我是新来的OFBiz和我创建了简单的ofbiz的服务，并指该链接http://www.packtpub.com/article/apache-ofbiz-service-engine-part1错误而调用的ofbiz服务
我创建实践项目进入热部署。
我在servicedef/services.xml中创建的服务如下面在learningFirstService.xml
`<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>`
和创建PracticeServices.java类成src.org.ofbiz.practice.practice pakcage 和创建方法
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文件
<?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是像下面
<?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>
和controller.xml有用于示出学习形式
<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"/>
的learningForm在成功打开请求的映射。但是当我点击提交按钮时。它给控制台带来错误，如
Error in request handler:

该错误表明它找不到我定义的服务。但不明白它出错的地方。请帮帮我。
谢谢先进。

嗨，我解决了这个错误。由于语法错误，它只是在服务器启动时加载错误。但是我可以看到我的服务已注册，但在访问该服务时，会看到我的课没有发现异常。 请求处理程序错误： 异常：org.ofbiz.webapp.event.EventHandlerException 消息：服务调用错误（org.ofbiz.practice.practice.PracticeServices） ---- cause -------- -------------------------------------------------- ----------- 异常：java.lang.ClassNotFoundException 消息：org.ofbiz.practice.practice.PracticeServices – Ankit 2013-04-22 08:53:27
