Oracle.jdbc.driver.oracleResultSet Vs java.sql.ResultSet

Hi all
Could any one got any idea on this problem...
My application program is forced to use both Java Result Set(java.sql.ResultSet) and Oracle ResultSet(jdbc.driver.oracleResultSet).
This on javac get compiled and is working fine....
But when i try to compile with vbjc(visibroker-java compiler)... it failes to compile...
throwing ...
.."The method oracle.jdbc2.Blob getBlob(int) declared in class oracle.jdbc.driver.OracleResultSet cannot override the method of the same signature declared in interface java.sql.ResultSet. They must have the same return
type."

Hi Prowzen,
Ur reply was much userful, which gave me a direction to prob into... Thank You Very MUCH.
I relpaced
BLOB blob = ((OracleResultSet)rs).getBLOB(int);
with
oracle.sql.BLOB blob =(BLOB)rs.getObject(int);
So eliminating usage of OracleResultSet, the conflicts got cleared...
Keep writing...

Java.lang.AbstractMethodError: oracle.jdbc.driver.OracleResultSet.isLast()Z

Hello.
I'm trying to detect if a row is the last one of a ResultSet (from a
executeQuery):
ResultSet results = sql.executeQuery();
if (results.isLast())
     out.println("EMPTY");
But I get this error message:
Error 500

What am I doing wrong?
Thank you very much.

What do you want to do with a RS instead at least 1 next() ?
Only 1 next() - then you know, if it is empty.
If it's not empty, I assume you will do any retrieval, so you will have needed at least this first next(), don't you?
Even if you would like to skip the first row (though you have retrieved it), it would not be too much costs.
If you don't want to retrieve but only count your rows, do a query "SELECT COUNT(*) FROM table WHERE <your condition ...>".
However, to get the count you would have to do one - only one - next() call.

Java.lang.AbstractMethodError: oracle/jdbc/driver/OracleResultSet.getBlob

Hi,
I am using WSAD 4.0.3. While I am running application I am getting this error.
[10/5/02 13:26:17:984 GMT+08:00] 7a483a9b ExceptionUtil X CNTR0020E: Non-application exception occurred while processing method lodge on bean BeanId(CePAC#CePACEJB.jar#CfsControllerBean, f0b300abe8): java.lang.AbstractMethodError: oracle/jdbc/driver/OracleResultSet.getBlob
I have set the classpath i.e classes111.zip. This function is to insert record to a database having blob field.
Waiting for a quick response.

java.lang.AbstractMethodErrorIn jdbc that often occurs because you are using a newer version of JDBC (the jvm) and an older driver. It occurs because you called a method which exists in the newer JDBC but does not exist in the older driver.
getBlob() was introduced in java 1.2, so it was not in JDBC 1.0.

My JSP works fine using Sun's JSWDK and Jakarta-Tomcat. I just started using WebSphere Application Server v3.5 and now my JSP blows up at "rs.getBigDecimal"
I'm using WebSphere v3.5, JDBC 2.0(classes102.zip), and JDK 1.2.2
What can I do to fix this?
Thanks,

Bad support for ts hint in Oracle jdbc driver (for preparedStatement)

hi
I have the following SQL
SELECT TRUNC({ ts '2004-01-01 00:00:00.0' }) FROM ET1_ELEMENT
With the jdbc.odbc driver the following meta data is returned:
ResultSet meta data are...
Column [1]
name [TRUNC(TO_DATE('2004-01-0100:00]
type [93]
class name [java.sql.Timestamp]
which is fine.
Nevertheless with Oracle thin driver I got an SQL exception:
The SQL Error is:
ORA-00932: inconsistent datatypes: expected NUMBER got TIMESTAMP
internal exception:
(class java.sql.SQLException):
java.sql.SQLException: ORA-00932: inconsistent datatypes: expected NUMBER got TIMESTAMP
If I use the TO_DATE in the sentence (e.g. t_date('2004-01-01 00:00:00','YYYY-MM-DD HH24:MI:SS')) everything is fine on both driver.
Any idea on the problem? Is it a bug?
Thanks

Mikael,
I couldn't ascertain your environment from your post, so the below may be irrelevant for you. But in the hope that is isn't...
I tried your example on an Oracle 9i (9.2.0.4) database on SUN [sparc] Solaris 9, with J2SE 1.4.2_04 and the "ojdbc14.jar" [JDBC] driver. If I remove the "trunc" function, then I do not get an Oracle error. I must admit, though, that I don't understand why you need to trunc(ate) a literal value. All that the "trunc" function does is set the time part -- the hours, minutes, seconds, etc. -- of your timestamp to (all) zeroes -- which is what you have in your literal, anyway, so why the need for "trunc"?
I believe the Oracle JDBC driver converts the java sql-escape syntax -- "{ts '2004-01-01 00:00:00.0'}" -- to a call to the "to_date" function, anyway. Possibly one way to verify this would be to use P6 Spy. If I am correct, then it would only be logical that Oracle allows you to use the sql-escape syntax wherever it is all right to use the "to_date" function. But then again, I guess that
select trunc(to_date('2004-01-01 00:00','YYYY-MM-DD HH24:MI')
from ET1_ELEMENTis allowable syntax anyway. So I guess maybe that this may be a bug in the JDBC driver. Have you checked the MetaLink Web site?
Good Luck,
Avi.

Hello Paul,
Thanks for you suggestion. Based on it , I did add the exact jar file in the PATH environmental variable in XP.

I guess SessionBean1 is not serializable perhaps because it doesn't implement Serializable, and the writeObject method in StandardSession is trying to write it to disk (trying to serialize it).
Try changing SessionBean 1 to
public class SessionBean1 implements Serializable{
}

SchemaTool() throws ClassNotFoundException: oracle.jdbc.driver.OracleDriver

KODO 2.5.3
I am trying to use the SchemaTool java class for schema manipulations. When
I try to construct a SchemaTool object I get the following exception:
com.solarmetric.kodo.runtime.FatalUserException:
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
NestedThrowables:
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
I am passing an instance of MultiLoaderClassResolver (constructed using a
custom URLClassLoader) as the ClassResolver argument to the SchemaTool
constructor. The orcale jar "classes12.jar" is one of the URLs in the
URLClassResolver. Before constructing a SchemaTool object, a call to
canResolveClass("oracle.jdbc.driver.OracleDriver") on the class resolver
returns true. So why is SchemaTool not able to find this class?
Thanks
Vijay

Marc,
It might well be problems with my custom class loader (which are a pain to
debug indeed) or my lack of understanding of some of your schema tool
classes, but the basic problem I encountered (before getting to the Logger
issue) is as follows:
I have an instance of MultiLoaderClassResolver constructed using my custom
class loader.
A call to resolveClass("orcale.jdbc.driver.OrcaleDriver") on this instance
returns the correct Class (does not throw a ClassNotFound exception).
The same MultiLoaderClassResolver instance is passed as an argument to
SchemaTool(). SchemaTool.refresh() throws an exception:
ClassNotFound: orcale.jdbc.driver.OrcaleDriver
So it seems to me that somewhere in the SchemaTool code you are trying to
resolve orcale.jdbc.driver.OrcaleDriver using something other than the
instance of MultiLoaderClassResolver that I passed in. From the stack trace
in my earlier message, it seems like that is happening in:
com.solarmetric.kodo.impl.jdbc.ormapping.ClassMapping.createPKColumns(ClassM
apping.java:1584)where an instance of ConfigurationConnector is constructed. BTW, this is how
I construct and pass a ConfigurationConnector to SchemaTool:
JDBCConfiguration conf = new JDBCSimpleConfiguration(someProps);
ClassResolver resolver = new MultiLoaderClassResolver(myCustomClassLoader);
Connector connector = new ConfigurationConnector(conf, resolver, false);
SchemaTool sTool = new SchemaTool(conf, resolver, connector);

Vijay-
Custom ClassLoader problems are often very hairy to debug. The first
error message you are receiving indicates a problem:
org.apache.commons.logging.LogConfigurationException: Class
org.apache.commons.logging.impl.Log4JLogger does not implement LogThis indicates to me that the
"org.apache.commons.logging.impl.Log4JLogger" and
"org.apache.commons.logging.Log" classes are being loaded in different
ClassLoaders, which is generally a bad thing. Is your URLClassLoader
deferring to the parent ClassLoader?
I think that the first step is to identify why the class loaders are
different for these two classes (which should be easy to do with some
printlns in a test program that uses your URLClassLoader).
Bear in mind that this isn't technicall a Kodo issue, but a general
ClassLoader issue. However, we are happy to try to provide hints and
guidance about how to isolate the source of the problem.

Adding the following line before the schema related code solves theproblem:
Thread.currentThread().setContextClassLoader(myCustomClassLoader);
However, that causes another error which, from a brief look at
LogFactoryImpl, seems surely related to custom class loaders. Don't knowhow

My guess is that your custom classloader is preventing instanceof. Can
you try using the system classloader or see if java.sql.Driver is
assignable from oracle.jdbc.dirver.OracleDriver?

I use Java Web Service Developer Pack 1.0 on Win98 SE, database Oracle 8.1.7 is installed on dedicated IBM server (AIX 4.x).
I put these lines in autoexec.bat:

set CLASSPATH=.;C:\j2sdk1.4.0\lib\tools.jar;C:\j2sdk1.4.0\lib\classes12.zip;C:\j2sdk1.4.0\lib\classes111.zip;%CLASSPATH%

set JAVA_HOME=C:\j2sdk1.4.0

I have the same problem. I created a JSP page that uses a class to retrieve database information. I added a main method to the class so I would be able to test it. When I test the class using the main method the method returns all the information from the database. When I try it using Tomcat, I get the following error: java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
Does anyone have an idea of what is going on?
My CLASSPATH configuration is the same.

JDBC,Oracle - java.lang.ClassNotFoundException: oracle.jdbc.driver.Oracle

I am using JBuilder5 which comes with jdk1.3. I have installed oracle 8.1.7 Enterprise version.
I am using Win NT 4.0.
I have set the PATH variable as E:\oracle\ora81\lib; and
CLASSPATH as : E:\oracle\ora81\jdbc\lib\classes12.zip;E:\oracle\ora81\jdbc\lib\nls_charset12.zip;
My JDBC code is
package sample2;
import java.sql.*;
public class Two {
Connection con;
Statement st;
public Two() {
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection("jdbc:oracle:oci8:@First","scott","tiger");
st = con.createStatement();
ResultSet rs = st.executeQuery("Select * from Book");
while(rs.next())
System.out.print(rs.getInt("ID")+"\t");
System.out.print(rs.getString("title")+"\t");
System.out.print(rs.getString("author")+"\t");
System.out.print(rs.getString("subject")+"\t");
System.out.println(rs.getInt("copies")+"\t");
st.close();
con.close();
catch(Exception ex)
System.out.println("Exception : " + ex.toString());
public static void main(String[] args) {
Two two1 = new Two();
I am getting this exception:
Exception : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
I can understand that the classpath for the driver is the problem here.
Also, I tried to run this file without JBuilder as a independent file on a notepad. Even then this exception is thrown.
I have set the PATH to E:\oracle\ora81\bin and also to E:\oracle\ora81\lib.
I ran "echo %classpath%" from my command prompt and this is what i am getting.
E:\JBuilder5\jdk1.3\lib\tools.jar;E:\JBuilder5\jdk1.3\dt.jar;E:\oracle\ora81\jdbc\lib\classes12.zip;E:
\oracle\ora81\jdbc\lib\nls_charset12.zip;
I searched solution for this probldem in Sun JDC Forum itself. Many of them suggested to unzip classes12.zip and create jar file and add it in the classpath. Alos, some have suggested to copy the classes12.zip in home directory and then include this path in the classpath. I tried those solutions also. But, nothing seem to work.
Somebody help me fix this problem.
Thanks in advance.

Jbuilder5 uses a different means of loading dependent classes. Use menu : Tools -->Configure Libraries - Click New and setup a new named library that points to classes12.zip .
Then include this in u'r required Libraries of your project using menu Project --> Project Properties - required Libraries tab.
I don't thnk Jbuilder5 even refers to CLASSPATH set in Windows NT environement. Path may need to be set to include oracle/ora81/bin directory though.
Hope this helps.

Java.lang.AbstractMethodError: oracle.jdbc.driver.OracleDatabaseMetaData.lo

I am evaluating the sun RI of javax.sql package . I downloaded the jdbc_rowset_tiger-1_0_1-mrel-jwsdp.zip package and installed in my machine.
I tried the JdbcRowSet implmenation and it worked pretty smooth. I wanted to try the disconnected Rowset implementation. I tried CachedRowSet Implementation with thin driver. I get the following error message.
Exception in thread "main" java.lang.AbstractMethodError: oracle.jdbc.driver.OracleDatabaseMetaData.locatorsUpdateCopy()Z

I am using thin driver with Oracle8i db.
Appreciate any early responses

I had the same problem initially.
I fixed it by downloading an updated ojdbc14.jar (1).
It may be because I downloaded the ocrs12.jar from there a bit earlier and the versions of ojdbc14.jar and ocrs12.jar need to match (that is, come from the Oracle10g suite of jars).
Here is the class I used:
import java.sql.*;
import javax.sql.*;
import com.sun.rowset.WebRowSetImpl;
import com.sun.rowset.providers.RIXMLProvider;
public class test {
public static void main(String[] args) {
    try {
      Class.forName("oracle.jdbc.driver.OracleDriver");
      WebRowSetImpl wrs = new WebRowSetImpl();
      wrs.setCommand("select table_name from user_tables");
      wrs.setUsername("scott");
      wrs.setPassword("tiger");
      wrs.setUrl("jdbc:oracle:thin:@paramount.com:1521:ORCL");
      wrs.execute();
      wrs.writeXml(System.out);

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,

few of my colligue are using the same database, and
they are not getting these kind of error. Only my
system and 2 more system is giving these problem.
All of us are using the same version of oracle
only.I said driver not database.

Additionally you might want to check your class path to verify that only what is required is in that.
You haven't put anything in the ext directory have you?
