Hello,
I am new to Java and Drools and have a doubt regarding the sequence of rules'
execution as stated below :-
Scenario:- I have a scenario wherein I have to apply multiple rules on multiple columns
coming in a file. To simulate that I created a 2-D array as follows
String[][] data = {
{"1791","8459625","78458745","20120610","20120610"
},
{"1792","8459623","78458745","20120610","20120610"
},
{"1793","8459624","78458745","20120610","20120610"
},
{"17944","8459626","78458745","20120610","20120610"}
};
Here each column of corresponds to a member for the following class
public class DailyPLC {
private String Id; // This value will correspond to data[i][0]
private String productCode; // This value will correspond to data[i][1]
private String customerCode; // This value will correspond to data[i][2]
private String date1; // This value will correspond to data[i][3]
private String date2; // This value will correspond to data[i][4]
private int rowNumber; // The row number to keep a track of row for which the record
exists
/*Getters and Setters defined for each of them*/
}
I have to perform checks on each of the columns, and the intent is to create all the rules
that I need for the entire array and save it in a single drl file. Also, at the execution
time, all the rules should be applied - either at once or sequentially - to all the rows
of the data.
Approach:- I tried the following
1. Created an ArrayList
ArrayList<DailyPLC> alPLCArrayList = new ArrayList<DailyPLC>();
2. Iterated over the data and stored each row into a field of the object of DailyPLC
class.
3. For every iteration, added the object into the array list.
alPLCArrayList.add(plcToday); // The plcToday is the object of the DailyPLC class
4. When executing the rules, I am adding all the items of the ArrayList one by one
and adding into the Knowledge Session.
for(DailyPLC d : alPLCArrayList)
{
ksession.insert(d);
}
Problem Faced :- The problem that I faced is that when I do FireAllRules, the rule only
validates the last record. The intent is that it should traverse the list and give a
result for all the members of the list.
Have I missed something here?
Please assist. Let me know in case you need any more information
Thanks in Advance,
Amal Gupta

Hi Wolfgang,
Thanks for your response.
Here is the rule that I had written for the file.
rule "Id != value"
when
plc : DailyPLC(Id!="1794");
then
System.out.println("Incorrect ID " + plc.getId()+ " at row : "
+ plc.getRowNumber());
end
Any pointers shall be really very helpful.

Amal

The rule you've shown will fire for all 4 elements created from the 4
rows of your table.
Something might have gone wrong while constructing the objects or the list.
To see what you have, add this rule, which should print the IDs of all
DailyPLC objects.

Hi Wolfgang,
This problem has been resolved now. I wrote the rule that you gave me, and found out that
the control was only considering the last row and the remaining rows were not considered
for execution.
I was trying to look for a solution in the Session and the ArrayList details of the
session.
I rectified it by creating a different object inside the loop when reading values, so
that the original value was not modified.
The Old code for reading the objects was
DailyPLC plcToday = new DailyPLC();
for(int iLoopIndex = 0;iLoopIndex <4; iLoopIndex++)
{
plcToday.setSrceSysId(data[iLoopIndex][0]);
plcToday.setProductCode(data[iLoopIndex][1]);
plcToday.setDistributorCode(data[iLoopIndex][2]);
plcToday.setDuePeriod(data[iLoopIndex][3]);
plcToday.setTimePeriodStartDate(data[iLoopIndex][4]);
plcToday.setRowNumber(iLoopIndex+1);
alPLCArrayList.add(plcToday);
}
Which I modified to
DailyPLC plcToday ;
for(int iLoopIndex = 0;iLoopIndex <4; iLoopIndex++)
{
/** will need to create a new object every time and
* assign it to the same reference.
* This is because in case the object is same,
* the value gets modified after
* every execution. ( Pass by value and reference )
*/
plcToday = new DailyPLC();
plcToday.setSrceSysId(data[iLoopIndex][0]);
plcToday.setProductCode(data[iLoopIndex][1]);
plcToday.setDistributorCode(data[iLoopIndex][2]);
plcToday.setDuePeriod(data[iLoopIndex][3]);
plcToday.setTimePeriodStartDate(data[iLoopIndex][4]);
plcToday.setRowNumber(iLoopIndex+1);
alPLCArrayList.add(plcToday);
}
Thank you so much for investing your time on the problem. It really helped.
Regards,
Amal
