Applet Application throwing ClassFormatError

Thu Oct 25 06:01:34 EDT 2012

Hi, 

I tried with Apache 2.2, but still I am getting the same error. 

I tried to debug the HTTP Traffic using Fiddler and saw that a 302 redirect
response is sent when a request goes for applet jar. 

Machine : vmah-cfd09 is the SP + Apache + Application.
            : dhrn0zr1 is the IDP

Following is the HTTP Traffic : 

*1.* Request for applet.jar : 

   GET https://vmah-cfd09/test/applet.jar HTTP/1.1
	accept-encoding: pack200-gzip,gzip
	User-Agent: Mozilla/4.0 (Windows 7 6.1) Java/1.6.0_33
	Host: vmah-cfd09
	Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
	Connection: keep-alive

*2. *Response for above applet.jar

	HTTP/1.1 302 Found

*3. *Above 302 goes to GET https://dhrn0zr1/idp/profile/SAML2/Redirect/SSO?. 
   So a request is sent to above URL.

*4. *The response for above request is 302 for : 
    https://dhrn0zr1:443/idp/AuthnEngine

*5.* Above 302 goes to "https://dhrn0zr1/idp/AuthnEngine "
   So a request is sent to above URL. 

*6.* The response of above URL is again a 302 for : 
	: https://dhrn0zr1:443/idp/profile/SAML2/Redirect/SSO

*7. * Above 302 goes to GET
https://dhrn0zr1/idp/profile/SAML2/Redirect/SSO?. 
   So a reques tis sent to above URL.

*8.* The response is giving the standard SAML HTML Form , which automtically
posts to  "https://vmah-cfd09/Shibboleth.sso/SAML2/POST" using JS. 

*9.* Then it repeats the step 1. 

The above step continues from Step 1 to 9,  and it hangs the browser.
