I POST data and the URL shows Query String. Why?

Hi,

When I post a data using urlencoded-post method in the submssion tag, the data reaches my webserver correctly. However, the URL of the page shows a query string like this: http://mydemoapp.bpapps.com/mobile/login?....amp;.lang=en-in

I am using struts2 to read the data at the backend and therefore its generating :

WARNING: Error setting expression '.intl' with value '[Ljava.lang.String;@1f2f70a'
ognl.ExpressionSyntaxException: Malformed OGNL expression: .intl [ognl.ParseException: Encountered " "." ". "" at line 1, column 1.
Was expecting one of:

"not" ...
"+" ...

"!" ...
"(" ...

Can you tell me why the URL shows the query string?

Thanks

I finally could make my app work by using a servlet filter and modifying the .ts to ts ; .intl to intl and .lang to lang in the requestParamMap. Then struts works normally. Struts fails to parse anything starting with a dot (.) and that was the problem. But still, I would like to know why the POST request also creates a query string...wats going on inside? Please explain.

I need some more information before I can help. Your page returns a 404 now. Can you post the raw response you are getting?

I think the framework Ratnadeep is using (OpenSymphony) cannot deal with unexpected key-value pairs in the queryString.
As I can tell from the exception trace, it is trying to map/compile the values to some internal datastructure using OGNL (Object-Graph Navigation Language).

So, my take on the question is why the Blueprint server adds these key-values pairs , even to a application specifc queryString, instead of only putting them in Http headers (http://developer.yahoo.com/mobile/blueprint/BP_HTTP_Headers.html)
