below i post my code :

import java.util.*;
import java.sql.*;
import java.io.*;
import com.hxtt.sql.*;

public class backofficeDbfVerification {

public backofficeDbfVerification(String path) throws SQLException {
Properties prop = new Properties();
prop.setProperty("user", "");
prop.setProperty("OtherExtensions","true");
prop.setProperty("Version Number", "03");
try {
Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();
connection = DriverManager.getConnection("jdbc:DBF:/"+path, prop);
}
catch (ClassNotFoundException classnotfoundexception) {
System.out.println("could ot find HXTT class, make sure the classpath have been defined in your system !");
}
catch(Exception e) {
System.out.println(e.getMessage());
}
}

public void createBadRecord(String table, String newtable, int blth) throws SQLException {
Statement stmt = connection.createStatement();
String insert = "insert into \""+newtable+"\" select * from \""+table+"\"";
boolean bInsert = stmt.execute(insert);
stmt.close();
}

public static void main (String args[]) {
String path = "C:\\MASTER\\SOURCEDATA\\AREA";
try {
backofficeDbfVerification test = new backofficeDbfVerification(path);
test.createBadRecord("source\\area\\123.AA2","source\\area\\others\\89964568.AA1");
}
catch(SQLException sqx) {
System.out.println("Error "+sqx.getMessage());
}
}
}

i try to perform simple query : insert into tablea select from tableb which has same structure. the source table has only 9 rows, but the process ran very long time, no error message raised,it just run and never end (which make me upset for the whole day).

is it becoz of function limitation since i used evaluation copy ?

No function limitation. I just tested:
create table testa1 select * from test;
insert into testa1 select * from test;

Passed.

I also run your backofficeDbfVerification.java sample. Passed too. I'm using the same code as you. The difference is only my 89964568.AA1 and 123.AA2 is simulative tables files. If possible, please zip your 89964568.AA1 and 123.AA2 and email to webmaster@hxtt.com. Thanks.

BTW, I pasted the little modified backofficeDbfVerification.java below:
import java.sql.*;
import java.util.*;

public class backofficeDbfVerification {
Connection connection;

public backofficeDbfVerification(String path) throws SQLException {
Properties prop = new Properties();
prop.setProperty("user", "");
prop.setProperty("OtherExtensions", "true");
prop.setProperty("Version Number", "03");
try {
Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();
connection = DriverManager.getConnection("jdbc:DBF:/" + path, prop);
}
catch (ClassNotFoundException classnotfoundexception) {
System.out.println("could ot find HXTT class, make sure the classpath have been defined in your system !");
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}

public void createBadRecord(String table, String newtable) throws
SQLException {
Statement stmt = connection.createStatement();
String insert = "insert into \"" + newtable + "\" select * from \"" +
table + "\"";
boolean bInsert = stmt.execute(insert);
stmt.close();
}

public static void main(String args[]) {
String path = "f:\\dbffiles";
try {
backofficeDbfVerification test = new backofficeDbfVerification(path);
test.createBadRecord("source\\area\\123.AA2",
"source\\area\\others\\89964568.AA1");
}
catch (SQLException sqx) {
System.out.println("Error " + sqx.getMessage());
}
}
}
