我是richfaces的新手，我正在使用JBoss EAP 5.1.1中的richfaces 3.3.3.final进行开发。
我有一个EAR应用程序，它给了我这个错误：

我必须使用请求参数（来自URL）从另一个应用程序（BPM进程）调用此应用程序。
我的托管bean有请求范围，这个参数有以下参数（faces-config.xml）：
<managed-bean>
<managed-bean-name>ordenNizaController</managed-bean-name>
<managed-bean-class>ec.gob.iepi.controladores.OrdenNizaController</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>ordenNizaBean</property-name>
<property-class>ec.gob.iepi.controladores.OrdenNizaBean</property-class>
<value>#{ordenNizaBean}</value>
</managed-property>
<managed-property>
<property-name>codigoClase</property-name>
<property-class>java.lang.String</property-class>
<value>#{param.codigoClase}</value>
</managed-property>
<managed-property>
<property-name>codigoSolicitud</property-name>
<property-class>java.lang.String</property-class>
<value>#{param.codigoSolicitud}</value>
</managed-property>
</managed-bean>
一切似乎都没问题，我使用这个服务来填充数据库中的列表（postgresql）：
@EJB(mappedName="ordenes-niza-EAR/OrdenNizaServiceImpl/local")
private OrdenNizaServiceLocal ordenNizaService;
当我启动Jboss时没有出现错误，但在运行时，它会收到错误。我的@PostConstruct方法调用了两次，我认为是由于请求范围。
这是我的托管bean，其范围是请求：

我有其他正确调用的方法，与此特定方法的不同之处在于，这个方法使用本机查询，而其他方法使用休眠。
我正在使用其他方法，应用程序运行没有问题。
答案 0 :(得分：0)
此例外与其名称一样清晰。 OrdenNizaServiceLocal没有方法findOrdenesByCodigoClase（Integer arg）
提取EAR并找到OrdenNizaServiceLocal.class然后对其进行反编译，您会发现此方法不存在。
这可能因为过时的jar版本而发生。 看看OrdenNizaServiceLocal类的jar。
