Summary: HEAD requests cannot go through request dispatch
include.
Product: Tomcat 6
Version: unspecified
Platform: PC
OS/Version: Mac OS X 10.4
Status: NEW
Severity: normal
Priority: P2
Component: Servlet & JSP API
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
See https://issues.apache.org/jira/browse/GERONIMO-3896
briefly...
tomcat complains:
Servlet.service() for servlet SimpleDispatchServlet threw exception
javax.servlet.ServletException: Original SevletResponse or wrapped original
ServletResponse not passed to
RequestDispatcher in violation of SRV.8.2 and SRV.14.2.5.1
at
org.apache.catalina.core.ApplicationDispatcher.checkSameObjects(ApplicationDispatcher.java:985)
...
The relevant code seems to be in javax.servlet.http.HttpServlet
protected void doHead(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException
{
NoBodyResponse response = new NoBodyResponse(resp);
doGet(req, response);
response.setContentLength();
}
which is fine but
class NoBodyResponse implements HttpServletResponse {
rather than
class NoBodyResponse extends HttpServletResponseWrapper {
The patch attached to the jira issue makes this change and adapts
NoBodyResponse to be a subclass of HttpServletResponseWrapper and the user
reports that it fixes the problem. I don't know if there would be formatting
issues applying the patch to tomcat's copy of the spec classes.
