Added: jasper34/liaison/org/apache/jasper34/tomcat33
JspServletInterceptor.java
Log:
Split JspInterceptor's handling of JspServlet.
There are 4 distinct methods of plugging jasper:
- JspInterceptor - use a lot of container internals
- JspServlet, requiring minimal container support ( all in JspServletInteceptor
for tomcat33 )
- JspServlet in the webapp ( with settings in web.xml ) - no support from
the container needed ( except the attributes )
- the 4-th is still on the design stage, but I think it'll be very cool.
Details later.
