Included #sql context DB1Ctx; did not create .class file

Question

Hello,
Request explanations on why this does not create a
SQLJTst3.class file? I type in sqlj SQLJTst3.sqlj
This creates the SQLJTst3.java and the .ser profile files but
no .class file.
My set-up is:
Oracle SQLJ Release 8.1.7.0.0 Production
Build version: 2.0.0.0 - Built on May 31, 2000
IDE interface version: 8.1.7.0.0/2.0.0.0
JDBC version: Oracle JDBC driver version 8.1 (8.1.7.0.0)
SQLJ runtime: Oracle 8.1.7 for JDBC 8.1.7 or later/JDK 12EE -
Built on Aug 18, 2000
Java version: 1.3 (1.3.0)
import sqlj.runtime.*;
import sqlj.runtime.ref.*;
import java.sql.*;
import sqlj.runtime.ref.DefaultContext;
#sql context DB1Ctx; // Define connection context
#sql context DB2Ctx;
public class SQLJTst3 {
public static void main(String[] args) {
Connection c = null;
String URL = "jdbc:oracle:thin:@gnj:1521:oralin";
String userid = "scott";
String passwd = "tiger";
try {                
DriverManager.registerDriver(new
Oracle.jdbc.driver.OracleDriver() );
// Connect to multiple databases
DB1Ctx dB1 = new DB1Ctx(DriverManager.getConnection(URL,
userid, passwd));
DB2Ctx dB2 = new DB1Ctx(DriverManager.getConnection(URL,
userid, passwd));
// Select a row from database DB1
String dBuser1;
#sql [dB1] { select user into :dBuser1 from dual };
System.out.println("Database username is " + dBuser1);
// Select a row from database DB2
String dBuser2;
#sql [dB2] { select user into :dBuser2 from dual };
System.out.println("Database username is " + dBuser2);
// Close the database connection
#sql { rollback work };
c.close();
System.out.println("Disconected...");
} catch (SQLException e) {
e.printStackTrace();
YET this one creates all the files and I can then java SQLJTst2.
import sqlj.runtime.*;
import sqlj.runtime.ref.*;
import java.sql.*;
// Iterators must be delared on top - sqlj will create classes
for them
#sql iterator TabIter (String, String);
public class SQLJTst2 {
public static void main(String[] args) {
Connection c = null;
String URL = "jdbc:oracle:thin:@gnj:1521:oralin";
String userid = "scott";
String passwd = "tiger";
try {
DriverManager.registerDriver(new
oracle.jdbc.driver.OracleDriver());
c = DriverManager.getConnection(URL, userid, passwd);
System.out.println("Successfully conencted to Oracle...");
// You need to set a Context for SQLJ, otherwise -
// SQLException: found null connection context
DefaultContext.setDefaultContext( new DefaultContext(c));
// Fetch multiple values
TabIter tabIter;
#sql tabIter = { select tname, tabtype from tab };
while (true) {
String dBTabName = null;
String dBTabType = null;
#sql { fetch :tabIter into :dBTabName, :dBTabType };
if ( tabIter.endFetch() ) break;
System.out.println("Name: " + dBTabType + "." +
dBTabName);
// Close the database connection
#sql { commit work };
#sql { rollback work };
c.close();
System.out.println("1..2..3..Disconected...");
} catch (SQLException e) {
e.printStackTrace();

Disgregard previous posting...I found the typo. It does create
the .class files now.
However the problem im getting this time is
Database username is SCOTT
Database username is SCOTT
java.sql.SQLException: found null connection context

It does not like two sessions from same user?
