Module Processing :

Question

Hi All
I have a scenario where I am picking up a set of files using the File Adapter Sender. The polling is set to 60 seconds and the processing paramerter are EOIO. I have a bean in place to convert the file so picked up into Base64.
What I see happen is that the Bean is returning the same converted string for more then a couple of messages ie.
File1 -> Bean Conversion -> File1 Converted Message
File2 -> Bean Conversion -> File1 Converted Message
File3 -> Bean Conversion -> File1 Converted Message
In the later two cases it should have returned
File2 Converted Message
File3 Converted Message
Why is this happening ? How can I trace this to see what is wrong. Isnt the Module context and Module Data supposed to change with each case.
Here is the code in my Bean
package mckpedBase64;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import javax.ejb.CreateException;
import com.sap.aii.af.mp.module.*;
import com.sap.aii.af.ra.ms.api.*;
import com.sap.aii.utilxi.base64.api.Base64;
@ejbHome <{mckpedBase64.ConvertoBase64Home}>
@ejbLocal <{mckpedBase64.ConvertoBase64Local}>
@ejbLocalHome <{mckpedBase64.ConvertoBase64LocalHome}>
@ejbRemote <{mckpedBase64.ConvertoBase64}>
@stateless
@transactionType Container
public class ConvertoBase64Bean implements SessionBean, Module {
     public void ejbRemove() {
     public void ejbActivate() {
     public void ejbPassivate() {
     public void setSessionContext(SessionContext context) {
          myContext = context;
     private SessionContext myContext;
Business Method.
     public ModuleData process(
          ModuleContext modulecontext,
          ModuleData inputModuleData) {
          try{
          Object obj = null;
          Message msg = null;
          XMLPayload xmlpayload = null;
          String str_b64 = " ";
          String xmldata = " ";
          obj = inputModuleData.getPrincipalData();
          msg = (Message) obj;
          //Payload payload = msg.getDocument();
          xmlpayload = msg.getDocument();
            str_b64 = com.sap.aii.utilxi.base64.api.Base64.encode(xmlpayload.getContent());
          xmldata =
               "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n\n"
                    + "<ns:"
                    + "MC_SOAPFile_mt"
                    + " xmlns:ns=\""
                    + "http:/MCK_FILERFCSOAPRFC.COM"
                    + "\">\n"
                    + "<MCREQ>"
                    + str_b64
                    + "</MCREQ>\n"
                    + "</ns:"
                    + "MC_SOAPFile_mt"
                    + ">";
          xmlpayload.setContent(xmldata.getBytes());
          inputModuleData.setPrincipalData(msg);
          } catch (Exception e) {}
               //System.out.print(e.getMessage());}
          return inputModuleData;
Create Method.
     public void ejbCreate() throws CreateException {

Hi Aju,
>>Isnt the Module context and Module Data supposed to change with each case.
Yes, these objects will change with each incoming data.
Comment this line of code and try...
inputModuleData.setPrincipalData(msg);
>>How can I trace this to see what is wrong.
You can trace the messages inside the process method by writing them into a file using the following code...
File f = new File("d:
testing.txt");
FileOutputStream fos = new FileOutputStream(f);
PrintStream ps = new PrintStream(fos);
ps.println("Testing");
and finally close the file fos.close();
