MULE連接德比錯誤

Question

我創建DB德比和後續的錯誤返回瀏覽連接：

ERROR 2016-03-01 23:20:31,168 
[[fiapacessobancodedados].HTTP_Listener_Configuration.worker.01]

Type     : org.mule.api.MessagingException

</spring:beans>

    <db:insert config-ref="Derby_Configuration" doc:name="Database"> 
     <db:parameterized-query><![CDATA[INSERT INTO FIAP.ALUNO (CODIGO, NOME_ALUNO)

    </db:insert>

我有如下修改你的流量和連接的URL，現在將正常工作： -

<spring:beans> 
     <spring:bean id="Derby_Data_Source" class="org.enhydra.jdbc.standard.StandardXADataSource" > 
      <spring:property name="driverName" value="org.apache.derby.jdbc.EmbeddedDriver"/> 
      <!-- <spring:property name="url" value="jdbc:derby:SOAFiap;create=true"/> --> 
      <spring:property name="url" value="jdbc:derby:memory:SOAFiap;create=true"/> <!-- Create Database in memory --> 
     </spring:bean> 
</spring:beans> 
<db:generic-config name="Generic_Database_Configuration" dataSource-ref="Derby_Data_Source" doc:name="Generic Database Configuration"/> 
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/> 

    <flow name="DerbyDBFlow1" > 
      <http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/> 

     <db:insert config-ref="Generic_Database_Configuration" doc:name="Database"> 
      <db:parameterized-query><![CDATA[INSERT INTO FIAP.ALUNO (CODIGO, NOME_ALUNO) 
VALUES (5, 'Igor Koba')]]></db:parameterized-query> 
      </db:insert> 

     <logger message="#[message.payload]" level="INFO" doc:name="Logger"/> 
    </flow> 

這是工作對我罰款。
您可以修改URL按您的DBNAME，用戶名等
