Re: [rules-users] Guvnor service to compile part of a package ?

I am not sure if I understand you correctly. You want to return a compiled package binary based on certain criteria or you want to return individual assets based on certain criteria? The main objective is the first one : get compiled package including filtred assert on certain criteria But if I can do the second (get all assets having certain criteria), I can compile it myself . If its the former, you can do this through Guvnor 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 http://localhost:8080/drools-guvnor/rest/packages/mortgage , 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. It is exactly that : be able to choose the filter used to compile the package. If what you want is to return individual assets, you can send a HTTP GET request to URL http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets with Accept="application/atom+xml", this returns a list of assets under the mortgage package in Atom feed format. ... For example a GET request to http://host:portnumber/ drools-guvnor/rest /packages/mortgage/assets /testAsset1 with Accept="application/atom+xml" returns an atom entry which is the meta data info of that asset. 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 : - I don't understand when you say "with Accept="application/atom+xml" : what is "with" ? URL parameters like http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets ?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 ? - when I try the URL given "as this" ( http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets ) tomcat replies that there is no service. I get something to work with this URL http://localhost:8080/drools-5.2.0.M1-guvnor/org.drools.guvnor.Guvnor/api... , ie adding "org.drools.guvnor.Guvnor", with "api" instead of "rest", and without "assets" (which tells me that the "assets" is not a valid path). Does this mean that I am not running the correct version ? Need to deploy something else ? Need to configure something ? - with my URL form, I can get the content of a package (raw text, one resource by line) like this : drools.package=2008-09-30T03:36:29,1 MortgageModel.model.drl=2008-10-22T22:01:14,6 Underage.brl=2008-10-01T04:54:34,2 ... - or one rule (http://localhost:8080/drools-5.2.0.M1-guvnor/org.drools.guvnor.Guvnor/api...) : <rule> <name>RegexDslRule</name> <modelVersion>1.0</modelVersion> <attributes/> <metadataList/> <lhs> <dslSentence> <sentence>When the ages is less than {57:1?[0-9]?[0-9]}</sentence> </dslSentence> </lhs> <rhs/> </rule> I noticed a metadataList there, but empty ... and I explicitely set some metadata in that rule in guvnor before query it. What should go there ? Annotations ? JAX-RS does support query using URL like http://host:portnumber/drools-guvnor/rest/packages/mortgage/assets ?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 ;-) Yep why not ... if you don't find my previous questions too stupid :) 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 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 Thanks a lot for you time anyway
