          Severity: normal

            Status: NEW

Example

Hi,

According to Servlet Specification, Servlet container should serve static
resources and jsp files, located in META-INF/resources in any jar file under
WEB-INF/lib.

"
10.5  Directory Structure
A Web application exists as a structured hierarchy of directories. The root of
this hierarchy serves as the document root for files that are part of the
application. For example, for a Web application with the context path /catalog
in a Web container, the index.html file at the base of the Web application
hierarchy or in a JAR file inside WEB-INF/lib that includes the index.html
under META-INF/resources directory can be served to satisfy a request from
/catalog/index.html. If an index.html is present both in the root context and
in the META-INF/resources directory of a JAR file in the WEB-INF/lib directory
of the application, then the file that is available in the root context MUST be
used.
"

When requesting such static resource/jsp file, Tomcat returns 404 Not Found.

Example is attached.
Request:
http://localhost:8080/test-meta-inf-resources/test.jsp
http://localhost:8080/test-meta-inf-resources/meta_inf_resource.jsp

After investigating the issue I think that the problem is in the following
code:
org.apache.catalina.startup.ContextConfig
protected void processResourceJARs(Set<WebXml> fragments) {
...
    if (jar.entryExists("META-INF/resources/")) {
        context.addResourceJarUrl(url);
...
}

When I list the entries in jar, I receive:
INFO: Deploying web application archive
C:\apache-tomcat-7.0.29\webapps\test-met
a-inf-resources.war
 META-INF/MANIFEST.MF
 META-INF/resources/meta_inf_resource.jsp

There is no entry "META-INF/resources/"

I would like to propose a patch (attached) with which the request URLs above
are working as expected.

Best Regards
Violeta Georgieva
