I'm running into a problem with some code of mine. The following code
takes a list of our main DB users and "pushes" it into the wiki's DB
(currently an XML file). Here is a snippet of my code:
com.ecyrd.jspwiki.auth.user.UserDatabase udb =
engine.getUserManager().getUserDatabase();
for(Map.Entry<String, String> entry :
rc.entrySet()) { //a list of users and emails
String key = entry.getKey();
String value = entry.getValue();
com.ecyrd.jspwiki.auth.user.UserProfile
newP = udb.newProfile();
newP.setLoginName(key);
newP.setFullname(key);
newP.setEmail(value);
udb.save(newP);
}
The problem I am running into is when it runs on a XML file that already
exists (contains hundreds of users) and tries to add new users, the users
go in with a UID of "" (empty string) and the wiki crashes. I'm not 100%
sure that the wiki is crashing due to the empty UID, but it is my only
guess. I see the following stack trace:
java.lang.NullPointerException

I did notice that if I restart the wiki server, the UID's are fixed (have
values) and the app starts working again.
Any thoughts? I'm running 2.8.1 on Windows.
