Stateful session and non-existence of Facts
by Leonardo Gomes
Hi Guys,
I have the following situation while running a stateful session with Drools
4.0.7:
- I want to test that a fact with a given state doesn't exist;
- It works fine
- At a certain point I have to retract all facts and reinsert them at the
stateful session - some of them actually changed and I don't want to
recreate the session b/c it's expensive
- Again the fact that didn't exist when I first created the session still
doesn't exist
** Problem: This time the rule that verified the non-existence is not fired
because I didn't insert any fact that would retrigger it.
Rule example:
rule "022"
when
SiteLanguage(language : languageCode)
t : SiteSpecialServiceType(type : specialServiceType)
not SiteLanguageSpecialServiceType(specialServiceType == type, languageCode
== language)
then
<<consequence>>
end
How could I solve or workaround that?
Thanks in advance,
Leo.

Server Compatibility of Drools
by ramram
Hi All,
I am currently using the Drools Flow with the GWT web console and I could
create many rule flow processes using the JBOSS 4.2.3 version.
But what I am concerned about is that there will be problems if I changed
the application server?
Please can you help me and tell me if the Drools Flow and GWT web console
are compatible with the following application servers:
1- OC4J
2- Bea Weblogic 9.0
3- IBM Websphere
4- Tomcat 6.0

Drools Flow Scheduler?
by stevelaw
I would like to begin a rule flow process at 16:00 M-F, and possibly skipping
specific holiday's as well. Is there any built in capability in Drools
Flow, or should I use an external scheduler such as Quartz, etc? I'm
assuming an external scheduler is the recommended way. If so, are there any
examples?
Thanks

Problem in Building of default package in the GUVNOR
by ramram8
Hi all,
I have the following problem:
1- I am uploading a rule file into the guvnor the file can be uploaded
successfully
2- When I go to the default package and I press save and validate there is
no error and all is fine till here
3- When I build the package I am having the following exception:
Rule Compilation Error the decleraed package "" doesnt match the
expected
and unable to generate rule invoker
After tracing it I find that it is resulting from the following:
I have in my Rule Flow that is being uploaded a split in the split there is
the following
<split id="5" name="Gateway" x="329" y="160" width="49" height="49"
type="2" >
<constraints>
<constraint toNodeId="13" name="End Process" priority="2"
type="code" dialect="java" >return endProcess;</constraint>
<constraint toNodeId="3" name="Create User" priority="1" type="code"
dialect="java" >return createUser;</constraint>
</constraints>
</split>
If I removed the type="code" from the constraint tag the process could be
uploaded successfully
BUT I am facing after this an error in the GWT I dont know if it is because
I have removed the type="code"
How I can fix this issue??
Is the problem from the Guvnor or from my Rule Flow file??
Please to help in this issue
the Execption is :

Server Compatibility of Drools
by ramram8
Hi All,
I am currently using the Drools Flow with the GWT web console and I could
create many rule flow processes using the JBOSS 4.2.3 version.
But what I am concerned about is that there will be problems if I changed
the application server?
Please can you help me and tell me if the Drools Flow and GWT web console
are compatible with the following application servers:
1- OC4J
2- Bea Weblogic 9.0
3- IBM Websphere
4- Tomcat 6.0
