Error in solving MultiSchema.sqlj

Question

Hello there,
I am trying to solve Multischema.sqlj example given in sample
examples of sqlj with slight moditications. My emp table is
having scott schema and dept table is having sheetal schema.
The compilation fails at
#sql (deptCtx) {
SELECT dname INTO :dname FROM sdept WHERE deptno = :deptno
stating error as "missing equal to sign".
can anybody help me to come out of this mess?
A complete program is as follows :
import java.sql.SQLException;
import java.sql.DriverManager;
import java.sql.Driver;
import java.sql.Connection;
// declare a new context class for obtaining departments
#sql context DeptContext;
#sql iterator Employees (String ename, int deptno);
class MultiSchema
public static void main(String[] args) throws SQLException
// Create the default context used to query employees.
ConnectionManager.initContext();
// Create a context for querying department info using
// a second connection. Edit the URL2, UID2, and PWD2
// strings for a connection and schema available to you.
String DRIVER = "oracle.jdbc.driver.OracleDriver";
String URL2 = "jdbc:oracle:thin:@garuda:1521:orcl";
String UID2 = "sheetal";
String PWD2 = "sheetal";
Boolean flg = false ;
Connection conn = null;
try {
Driver d = (Driver) (Class.forName(DRIVER).newInstance());
DriverManager.registerDriver(d);
} catch (Exception ex) {
System.err.println("Could not load driver: " + DRIVER);
ex.printStackTrace();
System.exit(1);
try {
conn = DriverManager.getConnection(URL2, UID2, PWD2, flg);
} catch (SQLException ex) {
System.err.println("Could not get another connection");
ex.printStackTrace();
System.exit(1);
DeptContext deptCtx = new DeptContext(conn);
new MultiSchema().printEmployees(deptCtx);
deptCtx.close();
// Performs a join on deptno field of two tables accessed from
// different connections.
void printEmployees(DeptContext deptCtx) throws SQLException
// obtain the employees from the default context
Employees emps;
#sql emps = { SELECT ename, deptno FROM emp };
// For each employee, obtain the department name
// using the dept table connection context.
while (emps.next()) {
String dname;
int deptno = emps.deptno();
#sql (deptCtx) {
SELECT dname INTO :dname FROM sdept WHERE deptno = :deptno
}; // I GET AN ERROR HERE as MISSING EQUAL SIGN IN
ASSIGNMENT
System.out.println("employee: " emps.ename()",department:"
+ dname);
emps.close();
thanking you in advance,

Are you using JDK 1.2.1? If yes, then try to use JDK 1.2.2 instead. We have seen JDK 1.2.1 garbage collecting things that are still in scope (very unsafe).
If wiggling your configuration does not help, you'll need to provide more info about your environment and it would be best to get a reproducible test case.
One other note: make sure to finally close the SQLJ iterator not the result set that is being returned. Otherwise you can start leaking cursor handles and/or statement cleanup will not be properly performed.
