APAR status

• Closed as program error.

Error description

• Servlet mappings like the following sample will cause the path
  info to be incorrect.
  
  web.xml:
        <servlet-mapping>
           <servlet-name>MyServlet</servlet-name>
  
  <url-pattern>/test/folder/temp/myapp/docs/*</url-pattern>
        </servlet-mapping>
        <servlet-mapping id="ServletMapping_1047421195717">
           <servlet-name>MyOtherServlet</servlet-name>
           <url-pattern>/test/*</url-pattern>
        </servlet-mapping>
  
  Below is an example of the incorrect path mapping
  
  Get issued for:
  https://localhost:9443/contextRoot/test/folder/tmp/servlet
  Wrong HttpServletRequest information received based on
  url-patterns.
  URI: /contextRoot/test/folder/tmp/servlet
  Context path: /contextRoot
  Servlet path: /test/folder/tmp/
  Path info: /servlet
  With first servlet-mapping removed, correct information
  received.
  URI: /contextRoot/test/folder/tmp/servlet
  Context path: /contextRoot
  Servlet path: /test
  Path info: /folder/tmp/servlet

Problem summary

• ****************************************************************
  * USERS AFFECTED: IBM WebSphere Application Server version 6   *
  *                 users who may define several servlet         *
  *                 mappings with similar paths in URI.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: When there are multiple servlet         *
  *                      mappings defined in web.xml with        *
  *                      similar path (s), path info returns     *
  *                      an incorrect value.                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Webcontainer travels down the path URI (one directory at a
  time) and tries to  match the incoming URI with the defined
  servlet mapping in web.xml.  While doing  this, it should have
  remembered the last best match of a servlet mapping but failed
  to do so. Instead, it kept updating its local servlet path
  index every time a matched directory was found. The remaining
  unmatched information in the URI was then used as path info.
  

Problem conclusion

• The webcontainer has been modified so that it only updates the
  servlet path index if there is a perfect match.  This will
  help returning the correct path info when there are multiple
  servlet mappings with similar URI's paths.
  
  The fix for this APAR is currently targeted for inclusion
  in fixpacks 6.0.2.23 and 6.1.0.11.
