[Springframework-developer] spring-web broken on unix

[Chris S. <ch...@lo...>]

Hi everyone,

Juergen, I've just found a problem with the changes you made to 
XmlWebApplicationContext recently.

When loading the bean config in getInputStreamForBeanFactory(), it 
delegates to the base class AbstractApplicationContext's 
getResourceAsStream() method.  For a config location such as 
"/WEB-INF/test-servlet.xml", that method will try to load it using a 
URL, fail, catch the MalformedURLException, then see if the path is 
relative or absolute.  If relative, it loads it using the overridden 
getResourceByRelativePath().

That all works fine on windows, but on unix, "/WEB-INF/test-servlet.xml" 
is considered an absolute path because it starts with a slash.  The 
context fails to load because it tries to load it as a File rather than 
from the servlet context.

The problem is that we can't tell whether a config location like 
"/WEB-INF/test-servlet.xml" is a path to a file or a resource in the 
servlet context.  I couldn't find it in a brief flick through the 
servlet spec, but I didn't think servlets were allowed to access 
resources outside the servlet container.  If that's the case, then 
XmlWebApplicationContext ought to override getResourceAsStream() with an 
implementation that always loads from the servlet context.

Regards,

Chris
