Oracle JDBC driver does not handle Java empty strings correctly

If you store a Java empty string in a VARCHAR column, then try to retrieve it,
you get back a null.
Can someone from Oracle JDBC development
explain why this is not a bug? An empty
string is not the same as a null.

Hello!
Although all together different, but DATE type also behaves same way.
inserting createdate = NULL in database returns you blank on select query
inserting createdate= '' returns null on select. Correct me if i am wrong.

Package oracle.jdbc.driver does not exist!!

hi there..
am writing a JBDC application and i got the following error:
"package oracle.jdbc.driver does not exist"
what am i supposed to do??
well, am not sure, but i guess the above means that i dont have a JDBC driver for oracle; f i am right, where to get that from and how to install it (in terms of code and maybe enviroment variable)???
one more question: if i want connect to another DB engine than oracle, for example sql server or DB2, do i have to get a different driver??
Appreaciating ur cooperation
MOurad

Actually, if you're using JDK 1.4 or higher you should be using ojdbc14.jar from Oracle. classes12.zip is JDK 1.2 technology.
If you connect to another relational database you should always get the JDBC driver JAR from that vendor. They don't work across different databases. - MOD

Error oracle.sql.* and oracle.jdbc.driver.* not found when using oracle as a database

I am using oracle as database and weblogic 4.5. I have copied the classes12.zip file in lib directory of weblogic. I am getting the error that oracle.sql.* and oracle.jdbc.driver.* not found when i am importing these packages in a jsp file. what i need to do to import oracle driver packages?I put it in the classpath also.
Please Advice!
Thanks in advance

Hi Anupama,
First of all I would be surprised if you would not like to use the connection pooling feature of weblogic (in which case you might not be needing the import the classes directly), and would like to open direct connections to your database. Anyways for doing that I would recommend you to check out the readme doc that ships
along with the jdbc oracle (classes12.zip etc). I am giving an excerpt over here:
These are a few simple things that you should do in your JDBC program:
1. Import the necessary JDBC classes in your programs that use JDBC.
For example:
import java.sql.*;
import java.math.*;
2. Register the Oracle driver before before calling other JDBC APIs.
(This is not needed if you are using the JDBC Server-side Internal
Driver because registration is done automatically in the server.)
To register the Oracle driver, make sure the following statement
is executed at least once in your Java session:
DriverManager.registerDriver(
new oracle.jdbc.driver.OracleDriver());
3. Open a connection to the database with the getConnection call.
Different connection URLs should be used for different JDBC
drivers. The following examples demonstrate the different URLs.
For the JDBC OCI8 Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:oci8:@<database>",
"scott", "tiger");
where <database> is either an entry in tnsnames.ora or a SQL*net
name-value pair.
For the JDBC Thin Driver, or Server-side Thin Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@<database>",
"scott", "tiger");
where <database> is either a string of the form
<host>:<port>:<sid> or a SQL*net name-value pair.
For the JDBC Server-side Internal Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:kprb:");
Note that the trailing ':' character is necessary. When you use
the Server-side Internal Driver, you always connect to the
database you are executing in. You can also do this:
Connection conn
= new oracle.jdbc.driver.OracleDriver().defaultConnection();
Hope this helps,
Thanks,

JDBC driver does not support XA - Exception

JDBC driver does not support XA
cannot participate in a two-phase commit
To Force participation set EnableTwoPhaseCommit property on the corresponding JDBCTxDataSource property to true
1) What is a JDBCTxDataSource - what does the TX mean?
2) I have two data sources and according to BEA Weblogic docs, setting the property on both won't solve the problem. I tried.
3) When I try to change the data pools to use XA drivers, I get the following error on server startup:
java.sql.SQLException: Pool connect failed: java.lang.Exception: WebLogic Pool Driver doesn't support XA driver, Please change your config file to use a Non-XA driver

JDBC driver does not support XA
cannot participate in a two-phase commit
To Force participation set EnableTwoPhaseCommit

So use an XA driver.
TX usually means "transaction".

JDBC driver does not support XA

Hello,
we have the following problem when using oracle OCI jDriver from
WebLogic: when connection times out, we get the following error
javax.transaction.xa.XAException: JDBC driver does not support XA, hence
cannot be a participant in two-phase commit. To force this
participation, set the enableTwoPhaseCommit property on the
corresponding JDBCTxDataSourceproperty, to true.
(full message is attached as rtf file). We are not using TxDataSource
pools, just normal connection pools. This error only happens once in a
while. I would appreciate any help.
thanks

Open a support case. You can't even create an XA LLR datasource.

JDBC driver - Class oracle.jdbc.driver.OracleDriver not found.

Greetings:
When I tried to compile an test script (as attached below) to test the driver, I always ended up with the following error message:
....java:17: Class oracle.jdbc.driver.OracleDriver not found.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Could somebody shine some light on it? I would very much appreciate it.
By the way, I have an Oracle DBMS (8.1.7) with jre1.1.7. My Java is jdk1.2 and the driver is ocijdbc8.dll
Wil
*************** The test script *************
import java.sql.*;
class Users
public static void main (String args [])
throws SQLException, ClassNotFoundException
// Load the Oracle JDBC driver
Class.forName ("oracle.jdbc.driver.OracleDriver");
// Connect to the database
// You can put a database name after the @ sign in the connection URL.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@US10", "QM24202E", "QM24202E");
// Create a Statement
Statement stmt = conn.createStatement ();
// Select ... table
ResultSet rset = stmt.executeQuery ("select USERID from USERS");
// Iterate through the result and print the ... names
while (rset.next ())
System.out.println (rset.getString (1));

check out what thomas Fly wrote on another discussion forum about connection with JDBC, i tried it and i haven't gotten it
to work yet but at least i don't have the "... not found" error,
you should try it too, and i think it's good to tell you that i
still haven't installed the oracle client on my windows Me PC.
Hope this help you
This may help also... I have Oracle installed on a Linux PC at 192.168.1.4 on my LAN, listening on port 1521. I can connect from another PC (Linux / Windows ME dual boot, though running Windows at the time of this experiment) using the following program:
import java.sql.*;
public class sqlLookup {
public static void main(String[] args) throws SQLException, ClassNotFoundException {
String dbUrl = "jdbc:oracle:thin:@192.168.1.4:1521:ORA8";
String user = "thomasfly";
String password = "maverick";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection c = DriverManager.getConnection(dbUrl, user, password);
Statement s = c.createStatement();
// SQL code:
ResultSet r = s.executeQuery("select * from members");
while(r.next()) {
// Capitalization doesn't matter:
System.out.println(r.getString("Name") + ", " + r.getString("id") + ": " + r.getString("email") );
s.close(); // Also closes ResultSet
I downloaded classes12.zip for Oracle 8.1.7 and put it into the C:\Windows directory, and mounted C:\Windows\classes12.zip in Forte for Java (equivalent to adding it to the classpath if I were running the program from a DOS window, rather than in Forte).
ORA8... capitalization may be important... is the name of my database, which may be found in the tnsnames.ora file in $ORACLE_HOME/resources.
The query gets the Name, id, and email fields from the table "members" in the database.
This is just a barebones program, and each time it's run, the Oracle listener has to be stopped and restarted before the program can be successfully run again.

JDBC driver does not support XA, hence cannot be a participant in two-phase

Hi
I have a question, we enabled "One Phase Commit", even though we are getting "javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source =nested exception is: javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source". Why is that?
Thanks
Edited by: user7256072 on Apr 10, 2012 12:35 PM

Is there more than one resource participating in the transaction?
If this is the case, and the resources are for example a database and JMS, you can emulate XA
by using the logging last resource setting on a non-XA driver.
An example of the above is presented here: http://middlewaremagic.com/weblogic/?p=7716 (the section my first JavaEE6 application)
Here a stateless EJB is used that has an insertPerson method that uses a datasource and JMS in a transaction.

JDBC driver does not support XA,,hence cannot be a participant in two-phas

Error committing transaction:; nested exception is: javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source = SOADataSource
i have enabled the LoggingLastResource option still it is not working showing the same error.
i have a doubt in this case my datasource is of type XA then is there any need to enable any of the above option(LoggingLastResource (recommended) or EmulateTwoPhaseCommit).
please do reply it has hampered many of the tasks.

Open a support case. You can't even create an XA LLR datasource.

Package (import oracle.jdbc.driver.*) not found -----URGENT--------

Hi All,
i've been using oracle thin driver for oracle 9i server since a long. but now it gives error like
package import oracle.jdbc.driver.* not found
it seems some problem in classpath.
but i've inludeed classes111.zip/classes12.zip to classpath and with this was working fine. dunno what's the problem . kindly mail me at the earliest to:[email protected]
also i'm working with Tomcat server.
to run the servlet i don't want to type the absolute url like
http://localhost:8080/servlet/test rather http://localhost/test .so how to config it . can ne one tell me asap.
with thanx abd rgds
Sayed
so can u tell me

1. Copy classes12.zip to %TOMCAT_HOME\common\lib
2. Go to %TOMCAT_HOME\common\lib dir, rename classes12.zip to classes12.jar
I think someone else has reply same problem before, next time you can do a search before post your problem.

check the classpath and path

Update of MySQL and SQL Server JDBC Driver does not work in 1.2.1

Hi,
always after the update process is started i got the MySQL and SQL Server JDBC driver
update notification.
But all the time after i install the update i got the notification again but no errormessage
that the update was maybe not successful ???
Frank

Ok
then my subject was false
i always try to update the extensions and now i can see that they are updated on the filesystem but the IDE does not recognize them as updated
....\sqldeveloper\sqldeveloper\extensions\oracle.sqldeveloper.thirdparty.drivers.mysql
is available and new after the update process
and under
...\sqldeveloper\sqldeveloper\tmp\update\oracle.sqldeveloper.thirdparty.drivers.mysql.5239.zip
the downloaded zip file is also available.
In the update window the message is that the extension with version 5206 is available
Maybe that is the problem cause the downloaded files are version 11.1.1.5239
if you look at the bundle.xml file inside the META-INF directory

32-bit Oracle ODBC Driver does not work under Windows 64-bit

We have both Oracle Server 64-bit (10.2.0.3) and Oracle Client 32-bit (10.2.0.1) installed on the same Windows 2003 64-bit server.
We can create and test 64-bit Oracle ODBC System DSN using 64-bit ODBC Administrator.
We can also create a 32-bit Oracle ODBC System DSN using 32-bit ODBC Administrator.
However, the "test connection" does not work:
Unable to connect
SQLState=IM003
Specified driver could not be loaded due to system error 998 (Oracle in OraClient10g_home32)
We need the 32-bit driver due to 32-bit applications acessing the local 64-bit Oracle server.
How should we accomplish this?
Thanks.

I applied 10.2.0.3 path to Oracle Client 32-bit and now the error is different.
This error message appears 3 times before configuring, creating or testing a System DNS:
"An unsupported operation was attempted."
I just click OK 3 times and then can configure, create or test the DSN.
However the 32-bit application still cannot access Oracle...

Oracle.jdbc.driver.OracleDriver not found in Sun ONE Studio

I get this message when I try to connect to the database while creating an EJB. I have tried adding the path to my CLASSPATH, and to adding it to the various CLASSPATHs within Sun ONE Studio. IDE_HOME is defined correctly but OracleDriver.class is still not found. Anyone know what my problem might be?
Thanks,

Hi Sujatha,

Which as you can see includes classes12.zip and /export/oracle/oem_webstage/oracle/jdbc/OracleDriver.class
I have also set all the IDE internal classpath variables to the same settings. It has no effect. I still get the same message.
