Bug ID: 58015
Summary: servlet-api.jar from WAR files not being excluded
Product: Tomcat 8
Version: 8.0.23
Hardware: PC
OS: Linux
Status: NEW
Severity: regression
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: jasonmcint...@carfax.com
tomcat.util.scan.StandardJarScanFilter.jarsToSkip
has the servlet-api and servlet-api* files in the list.
Deploy a war where an "idiot developer" included "servlet-api-2.5.jar" in the
WEB-INF/lib folder. Try and hit a JSP page, and it fails, due to the "The
method getDispatcherType() is undefined for the type HttpServletRequest" error.
Then, rather than redeploying, stop tomcat, go into the
$CATALINA_HOME/webapps/war/WEB-INF/lib/
and remove servlet-api-2.5.jar and start tomcat
You can then hit the JSP pages. Note, to re-verify, delete the work folder,
remove the unpacked war, and try again to recreate the issue. Off hand, it
appears that the jarsToSkip SHOULD be excluding servlet-api-2.5.jar from wars
loaded into it, but it doesn't appear to be behaving.
Note, this isn't related to Bug 57020 - this is entirely on the server side
with a war that worked fine on Tomcat 6 & Tomcat 7. The same war is failing on
tomcat 8 with the above for JSP pages.
