Thanks for listening. seems as soon as I post I find my own answer

stEvent = new BrokerEvent(null,"wm::is::Samples::SampleStruct)

<doh>

Now I can publish the document, but if I look at the data in the pipeline the data is not (IMO) correct
Pipleine in WmMonitor show ???
save Pipeline from Flow Service shows high-ascii data
Not my simple strings.

eventtype wm::is::Samples::StructDoc
{ unicode_string name;
struct
{ unicode_string element01;
unicode_string element02;
unicode_string element03; }
sampStruct; }
[…]
try
{
event.setStringField(“name”,“Name is Paul”);
stEvent.setStringField(“element01”,“Name is Paul”);
stEvent.setStringField(“element02”,“e02Val”);
stEvent.setStringField(“element03”,“e03Val”);
event.setStructFieldFromEvent(“sampStruct”,stEvent);
}
[…]

see attachment for pipeline

I put some output into the client
to getStructFieldAsEvent on the sampStruct I just built.
and I can get it back populated
System.out.println("sampStruct is "+event.getStructFieldAsEvent(“sampStruct”));

[…]
sampStruct is

event struct_value {
string element01 = “e01Val”;
string element02 = “e02Val”;
string element03 = “e03Val”;
};
[…]

Why cannot I not see this in the pipeline?

Got it.
Attached please find a sample java BrokerClient for a simple structured document and a java class to store the object.

Paul great job. thank you for posting the answer to your own question.
just want to say
while ()
{
thank you
}

Hi Paul
I’ve been trying to reproduce what you’ve done here on a concrete example.
But, in my case, “sampStruct” is a Struct array (Struct).
Furthermore, my IS document “sampStruct” has not been declared as publishable onto the broker.

So in my case, the line
“stEvent = new BrokerEvent(null,”<any>“,sampleMsgToPublish);” doesn’t seem to work out since “<any>” is not a valid reference to a document type declared on the broker.

I guess I have to make my doc “sampStruct” publishable in order to make it work correctly. I’ll try out …

Well, I’ve declared the sub-document as publishable (hopefully, it was a separate document and now it works fine.
So “<any>” can’t be “anything” like I thought, but a valid reference to a a declared doc onto the broker.
This is obvious because what if you want to fill in a document in a main document (that is, a sub-document), knowing that this subdocument is not a separate document? I guess you can’t …
