Error while calling OfBiz service

I am new to OFBiz and I am creating the simple ofbiz service and referring this link http://www.packtpub.com/article/apache-ofbiz-service-engine-part1

I created practice project into hot-deployment.

I created services in servicedef/services.xml as below for 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>`

and created PracticeServices.java class into src.org.ofbiz.practice.practice pakcage and created method

    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;
    }

and in my ofbiz-component.xml

    <?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 is like below

    <?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>

and in controller.xml there is request mapping for showing learning form

     <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"/>

The learningForm in successfully opening. but when i click on submit button. it gives error in console like,

        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)

That error shows it can't locate the service that i defined. But can't understand where its going wrong. Please help me.

Thanks in advanced.
