javascript Error : Dojo is undefined

Hi,
My application is using both, in one module struts1 and in other module struts2. i have to do file uploading in struts1 but due to struts2 filter mapping as given below
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Struts1 considering the multipart request as the http request, so i am getting the FormFile always Null. To solve this problem, I have changed <url-pattern>.action</url-pattern>, Now my problem of file uploading is solve, But it has created new problem in struts2 module while travercing the module, I for the javascript exception "Dojo is undefined". I am not getting any solution to solve this problem. i can not convert back url-pattern to / if do this my file uploding will not work.

Request you to send me solution As early as possible
