CTG ECI request - JAVA client program

Hi this is the code that i am using to communicate to CICS z/os server using the sample code - ECIRequest.
In the CICS TS v2.3 on Z/os the TCPIP listener program is active.
Network connection is working properly ...
when i run the java code i get a return code -27(which is security error) I am not sure whether it is happening in my windows environment or while communicating to z/os cics server.
The code is as follows?(please need your help where i am going wrong)import com.ibm.ctg.client.JavaGateway;
import com.ibm.ctg.client.*;
import java.io.*;
public class Comm
{
public static void main(String args[]) throws IOException
{
try
{
JavaGateway jg = new JavaGateway("localhost",2006);
byte commarea[] = ("abcd").getBytes("IBM037");
ECIRequest req= new ECIRequest(ECIRequest.ECI_SYNC,"CICS1",null,null,"m22ap03","m22c",commarea,100,
ECIRequest.ECI_NO_EXTEND,
ECIRequest.ECI_LUW_NEW);
System.out.println("Comm in: " + new String(req.Commarea, "IBM037"));
jg.flow(req);
System.out.println("Comm out: " + new String(req.Commarea, "IBM037"));
System.out.println("Rc: " + req.getRc());
jg.close();
}catch (IOException ioe) {
System.out.println("Handled exception: " + ioe.toString());
}
}

----I get return code -27

to determine if CICS security error, ask your techsupport. there should be a related security message coming from the CICS region.

or
try executing the CICS program from green screen 3270

Thanks earl
Thru telnet port 23 i am able to access my program.
When i try to access it from my java client program using CTG ECIRequest i am getting -27 error.
Which is a security error.
I need some help on understanding the getRC method???
Would like to know whether i have coded it properly.
I am new to JAVA, please some one help us solve this issue...

Thanks!

I am pointing to the correct CICS region.
The only thing i would like to know is do i have to have a webserver to run this java program.
Do i need to change any security settings in the z/os for the ecirequest???
Do i have to mirror the transaction names i use in the ECIREquest - in the CICS z/os
i really need to resolve this ----
thanks in advance

I don't understand your comment "mirror the transaction names"

Are you linking to a program that in turn is expected to execute
a CICS transaction ?

can you submit an http request from browser to invoke your program?
ask you systems people for correct syntext:::

Hi Nimesh

In the CICS region when they enabled the TCPIPSERVICE(ECI) the security is set to local.
so we are using the default user id and directly invoking the CICS Tranaction and program thru the ECIRequest.

Am i missing anything in my code.
Do i have to have an websphere application server on the windows...
I am totally lost ---

ramco_sita,
do one thing, from your CICS client on windows go to CICS terminal and login with a valid user id and initiate your transaction using EXEC CICS START TRAN. On the server-end see whether the transaction is initiated and has run. If yes, then code the same userid and password in your ECI request and test again, it should go through if its because of a userid security validation. If no, then you can ask your system people why is default userid / test userid not working.

Hope this helps
Nimesh
