Newbie Problem with Struts Configuration, I think...
Hi all,
I was wondering whether you could look at this stack trace below and see
if you
see anything that you've encountered before. I'm running Orion Server
1.4.5 and I wouldn't expect there to be a problem with JNDI. (see stack
trace line re: unknown protocol: jndi)
They (Orion) don't specify any setup needed for JNDI to be running as a
service. Furthermore, I've checked the struts-config.xml and it
seems fine. I've pasted it in below the stack trace.
I'd appreciate any help you could offer because I've been wrestling with
this thing for some time now and can't seem to find any
problems. My JSP form action works the same (i.e. breaks) whether I'm
using 'login.do' or '/login.do'.
thanks again,
Darryl

Yes, it's a bug in Orion.
Servlet containers, among other things, provide a class loader for each
web application (so that the classes from WEB-INF/classes and WEB-INF/lib
are visible only within your app). One of the responsibilities of a class
loader is to implement Class.getResource() and
Class.getResourceAsStream() also, so that an application can access
resource files via the classloader. (This is what
java.util.ResourceBundle requires as well).
The class loader that Orion provides is broken because it does not handle
resource loading correctly from JAR files under WEB-INF/lib. The hack
described above takes care of loading this particular file, but that just
defers the problem until you run into it somewhere else.

I searched the newsgroups and found that a number of you have already
encountered and commented on this issue so my apologies for not determining
that before I posted my previous note.
I found I did fix the problem by removing the DTD from struts.jar and placing
it separately in the classpath. This is unfortunately a hack but I'll have to
go with this for now until Orion fixes it... or is it necessarily an Orion
bug? I found one posting that indicated that if you change some Struts code,
it also fixes the problem.
Olli Poyry notes that in ActionServlet.java, if you replace (~line 881):
URL url = this.getClass().getResource(registrations[i+1]);
with:
URL url = getServletContext().getResource(registrations[i+1]);
the dtd is found and everything works. My question is, should Orion work
regardless or would it be better to change Struts as indicated above?
Comments from anyone?
thanks,
Darryl
