Servlet Exceptions while trying to run petstore

Hi all,

For the last few days I ve been trying to get petstore working with
geronimo. When I try to access the main page which redirects to the
following URL

http://localhost:8080/estore/control/language?language=English

I get the HTTP ERROR:503 on the page due to Unavailable Exception. Can
anyone help me out here.


Thanks in advance,
Rajesh

Here is the complete stack trace.

Hi Rajesh ,

You need to get ride of the Japanish screen definitions defined by the 
Pet Store Web application. More accurately, drop the element

    <screen-definition url="/WEB-INF/xml/ja/screendefinitions.xml" 
language="ja_JP"/>

defined by petstore.war!/WEB-INF\xml\requestmappings.xml.

Thanks,
Gianny
