-----------------------------------------------
Hi,
I am facing this issue on my Axis client as well. The Target Endpoint is
getting overwritten in multithreaded environment. I looked into Axis 1.4 code
and found out that in Service class if Transport type is same, service object
will use same Transport object. So if URL is changed by another thread, it
affects the previous Axis calls which had different URL. I think
setTargetEndpoint method in Axis call method is causing this issue.
Let me know if my issue is similar to this one.
Thanks.

> Key: AXIS-2540
> URL: https://issues.apache.org/jira/browse/AXIS-2540
> Project: Axis
> Issue Type: Bug
> Components: Basic Architecture
> Affects Versions: 1.4
> Environment: all platforms
> Reporter: Muruga Chinnananchi
> Priority: Critical
> Labels: thread-safety
> Attachments: ASF.LICENSE.NOT.GRANTED--HTTPSender.java
>
>
> the targetURL in HTTPSender is shared by multiple threads, in a highly
> concurrent and multi-threaded environment, and multiple threads modifies the
> targetURL and the messages endup going to wrong endpoint.
> Our customers experienced this problem in production environment and we
> created a simple test case to reproduce this, just place Thread.sleep(1000)
> right before calling writeToSocket ( ) and try to send messages from multiple
> threads to different endpoints. you would notice the messages going to wrong
> endpoints.
> Fix: Remove the targetURL instance variable in HTTPSender.java and make it
> local to the public void invoke(MessageContext msgContext) throws AxisFault
> method. I am attaching the fixed HTTPSender.java. I fixed it on top of 1.4
> release source. I thought it would benefit others who uses wsif-axis in
> multi-threaded environment.
