Re: [rules-users] Drools With Spring Framework Problem
Niyas, This one seems to be a conflict when using JDT and tomcat. Look at the JBoss Rules wiki that I believe someone posted a solution for that there.

Re: [rules-users] Drools With Spring Framework Problem
Hi,
WIKI Knowledgebase have a solution for the error
like:org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem;
I have added the JANINO compiler in the PackageBuilderConfiguration in
the Java Code: But It's not resolving my problem and the same error
message is coming:
My Code:
public class RuleBaseBeanFactory implements FactoryBean, InitializingBean {
private List drlResourceList;
private RuleBase ruleBase;
private PackageBuilderConfiguration packageBuilderConfiguration;
public void setDrlResourceList(List drlResourceList) {
this.drlResourceList = drlResourceList;
}
public void afterPropertiesSet() throws Exception {
Assert.notEmpty(drlResourceList, "drlResourceList must not be empty");
PackageBuilder builder = (packageBuilderConfiguration != null
? new PackageBuilder(packageBuilderConfiguration) : new
PackageBuilder());
packageBuilderConfiguration.setCompiler(packageBuilderConfiguration.JANINO);
for (Resource resource : drlResourceList) {
builder.addPackageFromDrl(new
InputStreamReader(resource.getInputStream())); // TODO will use
default encoding which might not be wanted
}
ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(builder.getPackage());
}
public RuleBase getObject() {
return ruleBase;
}
public Class getObjectType() {
return RuleBase.class;
}
public boolean isSingleton() {
return true;
}
public void
setPackageBuilderConfiguration(PackageBuilderConfiguration
packageBuilderConfiguration) {
this.packageBuilderConfiguration = packageBuilderConfiguration;
}
}
Please suggest a solution..

Re: [rules-users] Drools With Spring Framework Problem
Hi Niyas, This is something I faced yesterday but did not had the time to work on it yet. Basically, 2 problems: 1. Error message is crap... we need to improve that. 2. It should not be raising any error. The error means you have a String attribute you are trying to compare using operators like >, <, >=, <=. Example: Person( name > 'Edson' ) And I think the above should work but is not working. I will open a JIRA for that. Meanwhile, if you need to have such constraint, a workaround is to use a predicate: Person( $n : name, ( $n.compareTo( 'Edson' ) > 0 ) ) []s Edson Niyas wrote: I have tried of using the sample coding given the link given by you: But i am getting the following error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ruleBase' defined in ServletContext resource [/WEB-INF/insurance-servlet.xml]: Initialization of bean failed; nested exception is java.lang.RuntimeException: Operator '40' does not exist for StringEvaluator org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:403) org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:233) org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:145) org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:277) org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:313) org.springframework.web.context.support.AbstractRefreshableWebApplicationContext.refresh(AbstractRefreshableWebApplicationContext.java:139) org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:306) org.springframework.web.servlet.FrameworkServlet.initWebApplicationContext(FrameworkServlet.java:251) org.springframework.web.servlet.FrameworkServlet.initServletBean(FrameworkServlet.java:220) org.springframework.web.servlet.HttpServletBean.init(HttpServletBean.java:112) javax.servlet.GenericServlet.init(GenericServlet.java:211) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) java.lang.Thread.run(Thread.java:595) My insurance-servlet.xml: class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> class="org.springframework.web.servlet.view.InternalResourceViewResolver"> /WEB-INF/jsp/ .jsp type="org.springframework.core.io.Resource">classpath:/com/sample/Approval.drl class="org.drools.compiler.PackageBuilderConfiguration"> On 2/19/07, Olenin, Vladimir (MOH) <[EMAIL PROTECTED]> wrote: Check out 'Spring Modules' subproject - it has a DROOLS integration module.

Re: [rules-users] Drools With Spring Framework Problem
Hi Niyas - I'm also trying to implement similar approach wiht Spring and Drools, so I've done similar search and found some stuff. CHeck out this link: http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesWithSpringFramework Using the sample code there I was able to come up with a component that encapsulates both the PackageBuilder and RuleBase - this component is called EventRulBase. Spring builds this component based on the configuration I specify in the aplicaitonContext-myapp.xml file...So the sequence goes something like this: 1) Spring initializes the Beans defined in applicationContext-myapp.xml file at startup. The bean implements an init() method which I instruct Spring to invoke AFTER it finishes setting up all properties on the bean in the init() method I setup the components that read the DRL file, compile and initialize the RuleBase object. 2) My EventRuleBase component is a Singleton that can return RuleBase objects from which calling clients can instantiate new Working Memory objects, assert objects and facts into it, fire rules, etc... I'm still in the process of building it but that's the general flow. Hope it helps - if you need more let me know.
