servlet filter not working over virtual directories in tomcat
Hi,
I had configured virtual directories in glassfish3.x over which I could write filters.
For an example I could access files at c:/web from http://localhost/TestApp/web over which I could also place a filter at my web app's web/xml file with
<filter-mapping>
<filter-name>dir_filter</filter-name>
<url-pattern>/web/*</url-pattern>
</filter-mapping>Unfortunately Tomcat 8.0 is not allowing me to write a filter above that. It simply ignores the filters and shows the content in the web directory.
The problem is anybody can access all of the files in the "web" folder.
Any how can we place filter over the virtual directories.
FYI - i have made the web app named "TestApp" and the virtual config is located at "$tomcat_dir/conf/Catalina/localhost" directory with the file name "TestApp#web.xml" file and having the content<?xml version='1.0' encoding='utf-8'?>
<Context docBase="C:/web" debug="0" privileged="true"></Context>

Then maybe try this :
Instead of :
<filter-mapping>
<filter-name>dir_filter</filter-name>
<url-pattern>/web/*</url-pattern>
</filter-mapping>
try :
<filter-mapping>
<filter-name>dir_filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Explanation : in <servlet-mapping> and <filter-mapping>, the <url-pattern> is *relative to
the webapp context*. In your case, because of the way you have configured this, the webapp
has a context of "/TestApp/web". Therefore, if you want the filter to apply to everything
under "/TestApp/web", you have to map it to "/*".
So that, in URL-space, it will apply to "/TestApp/web/*".
The way you originally mapped it above, it would apply to "/TestApp/web/web/*", which is
why it seemed not to be working. The filter was there, but never invoked, because there
was never any request URL matching "/TestApp/web/web/*".
Clearer ?
Note that this is the same as what Mark was saying, only in many more words.

Thank you Mark for replying.

Could not do anything with the above statement. May be an example could suffice.
Somehow could see an example for PreResources in the internet and this is
how I did it without an TestApp#web.xml file in the Catalina/localhost folder.
<Context antiJARLocking="true"
path="/TestApp">
<Resources
className="org.apache.catalina.webresources.StandardRoot">
<PreResources
className="org.apache.catalina.webresources.DirResourceSet"
base="C:\\dir"
internalPath="/"
webAppMount="/web" />
</Resources>
</Context>
This works fine with filters.

Pradyut

Tomcat is doing exactly what you have configured it to do. There is no
Tomcat bug here, just user error.
With a context.xml file named TestApp#web.xml you have a defined a new
web application with a context path of "/TestApp/web" and a docBase of
"C:\web"
The URL pattern therefore needs to be "/*"
If you want to mount "C:\web" inside an existing web application using
the path "/web" then you need to define a PreResources or PostResources
element using the org.apache.catalina.webresources.DirResourceSet
implementation. See
http://tomcat.apache.org/tomcat-8.0-doc/config/resources.html for more
details.
