Subject Re: HTTP status 404
Date Thu, 09 Dec 2010 17:10:13 GMT
Hello everyone,
Thanks for the replies I really appreciate your feedback

I have the structure as the following
webapps
|
filename
    |- filename.htm
*    |-*WEB-INF
            |- web.xml
    |-META-INF
            |-context.xml

after having this structure,I use the following command

CATALINA_BASE/webapps/filename/ jar -cvf filename.war *.*

then I deploy the file in the tomcat manager and I have the following error

HTTP status 404
description the requested resource (/filename/)is not available

I assumed that I don't need the  java classes and lib in the WEB-INF  since
I'm only having single html file with java script, Do you think I need any ?
if so how do I know which files I need ?

 I also extracted the filename.war just to see whats in there and I see only
the filename.htm and the META-INF  there is no WEB-INF it is disappearing

Thanks
Lava
