Question

I am trying to use Openlayer in a WEB application based on spring framework. I need to use a cgi proxy on tomcat. I followed the instruction here installing-a-cgi-on-tomcat. It works with a simple web application. But I got problem to access the cgi file when I tried to implement it with Spring MVC. I got the warning message.

 WARN org.springframework.web.servlet.PageNotFound:962 - No mapping found for HTTP request with URI [/pcms/app/cgi-bin/proxy.cgi] in DispatcherServlet with name 'Spring MVC Dispatcher Servlet'

I tried many ways,but I didnt figure out how to access the proxy.cgi file under WEB-INF\cgi directory. Please help. Thanks.

Answer 1

You mapped CGIServlet to /cgi-bin/* and DispatcherServlet to /app/* – no surprise that request to <contextPath>/app/cgi-bin/proxy.cgi is handled by Spring rather than by CGI.

Try /pcms/cgi-bin/proxy.cgi instead.
