Subject Re: [AXIS2] Webservice not thread save - wrong method in SOAP response
Date Mon, 12 Mar 2007 21:31:53 GMT

Do you mean you have <service scope="transportsession">?

In that case, Axis2 will share the *same* POJO object amongst all the
clients that use the same cookies. That is what session scope does. So
if your object isn't threadsafe, then you must be careful not to use
it from multiple threads on the client side that share the same
session.

Alternatively you need to make your POJOs threadsafe by synchronizing.

Paul

PS what is your client code? (Just out of interest)
