propagate credentials. Concurrency problems.

[arcaballero]

Hi,

I need an advice about my arquitecture. I have a binding component and a service engine, and, with a interceptor, I spread the consumer credentials using NormalizedMessage.

In addition, my service engine have many proxies (cxfse:proxy), which also need the credentials, and I set them as follow:

((BindingProvider)proxy).getRequestContext().put("credential", "true");

I think I have a problem if several consumers invoke my service simultaneously, because a consumer may use the credentials of another consumer.

¿What can I do? Do I have a problem really, or the client proxies are thread safe?

If no, I thought about creating a pool of proxies, is it a good idea?

Thanks!

Hi,

This is a good question.

The client proxy isn't thread safe in your case, take a look at to get more details when the proxy isn't thread safe.

And yeah, client proxy pool is the way to go.

Hi,

I looked the link and I think if I set the follow property:

((BindingProvider)proxy).getRequestContext().put("thread.local.request.context", "true");

I have not any problems.

I also saw the servicemix-cxf-se-2011.02.1-fuse-08-15.jar and I could find that the property "thread.local.request.context" is set in the method createProxy.

Therefore, Do I have any troubles?

Regards.

Hi,

Ah, right, cxfse:proxy is already thread safe, I made this change two years ago myself[1] but I didn't realize it when I answer you yesterday, sorry for it.

Anyway, cxfse:proxy is already thread safe and you needn't do anything else.
