Module Processing :

[Former Member]

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();

Hi All

After a lot of effort I found out that the issue is the statement

str_b64 = com.sap.aii.utilxi.base64.api.Base64.encode(xmlpayload.getContent());

code.

It looks like the static method is only returing the result of the first conversion. Even if it is called multiple times with different xmlpayloads !

Any thoughts ?

Aju-

How are you referencing the com.sap.aii.utilxi.base64.api.Base64.encode class in your EJB? If you have included the JAR in your EAR, open your EAR using WINZIP and delete the 'JAR'.

Hard reference this class in your J2EEConfig and deploy the 'EAR' again.

Let me know if this works.

Hi KK

No the com.sap.aii.utilxi.base64.api.Base64.encode

Is not included as the jar in the EAR

Hi Aju,

have you tried using the class sun.misc.BASE64Encoder for your base 64 encoding?

You can use it like this:

BASE64Encoder encoder = new BASE64Encoder();
String enc = encoder.encodeBuffer(byteArray); 

I know it's not an offical java class, but it works... hopefully

Matthias

Hi Aju,

Does that file get deleted after it gets picked up from the folder? Is your adapter in the test/delete mode?? Also check if the second file's payload can be seen in sxmb_moni..

Jusr try the delete mode and if you donot want the file to be rmoved altogether, archive the file which is already picked up.

Hi Sushumma

Yes, its on archive mode. I have also checked the messages in MONI. The message picked in the Bean is the right one. Only when I make the call for the Base64 call, does it start behaving weird.

Its looks like the static method is doing something or ts getting stuck somewhere between the Module Processor and the AE

Hi Aju,

Do a cache refresh and then try again...

also, are you archiving the file to another folder/or into the same folder again? Check how the getDocument() method is picking the file exactly?
