我是 OFBiz 的新手，我正在创建简单的 ofbiz 服务并引用此链接http://www.packtpub.com/article/apache-ofbiz-service-engine-part1

我将实践项目创建为热部署。

我在 servicedef/services.xml 中为 learningFirstService.xml 创建了如下服务

`<service name="learningFirstService" engine="java"
        location="org.ofbiz.practice.practice.PracticeServices" invoke="handleParameters">
        <description>Our First Service</description>
        <attribute name="firstName" type="String" mode="IN" optional="true" />
        <attribute name="lastName" type="String" mode="IN" optional="true" />
    </service>`

并在 src.org.ofbiz.practice.practice pakcage 中创建了 PracticeServices.java 类并创建了方法

    public static Map learningFirstService(DispatchContext dctx, Map context){

        System.out.println("learning first service called");
        Map resultMap = ServiceUtil.returnSuccess("You have called on service 'learningFirstService' successfully!");
        return resultMap;
    }

在我的 ofbiz-component.xml 中

    <?xml version="1.0" encoding="UTF-8"?>
<ofbiz-component name="practice"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/ofbiz-component.xsd">
      <resource-loader  name="main" type="component"/>

      <service-resource type="model" loader="main" location="servicedef/services.xml"/>

    <webapp name="practice"
       title="Practice"
       server="default-server"
       base-permission="OFBTOOLS"
       location="webapp/practice"
       mount-point="/practice"
       app-bar-display="true"/>
    <classpath type="dir" location="config"/>


</ofbiz-component>

learningforms.xml 如下

    <?xml version="1.0" encoding="UTF-8"?>
<forms xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:noNamespaceSchemaLocation="http://ofbiz.apache.org/dtds/widget-form.xsd">

    <form name="TestingServices" type="single" target="${formTarget}">
        <field name="firstName"><text/></field>
        <field name="lastName"><text/></field>
        <field name="planetId"><text/></field>
        <field name="submit"><submit/></field>
    </form>
</forms>

并且在controller.xml 中有显示学习表格的请求映射

     <request-map uri="TestFirstService">
            <event type="service" invoke="learningFirstService" />
            <response name="success" type="view" value="TestFirstService" />
        </request-map>
    <view-map name="TestFirstService" type="screen" page="component://practice/widget/PracticeScreens.xml#learningForm"/>

学习表格成功打开。但是当我点击提交按钮时。它在控制台中给出错误，例如，

        Error in request handler: 
    Exception: org.ofbiz.webapp.event.EventHandlerException
    Message: Problems getting the service model (Cannot locate service by name (learningFirstService))

    org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)
    java.lang.Thread.run(Thread.java:619)

该错误表明它无法找到我定义的服务。但无法理解它哪里出错了。请帮我。

先谢谢了。
