404 Error - Client request call

Hello everyone,
I am facing issues with web service calls. There wasn't any code change to web services. But suddenly i am receiving an error # 404. This is consistent and it is occuring only for my machine, other developers are not facing this issue.

Please suggest me, how to fix this error, it been two days and still i couldn't figure out the root cause of this issue. I have observed one common pattern i.e. the client call is not hitting the service at all, hope this would help in investigating

Thanks for the help in advance.

The web service is a generated client with no WSDL and it is in a standalone java project (AA suppose). And the web project (B) is calling the web service through the java project.

Few more interesting point are,

1. when I load other java projects (C, D) to my local server which are referring to the same AA for the same client call they are not working and throwing same error as web project B is also deployed in my local server (WebSphere 6.1). And when i uninstall web project "B" from server. And try to verify the service client calls for C, D it works good.

May be there is some configuration change i need to identify for Web project B that will make my client calls work.

2. I have verified the logs and compared mine with my colleagues which is working, and found that just before we invoke the service call there is a handler WSDDJAXRPCHandlerInfoChain that is not invoked in my machine. And it over rides my machine url as end point (Mentioned in the error above as faultActor)

Hope this will help, in getting some responses.
