Tomcat向URL添加上下文路径

Question

In my application every link generated is surrounded by response.ecodeURL. On some servers encodeURL adds the context-path to the URL.

The application is named "appl". Creating a link /a/b/c.jsp creates on DEV-system the url /a/b/c.jsp, on Prod it creates /appl/a/b/c.jsp

The tomcat is behind an Apache Webserver which connects via ajp, not sure if thats a relevant fact.

EDIT: The Webserver isn't relevant. I tried going directly on port 8080 and the same happend again.

<c:url> always pre-pends the context path to URLs: this is standard practice and should always be done. If you are using <c:url> then you shouldn't add your own prefix. Also note that <c:url> runs the URL through HttpServletResponse.encodeURL for you. That method adds URL-based session-tracking information (eg the ";jsessionid" path parameter) if appropriate.

You should always add the context prefix to all URLs, whether you use something like <c:url> or do it yourself. You just shouldn't do both. When you use the ROOT context, the context path with be "" (ie empty string) and nothing will be pre-pended to your URLs.
