something elseYeah, the problem must be in Oracle. It couldn't be you or your code. That's perfect, of course.
Call Larry Ellison and demand that he fix that stinking pile of c-r-a-p code he's sold you.

NoClassDefFoundError: oracle/jdbc/OracleDriver

I have a servlet that is supposed to connect to an oracle database select from a table and then return the results. This works in JDeveloper but when I try to deploy it to tomcat I get an error saying the following.

     at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
How can I resolve this problem ?

I have the same problem.
I wrote a simple program as follows.
import java.sql.*;
import oracle.jdbc.*;
import oracle.sql.*;
public class OracleConnect
public static void main (String args []) throws SQLException
          DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
     Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@10.0.0.8:1521:ORCL","scott","tiger");
     Statement stmt = conn.createStatement ();
          ResultSet rset = stmt.executeQuery ("SELECT ename FROM emp");
          while (rset.next ())
     System.out.println (rset.getString (1));
rset.close();
stmt.close();
conn.close();
I am compiling like this.
C;>javac -classpath c:\oracle\ora92\jdbc\lib\classes12.jar;c:\oracle\ora92\jdbc\lib\nls_charset12.jar;. OracleConnect.java
Everything is fine upto now.
But at the time of execution
C:\>java OracleConnect
Java is crying like this.
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/OracleDri
ver at OracleConnect.main(OracleConnect.java:11)
Can any one help me to resolve this issue please? By the way, I did not install Jdeveloper. I am using command prompt to do the stuff.

Need help on Oracle Report format

Hi,
I need help on Oracle Reports. I am generating a report in excel sheet. I have a column which is 13 digit number (In database it is CHAR datatype). In excel sheet it showing some thing like 9.78381E+12. I want to show complete number like 9783805591331.
Also sometimes leading zero's are not showing when my column values is something like 0098794859583. I need to show the leading zero's as well in excel without losing them.
Below are the parameters i am using for the report
DESFORMAT=SPREADSHEET AND DESTYPE=FILE
My Oracle 9i developer version.
Any help on this would be much appreciated.

I need help with oracle

Hi,
I need some help... if someone can help its great.
I need to make a statement in Oracle SQL that read data from a file and insert in a Oracle Database ... if someone can show me the syntax of it i appreciate..
Thanks

Okay, I see you followed the advice in that other thread and started a new post for you question. Congratulations. Your next lesson in forum etiquette is to give your posts a more relevant subject. Pretty much everybody who posts here needs help with oracle; if they need help with cooking catfish they've come to the wrong place.
It that other thread I suggested using SQL*Loader or External Tables might be a more suitable solution. Find out more.
Cheers, APC

Connect to an Oracle database by using oracle.jdbc.OracleDriver: error

Hi,
I'm trying to connect to an Oracle database so we can retrieve notes of tables, views and packages.
By using the API of Data Modeler (transformation script) we want to add these notes to corresponding objects in Data Modeler.
I'm starting with this:
importPackage(java.lang);
importPackage(java.awt);
importPackage(java.sql);
java.lang.Class.forName("oracle.jdbc.OracleDriver");
An error occurs when I run this code:
It has to be a Java thing...
Anyone a suggestion?

Problem solved! One of my colleagues referred to this post: Import user defined properties from Oracle Designer
More in detail: it's about this couple of lines:
// Copy the ojdbc6.jar file to ..\datamodeler-home\jlib directory
// Add this line to datamodeler.conf
// AddJavaLibFile ../../jlib/ojdbc6.jar
I changed my datamodeler.conf file, restarted DM and now there's no longer an error when I am trying to use the Oracle JDBC drive.

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?

Location of 'oracle.jdbc.OracleDriver'

Hi everyone,
I am starting out learning JDBC and am trying to compile and run this sample Java program:
package project1;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import oracle.jdbc.OracleDriver;
public class jdbc_test1 {
* @param args
* @throws SQLException
public static void main (String[] args) throws SQLException {
try {
DriverManager.registerDriver(new OracleDriver());
catch (SQLException e) {
e.printStackTrace();
Runtime.getRuntime().exit(1);
When I 'make' the project, I get the error 'OracleDriver not found' on the 'import' line.
My environment:
Windows Vista
Oracle 10.2.0.3.0
JDeveloper 10.1.3.3 and 11.1.1
CLASSPATH: .;d:\App\Oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar;d:\App\Oracle\product\10.2.0\db_1\jlib\orai
18n.jar
I searched both jar files looking for OracelDriver, but found nothing. What am I missing?
Thanks.

I get the error 'OracleDriver not found' Note that this kind of driver to be imported is depreciated.....
http://forums.oracle.com/forums/ann.jspa?annID=201
As a substitution for this use....the following packages....
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.OracleDataSource;
and make then the appropriate changes in your main() method... such as:
public static void main(String args[]) throws Exception
   Connection con =null;
   try
     OracleDataSource ods = new OracleDataSource();
     ods.setURL("jdbc:oracle:thin:scott/tiger@//<host_name>:<listener_port>/<your_tns>");
     con = ods.getConnection();
   catch (Exception ex)
     //System.out.println("Unable to connect..."+ex.printStackTrace());
     System.out.println("Unable to connect..."+ex);
     System.exit(-1);

Need help with Thin JDBC connecting Oracle to SQL server.

I am fairly new to JAVA. We have ORACLE 8.1.7 running on Solaris 8. I have a need to
periodically extract data from ORACLE DB and transfer it to SQL Server. I am limited to
moving data from the ORACLE/UNIX environment to SQL Server side.
From what I have read, Server-side Thin driver should work.
1) Are there any issues in trying to achieve this with ORACLE running on the UNIX platform?
2) Will the Server-side Thin driver talk to both the DBs ?
3) Is it possible to provide some sample code ?
Thanks in advance,
Solomon

Quattro,
I had complete success in reading from Oracle and writing to SQL Server. First of all let me thank you for all your help. I do have one last request. Its more on optimization than any thing else.
I was trying to optimize my code by grouping both the connections in one place and to keep my reads and inserts together so that I don't commit at the end of each insert etc. I don't seem to have the scope rules under control yet. Could you suggest how to improve this:
import java.sql.*;
public class Test_Combined2 {
public static void main(String args[]) throws SQLException {
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database
// You must put a database name after the @ sign in the connection URL.
// You can use either the fully specified SQL*net syntax or a short cut
// syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
Connection con2 = DriverManager.getConnection ("jdbc:oracle:thin:@Test:1521:PSDEVElOP",
"SOLOMON","SOL1");
// Create a Statement
Statement stmt2 = con2.createStatement ();
String url = "jdbc:microsoft:sqlserver://INTRADEV:1433;DatabaseName=Measure";
Connection con;
String query = "select dataYear, dataMonth, yieldRate from tblYield " ;
Statement stmt;
try {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.print(e.getMessage());
// Select the ENAME column from the EMP table
ResultSet rset = stmt2.executeQuery ("select year_start, monthofyear, percent_comp " +
" from ps_usm_ytd_yield ");
// Iterate through the result and print the employee names
while (rset.next ()) {
System.out.println (rset.getFloat (3));
int ps_dataYear = rset.getInt(1);
int ps_dataMonth = rset.getInt(2);
float ps_yieldRate = rset.getFloat(3);
try{
con = DriverManager.getConnection (url, "tmpuser","tmppush");
stmt = con.createStatement();
PreparedStatement insertTblYield;
String insertString = "insert into tblYield " +
" values(?, ?, ?)";
//con.setAutoCommit(false);
insertTblYield = con.prepareStatement(insertString);
insertTblYield.setInt(1, ps_dataYear);
insertTblYield.setInt(2, ps_dataMonth);
insertTblYield.setFloat(3, ps_yieldRate);
insertTblYield.executeUpdate();
con.commit();
//con.setAutoCommit(false);
/*ResultSet rs = stmt.executeQuery(query);
System.out.println("dataYear, dataMonth, yieldRate");

It's been working, just I got this error today only, all other services are working fine.
Has anyone got this error?
Any help would be greatly appreciated.

Need help on Oracle Application Testing Suite

Hi,
I need help on accessing one script into another script in OATS like the way we access methods of one class into another class in Java. I have created 2 scripts (when i do recording they created as a projects in open script editor), now i want to use my first script in second script.
Thanks,
VaraPrasad

I have a similar problem with the OATS v9.20 installation. I did manage to install it on our main load generator (running Windows 2003 Server) but when it came to installing OpenScript on my laptop (XP SP3) the install 'hangs' at 78%.
I did raise a support call with Oracle about this (there was a bug report generated) but the case is still open.
I've been waiting to hear when the next version was due (in the hope that this might have been resolved) but by the sounds of it there could still be an issue on WinXP with v9.21?
For reference I originally logged this with the following in the description:
The installation looks like it is failing because of a double backslash in a path ending "OATS920\\bin\copyOUI.bat". We then get an error in javaw.exe which when OK'ed then stops the installation at the stage "creating 'Uninstall Oracle Application Testing Suite' in folder 'Oracle Application Testing Suite' ".
