tomcat - HTTP Status 405 - JSPs only permit GET POST or HEAD

Question

Since JSP 2.3 (Tomcat 8) only supported method for JSP is GET POST or HEAD:

https://jcp.org/aboutJava/communityprocess/maintenance/jsr245/245-MR3.html http://svn.apache.org/viewvc/tomcat/trunk/java/org/apache/jasper/servlet/JspServlet.java?view=diff&r1=1497877&r2=1497878&pathrev=1497878

But, I suppose, it is a big incompatible change as, for example, for exception handler it is used to forward to JSP for rendering exception and iso JSP view since JSP 2.3 response is:

Method Not Allowed
HTTP Status 405 - JSPs only permit GET POST or HEAD 

description The specified HTTP method is not allowed for the requested resource.
Apache Tomcat/8.0.3

If we use REST and Spring HandlerExceptionResolver in case of exception we bump into this problem for sure. Are there any workaround for this problem (iso change http method type)?

Answer 1

Sorry, there is no workaround (at the moment) for this. My recommendation to the EG was that the handled methods were made configurable. That suggestion was rejected. I suggest you raise this specific issue with them since it is a good argument for making the supported methods configurable on a per JSP (or group of JSPs) basis.

Meanwhile, I'll take a look at making this configurable using some form of Tomcat specific configuration under the bug you raised for this: https://issues.apache.org/bugzilla/show_bug.cgi?id=56568

UPDATE: As of Tomcat 8.0.9 when a JSP is used to generate an error page, any HTTP method will be allowed.
