Guvnor Error
by HonorGod
Hi,
I have uploaded decision tables into drools guvnor and the corresponding
model jar. I have the following in the decision table import section
Import com.barcap.efg.fine.util.LogUtil, java.util.Date
And in one of the actions I have
LogUtil.caRecommendationLogger.warn("Lift Rule Fired = "+11);
When I try to validate the decision table using Guvnor I get the following
error -
[Corporate_Actions_Update_Lift_dates] Rule Compilation error Only a type
can be imported. com.barcap.efg.fine.util.LogUtil resolves to a package
LogUtil.caRecommendationLogger cannot be resolved to a type
[Corporate_Actions_Update_Lift_dates] Rule Compilation error Only a type
can be imported. com.barcap.efg.fine.util.LogUtil resolves to a package
LogUtil.caRecommendationLogger cannot be resolved to a type
[Corporate_Actions_Update_Lift_dates] Rule Compilation error Only a type
can be imported. com.barcap.efg.fine.util.LogUtil resolves to a package
LogUtil.caRecommendationLogger cannot be resolved to a type
But the same works with no errors when I run my project through eclipse.
Please guide.
Thanks

how set breakpoints in 5.x process flows
by Chuck Irvine
Sorry if I'm missing the obvious. In the eclipse IDE, I can't figure out how
to set breakpoints in (5.x) flows. The documentation indicates that this is
supported, but I can't see any description of how to do it. Can anyone
help? Thanks -Chuck

Can we have two or more Changeset.xml file in an Application
by Pardeep Ruhil
Hi,
My doubt is, Can we have two or more changeset.xml file having different workflow, and any change in the workflow or rule will read the corresponding changeset.xml file and rebuild the knowledge base in an application.
Thanks & Regards
Pradeep Ruhil

Understanding "no viable alternative ..." errors
by Pritam
While executing the following rule,
rule "home dummy"
when
pointId: Point(page == "home", region ="center-content")
content: Content(id=="adslot")
properties["type"]=="ad" from content
then
filter.put(content.id, true);
end
I get the following error:
[ERR 101] Line 16:46 no viable alternative at input 'EQUALS' in rule "home
dummy" in pattern PointId[18,16]: [ERR 102] Line 18:16 mismatched input
'"type"' expecting ']' in rule "home dummy" in pattern properties
The documentation explains that this is the most common error but I still
struggle to understand the correct grammar for writing rules. Can anyone
point me to a good resource (I even read the book "drools 5) for writing the
following rule in a drl format?
" If a Point has a page, "home" and region, "center-content" and the Content
id is "adslot" with a property, type as "ad" then filter the Content (using
a global map and passing a boolean flag)
Thanks

Re: [rules-users] How to specify relative URL in chagenset.xml file
by Pardeep Ruhil
Hi Mark,
Thanks for answering my query.
It is picking the relative path now, provided there is no space(' ') in a folder name.
Is there a way, that it wil pick the folder having space in name ?
Thanks & Regards

If I told you that the above would do nothing more than:
new File ("../HelloWorld.drl");
Would that help?

drools 5.0.1 enum serialization/deserialization problem
by Garner, Shawn
We are pre-compiling the rules and then reading them in and running them later.
I'm getting this error when reading in the compiled (serialized rules) rules:
"Error deserializing enum value"...
This line (pretty similar to this) is causing the issue when it's deserializing the Java 5 Enum.
MyClass( myEnumType == MyEnum.MY_ENUM_VALUE)
I saw some bug reports that this is fixed in 5.0.2 but I can't find it and it's been a while since 5.0.1 was released.
When is this going to be fixed or is there a way to get a snapshot 5.0.2 with this fixed?
Can somebody help me?
Thanks,
SDG

Backing up Guvnor repository
by RichardA
Today we are using Drools 4 and the gui for the rules.
The backend of the gui repository is in Oracle, and we backup the oracle db
each day.
But we also perform an export from the gui using the import/export function
to gather a known good repository.
In drools 4 we can use:
wget -O repository_export.zip
http://localhost:4980/drools-gui/drools.../backup
and this does the same as the export...
but in guvnor we have enabled authentication, and when we run:
wget -O repository_export.zip
http://localhost:4980/guvnor/org.drools.guvnor.Guvnor/backup
we get Internal server error, exception shown below.
Is there a way to authenticate via a url call?
wget -O repository_export.zip
http://admin:passwd@localhost:4980/guvnor/org.drools.guvnor.Guvnor/backup
doesn't work.
Thanks
Ric

Hi ,
I’m writing to you for Packt Publishing, the publishers of computer
related books.
We are planning to publish a new book on Drools, titled, Drools
Developer Cookbook.While looking out for some potential authors to write
this book, I came across your profile and saw. that you were one of the
contributor and I also see that you write blogs on Drools.These give me
an impression that you could be a potential author for this book.
Written in a cookbook style, this book will be aimed at Java developers
who already have experience of working with Drools and would like to
learn how to do more stuff with it.
To give you an idea about the way things work at Packt:
-The editorial team at Packt works with the author throughout the project
-We pay a royalty of 16% and an advance against it.
-The marketing team at Packt ensures that the book is well promoted.
-In its ongoing commitment to Open Source, Packt donates a percentage of
revenue generated by the book to the OpenSource project on which it is
based. We have donated more than 100 000 dollars to various Open Source
projects since inception in 2004.
Could you please let me know if you find it interesting to author this book?
Thanks.

Hi All
I am new to drools and have started with Drools Guvnor . I am trying to
create DSL based on the sample examples in guvnor.
I have Customer as "declarative fact model" and 2 fields within it
totalItenmsPrice (integer) and discount(boolean)
I have created a DSL which contains the below code.
I need to check if the value of totalItenmsPrice is greater than 100 then
give discount to customer
[when]total cost of purchased items is greater than {num}=cust:Customer(
totalItenmsPrice > {num})
[then]Give discount to customer =cust.setDiscount(true)
and when I specify the value of num as 100 in rule editor it doenst allow.
I am not familiar with DSL syntax .
Can someone plz look into this.
