Dear:
Now I need to send mutiple attachments by WMB. I choose the JMS as application client and transfer the attachments to bytes . But I don't know how to split the bytes on Compute Node.
In my message flow, the input node is MQInput, and the output node is SoapRequest. And the SoapRequest Node need multiple attachments exist as
byte[] .
What will I do? Do I need to use the FTE(File Transfer Editon)? Or any other suggestions for sending mutiple attachments for one output node. And the JMS is better. |

Hello.
If you use 7.0.0.1 or 7.0.0.2 the SOAP Request node itself can send SOAP with Attachment messages (SwA) with as many attachments as you like over HTTP or JMS transports. Simply use the SOAP Parser to build the SwA message. See the infocenter for more details...
Kind regards,

Hi, Thanks for your reply.
Actually, I don't know what I will do if one message contain two types of data by JMS,such as bytes and string.
Now I transfer the string message to bytes and combine with the former bytes. But I have no idea how to split them back to their own through WMB.
Any suggestion?
I use the method named writebytes() and writeUTF() of JMS BytesMessage(Java Class).
But the two bytes will be in one message. |

| You could change the bytes to string, using BASE64. |

The SOAP/JMS Spec supported by WMB only allows either a Text message or a Bytes message. And if it is a Bytes message it must be entirely written with writeBytes and the broker will receive it with readBytes only.

Assuming the bytes parameter name is "outs", I use the following method:
outs.toString(). But the outs will be changed into the string format, and the original format will lose.
How about your method?
Could you give me the Java method for transferring the bytes to string? And I can get back the format of the bytes in Compute node?
Thanks very much! |

Thanks . But if the bytes contain two parts, how I will split them by ESQL?
Any advices? |

You should, in general, never use writeUTF anyway. Instead you should use writeString with a properly formatted UTF string as the source.
You should, in general, when trying to figure out how to process a message in broker - using either Java or ESQL - use a Trace node to give you an output that shows what the structure of the message you are receiving IS.
Then you can figure out how to write ESQL or Java code to transform that message according to your requirements.
Nobody has nearly enough information about your problem - other than you - to answer "how to split it with ESQL". |

Is is a SOAP (with attachments?) message? If it is, the the SOAPRequest node will split it for you automatically. If it is not a SOAP message then you cannot use the SOAP request node at all and you will have to use the JMS nodes...
