Error 310 (net::ERR_TOO_MANY_REDIRECTS): With Spring Security and Weblogic 9.2 MP3

In my web application, I have used basic http form based authentication of spring-security 3.1.3. When the application is deployed on Weblogic 12c (JDK 1.6), the application works fine as expected, but once I am deploying it in Weblogic 9.2 (JDK 1.5), I am getting Error 310 too many redirects.

I have applied the following fix on Weblogic domain's config.xml

Code:

---

<enforce-valid-basic-auth-credentials>false</enforce-valid-basic-auth-credentials>
</security-configuration>

---

but no luck. I am getting the same error. Once I disable spring security from web.xml, application again works fine without login facility of course. Moreover, there is no error in server log, or app log, but in access log I am getting these..

My spring-security.xml is as follows:

And here is the web.xml

http://pastebin.com/Ac32q1Lc

And here is the list of components I am using in the app

1. spring 3.2
2. spring integration 2.2.0
3. spring security 3.1.3
4. sitemesh 2.4.2
5. jaxb 2.1

&

• JDK 1.5
• Weblogic 9.2 MP3 (have to use it, coz it is in production)

Can anyone please help me out here? I am totally running out of clue. :(:(:( Moreover, when I enable the DEBUG log for spring security, here is what I get

the applog under WLS 9.2

and the applog for WLS 12c, where it was working fine as expected
