Eliane,
I guess you are using Drools 2.x. It is possible to load a set of
different rule files in the same RuleBase and then create working
memories from each of your RuleBases. Look at the following code snippet:
RuleBaseBuilder builder = new RuleBaseBuilder( );
RuleBaseContext factoryContext = new RuleBaseContext( );
for ( Iterator i = ruleFiles.iterator(); i.hasNext(); ) {
RuleFile file = (RuleFile) i.next();
InputStream fileStream = file.getInputStream();
RuleSetReader reader = new RuleSetReader( factoryContext );
RuleSet ruleSet = reader.read( fileStream );
builder.addRuleSet( ruleSet );
fileStream.close();
}
RuleBase ruleBase = builder.build();
RuleFile is a class I created myself that basically stores the DRL
file names and manages opening, uncompressing (in my case they are
compressed), etc.
It is pretty easy and straight forward.
Hope it helps.

In fact,
what i want is to have separate drl files each one containing a rule set . I
never used the xml entity but i took a look at it now and in fact to include
the external files we need to specify the parent node (something like this)
----
<!DOCTYPE rule-set [
<!ENTITY ext1 SYSTEM "./helloworld.csharp.drl.xml">
]>
---
till now this does not work in i have a absolute url exception although i think
that i specified correctly the path ...
But will the xml entities allow me to "load" different rule sets in different
files ? if yes how should the doctype be written knowing that in the drl file
the parent node is rule-set
can i write something like this ??
<!DOCTYPE [
<!ENTITY ext1 SYSTEM "./first.csharp.drl.xml">
<!ENTITY ext2 SYSTEM "./two.csharp.drl.xml">
]>
thanks for ur help,
