url-pattern algorithm problem?
Hello,
We are using Tomcat 7.0.11 with the following servlet-mapping
<servlet-mapping>
<servlet-name>app</servlet-name>
<url-pattern>*.htm</url-pattern>
<url-pattern>/en/*</url-pattern
</servlet-mapping>
The problem we find if the incoming url is like
"http://example.com/en/yp/list/cat/10/1", it will not matched to the
'app' servlet. Any ideas? Could it be a problem in tomcat matching
algorithm?
Regards,
Cha

My bad, the app is deployed as 'ROOT' and I did read the url-pattern
section in the section before posting the question.
Based on what I read, it should match to the 'app', but it is not in
this case.

Likely correct behavior, since neither of your specified patterns match the incoming URL - if your webapp is deployed as "en". The above pattern would only match the URL if your webapp is deployed as "ROOT" - but you didn't tell us.

Read the servlet spec; the <url-pattern> does *not* include the context (webapp) name.

Below are all the url patterns that we have.
<servlet-mapping>
<servlet-name>app</servlet-name>
<url-pattern>*.htm</url-pattern>
<url-pattern>/en/*</url-pattern
<url-pattern>/zh_TW/*</url-pattern>
<url-pattern>/zh_CN/*</url-pattern>
</servlet-mapping>
Here is the url http://example.com/en/yp/list/cat/10/1 that doesn't work
for the above patterns. Like I said if I changed one of the above
url-pattern to /en/yp/*, this url will work.

Sounds like you have another conflicting <url-pattern> somewhere in
web.xml. Care to post the rest of your <url-patterns>?

So, such patterns do work, but that specific one does not.
I guess it will be something trivial, like mapping two different
servlets to the same URL pattern.
If you want to debug it, look at
http://wiki.apache.org/tomcat/FAQ/Developing#Debugging
and place breakpoints in the
org.apache.tomcat.util.http.mapper.Mapper
class.

'>' is a copy&paste error sorry. Yes, I do have filters but there is
not url rewrite at all.
Turning on the debug on tomcat, it is return 404.
If I changing the pattern to /en/yp/* for that incoming url, it will
work but it doesn't conform to what the spec said though.

Cha.

Missing '>'.
Do you have a Filter that catches such requests and rewrites the URL?
If you do, then the request will never reach the servlet.
