test web app

Hi,
 
I have an application and I want to map my servlet to the application's context root, but I do not want to override the "/" mapping for the "default" servlet.
 
It is specified in the Servlet spec that there is a "special" url mapping that can be used for such purposes and it is an empty string ("").
 
I tried several approaches to specify this via web.xml and annotation, unfortunately all of them results in IAE:

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern>  in servlet mapping
 at org.apache.catalina.core.StandardContext.addServletMapping(StandardContext.java:3208)
 at org.apache.catalina.core.StandardContext.addServletMapping(StandardContext.java:3183)
 at org.apache.catalina.deploy.WebXml.configureContext(WebXml.java:1302)
 at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1305)
 at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:855)
 at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:346)


The issue was started as mail thread in the users list - http://marc.info/?t=133883470600003&r=1&w=2


Can you please provide this feature?
Thanks in advance
Regards
Violeta

PP: test application is attached.

Not fixed yet but as an aside you'll need to use <url-pattern></url-pattern> not <url-pattern>""</url-pattern>

Thanks for the report. Fixed in trunk and 7.0.x and will be included in 7.0.28 onwards.
