CLASSPATH=/tools/oracle/9.2.0/jdbc/lib/ojdbc14.jar
What I have to put in the CLASSPATH, please ???

Please don't cross post.

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:

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.

Error : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Hi,
I am writing an application and am trying to open a connection to Oracle database that is on a server. I am using the following test code to check if it connects to the database.
import java.sql.*;
class dbAccess {
public static void main (String args []) throws SQLException
        String DBurl = "jdbc:oracle:thin:@local:1522:DBORA";
        String user = "test";
        String pwd = "test123";
        Class.forName("oracle.jdbc.driver.OracleDriver");
        con = DriverManager.getConnection(DBurl, user, pwd);
}On running the above program I keep on getting the following error:
Error : java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
java.lang.NullPointerException
If I open the connection using JDeveloper wizard I can see the DB. But if running the above program in the JDev, JCreator or commandline keep on getting the error. Any help is appreciated. Thanks

How do I set the path for the Oracle Driver. ThanksI dunno. You're supposed to know where that class is (what jar it lives in). You set it up in JDeveloper in the first place, so you must have known where it is. After you know that, it's up to you to figure out how JCreator projects are set up to include jars in a project (just like JDeveloper projects do). For the command-line way, you set the classpath on the command-line arguments:
java -cp (your classpath here, which must include the jars it needs) ...

Hello Paul,
Thanks for you suggestion. Based on it , I did add the exact jar file in the PATH environmental variable in XP.
Path=C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar;C:\oraclexe\a
pp\oracle\product\10.2.0\server\bin;C:\oracle\product\10.2.0\client_1\bin;C:\Ora
cle\product\10.1.0\Client_1\bin;C:\Oracle\product\10.1.0\Client_1\jre\1.4.2\bin\
client;C:\j2sdk1.4.2_06\bin;Even after adding the specific jar file *("C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar")* ..I am getting the exact same error. moreover, to verify this I also tried to import import oracle.jdbc.driver.*.....and now my code would not even complie and I get error *(c:\Program Files\Java\jdk1.5.0_13\bin\OraThin.java:3: package oracle.jdbc.driver*
does not exist ) . I also rebooted my machine just to make sure ...that didnt work either. Also, I changed these jar to be first in the PATH varibale ..to avoid conflict with any later .jar's classes. The code is :
import java.io.*;
import java.sql.*;
import oracle.jdbc.driver.*;
public class OraThin {
public static void main(String[] args) {
    try {
System.out.println(System.getProperty ("java.class.path") );
      Connection con=null;
      Class.forName("oracle.jdbc.driver.OracleDriver");
      con=DriverManager.getConnection(

      s.execute("SELECT SYSDATE FROM DUAL");
      s.close();
      con.close();
} catch(Exception e){e.printStackTrace();}
}What am I missing here!! ?
Thanks again,

Error loading driver: java.lang.ClassNotFoundException: oracle.jdbc.driver.

Hi!!!
I�m trying to execute a example program included in http://archive.coreservlets.com/, the file is FruitTest.java....this compile very well...but....when i tried to execute it i have the following error:
Error loading driver: java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
Could somebody tell me what i have to add to my classpath?...and how to know if i have to download something and in what link is it?......
Thanks in advance...

Hi mary,
Please try following code, but before that please include classes12.zip in ur classpath. This file contains the oracle thin driver.
Connection connection = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@dbUrl"
connection = DriverManager.getConnection(url, "dbName", "password");
}catch (Exception e){
e.printStackTrace();
good luck ...san :-)

Hello.
I'm trying to detect if a row is the last one of a ResultSet (from a

if (results.isLast())
     out.println("EMPTY");
But I get this error message:

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.

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.

What you should be realizing is that Tomcat doesn't give a hoot about your system CLASSPATH. It totally ignores it. You really shouldn't even have one, because IDEs and app servers don't even take it into account. Get rid of it.
You're making lots of mistakes here:
(1) The Tomcat docs explicitly state that it won't look inside ZIP files. Change it to a JAR file.
(2) You're using JDK 1.4.1 and classes12.zip? You realize, of course, that there's an ojdbc14.jar available for download from Oracle. Go get it.
(3) Put the JDBC JAR in the WEB-INF/lib directory of your Web app. If you don't have one, you're not deploying your Web app properly.
(4) You've got Java code with empty catch blocks? That's one of the most foolish things a person can do. If an exception's thrown you'll never know it. For goodness sake, at least print the stack trace.
(5) Why do you have those Oracle imports? That ties your code to Oracle. The design of the java.sql package lets you use interfaces. Why don't you write JDBC the way it was meant to be written?
(6) Why aren't you setting up a JNDI data source?

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);
    } catch (Exception e) {
      System.out.println("Exception:"+e);

Two thoughts.
The first is that 10.2.0.1 is unpatched. Why? It has been two years since its release and no one has applied 10.2.0.2, 10.2.0.3 or 10.2.0.4.
The second is that your question is not a database question but a Java question is you are more likely to get an answer that will help you if you post in a group where it is on-topic.

500 Internal Server Error java.lang.NoSuchFieldError: oracle.jdbc.oci8.OCI

I am running small SQLJ in a JSP to get the hang of it.
I am running on 920, and have downloaded the new runtime classes for 920 and tested per the instructions.
Using JDev 903, here is the private method for running a query ( It is from an article I found by Julie Basu at Oracle; I have played around with the empno/emp_no variable to convert it to an int):
<%! private String runQuery(String emp_no) throws java.sql.SQLException {
DefaultContext dctx =null;
String ename = null; double sal = 0.0; String hireDate=null;
StringBuffer sb = new StringBuffer();
//int emp_no = Integer.parseInt(emp_no);
try {
dctx =Oracle.getConnection("jdbc:oracle:oci8:@olap","scott","tiger");
#sql [dctx] { SELECT ename, sal, TO_CHAR(hiredate,'DD-MON-YYYY')
INTO :ename,:sal,:hireDate
FROM scott.emp WHERE empno=:emp_no
sb.append("<BLOCKQUOTE><BIG><B><PRE>\n");
sb.append("Name :"+ename+ "\n");
sb.append("Salary :"+sal+ "\n");
sb.append("Date hired :"+hireDate);
sb.append("</PRE></B>></BIG></BLOCKQUOTE>");
} catch (java.sql.SQLException e){
sb.append("<P> SQL Error: <pre> "+e+" </pre> </p>\n");
} finally {

return sb.toString();

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?

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.
