to be OK.
Depending on which connection string I use from my Java application,
I get one of two messages.
"ORA-01017: invalid username/password; logon denied"
OR
"Io exception: The Network Adapter could not establish the connection"
------------ lsnrctl status ---------------------------------------------------

------------ SOURCE CODE ------------------------------------------------------
OracleDataSource ods = new OracleDataSource();
ods.setURL(" jdbc:oracle:thin:@localhost");
conn = ods.getConnection("system", "password");
//ods.setURL("jdbc:oracle:thin:@rsosborn-PC:1521:XE");
//conn = ods.getConnection("system", "password");
String query = "select * from books;";
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(query);

Using the code you supplied I was able to reproduce your errors. I've adjusted it accordingly and can connect to one of my 10.2 test databases.
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.*;
class Conn {
public static void main (String args []) throws SQLException
    Connection conn = null;
    OracleDataSource ods = new OracleDataSource();
    // ods.setURL(" jdbc:oracle:thin:@localhost:1521:TEST");
    // conn = ods.getConnection("scott", "tiger");
    ods.setURL("jdbc:oracle:thin:@localhost:1521:TEST");
    conn = ods.getConnection("scott", "tiger");
    Statement stmt = conn.createStatement();
    ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
    while (rset.next())
        System.out.println (rset.getString(1));   // Print col 1
    stmt.close();
}There are several different ways to configure OracleDataSources:

So, hopefully it's just a mismatch config.

Connect via Oracle JDBC driver from CDC: is it really impossible?
