I added all necessary jar in the classpath.
Here is an excerpt from my code:
Just for information I am beginner in BRMS

/**

package fr.dto;
import java.io.*;
import javax.swing.Box.Filler;

import org.apache.commons.io.FileUtils;

import org.drools.RuleBase;
import org.drools.RuleBaseFactory;

import org.drools.WorkingMemory;
import org.drools.brms.server.util.BRDRLPersistence;

import org.drools.brms.server.util.BRXMLPersistence;
import org.drools.compiler.PackageBuilder;

import org.drools.event.DebugWorkingMemoryEventListener;
import org.drools.rule.Package;

/**

public class RulesEngine {

private RuleBase rules;

private Reader source;
private boolean debug = false;

public RulesEngine(String rulesFile) throws RulesEngineException {

super();
try {

try
{

File file = null;
String brl =null;

file = new File(rulesFile);
BRXMLPersistence read = (BRXMLPersistence) BRXMLPersistence.getInstance();

BRDRLPersistence write = (BRDRLPersistence) BRDRLPersistence.getInstance();

System.out.println("read && write instance ok \n");

brl = FileUtils.readFileToString(file,"UTF-8");
System.out.println("le fichier contient"+ brl);

String outputDRL = write.marshal(read.unmarshal(brl));// code blocked here

String drlFilePath = "src/main/rules/Test_brl_to_drl.drl";

File drlFile = new File(drlFilePath);

FileUtils.writeStringToFile(drlFile,outputDRL,"");
source = new InputStreamReader(RulesEngine.class

.getResourceAsStream(drlFilePath));

}catch (IOException ie){
System.out.println("ie.getCause(): "+ie.getCause()

+"\n"+"ie.getMessage(): "+ie.getMessage());
}

PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(source);

Package pkg = builder.getPackage();
rules = RuleBaseFactory.newRuleBase();

rules.addPackage(pkg);

} catch (Exception e) {
throw new RulesEngineException(

"Impossible de Compiler le fichier de regles : "
+ rulesFile, e);

}
}

public void executeRules(WorkingEnvironmentCallback callback) {

/*
* L’instanciation de la class workingMemory permet de determiner si

* toute si toute les conditions d’une regle sont remplies alors les
* consequences de cette regles sont executées
*/

WorkingMemory workingMemory = rules.newStatefulSession();
if (debug) {

workingMemory
.addEventListener(new DebugWorkingMemoryEventListener());

}
callback.initEnvironment(workingMemory);// initEnvironment methode de

// l'interface
/*

* L’execution des conséquences d’une regle se produit lorsqu’on invoque

* l’objet fireAllRules WorkingMemory
*/

workingMemory.fireAllRules();
}

}
