[rules-users] Guvnor Integration with Eclipse Issue !!

[abhinay_agarwal]

hey der !

m currently using GUVNOR v5.3.0

i made some DRLs in my Eclipse loaded them to Guvnor repository and after
loads of changes..i was finally able to build my kbase using the repositoy..

my change set is as foolows :

*<?xml version="1.0" encoding="UTF-8"?>
<change-set xmlns='http://drools.org/drools-5.0/change-set'
            xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
            xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'
>
    <add>
        <resource source='
http://localhost:8089/drools-guvnor/org.drools.guvnor.Guvnor/package/Individual/LATEST.drl'
type='DRL' />
    </add>
</change-set>*


My package name was Individual and it mainly contained technical rule
assests and one function, as shown in the image below :
http://drools.46999.n3.nabble.com/file/n4018919/drools1.png 

now i had a few changes in my POJO model so i updated the model and few
rules directly in the technical rule assest of guvnor, after which i built
the package created a new snapshot and tried running it, but got some error,
as :

1. Unable to Analyse Expression @Modify with($a){setExempt("Exempt
Account"),setQueueName("Auto Classified Accounts")};

2. KnowledgeAgent exception while trying to deserialize
KnowledgeDefinitionsPackage  

After going through all the available post, nothing proved to be of any help
!!


Then i thought might be changing the "technical assest" directly from guvnor
is a bad idea...

So, i created a new package named "Individual_New", uploaded the new POJO
model and uploaded just one rule from ECLIPSE(just to check if my kbase
builds or not)..

I uploaded just 1 rule in it, build the package and created a snapshot with
name LATEST, changed the change set as below:

*<?xml version="1.0" encoding="UTF-8"?>
<change-set xmlns='http://drools.org/drools-5.0/change-set'
            xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
            xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'

type='DRL' />
    </add>
</change-set>*

n now when i tried running it, it threw me the following error :
