[rules-users] Drools Execution Server and NoClassDefFound

[Régis Ramillien]

Hello,

I have a problem using execution server. It sends a NoClassDefFoundError.
I search for hours, but find nothing...

Why I have done, in guvnor:
I have created :
-- a package "com.myorg.myapp"
---- a declarative model "Model1"
------ with a fact "Fact1"
-------- with a text field "field1"
-------- with an integer field "field2"
---- a Business Rule "rule1"
------ which test for the "field1" value, and set the "field2" to a dummy
value.

I then created a snapshot called 'release'

I created a myappAgent.properties with the following values:
name=mrgAgent
newInstance=true
url=
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/com.myorg.myapp/release
poll=60
I put the file in drools-server classes directory

I then tried to call execution server using CURL:
curl --data "<knowledgebase-request><
inOutFacts><named-fact><id>Fact1</id><fact
class='com.myorg.myapp.Fact1'><field1>Any
response?</field1></fact></named-fact></inOutFacts></knowledgebase-request>"
http://localhost:8080/drools-server/knowledgebase/myappAgent

And the server (drools-server I assume, not guvnor ?), send me this
response:
...
ling this request.</u></p><p><b>exception</b>
