HttpRemote exception:I can not get the data from server!
when i run client application via webstart，i found the data can not got from server.The configuration files and some codes as follows:
clientContext.xml:
remoting-servlet.xml:Code:<bean id="depotSubFrameManager" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean"><property name="serviceUrl"><value>http://${serverName}:${httpPort${contextPath}/remoting/DepotSubFrameManager</value></property> <property name="serviceInterface"> <value>com.jctx.trms.hibernate.bussiness.DepotSubFrameManager</value></property> </bean>applicationContext.xml:Code:<bean name="/DepotSubFrameManager" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter"> <property name="service"> <ref bean="depotSubFrameManager"/> </property> <property name="serviceInterface"> <value>com.jctx.trms.hibernate.bussiness.DepotSubFrameManager</value></property> </bean>
get the bean:Code:<bean id="depotSubFrameDAO" class="com.jctx.trms.hibernate.DAO.DepotSubFrameDAOImpl"> <property name="sessionFactory"> <ref local="sessionFactory"/> </property> </bean> <bean id="depotSubFrameManager" parent="txProxyTemplate"> <property name="target"> <bean class="com.jctx.trms.hibernate.bussiness.DepotSubFrameManagerImpl"> <property name="depotSubFrameDAO"><ref bean="depotSubFrameDAO"/></property> </bean> </property> </bean>call the service:Code:public static DepotSubFrameManager getDepotSubFrameManager() { return (DepotSubFrameManager) (getContext().getBean("depotSubFrameManager")); }my dao is:Code:DepotSubFrameManager depotsubframem = (DepotSubFrameManager) GlobalApplicationContext.getDepotSubFrameManager(); System.out.println("the value of depotsubframem is " + depotsubframem); List lts = depotsubframem.findAll(); [color=red]//(1)[/color] Iterator its = lts.iterator();in server,the console print the size of list is 6,but in client,the program run to the row which marked (1) throw the java.lang.NullPointerException,and in the console of client ,the value of depotsubframem isCode:public List findAll(){ List list = getHibernateTemplate().find("from com.jctx.trms.hibernate.persistence.DepotSubFrame"); System.out.println("the length of size is " + list.size()); [color=red] //(2)[/color] return list; }
the exception of client console is:Code:HTTP invoker proxy for service URL [http://localhost:8080/trms/remoting/DepotSubFrameManager]
Can anyone please spot what I have done wrong, thanks very much.Code:java.lang.NullPointerException at com.jctx.trms.hibernate.persistence.BaseObject.hashCodeReflectionAppend(BaseObject.java:115) at
