12:23 p.m.
I'm running CR1 (Guvnor and exec server) on Tomcat (tried v 5XX and 6XX)
I've tried this with the mortgage package and then went simpler, I'm
getting the same error.
The package now has one rule:
when
eval(true)
then
System.out.println("It works");
Compiles fine on govner, etc.
My rule agent configuration is:
newInstance=true
#file=/foo/bar/boo.pkg /foo/bar/boo2.pkg
#dir=/my/dir
url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/foo/test
#localCacheDir=/foo/bar/cache
poll=30
name=MyConfig
When I post to the url (via poster in firefox) I get:

From the error message it looks like the XML you are sending to
execution
server is not correct.
I have the same configuration - tomcat6 (works on both ubuntu and windows)
with guvnor and execution server. I use the rule agent configuration file
with just two params url and poll and it works fine. Note that the url has
to point to the snapshot you created in guvnor for your package. The name of
the configuration file say FooRules.properties should be used in the request
as
/drools-server/knowledgebase/FooRules
and the FooRules.properties file has to be placed in the WEB-INF/classes
directory of the execution server.
Instead of sending XML I am currently sending it JSON using ruby and it
works beautifully.

I think the rule agent config is ok - if you have a mangled prop file the
execution server tells you that, and the log file seems to indicate it was
loaded ok. It seems like execution server pulles the rules package across
and transforms it into xml for the response?, and this is my guess where it
is going wrong.
I also tried it using the file setting vs. the url. Oh, and I'm on Suse 10.3
and jdk 1.5 and 5 (I tried it with both). I also tried JSON to see if that
helps but no go.
