Hello All,
|
I am using KIE Workbench 6.1.0.Final and my Eclipse project where I am trying to execute rules is also 6.1.0 Runtime enabled. I like to know how I can execute/load rules created using Drools Guvnor, from my java application. Before posting this question, I have looked at the following similar questions and tried the given approaches but none of them worked for me.
|
public void load1(){
KieServices kieServices = KieServices.Factory.get();
ReleaseId releaseId = kieServices.newReleaseId( "com.example.rule", "RuleProject", "1.0" );
KieContainer kContainer = kieServices.newKieContainer( releaseId );
KieBaseConfiguration kieBaseConf = kieServices.newKieBaseConfiguration();
kieBaseConf.setOption( EventProcessingOption.STREAM );
KieBase kBase = kContainer.newKieBase(kieBaseConf);
for ( KiePackage a : kBase.getKiePackages()) {
for (Rule r : a.getRules()) {
System.out.println("KiePackage {} Rule {}"+ new Object[]{a.getName()+"-"+ r.getName()});
}
}
}
Enter code here...Exception
java.lang.RuntimeException: Cannot find KieModule: com.example.rule:RuleProject:1.0 at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieContainer(KieServicesImpl.java:99)
Approach 2.
public void load2(){
String url = "http://example.com/drools/maven2/com/example/rule/RuleProject/1.0/RuleProject-1.0.jar";
ReleaseIdImpl releaseId = new ReleaseIdImpl("com.example.rule", "RuleProject", "1.0");
KieServices kieServices = KieServices.Factory.get();
kieServices.getResources().newUrlResource(url);
KieContainer kieContainer = kieServices.newKieContainer(releaseId);
// check every 5 seconds if there is a new version at the URL
KieScanner kieScanner = kieServices.newKieScanner(kieContainer);
kieScanner.start(5000L);
// alternatively:
// kieScanner.scanNow();
Scanner scanner = new Scanner(System.in);
while (true) {
//runRule(kieContainer);
System.out.println("Press enter in order to run the test again....");
scanner.nextLine();
}
}
Enter code here...Exception
java.lang.RuntimeException: Cannot find KieModule: com.example.rule:RuleProject:1.0 at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieContainer(KieServicesImpl.java:99)
Approach 3.
public void load3() throws IOException{
String url = "http://example.com/drools/maven2/com/example/rule/RuleProject/1.0/RuleProject-1.0.jar";
KieServices ks = KieServices.Factory.get();
KieRepository kr = ks.getRepository();
UrlResource urlResource = (UrlResource) ks.getResources()
.newUrlResource(url);
urlResource.setUsername("admin");
urlResource.setPassword("password");
urlResource.setBasicAuthentication("enabled");
InputStream is = urlResource.getInputStream();
KieModule kModule = kr.addKieModule(ks.getResources()
.newInputStreamResource(is));
KieContainer kContainer = ks.newKieContainer(kModule.getReleaseId());
kContainer.newStatelessKieSession();
}

For option #3 you will need to configure a User ID and password in your Maven settings.xml file. The User and password should be for a workbench user with the admin role as the workbench Maven repository requires authentication. I suspect when downloading the JAR from the browser you have already been authenticated for the session.

Thanks Michael for a quick reply. I will try your suggestion and let you know.
Can you also help me fixing approach1 which is more close to my usecase ?
thanks again.

To be honest, from what I know about KieScanner, I'd have expected options 1, 2 and 3 to work as you have the workbench repository configured in your consuming application's pom. 1 and 2 might need the credentials configured in settings.xml - perhaps the error reporting us misleading.
@mfusco.. any ideas?

Look up settings.xml for maven both in drools and maven docs. There you will see how to add remote repositories and set login/pass.

Change your eclipse runtime to 6.0 0 and keep the workbench to 6.1.0 final. This should work with your approach 3. However you won’t be able to use KieScanner.

Hi,
I am facing problem for same thing(using approach 3) except I am using 6.3.0 Final & simple java web project.
I opened post: Drool 6.2 - Failed to run rule using loading kie project artifact jar in "non-maven java web project
I tried with 6.3.0Final But get error java.lang.RuntimeException: Cannot find KieModule: com.eno:Test1:LATEST.
Please see my post for more detail. Please help me to solve it.

KieScanner can't be used in approaches 2,3 because the scanner check only repositories listed in settings.xml file (placed at default location user_home/.m2/settings.xml or customized by use kie.maven.settings.custom System property). In other side, once you provided correct settings.xml file with
repository url, there is not needed to specify the jar's url since Drools does it itself and better (it takes in account Ranged versions, LATEST flag and other) then the described above trivial direct resolution of GAV (groupId:ArtifactId:version) to an Url.
Resume:
Approach 1 is preferable once settings.xml supported correctly, since the scanner will also work.
Approaches 2,3 will work for only one-time artifact loading and it is not correct to use scanner here.
Tested with Drools 6.4.0.Final, with Artifactory remote repository and rather with just folder on disk which contains my artifacts (has correct Maven structure)

1. create settings xml like this:
<?xml version='1.0' encoding='UTF-8'?>
<settings xsi:schemaLocation='http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd' xmlns='http://maven.apache.org/SETTINGS/1.0.0' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
<profiles>
<profile>
<id>DefaultProfile</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<repositories>
<repository>
<id>kieProjects</id>
<name>Kie Projects</name>
<url>http://your_host:your_port/artifactory/libs-release-local</url>
<layout>default</layout>
</repository>
</repositories>
</profile>
</profiles>
</settings>
You may add server with the same id as repository to provide authentication credentials, you also may use some local folder as url ("file:/C:/some_local_repositoryfolder"). In your case it will probably "http://example.com/drools/maven2"
2. pass settings.xml file's path as following system property kie.maven.settings.custom to you application.
3. The Code:
import org.kie.api.KieBase
import org.kie.api.KieServices
import org.kie.api.builder.KieRepository
import org.kie.api.builder.KieScanner
import org.kie.api.runtime.KieContainer
import org.kie.api.runtime.KieSession. . .KieServices ks = KieServices.Factory.get();
// Creates virtual local repository
KieRepository kieRepository = ks.getRepository();
ReleaseId releaseId = kieServices.newReleaseId( "com.example.rule", "RuleProject", "1.0" );
KieBase kieBase = null;
try {
KieContainer kieContainer = ks.newKieContainer(releaseId);
// check every 5 seconds if there is a new version at the URL
KieScanner kieScanner = ks.newKieScanner(kieContainer);
//kieScanner.scanNow();
kieBase = kieContainer.getKieBase();
kieScanner.start(5000L);
} catch (Exception e) {
// Failed to find required KieArtifact
} . . .
KieSession kieSession
try{
kieSession = kieBase.newKieSession();
kieSession.insert("some fact");
kieSession.fireAllRules();
}
finally {
if(kieSession) {
kieSession.dispose();
}
}Good Luck!

Thanks for reply but I already implemented using setting.xml & for runtime update using version as com.eno:xyz:1-SNAPSHOT.
