want to return a compiled package binary based on certain
criteria or you want to return individual assets based on
certain criteria? </span><br>
</div>
The main objective is the first one : get compiled package
including filtred assert on certain criteria<br>
But if I can do the second (get all assets having certain
criteria), I can compile it myself.<br>
<br>
<div style="margin-left: 40px;"> <span style="font-style:

REST API (to be precise, it is the new JAX-RS based REST
api). In this case, you dont provide filters through the
URL. When you hit the REST URL for example </span><a
moz-do-not-send="true" style="font-style: italic;"
class="moz-txt-link-freetext"
href="http://localhost:8080/drools-guvnor/rest/packages/mortgage"
target="_blank">http://localhost:8080/drools-guvnor/rest/packages/mortgage</a><span
style="font-style: italic;">, the REST service will first
check if this package's binary is up-to-date. If not, it
will build the package first, then return compiled binary.
It is the Guvnor selector in charge of which assets get into
the build. At the moment, we dont have a REST API to control
which selector is taking effect during the build, but if
this is what you need, I am sure we can figure this out.</span><br>
</div>
It is exactly that : be able to choose the filter used to
compile the package.<br>

<br>
<div style="margin-left: 40px;"><span style="font-style:

you can send a HTTP GET request to URL </span><a

The links you provide and these sample seems really great to
access some internal values of repository, and even do updates
to programmatically ... but ... I can't get it work ... may be I
hit my limits on web-base things here ... So lots of questions :<br>
- I don't understand when you say "with
Accept="application/atom+xml" : what is "with" ? URL parameters
like <a moz-do-not-send="true" class="jive-link-wiki-small"
href="http://community.jboss.org/docs/DOC-16217"
target="_blank">http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets</a>?Accept="application/atom+xml"
? Guess not according to what you say after. So what is "with",
how do you provide these args to the URL ?<br>

In your case the URL should be <a moz-do-not-send="true"
href="about:blank">http://localhost:8080/drools-5.2.0.M1-guvnor/rest/packages/mortgages/assets</a><br>
The new JAX-Rs based REST interface is available from 5.2.0.M1. The
URL starts with <a moz-do-not-send="true" href="about:blank">http://localhost:8080/drools-5.2.0.M1-guvnor/org.drools.guvnor.Guvnor/api/</a>
etc is the old non-Jax-RS based implementation and will be
deprecated later. <br>

I noticed a <span style="font-family: Courier

but empty ... and I explicitely set some metadata in that rule
in guvnor before query it. What should go there ? Annotations ?<br>
<br>
<div style="margin-left: 40px; font-style: italic;">JAX-RS does
support query using URL like <a moz-do-not-send="true"
class="jive-link-wiki-small"
href="http://community.jboss.org/docs/DOC-16217"
target="_blank">http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets</a>?category=foo&category=bar&status=prod
(and several other query mechanisms). But we have not
implemented query in Guvnor yet. Of course you will be very
welcome if you want to help ;-)<br>
</div>
Yep why not ... if you don't find my previous questions too
stupid :)<br>
For now we will try to make the business user arrange their
rules directly in different packages and then query the package
"as usual" for each rule app we have<br>
But it is quite sure that this won't fit their needs in a real
living application where rules numbers will grow .... as for
rule apps<br>
<br>
Thanks a lot for you time anyway</div>
