SCA 问题

Question

我的sca——composit文件如下
<?xml version="1.0" encoding="UTF-8"?><composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
  xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0"
targetNamespace="http://LoanBroker"
  name="LoanBroker">
  <component name="LoanBrokerServiceComponent">
 <implementation.java class="loanbroker.LoanBrokerImpl"/>
<service name="LoanBrokerService">
<interface.java interface="loanbroker.LoanBrokerService"/>
<tuscany:binding.rmi host="localhost" port="8099" serviceName="LoanBrokerRMIService"/>
</service>   
  <reference name="bank0Service" target="Bank0ServiceComponent" />
  <reference name="bank1Service" target="Bank1ServiceComponent" />
  <reference name="bank2Service" target="Bank2ServiceComponent" />
  <reference name="bank3Service" target="Bank3ServiceComponent" />
  <reference name="houseLoanAgencyService" target="HouseLoanAgencyServiceComponent" />
  </component>
  <component name="Bank0ServiceComponent">
  <implementation.java class="loanbroker.Bank0Impl"/>
  </component>
    
  <component name="Bank1ServiceComponent">
  <implementation.java class="loanbroker.Bank1Impl"/>
  </component>   
    
  <component name="Bank2ServiceComponent">
  <implementation.java class="loanbroker.Bank2Impl"/>
  </component>
    
  <component name="Bank3ServiceComponent">
  <implementation.java class="loanbroker.Bank3Impl"/>
  </component>     <component name="HouseLoanAgencyServiceComponent">
  <implementation.java class="loanbroker.HouseLoanAgencyImpl"/>
  </component>
</composite>
server代码如下
 public static void main(String[] args) throws Exception {
  System.out.println("Starting of the SCA LoanBroker Application exposed as RMI Services...");
    
  SCADomain scaDomain = SCADomain.newInstance("loanbroker/LoanBrokerRMIServer.composite");
    
try {
  System.out.println("SOA服务器启动完毕（按回车键停止服务）");
  System.in.read();
  } catch (IOException e) {
  e.printStackTrace();
  }  scaDomain.close();
  // System.exit(0);
  }
会出现如下错误
