401例外在Java code

本文介绍了401例外在Java code的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的工作Drools的，我的下面code 

 导入一个org.drools.RuleBase;
进口org.drools.agent.RuleAgent;
进口org.drools.definition.type.FactType;公共类MortgageApplicationTest {
    / **
     * @参数ARGS
     *抛出：IllegalAccessException
     *抛出：InstantiationException
     * /
    公共静态无效的主要（字串[] args）抛出InstantiationException，IllegalAccessException {        规则代理剂= RuleAgent.newRuleAgent（/ mortgageapproval.properties）;
        规则库RB = agent.getRuleBase（）;        FactType的appType = rb.getFactType（mortgages.LoanApplication）;
        FactType incomeType = rb.getFactType（mortgages.IncomeSource）;        对象应用程序= appType.newInstance（）;
        对象收入= incomeType.newInstance（）;        appType.set（应用程序，量，25000）;
        appType.set（应用程序，定金，1500）;
        appType.set（应用程序，lengthYears，20）;        incomeType.set（收入，型，工作）;
        incomeType.set（收入量，65000）;
        。rb.newStatelessSession（）执行（新的对象[] {应用，收入}）;        的System.out.println（应用）;
    }}

以下是我mortgageapproval.properties文件

<$p$p><$c$c>url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST
的userName =管理员
密码=管理员

这整个code设置抛出以下401错误

 规则代理（默认）INFO（周二04月26日11时03分25秒IST 2011）：用的newInstance = true的配置，secondsToRefresh = -1

....我只在tomcat的component.xml文件是如下：

＆lt;使用者的用户名=雄猫密码=雄猫角色=经理桂/＆GT;＆LT;角色角色名称=管理/＆GT;
＆lt;使用者的用户名=admin的密码=管理员角色=管理员/＆GT;

在我的Drools'component.xml文件下面一行显示我没有给任何身份验证

 ＆LT;！ - 身份验证。当你点击应用程序，它可以绕过登录屏幕。每个人都是客人 - ＆GT;＆LT;安全：身份验证 - 法=＃{} nilAuthenticator.authenticate/＆GT;

请帮我，因为不会有太多的Drools开发商有没有...我没有得到所需的帮助....

在此先感谢


解决方案

您会得到响应一个404错误，当它试图获取您已经在 URL配置文件设置： <$c$c>http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST

执行抵押贷款包，你就指着存在特定的文件？

I am working on drools and my following code 

import org.drools.RuleBase;
import org.drools.agent.RuleAgent;
import org.drools.definition.type.FactType;

public class MortgageApplicationTest {
    /**
     * @param args
     * @throws IllegalAccessException
     * @throws InstantiationException
     */
    public static void main(String[] args) throws InstantiationException, IllegalAccessException {

        RuleAgent agent = RuleAgent.newRuleAgent("/mortgageapproval.properties");
        RuleBase rb = agent.getRuleBase();

        FactType appType = rb.getFactType("mortgages.LoanApplication");
        FactType incomeType = rb.getFactType("mortgages.IncomeSource");

        Object application = appType.newInstance();
        Object income = incomeType.newInstance();

        appType.set(application, "amount", 25000);
        appType.set(application, "deposit", 1500);
        appType.set(application, "lengthYears", 20);

        incomeType.set(income, "type", "Job");
        incomeType.set(income, "amount", 65000);


        rb.newStatelessSession().execute(new Object[] {application, income});

        System.out.println(application);
    }

}

Following is my mortgageapproval.properties file 

url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST
userName=admin
password=admin

This whole code setup Is throwing following 401 error

RuleAgent(default) INFO (Tue Apr 26 11:03:25 IST 2011): Configuring with newInstance=true, secondsToRefresh=-1

.... I have given authentication only at tomcat's component.xml file which is as follows

<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>

<role rolename="admin"/>
<user username="admin" password="admin" roles="admin"/>

In my drools' component.xml following line shows I have not given any authentication

<!-- NO authentication. This will bypass the login screen when you hit the app. Everyone is "guest" -->

<security:identity authenticate-method="#{nilAuthenticator.authenticate}"/>

Please help me out since there are not many drools developer are there... I am not getting required help....

thanks in advance

解决方案

You're getting a 404 error in response when it's trying to fetch the file that you've configured in the url setting: http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST

Do the mortgages package and the specific file you're pointing to exist?
