getNextPathPart

public static java.lang.String getNextPathPart(java.lang.String path,
                                               java.lang.String lastPart)
                                        throws javax.servlet.ServletException

Given a requestUri path, find the next uri "fragment" after the "/lastPart/" one. E.g. given url "/test/abc/travel", and lastPart "abc", this will return "travel". Given lastPart "test" will return "abc". This could be done better using a URITemplate (as RFC6570)

Parameters:

path - the RequestURI to search usually done by calling request.getRequestUri().

lastPart - the previousPart of the path to search after.

Returns:

the next part of the path.

Throws:

javax.servlet.ServletException - if path does not contain lastPart
