retrieving the attachment in the adapter module

[Former Member]

hi,

i have created an adapter module to retrieve the attachment payload. This module is placed after the Seeburger bic module chain. but everytime i execute the module i get null pointer exception.

i have used the following code to retrieve the attachment.

//code for retrieving the attachment

try {

Iterator itr = msg.getAttachmentIterator();

if (itr.hasNext()) {

while (itr.hasNext()) {

Payload attachment = (Payload) itr.next();

byte payLoadContent[] = null;

in_Data = attachment.getInputStream();

in_Data.read(payLoadContent);

attachmentContent = new String(payLoadContent);

break;

}

}

log(amkey, "The attachment " + attachmentContent, null);

} catch (Exception e) {

log(amkey, " Attachment not found ", e);

throw new ModuleException("Unable to retrieve the atachment payload"e"...exit module");

}

Please let me know how to resolve this error and also how can i retrieve the attachemnt payload.

Regards,

Meenakshi

Hi Meenakshi,

Are you using this module in the receiver communication channel? If yes then make sure you have checked the Read Attachments option in the operation mapping.

Hi

First check if there are any attachements using

int i = msg.countAttachments();

//then try out

Payload  p = msg.getAttachment();

HI,

Add trace in your module code for debugging purposes.

Please check J2EE logs so that you can trace where exactly the error is coming from....

hi,

Try using :

OutputMessage parseobj = new OutputMessage();

String content = content + parseobj.parseMessage(attachment.getInputStream());

Please check following blog:

Hi

Could you let me know exactly how to add trace to the module ? Is it done in the code or some other setting?
