Summary: Filter not invoked when <location> of <error-page>
contains querystring
Product: Tomcat 6
Version: 6.0.26
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: major
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
The filter is not invoked with the following web.xml:
<filter-mapping>
<filter-name>log</filter-name>
<url-pattern>*.do</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
<servlet-mapping>
<servlet-name>my-servlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.do?type=generic_error</location>
</error-page>
Changing <url-pattern> with <servlet-name> the filter is correctly invoked:
<filter-mapping>
<filter-name>filter</filter-name>
<servlet-name>action</servlet-name>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
The filter is also correctly invoked using <url-pattern> but removing the
querystring from <location>:
<filter-mapping>
<filter-name>filter</filter-name>
<url-pattern>*.do</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.do</location>
</error-page>
I have tested with 6.0.26 and 5.5.28.
The problem seems to be in the class
org.apache.catalina.core.ApplicationFilterFactory.java, method matchFiltersURL,
Case 3 - Extension Match.
