[rules-users] Help needed - Repository not getting initialised?
Hi,
Repository is not getting initialised, throws NPE.
Please advise.
TIA.
public static Repository repository;
public static Session getSession() throws Exception {
return getSession(true);
}
public static synchronized Session getSession(boolean erase) {
try {
if (repository == null) {
if (erase) {
File repoDir = new File("repository");
System.out.println("DELETE test repo dir: "
+ repoDir.getAbsolutePath());
RepositorySessionUtil.deleteDir(repoDir);
System.out.println("TEST repo dir deleted.");
}
JCRRepositoryConfigurator config = new
JackrabbitRepositoryConfigurator();
String home = System
.getProperty("guvnor.repository.dir");
repository = config.getJCRRepository(home);
Session testSession = repository
.login(new SimpleCredentials("alan_parsons",
"password".toCharArray()));
RulesRepositoryAdministrator admin = new
RulesRepositoryAdministrator(
testSession);
if (erase && admin.isRepositoryInitialized()) {
admin.clearRulesRepository();
}
config.setupRulesRepository(testSession);
return testSession;
} else {
return repository.login(new SimpleCredentials(
"alan_parsons",
"password".toCharArray()));
}
} catch (RepositoryException e) {
throw new IllegalStateException(e);
}
