Problems with drools update site?
by Bagwell, Allen F
I'm wondering if anyone else has had problems updating Drools within Eclipse? I have no problems with other plugins, but with Drools I've never been able to use the update site. After making sure that Drools is uninstalled from Eclipse and attempting to add it via the remote site, I always get an Eclipse message stating:
"No features found on the selected site(s). Choose a different site or site category."
In addition, several of the developers on my team who did manage to get the update site to work cannot get it to recognize that 4.0.7 is now available. The "search for updates of the currently installed features" doesn't return 4.0.7 as ready to upload when they have 4.0.4 installed. If they try to detect 4.0.7 as a new feature, they get the same message above that I've been getting about no features found.
I've re-checked the URL and re-copied-n-pasted it several times from the web site. We are all using Europa and trying to use the "Drools 4.0.7 Eclipse Workbench for Europa 3.3" URL.
Any suggestions?

Should lhs pattern be the same for diffrent Rules in a Rule Base?
by Mehak
Hi
I have a rule using xml.
<!-- 1st Rules For Field objects-->
<rule name="Rule1">
<lhs>
<pattern identifier="outterMap" object-type="HashMap" />
<pattern identifier="innerMap" object-type="HashMap">
<from>
<expression>outterMap.get("fact")</expression>
</from>
</pattern>
<pattern identifier="field" object-type="Filterable">
<from>
<expression>innerMap.get("filterable")</expression>
</from>
</pattern>
<pattern identifier = "document" object-type="Document">
<from> <expression> field.getDocument();")</expression>
</from>
</pattern>
<eval> document.getIsNormalTask()</eval>
</lhs>
<rhs>
field.setDefaultOptionality(Boolean.TRUE);
</rhs>
</rule>
Another Rule is
<!-- 2 nd Rule for Menu Items-->
<rule name="Rule2">
<lhs>
<pattern identifier="outterMap" object-type="HashMap" />
<pattern identifier="innerMap" object-type="HashMap">
<from>
<expression>outterMap.get("fact")</expression>
</from>
</pattern>
<pattern identifier="editMode" object-type="Boolean">
<from>
<expression>innerMap.get("editMode")</expression>
</from>
</pattern>
<pattern identifier="menuItem" object-type="Filterable">
<from>
<expression>innerMap.get("filterable")</expression>
</from>
</pattern>
<pattern identifier = "document" object-type="Document">
<from> <expression> menuItem.getDocument();")</expression>
</from>
</pattern>
<eval>editMode==true && !document.isInDraftStatus()</eval>
</lhs>
<rhs>
menuItem.setDefaultVisibility((Boolean)true);
</rhs>
</rule>
The total classes that I have are:
Filterable.java
Field.java inherits Filterable (contains Document object)
MenuItem.java inherits Filterable (contains Document object)
Document.java
I am setting up the filter based on rule name such that
for MenuItems rule executed is : Rule2
For Field objects rule executed is :Rule1
The problem is that all the rules are executed for all the objects passed as
facts and statements above <lhs> are matched. As these are diffrent, runtime
error is displayed that error in Rule1, getOptionality for field producing
error.
Basically I want to know should lhs be the same for all the rules in the
Rule Base? And why are all the patterns matched for a given fact in working
memory?
Thanks

Facts - can they be non Java Beans
by sridhar123
I am trying to access Fact objects that are not always java beans. Example:
Class A {
Arraylist Class B b
getFirst() { return b.first() }
}
In above Class i dont have any variable called "first" - but returning first
element of the list.
Now following DRL throws compilation errors.
rule "Some Rule"
when
$MyFact :A()
$first : $myFact.getFirst()
then
....
....
end
Is there any way to execute the above - or i should have class variable
"first" and access that?
thank you
Sridhar

RE: [rules-users] Newbie question / NoSuchMethodError error
by Hehl, Thomas
I'm not entirely sure I understand what you're saying, but you could write a
new property that stores the int value and takes and returns a String.
Anyway, glad you figured it out.

Thomas,
I can not move the headings since I do receive "0 - 50" as a String and then
I have to return an Integer.
I've made a little program beside this to test my rule, I've launched it
using java5, it worked fine, but it does crash using java1.4.
I just found out the Integer.valueOf(int) is a new feature of java5.
So I guess I must try to run my web application using java5.
Carl.

Objet : RE: [rules-users] Newbie question / NoSuchMethodError error
No, really, java uses the valueOf methods internally to try to convert the
object specified (a String) into an Integer so it can do the comparison. You
can't do selected == "0 - 50" because "0 - 50" is a String and you cant
compare it to an Integer.
So what are you trying to do? If you want selected to be in the range
between 0 and 50 inclusive, then you need to change the heading in your
decision table. Here's an example:
daysBeforeSummons >= $1, daysBeforeSummons <= $2
and then you specify the data in your column as 0,50.
Good luck!

Thank you for answering Thomas.
Here is the code below, nothing fancy:
public void setSelected (Integer calculatedSetSelected)
{
this. calculatedSetSelected = calculatedSetSelected;
}
In fact, the problem IS that it is taking an Integer and some Drools
Internal method want to convert it using Integer.valueOf, but there is no
Integer.valueOf taking Integer.
There is something weird, in the stack trace, I get :
Caused by: java.lang.NoSuchMethodError:
java.lang.Integer.valueOf(I)Ljava/lang/Integer;
at AL_Calculation.Rule_ setSelecte_10_0.consequence(Unknown Source)
There is a missing "d" before "_10" ...

Yep. Post the code for setSelected(). I'm guessing it takes an Integer or

Greetings,
I'm new to Drools and I've written a decision table based rule using excel.
The rule validates ok and I've deployed my package fine.
I've written a piece of code to test my rules, I want to set the
calculatedRate to 125 when I get selected field equal to "0 - 50" :
...
StatelessSession statelessSession = rb.newStatelessSession(); Data data=new
Data(); data.setSelected("0 - 50"); statelessSession.execute(data); // set
private Integer field ...
When I run the code I get a exeption :
java.lang.NoSuchMethodError: java.lang.Integer.valueOf(I)Ljava/lang/Integer;
I don't understand why Drools tries to convert to Integer something which is
already Integer !!!!
-----------
Here is the rules code.
rule "setCalculateRate_11"
salience 65525
when
Data(selected == "0 - 50")
then
object.setCalculatedRate(125);
end
--------------
The CalculatedRate field is a java.lang.Integer object.
Does anybody has an idea ??
Regards,
Carl.

The CalculatedRate field is a java.lang.Integer object.
Does anybody has an idea ??

Newbie question / NoSuchMethodError error
by Cabou, Carl
Greetings,
I'm new to Drools and I've written a decision table based rule using excel.
The rule validates ok and I've deployed my package fine.
I've written a piece of code to test my rules, I want to set the calculatedRate to 125 when I get selected field equal to "0 - 50" :
...
StatelessSession statelessSession = rb.newStatelessSession(); Data data=new Data(); data.setSelected("0 - 50"); statelessSession.execute(data); // set private Integer field ...
When I run the code I get a exeption :
java.lang.NoSuchMethodError: java.lang.Integer.valueOf(I)Ljava/lang/Integer;
I don't understand why Drools tries to convert to Integer something which is already Integer !!!!
-----------
Here is the rules code.
rule "setCalculateRate_11"
salience 65525
when
Data(selected == "0 - 50")
then
object.setCalculatedRate(125);
end
