Using regular expressions for filter-mapping

Question

I know I cannot use regular expressions for the url-pattern of a filter-mapping, but I wanted to know if it is possible somehow to map the filter using something like /foo/.+/*

Answer 1

No. As to wildcard matching, the <url-pattern> only supports prefix (/folder/*) or suffix (*.extension) matching.

If you want more finer grained matching like as possible with Apache HTTPD's mod_rewrite, then use Tuckey's UrlRewriteFilter or OCPSoft Rewrite instead. They support mod_rewrite-like expressions by XML configuration.

Answer 2

No. URL Patterns in Servlet does not support regular expressions. They can be only of these below three types:

• Exact Pattern For Ex, /folder/abc.html, /folder/abc
• Directory Pattern For Ex, /folder/abc/*
• Extension Pattern For Ex, *.js, *.reports etc
