I want to learn drools and maven can any one help me with the links for configuring drools and maven and writing a basic hello world example using them.
Thanks in advance
You should first read the manual, then try google it. There have also been questions like this asked before, for example: How to deploy Drools Flow and rules by my web application
But anyways. This is how to integrate it if you use Maven and Spring:
you first need to include Drools dependencies:
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-core</artifactId>
<version>${drools.version}</version>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-compiler</artifactId>
<version>${drools.version}</version>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-spring</artifactId>
<version>${drools.version}</version>
</dependency>
Define the application context:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:drools="http://drools.org/schema/drools-spring"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring.xsd">
<drools:kbase id="kbase1">
<drools:resources>
<drools:resource source="classpath:Sample.drl" />
</drools:resources>
</drools:kbase>
<drools:ksession id="ksession1" type="stateful" kbase="kbase1" />
</beans>
Then you can inject ksession1
as a bean.
