yes someone found that one already, it is fixed in trunk. I'm hoping to
release a code complete MR4 in a few hours, just waiting on some IDE
code to be committed.<br>

<pre wrap="">Hi,
I solved my first multi thread problem by having a shared RuleBase for
all threads. My problem is now with Objects insertion. Here is the trace
that occur :
java.lang.ArrayIndexOutOfBoundsException: 17

at java.lang.Thread.run(Thread.java:534)
The program that I made to reproduce this error create threads that each
create a working memory from a static rule base (that works great) and
then insert some objects in this working memory. I have this error in a
real j2ee program.
Here is a listing of the code :
package test;
import java.io.IOException;
import java.io.InputStreamReader;
import org.drools.RuleBase;
import org.drools.RuleBaseFactory;
import org.drools.StatefulSession;
import org.drools.compiler.DroolsParserException;
import org.drools.compiler.PackageBuilder;
import org.drools.compiler.PackageBuilderConfiguration;
public class TestThreads {
public static RuleBase rulebase;
public static void main(String[] args) {
PackageBuilderConfiguration pkgBuilderCfg =
new PackageBuilderConfiguration();
PackageBuilder builder = new PackageBuilder(pkgBuilderCfg);
try {
builder.addPackageFromDrl(new InputStreamReader(
TestThreads.class.getResourceAsStream( "Sample.drl" )));
} catch (DroolsParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
rulebase = RuleBaseFactory.newRuleBase();
try {
rulebase.addPackage(builder.getPackage());
} catch (Exception e) {
e.printStackTrace();
}
for(int i = 0; i<100 ; i++) {
DroolsThread tt = new DroolsThread("Thread " + i);
new Thread(tt).start();
}
}
public static class Fact {
public String s;
public Fact(String s){
this.s = s;
}
public String getS() {
return s;
}
}
public static class DroolsThread implements Runnable {
private String id;
public DroolsThread(String id) {
this.id = id;
}
public void run() {
StatefulSession session = rulebase.newStatefulSession();
for(int i = 0; i < 100; i++) {
session.insert(new Fact(id));
}
}
}
}
I am using Drools MR3.
Thanks for your help.
