WebSphere 7.0 won't run filter for root URL -


i have war file defines filter run on urls:

<!doctype web-app public     "-//sun microsystems, inc.//dtd web application 2.3//en"     "http://java.sun.com/dtd/web-app_2_3.dtd"> ... <filter>     <filter-name>ourredirectservletfilter</filter-name>     <filter-class>com.mycompany.redirectservletfilter</filter-class> </filter> ... <filter-mapping>     <filter-name>ourredirectservletfilter</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping>

the filter designed perform redirects 'convenience' urls corresponding 'actual' url, don't think that's relevant problem.

on websphere 7.0, filter doesn't run requests root url, e.g. /ctxroot or /ctxroot/; instead 404 response. does run /ctxroot/blah, whether blah valid or invalid path.

i've tried adding additional filter mappings url patterns <url-pattern>/</url-pattern> , <url-pattern></url-pattern>, same behavior.

i've tested on base 7.0.0.0, , latest fix pack applied, i.e. 7.0.0.27.

the filter works expected on 8.5 , i'm pretty sure on 8.0, on every version of weblogic, jboss, , tomcat i've tried. seems bug 7.0, i'd still find workaround. know of one?

i looked @ body of 404 error response , saw error code srve0190e, led me this helpful page. issue filters aren't called default urls correspond resources don't exist (though swear tested url other context root, , filter called).

it's possible configure websphere call filters in situation setting custom property further described in linked page:

com.ibm.ws.webcontainer.invokefilterscompatibility=true

i found case of context root url, setting welcome-file entry in web.xml maps existing resource causes filter called:

<welcome-file-list>     <welcome-file>fakehome.html</welcome-file> </welcome-file-list>
