Installing Postgresql JDBC Driver WLS 8.1

Hi,
Can somebody explain how I install the JDBC Driver for postgresql? I have WLS
8.1.2 on Win XP. I think the solution would be to set the CLASSPATH to the appropriate
location. But how do I do this permanently?
Thanks,
Oliver

OliverHi. Read the startWeblogic script to see how it constructs the -classpath argument for
the weblogic JVM. You can either add the postgres classes to an environment variable
PRE_CLASSPATH, or edit the startup script etc.

How to install a JDBC driver?

Hello, everybody!
I'm new to Java and I'm trying to install a JDBC driver. So, I downloaded the JayBird,
a JDBC driver for Firebird, and now I don't know how to install the driver. I keep
getting this message from the compiler when I try to compile the example that comes
with the driver:
DriverExample.java:182: package org.firebirdsql.jdbc does not exist
d = new org.firebirdsql.jdbc.FBDriver ();
^
1 error
So, in the directory that has the example file (DriverExample.java) I created the
following directory structure:
C:\Example\org\firebirdsql\jdbc
and inside the jdbc directory I copied the driver files:
firebirdsql.jar
mini-concurrent.jar
jaas.jar
mini-j2ee.jar
log4j-core.jar
and I still keep getting the error from the compiler. I just would like to
know what I have to do to install this driver correctly for the compiler to
find its packages.
Below are the instructions the comes with the help to install JayBird, but I
think that I did everything and it still didn't work:
======================================================================
The classes from firebirdsql.jar must be in the classpath of the Java
application being compiled, or otherwise made available to your application.
The classes from the following packages must also be available:
mini-concurrent.jar
jaas.jar (included in jdk 1.4)
mini-j2ee.jar (now including JDBC classes)
log4j-core.jar (if you want logging available)
The firebirdsql-full.jar file has all of the needed files in one
archive for ease of use.
These archives are included in the binary package.
======================================================================
Please can someone help me?
Thank you...
Marcos

My file (DriverExample.java) is in the directory 'Example' and the driver files are in the directory 'Example\org\firebirdsql\jdbc'
That's what I did inside the directory 'Example'
javac -classpath org/firebirdsql/jdbc/firebirdsql.jar DriverExample.java
And that compiled ok.
Now how can I specify where the driver files are for the java.exe? Of course I tried:
java DriverExample
and it didn't work.

Help installing new JDBC driver on LINUX

Hello,
Today, I downloaded the new SQL Server 2005 JDBC Driver onto
my Linux Server. The path to the driver's .jar file is
/root/sqljdbc_1.0/enu/sqljdbc.jar. I placed that path in my CF
Adminstrator "Java and JVM" page's Class Path field. I restarted
the app server but each time I try to establish a dsn connection I
keep getting this error. (note: I have dsn's set up already to this
instance of SQL Server 2005 so the communicatio is there but I
would prefer to use this new driver)
Connection verification failed for data source: dsnTestDB
java.sql.SQLException: No suitable driver available for
dsnTestDB, please check the driver setting in resources file,
error: null
The root cause was that: java.sql.SQLException: No suitable
driver available for dsnTestDB please check the driver setting in
resources file, error: null
Any help would be greatly appreciated.
Thanks,

Houston, TX

Try placing the jar file in the
{cfmx-root}/runtime/servers/lib (create if not already there)
directory if you have the server install or the
{jrun-root}/servers/lib directory if you have the multiserver or
j2ee install on JRun. Restart the Coldfusion applicatioin server.

How do I install the jdbc driver for sql server 2005, in sql developer 4.0 ?

Hallo together
I need access to tables in a MS SQL Server 2005 database.
One possibility is the JDBC driver.
How do i install this driver ?
Thank you very much for your postings.

Hi,
This is from the documentation -
Database: Third Party JDBC Drivers
The Third Party JDBC Drivers pane specifies drivers to be used for connections to third-party (non-Oracle) databases, such as IBM DB2, MySQL, Microsoft SQL Server, or Sybase Adaptive Server. (You do not need to add a driver for connections to Microsoft Access databases.) To add a driver, click Add Entry and select the path for the driver:
For Microsoft SQL Server or Sybase Adaptive Server: jtds-1.2.jar, which is included in the jtds-1.2-dist.zip download
To find a specific third-party JDBC driver, see the appropriate website (for example, http://www.mysql.com for the MySQL Connector/J JDBC driver for MySQL, http://jtds.sourceforge.net/ for the jTDS driver for Microsoft SQL Server and Sybase Adaptive Server, or search at http://www.teradata.com/ for the JDBC driver for Teradata). For MySQL, use the MySQL 5.0 driver, not 5.1 or later, with SQL Developer release 1.5.
You must specify a third-party JDBC driver or install a driver using the Check for Updates feature before you can create a database connection to a third-party database of that associated type. (See the tabs for creating connections to third-party databases in the Create/Edit/Select Database Connection dialog box.)
Alternative:
As an alternative to using this preference, you can click Help, then Check for Updates to install the JTDS JDBC Driver for Microsoft SQL Server and the MySQL JDBE Driver as extensions.
Regards,
Mike

Hi Chris,
A bug was logged for this a few days ago:
Bug 13547400 - CHECK UPDATES FAILS DUE TO SERVER RETURNED HTTP RESPONSE CODE: 400
This is similar to another bug which has already been fixed (not a product bug, just a bad URL in an OTN web page):

How to install jTDS jdbc driver

I've heard so much about this jTDS driver, and had it with the current jdbc driver i'm using. I'm using slserver 7. i would like to install the jtds driver. I just downloaded the .jar file. how do i install the driver. which directory do i put it in? pls help asap. thanks a million.

"Install" it?
The directory you put it in depends greatly on the application that's using it.
If it's a desktop app, put in in the CLASSPATH for the app.
If it's a Web app, put it in the WEB-INF/lib directory for your app.
It's not a cut & dried answer. I don't think one JAR file will necessarily serve all apps. Expect to have duplicates as needed. I do.

Install a JDBC driver

I have installed MySQL and downloaded the JDBC driver.
What is the proper way to install this driver on a weblogic application server 8.1?
Placing it in the server\lib or portal\lib didn't work.
I 've managed add it to the classpath in my domain's startWebLogic bat script, but that doesn't seem a clean way.

Howdy.
re doesn't seem like a clean way
I agree, but I think that's the way to do it. Someone else I'm sure will
correct me/you if we're wrong.
One alternative is to use the pre classpath and/or post classpath env vars.
Or something else, add a classes dir to your domain, and add that classes
path. It's a bit more visually understood where the third party jars are
located in that case.

BLOB support in standard postgresql jdbc driver - OutOfMemoryError

Hi all,
I have a problem with PostgreSQL and BLOBs.
Small BLOBs work, but with BLOBs of a certain size my code throws a java.lang.OutOfMemoryError.
The file I tried has about 2-3 MB.
Environment:
- PostgreSQL 7.2 on i686-pc-linux-gnu, compiled by GCC 2.96
- Mandrake 8.2
- 192 MB RAM
- blob column created as datatype "bytea" (maybe that is the problem)
- code posted below (BlobPostgresTest.java)
- console output posted below
- java command to run program:
    java -verbose:gc -Xmx128m -classpath .:pgjdbc2.jar BlobPostgresTest- java version as follows from "java -version" command:

Difficulty Installing the MySQL JDBC Driver

I am trying to install mySQL JDBC driver "mysql-connector-java-2.0.14.tar.gz" to link up with the mySQL server on a Windows XP OS.
The error is:
Cannot find database driver classes
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
I have read the USAGE AND INSTALLATION in the README file, but it can not seem to find these drivers still. I added the location to my PATH variable in the environment variables, and set CLASSPATH= ... as well and still can not find them
Paths i added to PATH and CLASSPATH variables
C:\j2sdk1.4.0_01\mysqlconnector.tar
C:\j2sdk1.4.0_01\JDBC
I did both methods it suggested, within the JDBC folder are the com and org folders. Anyone offer some suggestions.
I know some smart person is going to say just use linux, but it is needed for my father and he can barely use MS Windows.
Cheers for any help

Oracle JDBC driver 10.1.0.2.0

Hi All,
I have installed Oracle 9iR2 on Windows 2000 Advance server, and i am looking for Oracle JDBC driver 10.1.0.2.0 to be installed and configured, it would be real help if some one could send me the download path and how to continue further with installing the JDBC driver
Thanks,
Kumar

You can download the latest JDBC drivers from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
You just need to place the jar somewhere and add the location to your classpath.

Test JDBC Driver For SQL Server 2000 Failed

Hi:
I have trouble setting up the database connection using jdbc driver in the studio, could anyone help me please? I have MS SQL 2000 MSDE installed on my local machine. I downloaded and installed the JDBC Driver for MSSQL 2000 from Microsoft.
I put the following jar files into the/lib/ext/ directory
msbase.jar
mssqlserver.jar
msutil.jar
In Studio 4.1 EE, I went to Runtime>Databases>Drivers, Add a new Driver with these information:
Name: MSSQL Driver
Driver: com.microsoft.jdbcx.sqlserver.SQLServerDataSource
URL Prefix: jdbc:microsoft:sqlserver://localhost:<PORT>[;DatabaseName=<DB>]
Next I run the Test Driver...
Database URL: jdbc:microsoft:sqlserver://<machineName>\\<instanceName>;DatabaseName=<xxx>
User: <username>
Password: <password>
I receieved the a popup box and message in the output window:
Internal test driver incomplete. the driver may not support the required DatabaseMetadata methods. take a look at the Output Window for details.
Warning: No tables were found. Check your database.
Warning: No views were found. Check your database
Warning: No procedures were found. Check your database.
Your replies are greatly appreciated.

com.microsoft.jdbcx.sqlserver.SQLServerDataSource is a very old direct driver. I'd recommend using the DataDirect 3.2 driver. It can be found at:

Postgresql-jdbc on Suse Linux

Hi,
I am writing a Java Swing application on Suse Linux and want to add Embedded SQL to it. The application should interact with a PostgreSQL database running on my local machine. The compiler complains that it cannot find the org.postgresql package included in the code. I'm guessing the problem is that the classpath is not set properly. But when I try to add the postgresql-jdbc driver to the classpath using "export CLASSPATH=$CLASSPATH:/usr/share/pgsql/pg73b1jdbc1.jar", the program stops recognizing the other Java files it uses. How do I set the classpath up properly?
Code sample:
import java.awt.*;
import javax.swing*;
import java.sql.*;
import org.postgresql.*;
public class MyClass
public static void main (String [] args)
MyFrame frame = new MyFrame();
MyPanel panel = new MyPanel();
// more code here
MyClass.java:4: package org.postgresql does not exist
import org.postgresql.*;
^
1 error
Any help is much appreciated.
Marina.

Hi, I figured it out - thanks to JimDinosaur's response, although to a different thread. I am posting a reply in case other people had the same question.
So, I had two problems: first, the package wasn't recognized; second, the rest of the Java files used by the code.
Jim suggested to use javac -classpath, listing all the directories needed, for the packages and the files. So I did, with the files directory being my current directory:
javac -classpath /usr/share/pgsql/pg73b1jdbc1.jar:. CloningGUI.java
Jim, you rock! :)

JDBC driver installation

Hi,
I'm a newbie and just started programming in java. I dont know if this message is to be posted here or somewhere else. This is my first post. So please tolerate..
I use Fedora Core 4. I installed the JDBC driver (mysql-connector-java-3.1.12) for the mysql database as specified in the instructions. I copied the mysql-connector-java-3.1.12-bin.jar file to /root/jdk_nb/j2sdk1.4.2/jre/lib/ext and set the CLASSPATH environment variable in .bashrc as follows
export CLASSPATH=${PATH}:/root/jdk_nb/j2sdk1.4.2/jre/lib/ext
I also run the .bashrc file.
THen i executed a small program to get the names of the drivers loaded.
import java.sql.*;
import java.util.*;
class listJdbcDrivers
public static void main(String args[])
List drivers = Collections.list(DriverManager.getDrivers());
for (int i=0; i<drivers.size(); i++)
Driver driver = (Driver)drivers.get(i);
// Get name of driver
String name = driver.getClass().getName();
System.out.println(name);
// Get version info
int majorVersion = driver.getMajorVersion();
int minorVersion = driver.getMinorVersion();
boolean isJdbcCompliant = driver.jdbcCompliant();
System.out.println("Major Version"+majorVersion);
System.out.println("isJdbcCompliant"+isJdbcCompliant);
Then i did a javac listJdbcDrivers.. It compiled
Then i did a java -Djdbc.drivers=mysql-connector-java-3.1.12 listJdbcDrivers..
But it does not print out any drivers. Why is this happening?

That's a lot of chutzpah. No, I will not do your work for you.
DriverManager#registerDriver() adds a driver and registers it. I believe after you do this, getDrivers() would return that driver.
I also mentioned for completeness that instantiating a driver (via newIntance() on a class or via its constructor) normally results in that driver registering itself via DriverManager#registerDriver().
