Hi i had updated spring 2.5 jar

After that getting same error

11:45:29,562 INFO  [STDOUT] 147375 [http-localhost%2F127.0.0.1-9090-3] ERROR org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/businesscaliber].[businesscaliber]  - Servlet.service() for servlet businesscaliber threw exception
javax.servlet.ServletException: Circular view path [exceptionController.do]: would dispatch back to the current handler URL [/businesscaliber/exceptionController.do] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

Privious Exception using Spring 2.0 jar

Answer 1

This StackOverflowError showing a trace with a recursive call on getSession() is recognizeable as result of a request incorrectly being dispatched through a servlet or filter which has already been called before in the request chain which causes that it is calling itself again and again.

Actually, I don't see how that's related to uploading files, maybe the Spring file upload functionality is internally forwarding the request to some special servlet or filter which by coincidence is also covered by the same url-pattern of the original request and is thus already called beforehand.

At least, you now know where to take a look to fix the particular problem. There is ambiguity and recursion in the servlet or filter mappings.
