and service :

@service("test") public class projserviceimpl extends remoteserviceservlet implements projservice {     private static final log log = logfactory.getlog(projserviceimpl.class);        @autowired     poicategdao poicategdao;      public string greetserver(string input) throws illegalargumentexception {         // verify input valid.          if (!fieldverifier.isvalidname(input)) {             // if input not valid, throw illegalargumentexception             // client.             throw new illegalargumentexception(                     "name must @ least 4 characters long");         }         //requestcontextutils.getwebapplicationcontext(request); //      string serverinfo = getservletcontext().getserverinfo(); //      string useragent = getthreadlocalrequest().getheader("user-agent");            return "hello, " + input + "!<br><br>i running .<br><br>it looks using:<br>";         }      @override     //@transactional(propagation = propagation.required, rollbackfor = exception.class)     public void testdao(integer id) throws illegalargumentexception {         // todo auto-generated method stub         poicateg x=poicategdao.findbyid(id);         poicateg z=poicategdao.findbyid(id);     }  } 

and applicaationcontext2.xml

<beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:p="http://www.springframework.org/schema/p"     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"      xmlns:tx="http://www.springframework.org/schema/tx"     xsi:schemalocation="                 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd                 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd                 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">      <context:annotation-config />  <tx:annotation-driven transaction-manager="transactionmanager" />  <context:component-scan base-package="ne.projl.*" /> <!--    <context:component-scan base-package="fully qualified" /> -->  <bean class="org.springframework.orm.jpa.localentitymanagerfactorybean" id="entitymanagerfactory">         <property name="persistenceunitname" value="mypunit" />     </bean>      <bean class="org.springframework.orm.jpa.jpatransactionmanager" id="transactionmanager">         <property name="entitymanagerfactory" ref="entitymanagerfactory" />     </bean>   </beans> 

please note if put context:component-scan in applicationcontext.xml ( not applicatincontext2.xml service bean detected. ). if there's other info should provide tell.

if remember correctly, base package in component scan requires package name. underlying sub-package included.

therefore correct setting should

<context:component-scan base-package="ne.projl" />
