Pass input thru Java and get output in Java

I have written a code which writes the hard coded data on to the commarea.

I tried invoking this prog thru Java. We pass input thru Java and get output in Java.

The string ‘ABCDEabcde12345AAAAAAAAAAAAAAAAAAAAAAAAA' is the output of CICS prog.

But while reading thru Java this is being displayed as ?cdeµ¥þ©§¹ùúÿ?????????????????????????

Let me know if any solution.

Sounds like a code page translation error, if the CICS is on the mainframe, where is the JAVA?

I could not understand what you are asking...can you tell me what is this code page trnaslation error and how it can be resolved?

well, lets start with this. Java only deals with unicode. CICS only deals with ebcdic. Unless you have designated otherwise, what CICS generated gets sent to the JAVA program. Between the two, you need to tell the interface software ('twn CICS and JAVA) that you need to convert the data.

i have checked there is no such interface issue....like what we are doing is we are just har coding it into the code just to check the pgm.....can you tell me how to trace the fault in the code....???

What is the middle ware u are using to connect JAVA to CICS?

I am not using any middleware as such....i am using ECI ( External Call Interface)

Hello,

The java is running on a desktop, correct?

I suspect that what has happened is that the transfer from CICS to java was done as a binary transfer - it needs to be an ascii transfer.

i think you are using ECI request CTG base class to interface to CICS.
First you need to pass the exact length of the commarea in your string. The cobol/CICS program and your java code should have the same length.
You need to do conversion in java .
byte commarea[] = ("----").getBytes("IBM037");
when u pass it to the commarea you have to conversion and the same way when u get the value returned from cobol to java also you have to do the conversion.
Hope this works...
the sample code
mport 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[] = ("----").getBytes("IBM037");
ECIRequest req= new ECIRequest(ECIRequest.ECI_SYNC,"CICS1","dsrm022","password","m22ap03","m22c",commarea,4,
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());
}
}
}
