java - Filters - Ignore the other requests excluding the welcome file -

i wrote filter decide user landing page before reach welcome-file. welcome-file written in such way takes input filter , navigate user specific page.

my welcome-file tag is...

<welcome-file-list>    <welcome-file>index.jsp</welcome-file> </welcome-file-list> 

and filter configuration

<filter>     <filter-name>landingpagefilter</filter-name>     <filter-class>com.mypack.test.filters.landingpagefilter</filter-class> </filter>  <filter-mapping>     <filter-name>landingpagefilter</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping> 

the above format working whilst every request passing through filter, want avoid. when hit http://localhost:8000/landing should reach filter first time , later if access http://localhost:8000/landing/edit should execute relevant servlet bypassing filter.

i tried <url-pattern>/*/index.jsp</url-pattern> no use. why use because context may vary app same.

use

<url-pattern>/index.jsp</url-pattern>

instead of

<url-pattern>/*/index.jsp</url-pattern>

so filter mapping part become this

<filter-mapping>     <filter-name>landingpagefilter</filter-name>     <url-pattern>/index.jsp</url-pattern> </filter-mapping> 

irrespective of context works because / represents path after context path.

for example if have 2 context paths a , b 2 deployments of same application in server , accessing them using urls

http://localhost:8000/a/

and

http://localhost:8000/b/

then / in url-pattern represents / after context roots a , b. filter executed index.jsp.
