calling getServletContext() in a servlet - how to??
Hello,
I am testing a servlet, just the init() method like this:
public void testPostMethod() throws ServletException
{
InscribeServlet inscribeServlet = new InscribeServlet();
inscribeServlet.init(config);
}
I get a java.lang.NullPointerException when calling getServletContext()...
in the init() method, my servlet calls getServletContext().getRealPath(). I guess there is where the exception occurs. It could also be in a call to get the DataSource via InitialContext. Attached is the stack trace and the init() method of my Servlet.
Does anyone knows what am I doing wrong???? thanks in advance.
Jose

Thanks Vincent,
Well I am going on vacation right now. I will follow your suggestion
when I got back and I will tell you what the error was so that everybody
knows...
Good wishes to anyone wherever in the world you are...

Ok. Here's what I suggest. Try writing another servlet, but a minimal
one that reproduces the problem. Normally, by doing this, you'll find
out that that servlet works, and by diffing with your InscribeServlet
you'll see what was wrong in that one.
The only error I can see below is in TestInscribeServlet. You are using
a ServletTestSuite. This is not needed. This should be used only for
wrapping pure junit TestCase (that's the goal of it!). If you're
extending ServletTestCase (as you are), you can simply remove your
suite() method.
Try it! Maybe it'll help...

Yes, well I am only showing the init() method of InscribeServlet :(
I don't know if I could/should show more. If you think
it could be of any help I will give it another thought ok? :)
... since we both will benefit from doing it, specially me :)
I was thinking it could be a classpath issue. Something that avoids the
ServletRedirector to create the config object. Anyway, I may not
have an idea of what I am talking about. I will keep trying
and if I find out something... I'll tell you
Thanks a lot

If you had asked me, I would have said it isn't possible, seen the
Cactus implementation code! :-)
Would it be possible for you to send us your InscribeServlet and your
TestInscribeServlet code?
The only other option I see is that you happen to have an instance
variable called config that isn't initialized... but then I'm pretty
sure you would have noticed that... ;-)

RE: calling getServletContext() in a servlet - how to??
Posted by Vincent Massol <vm...@pivolis.com>.
Hi Jose,
Hmmm... very strange.
Normally I would have said:
Seen that the implementation of init() is:
public void init(ServletConfig config) throws ServletException {
this.config = config;
this.init();
}
and that line 204 of servlet-api-4 is:
public ServletContext getServletContext() {
return getServletConfig().getServletContext();
}
and that:
public ServletConfig getServletConfig() {
return config;
}
my conclusion is that your InscribeServlet must somehow override the
init(ServletConfig) method and it must not do a super.init(config)...
However, the stack trace says:
> javax.servlet.GenericServlet.init(GenericServlet.java:256)
and line 256 is:
254 public void init(ServletConfig config) throws ServletException {
255 this.config = config;
256 this.init();
257 }
thus it means this.config = config must have been called... So you're
not overriding GenericServlet.init(ServletConfig) or if you do you are
correctly calling super.init(config)...
hmm....
Can you test that config is not null:
public void testPostMethod() throws ServletException
{
assertNotNull("aha config is null", config);
InscribeServlet inscribeServlet = new
InscribeServlet();
inscribeServlet.init(config);
}
Thanks
