SQLJ error: "Exception in thread main java.lang.NoClassDefFoundError: sqlj/

Question

Hi,
I am new to SQLJ. Now, in my PC (with Win98), I have JDK 1.2 and Oracle 8i (personal edition). I have used Java and Oracle in my PC without any problem. Now, I am going to learn SQLJ in order to create a java program to access Oracle database. What I have done is to set up several classpaths in DOS:
SET classpath=C:\ora_program\sqlj\lib\translator.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime12.zip;
SET classpath=C:\ora_program\jdbc\lib\classes12.zip;
The code of my program is:
import java.sql.Date;
import java.sql.SQLException;
import oracle.sqlj.runtime.Oracle;
import java.util.Date;
public class Hello{
     public static void main(String[] args){
          java.sql.Date current_date;
          try{
               // connect to the db
               Oracle.connect(
                    "C:\ora_program\bin",
                    "system",
                    "manager");
               // get the current date from the database
               #sql{SELECT sysdate INTO :current_date FROM dual};
               // display message
               System.out.println("Hello, the current date is: "+ current_date);
          catch(SQLException e){
               System.err.println("sqlException: "+e);
          finally{
               try{
                    Oracle.close();
               catch(SQLException e){
                    System.err.println("sqlException: "+e);
And then I compile my program in DOS with the typing: sqlj Hello.sqlj
The program cannot be compiled and the error message is:
"Exception in thread main java.lang.NoClassDefFoundError: sqlj/tools/Sqlj"
It indicates that the SQLJ translator class files cannot be found.
I have set up the classpath in DOS (see above). How does the error come? Please help. Thanks.

SET classpath=C:\ora_program\sqlj\lib\translator.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime.zip;
SET classpath=C:\ora_program\sqlj\lib\runtime12.zip;
SET classpath=C:\ora_program\jdbc\lib\classes12.zip;
The above only sets the classpath to the last value. You need to use the following.
SET classpath=%classpath%;C:\ora_program\sqlj\lib\runtime.zip;
