JMS BC BytesMessage in BPEL

[kmo]

Hi there,

From a BPEL process , I want to send a BytesMessage to a JavaMQ queue.
The concrete WSDL that I generated expects a xsd:base64Binary type for the part.

In the BPEL mapper I noticed there is a "cast to" option that opens a SubType Chooser window that contains a base64Binary element, but I am not able to choose it (the OK button stays grayed out ???).
 
Is there another way (maybe directly in the source) to convert a String to this base64Binary type ?
Calling an external jar is imo not an option since the return type can only be String, Number , Boolean or Node.

I am using JavaCAPS 6 Update 1

Thanks
 
Kris

Hi,
It looks like you are looking for a conversion of xsd:string to xsd:base64Binary, currently there is no direct support for it.
Although i have not tired it, i think you could achieve it by calling a java function that takes the string as the input parameter and returns a string that is base64Binary (encoded), the conversion being done in the function. You could then assign that to your base64Binary node in your assignment.

Another link that maybe helpful, is this one on handling binary attachments in BPEL : http://wiki.open-esb.java.net/Wiki.jsp?page=BPELSEInlineAttachment

Please file an enhancement bug in issue tracker, https://open-esb.dev.java.net/IssueTracker.html, so that this can be considered for the next round of enhancement .

Thanks Philip,

in the meantime I tested with sending a base64 endcoded payload, which succeeded.
Because sending BytesMessages through the JMS BC requires base64 encoding, it would be nice to have some conversion available inside the mapper. I filed the enhancement for this.

Cheers,

What happened with this enhancement? Is it implemented yet?
