NullPointerException in QuickStart Sample
Hi there,
I want to try JSecurity for the first time. I think I'm doing sth wrong... I want to try the QuickStart in my Eclipse so I added the jsecurity.jar and the QuickStart.java. No errors there. Then I try to start the main()-Method an this ist the Output:

So currentUser.login(token) throws a NullPointerException
What am I doning wrong? Is there a need to put a jsecurity-users.properties somewhere because of Defaulting to failsafe PropertiesRealm?

Solved it by my self. It's
Solved it by my self.
It's obvious to add jsecurity.jar and commons-logging.jar to your classpath.
What I didn't know: you need backport-util-concurrent.jar, ehcahce.jar and xercesImpl.jar, too.
How I figerued that out: I just looked into the build.xml. Everything you need to run the QuickStart-Sample is written there ;)
<include name="ehcache.jar"/>
<!-- needed by ehcache, not jsecurity: -->
<include name="backport-util-concurrent.jar"/>
<include name="commons-logging.jar"/>
<!-- Not normally needed, but mac os x JDK needs it for some reason: -->
<include name="xercesImpl.jar"/>
What's ehcache I asked my self... well "Ehcache is a widely used java distributed cache for general purpose caching, Java EE and light-weight containers." (http://ehcache.sourceforge.net/). Don't need to know more for now.
Keep up the good work and I hope we can get a glimps at the promised Reference-Guide very soon ;)

Sebastian
Re: Solved it by my self.
Hi Sebastian,
Sorry for the confusion. I expect most people to run the quickstart from the command line, as the quickstart document recommends. Since I don't have the time to write setup guides for each IDE (I use IntelliJ IDEA myself), I use ant for the examples since pretty much everyone has that ;)
Regards,
Les
