Hi everyone,
I'm trying to write an action for registering users.
I'm including the simple dev version I'm starting
with. I get null pointer exceptions with
accountExists() and addUser(). Get somebody clue me
in to what I'm doing wrong?
Thanks in advance,
Terry
code and log follows......
public void doPerform(RunData data, Context
context)
throws Exception
{
Log.info("Registering a new user");
TurbineUser user = new TurbineUser();
DBSecurityService dbum = new DBSecurityService();
// get the parameters passed in
String fName =
data.getParameters().get("FirstName");
String lName = data.getParameters().get("LastName");
String uName = data.getParameters().get("UserName");
String email = data.getParameters().get("Email");
String password =
data.getParameters().get("Password");
Log.debug("parameterParser: " +
data.getParameters());
Log.debug("local vars: " + uName + password + fName
+ lName + email);
// set the properties
user.setFirstName(fName);
user.setLastName(lName);
user.setUserName(uName);
user.setEmail(email);
Log.info("checking for user: " + uName);
// check if username already exists
try
{
if (dbum.accountExists(uName))
{
data.setMessage("A user with this user name
already exsits. Please choosea nother name");
data.setScreenTemplate("RegistrationForm.vm");
return;
}
}
catch (Exception e)
{
Log.error("Error checking in username pre-exists",
e);
}
// store the user info
Log.info("Attempting to create user: " + uName);
dbum.addUser(user, password);
// assign role
Group group = dbum.getGlobalGroup();
Role role = dbum.getRole("curriculum_editor");
dbum.grant(user, group, role);
// authenticate
dbum.getAuthenticatedUser(uName, password);
Log.debug("created account: " + user);
}
