-----------------------------------
Resolution: Duplicate
Fix Version/s: 1.4.1
> Concurrency problem in Axis using JAX-RPC
> -----------------------------------------
>
> Key: AXIS-2445
> URL: https://issues.apache.org/jira/browse/AXIS-2445
> Project: Axis
> Issue Type: Bug
> Components: Basic Architecture
> Affects Versions: 1.2.1
> Environment: Axis 1.2.1
> Spring 1.2.7
> JDK 1.4.2
> Oracle AS 10.1.2 or Tomcat 4.1
> Reporter: Peter Rohne
> Fix For: 1.4.1
>
>
> On the client side there is a threading problem because paramaters from two
> user requests are being added to the same parameter list. I'm using the
> Spring JaxRpcPortClientInterceptor which does the following:
> Call call = service.createCall(portQName, invocation.getMethod().getName());
> ...
> try {
> return call.invoke(invocation.getArguments());
> }
> ...
> Axis keeps an instance of the created Call on the Service. Have a look at
> org.apache.axis.client.Service.createCall(). It updates the instance variable
> "_call" with a new instance on every call. Furthermore, Call has the Service
> as an instance variable as well. This is passed into the Call constructor,
> and Call uses the service in the method Call.invokeEngine(...). This is
> un-thread-safe and probably the reason for the parameters on Call getting
> messed up.
> Stack trace:
> org.springframework.remoting.RemoteAccessException: Cannot access remote
