Class JaxRpcPortClientInterceptor

    java.lang.Object
      org.springframework.remoting.jaxrpc.LocalJaxRpcServiceFactory
          org.springframework.remoting.jaxrpc.JaxRpcPortClientInterceptor

All Implemented Interfaces:
  Advice, Interceptor, MethodInterceptor, InitializingBean

Direct Known Subclasses:
  JaxRpcPortProxyFactoryBean

    public class JaxRpcPortClientInterceptor

extends LocalJaxRpcServiceFactory
implements MethodInterceptor, InitializingBean

`MethodInterceptor` for accessing a specific port of a JAX-RPC service. Uses either `LocalJaxRpcServiceFactory`'s facilities underneath or takes an explicit reference to an existing JAX-RPC Service instance (e.g. obtained via `JndiObjectFactoryBean`).

Allows to set JAX-RPC's standard stub properties directly, via the "username", "password", "endpointAddress" and "maintainSession" properties. For typical usage, it is not necessary to specify those.

In standard JAX-RPC style, this invoker is used with an RMI service interface. Alternatively, this invoker can also proxy a JAX-RPC service with a matching non-RMI business interface, that is, an interface that declares the service methods without RemoteExceptions. In the latter case, RemoteExceptions thrown by JAX-RPC will automatically get converted to Spring's unchecked RemoteAccessException.

Setting "serviceInterface" is usually sufficient: The invoker will automatically use JAX-RPC "dynamic invocations" via the Call API in this case, no matter whether the specified interface is an RMI or non-RMI interface. Alternatively, a corresponding JAX-RPC port interface can be specified as "portInterface", which will turn this invoker into "static invocation" mode (operating on a standard JAX-RPC port stub).

### setCustomProperties

    public void setCustomProperties(Properties customProperties)

  Set custom properties to be set on the stub or call.

  Can be populated with a String "value" (parsed via PropertiesEditor) or a "props" element in XML bean definitions.

  See Also:
    `Stub._setProperty(java.lang.String, java.lang.Object)`, `Call.setProperty(java.lang.String, java.lang.Object)`

### setCustomPropertyMap

    public void setCustomPropertyMap(Map customProperties)

  Set custom properties to be set on the stub or call.

  Can be populated with a "map" or "props" element in XML bean definitions.

  See Also:
    `Stub._setProperty(java.lang.String, java.lang.Object)`, `Call.setProperty(java.lang.String, java.lang.Object)`

### getCustomPropertyMap

    public Map getCustomPropertyMap()

  Allow Map access to the custom properties to be set on the stub or call, with the option to add or override specific entries.

  Useful for specifying entries directly, for example via "customPropertyMap[myKey]". This is particularly useful for adding or overriding entries in child bean definitions.

### addCustomProperty

    public void addCustomProperty(String name,
                                  Object value)

  Add a custom property to this JAX-RPC Stub/Call.

  Parameters:
    `name` - the name of the attribute to expose
    `value` - the attribute value to expose
  See Also:
    `Stub._setProperty(java.lang.String, java.lang.Object)`, `Call.setProperty(java.lang.String, java.lang.Object)`

### setServiceInterface

    public void setServiceInterface(Class serviceInterface)

  Set the interface of the service that this factory should create a proxy for. This will typically be a non-RMI business interface, although you can also use an RMI port interface as recommended by JAX-RPC here.

  Calls on the specified service interface will either be translated to the underlying RMI port interface (in case of a "portInterface" being specified) or to dynamic calls (using the JAX-RPC Dynamic Invocation Interface).

  The dynamic call mechanism has the advantage that you don't need to maintain an RMI port interface in addition to an existing non-RMI business interface. In terms of configuration, specifying the business interface as "serviceInterface" will be enough; this interceptor will automatically use dynamic calls in such a scenario.

  See Also:
    `Service.createCall(javax.xml.namespace.QName)`, `setPortInterface(java.lang.Class)`

### getServiceInterface

    public Class getServiceInterface()

  Return the interface of the service that this factory should create a proxy for.

### setPortInterface

    public void setPortInterface(Class portInterface)

  Set the JAX-RPC port interface to use. Only needs to be set if a JAX-RPC port stub should be used instead of the dynamic call mechanism. See the javadoc of the "serviceInterface" property for more details.

  The interface must be suitable for a JAX-RPC port, that is, it must be an RMI service interface (that extends `java.rmi.Remote`).

  NOTE: Check whether your JAX-RPC provider returns thread-safe port stubs. If not, use the dynamic call mechanism instead, which will always be thread-safe. In particular, do not use JAX-RPC port stubs with Apache Axis, whose port stubs are known to be non-thread-safe.

  See Also:
    `Service.getPort(javax.xml.namespace.QName, java.lang.Class)`, `Remote`, `setServiceInterface(java.lang.Class)`

### getPortInterface

    public Class getPortInterface()

  Return the JAX-RPC port interface to use.

### setLookupServiceOnStartup

    public void setLookupServiceOnStartup(boolean lookupServiceOnStartup)

  Set whether to look up the JAX-RPC service on startup.

  Default is "true". Turn this flag off to allow for late start of the target server. In this case, the JAX-RPC service will be lazily fetched on first access.

### setRefreshServiceAfterConnectFailure

    public void setRefreshServiceAfterConnectFailure(boolean refreshServiceAfterConnectFailure)

  Set whether to refresh the JAX-RPC service on connect failure, that is, whenever a JAX-RPC invocation throws a RemoteException.

  Default is "false", keeping a reference to the JAX-RPC service in any case, retrying the next invocation on the same service even in case of failure. Turn this flag on to reinitialize the entire service in case of connect failures.

### afterPropertiesSet

    public void afterPropertiesSet()

  Prepares the JAX-RPC service and port if the "lookupServiceOnStartup" is turned on (which it is by default).

  Specified by:
    `afterPropertiesSet` in interface `InitializingBean`

### prepare

    public void prepare()
                 throws RemoteLookupFailureException

  Create and initialize the JAX-RPC service for the specified port.

  Prepares a JAX-RPC stub if possible (if an RMI interface is available); falls back to JAX-RPC dynamic calls else. Using dynamic calls can be enforced through overriding `alwaysUseJaxRpcCall()` to return `true`.

  `LocalJaxRpcServiceFactory.postProcessJaxRpcService(javax.xml.rpc.Service)` and `postProcessPortStub(javax.xml.rpc.Stub)` hooks are available for customization in subclasses. When using dynamic calls, each can be post-processed via `postProcessJaxRpcCall(javax.xml.rpc.Call, org.aopalliance.intercept.MethodInvocation)`.

  Throws:
    `RemoteLookupFailureException` - if service initialization or port stub creation failed

### alwaysUseJaxRpcCall

    protected boolean alwaysUseJaxRpcCall()

  Return whether to always use JAX-RPC dynamic calls. Called by `afterPropertiesSet`.

  Default is "false"; if an RMI interface is specified as "portInterface" or "serviceInterface", it will be used to create a JAX-RPC port stub.

  Can be overridden to enforce the use of the JAX-RPC Call API, for example if there is a need to customize at the Call level. This just necessary if you you want to use an RMI interface as "serviceInterface", though; in case of only a non-RMI interface being available, this interceptor will fall back to the Call API anyway.

  See Also:
    `postProcessJaxRpcCall(javax.xml.rpc.Call, org.aopalliance.intercept.MethodInvocation)`

### reset

    protected void reset()

  Reset the prepared service of this interceptor, allowing for reinitialization on next access.

  Determine whether the given RMI exception indicates a connect failure.

  The default implementation returns `true` unless the exception class name (or exception superclass name) contains the term "Fault" (e.g. "AxisFault"), assuming that the JAX-RPC provider only throws RemoteException in case of WSDL faults and connect failures.

  Parameters:
    `ex` - the RMI exception to check
