How to create a multiple wildcard url pattern in web.xml?

Question

How would one route the following path in Jetty ?

/users/user_id/transactions/transaction_id

I tried it this way:

/users/*/transactions/*

But I'm getting an error stating below :

java.lang.IllegalArgumentException: Servlet Spec 12.2 violation: glob '*' can only exist at end of prefix based matches: bad spec "/users/*/transactions"

What is the solution to this ?

In web.xml, if you give an URL pattern like this down below :

    <servlet-mapping>
       <servlet-name>servletName</servlet-name>
       <url-pattern>/users/*</url-pattern>
    </servlet-mapping>

So, the URL pattern /users/* denotes that all those requests will be accepted that starts with /users/ and ends with anything. For example : /users/get/all

But you can't give an URL pattern like /users/*/anything/*/.. which is not allowed.

Too bad! I had no idea it would be impossible.

I have added the pdf. Please refer to it.

If you don't mind working with non-standard Jetty only features, there is a way to use URI Templates or Regex to map servlets (but not via the WEB-INF/web.xml). You interested?

@JoakimErdfelt it would be great if you can share an link with the description of jetty regex map.
