Hans Schäfer commented on WICKET-6714:
--------------------------------------

Hi Sven, 

I added a quickstart, a small SpringBoot-Application. Don't take care too much 
about webjars. Webjars just provide resources in META-INF/resources-directories.

What's not working is loading resources using ServletContext#getResource within 
tests if using the default-MockServletContext of WicketTester. 
ServletContext#getResource must load resources from  
META-INF/resources-directories (see 
[https://docs.oracle.com/javaee/6/api/javax/servlet/ServletContext.html#getResource(java.lang.String)]
 but it doesn't inside a "standard" WicketTester.

Creating the quickstart I just thought about the fix. I think, it's just 
changing the directory passed to the MockServletContext from "null" to ".". 
Just take a look at the tests, that I have added to the quickstart. I hope they 
explain detailed enough.

Best regards

Hans

> Hello!
> WicketTester does not provide a useful MockServletContext#getResource(). As 
> WicketTester always instantiates MockServletContext passing a null-Value as 
> path (webappRoot), the method MockServletContext#getResource always returns 
> null, even if a resource in the classpath exists.
> My proposal for the implementation of Method MockServletContext#getResource() 
> is:
> URL result = {color:#000080}null{color};
> {color:#000080}if {color}(name.startsWith({color:#008000}"/"{color})) {
>    name = name.substring({color:#0000ff}1{color});
> }
> if (webappRoot != null) {
>   final File f = {color:#000080}new 
> {color}File({color:#660e7a}webappRoot{color}, name);
> {color:#000080}  if {color}(f.exists()) {
>      result = f.toURI().toURL();
> }
> {color:#000080}if {color}(result == {color:#000080}null{color}) {
>    result = 
> getClass().getClassLoader().getResource({color:#008000}"META-INF/resources/" 
> {color}+ name);
> }
> {color:#000080}return {color}result;
> Best regards
