Hi,

Thanks for the update, I'll add it to the next release so that we can
support jbi operations.

Re: [Bpmscript-users] Release schedule

[dkfn <jam...@gm...>]

Hi,

Currently there's no release schedule as yet. I'm busy working on moving
bpmscript to maven 2 to match with servicemix as it makes dependency
management simpler. I'm also moving to hibernate for process / correllation
and perhaps task persistence. Once that's done, bpmscript will be feature
complete for version 1 (once the bugs have gone too).

processes will definitely be service units. they can be now but there's
little documentation.

cheers,
j.

[Bpmscript-users] jbi operation parameter required

[jpangburn <jes...@qu...>]

Hi,
This is a suggestion more than a question. =20

In regards to JBI integration, many JBI services require that you specify
the "operation" to the service that you are invoking.  For example, invokin=
g
a BPEL service always requires the operation to be specified.  The current
version of the send function only has the following parameters: namespace,
localPart, service, message, properties.  I tried setting an "operation" an=
d
then an "Operation" property, and these were properly set as properties of
the jbi message, but the message's operation field remained null.  I
resolved this problem by modifying the send function to look like this:
this.send =3D function(namespace, localPart, service, message, properties,
operation) {
=09return this.sendTemplate(namespace, localPart, service, function(inOut) =
{
=09=09if(operation !=3D null) {
=09=09=09inOut.setOperation(operation);
=09=09}
=09=09var inMessage =3D inOut.createMessage();
=09=09if(properties !=3D null) {
=09=09=09for(var property in properties) {
=09=09=09=09inMessage.setProperty(property, properties[property]);
=09=09=09}
=09=09}
=09=09if(message !=3D null) {
=09=09=09inMessage.setContent(message);
=09=09}
=09=09inOut.setInMessage(inMessage);
  =09});
  };

This creates an optional "operation" field which sets the MessageExchange's
operation field.  The operation field is actually a QName, so here's a
sample process definition to invoke it:
function main(input, sender) {

=09var qname =3D new Packages.javax.xml.namespace.QName("urn:/HelloWorld2.w=
sdl",
"Hello");
    // send a message to the BPEL component=E2=80=99s HelloService service
    var future =3D sender.send("urn:/HelloWorld2.wsdl",=20
       "HelloService", true,
       input.getInMessage().getContent(), null, qname);
   =20
    // get the result from the future
    var exchange =3D future.get();

    // echo the reply to the calling component
    sender.reply(exchange.getOutMessage().getContent());

}

You'll note that I created a Java QName object to pass, though it might be
nice to modify the send function to take a string representation instead
(e.g. "{urn:/HelloWorld2.wsdl}Hello") and parse that into a real QName
object.  Also, I passed null for properties so I could get to the operation
parameter.  Depending on how much others agree that's required, perhaps
operation should come before the properties to avoid the need for always
passing that null parameter.

[Bpmscript-users] Release schedule

[qxcfg <hc...@ya...>]

Hi,

   Right now this is Beta1. Do you plan on having a few other Beta's and
what are the rough dates for them and maybe the final release?

   One question about process creation. Do you plan on making a process a
JBI service unit so it could be managed via the JBI lifecycle interfaces
(and perhaps facilitate tools development like an IDE, debugger etc)

Thanks!

Re: [Bpmscript-users] user admin

[dkfn <jam...@gm...>]

Hiya,

You've noticed correctly. The scope is cached with the process rather than
the process instance id. It's a performance trade-off and I do need to
document it better. I'd certainly intended to make it configurable (there's
a cacheScope field but I haven't put a setter onto it, yet) but basically,
it would be bad (as in "don't cross the streams") to use process global
variables by just putting them at the top level scope of the script. None of
the examples do but it's definitely not clear enough. The justification is:

* For most things, you shouldn't need to use process global variables
* It's _way_ faster

cheers,
j.

Great! thanks.
While I am at this, may I post another question. I was reading source code
from cvs and down there in processExecutor, in the getScopeCached method,
the scope seems to be cached with process id rather than process instance
id. Does this mean that you can only have one process instance running at
the same time? otherwise how do you prevent the multiple instances from
using the same scope and polluting it? or is this something the Rhino does
internally?

Thanks.

Re: [Bpmscript-users] user admin

[dkfn <jam...@gm...>]

BpmScript uses Acegi for it's user management. Currently it just points to an
inmemory set of user names and passwords set up in the spring
applicationContext. You should be able to configure it to point to most
security stores by changing that config.

It would be very nice if there was an option to add expiration timer to

taskRequest.response("rocks", "Rocks!");
taskRequest.setRole("ANONYMOUS");

var expirationDate = new Date();
expirationDate.setFullYear(2006,9,14);

As we discussed, bpmscript can be deployed as a standalone Servicemix JBI

Hiya,

Sorry I missed this, I thought Nabble would automatically forward to the

At the moment the web console doesn't allow the setting of message
properties. I'll look into adding it for the loan broker example. Either
that or I'll change the loanbroker so that it can pull the parameters out of
the incoming XML.

I would like to use the loanbroker process from the Web Console by sending a

But when calling the loanbroker process from the Web Console, is there a way

Thank you.
