I've added a RewriteValve in my context.xml, and have a simple rewrite.config with one line: RewriteRule ^/(?:[^/]+/)?(resources/.*)$ /SAPUI5/$1 When requesting a page with the matching URL, a 500 error is returned: java.lang.NullPointerException org.apache.catalina.connector.Request.getContextPath(Request.java:1901) org.apache.catalina.valves.rewrite.RewriteValve.invoke(RewriteValve.java:451) [...] I think the problem lies around line 447 in RewriteValve.java: 447 request.getCoyoteRequest().requestURI().setString(null); 448 CharChunk chunk = request.getCoyoteRequest().requestURI().getCharChunk(); 449 chunk.recycle(); 450 if (context) { 451 chunk.append(request.getContextPath()); 452 } setString(null) sets the MessageBytes type to TYPE_NULL, and (context is true in my case) request.getContextPath() tries to access cleared value, which fails.
