Sorry, I gave you instruction for the imports and globals...
- Open the Properties view in Eclipse
- Select the background of the flow (unselect any selected
items)
- The Properties view should refresh
- The package property should be available for edit in the view

I do not get it. What I need is to change the text of "com.sample" in
file Guess.rf. How this can be done in the Drools plugin?
Thanks,
Tak

You can change that looking at the properties of the process. Clicking
in the background of the designer.

I look at Guess.rf the xml file. I notice the Package and Import
locations are pointing to the old location. After I change them to the
new one by hand. The code works.
How can I change the above in Eclipse GUI interface?
Thanks,
Tak

java.lang.IllegalArgumentException: Unknown process ID: Number Guess
That exceptions means that you probably don't add the process definition
to the current knowledgeBuilder.
To see these kind of problems you probably need to add something like
this after KnowledgeBuilder add calls:
if ( kbuilder.hasErrors() ) {
System.err.println( builder.getErrors().toString() );
}

Mauricio,
I would like to take this example as the base to play around. That is
what I did:
1. Make a project "try" that generates the HellowWorld for me in
Eclipse.
2. add directory "log"
3. Move file Guess.java to the Java/com/sample directory. Move
Guess.drl and Guss.rf to rule directory.
4. Change Package and Implort location from org/drools/examples to
com/sample in the above three files.
Eclipse shows compiler error pointing to ShoppingExample.class.
I did the same to Shopping.java and Shopping.drl and the compiler error
is removed, and the following is the run time error messages:
Exception in thread "main"
java.lang.IllegalArgumentException: Unknown process ID: Number Guess
at org.drools.common.AbstractWorkingMemory.startProcess(
AbstractWorkingMemory.java:1615)
at org.drools.common.AbstractWorkingMemory.startProcess(
AbstractWorkingMemory.java:1604)
at org.drools.impl.StatefulKnowledgeSessionImpl.startProcess(
StatefulKnowledgeSessionImpl.java:267)
at com.sample.NumberGuessExample.main(
NumberGuessExample.java:38)
Could you please point me the right direction?
Thanks,
Tak

This is only a reference to know in which class loader is the
resource... The idea is to know that the resource (in this case:
NumberGuess.drl and NumberGuess.rf) is in the same class loader that the
ShoppingExample.class

I am a newbie with Drools rules. I just download the examples.
I notice in line19 of NumberGuessExample.java, there are two statement
that referring to ShoppingExample.class.
It seems this is different example. Could someone help me out?
Thanks,
Tak
kbuilder.add( ResourceFactory.newClassPathResource(
"NumberGuess.drl",

kbuilder.add( ResourceFactory.newClassPathResource(

ShoppingExample.
class ),
ResourceType.
