Re: [OS-webwork] Configuration in /WEB-INF

Anthony Eden Wed, 11 Jun 2003 21:07:58 -0700

Read my original message again: this is a problem which exists for loading resources through both classloaders and the servlet context. If you want something which will always work then you must use interval reloading. However this means that you have to have a thread which is running to load the resource at a regular basis and this too can be a problem if you are running in a J2EE container. There is no good solution at this time, i.e. nothing provided by the APIs, but you should probably use something (or at least give users the option to use something).

Sincerely,
Anthony Eden

According to the servlet spec getRealPath() will always return null if
the web application is executing in an non-unpacked war.  So, in general
this is not an option for a servlet or any j2ee application.

Isn't getRealPath() deprecated though?

This is exactly the way SiteMesh does it. Have a look at the

ConfigLoader.

There is an interesting problem with using the ClassLoader or the ServletContext for getting resource data: there is no way using the
APIs

to determine if the resource has been modified.

One workaround is to check the getRealPath() method to see if it is available and use it if it is to build a real file object which you

can
use to determine the last modified date.  Another possibility is to
specify a reload interval for the resource.
Does XWork (and/or WW2) provide either of these methods for
reloading

configuration resources?

Ah, I see. That makes sense. So, you are doing it based on the

servlet
context class loader. Kewl, glad to learn that.

You don't need to open an HTTP connection, rather you can get the
InputStream directly from the servlet context:
InputStream in =
servletContext.getResourceAsStream("/WEB-INF/xwork.xml");

I may just be confused or have missed something, but does
getResource

not just give you the path relative to the doc root? Will you

then

open

it using http? Normally, would you not secure your web-inf from

url

access(for security reasons)? Or is there another method that

would

allow you to actually use File (by getting the servlets

"realpath")?

getRealPath is very bad, what's so wrong with
servletContext.getResource() though?

The hardest problem with that is that you can't use context.getRealPath() to get the location of WEB-INF in an

war

config (per servlet spec). Honestly, classpath is usually the

best
solution.

Guys,

It seems like we are having a lot of problems with finding configuration files in the classpath etc. Also, I dislike putting configuration
files

other than .properties on the classpath. That's why I propose
putting
it
all
(components.xml, xwork.xml etc)under /WEB-INF directly (same as
SiteMesh
for
example).
+1 from me
