Error while trying to persist JPA entity...

rluceac Aug 22, 2011 9:41 AM

Hi, I'm getting an error when I try to persist an entity from a class. I created the class UserController, and when I try to execute the Register method, the em.pertist(usr) line I'm getting an error, when I run this code inside the UserRegBean directly it works... Someone can help me please...

Here are the code:

UserController.java

public Boolean Register(String _userName,String _passwd) throws NoSuchAlgorithmException, UnsupportedEncodingException

{

User usr = new User();

usr.setEmail(_userName);

MessageDigest digest = MessageDigest.getInstance("SHA-1");

digest.reset();

digest.update(pwdSalt);

byte[] input = digest.digest(_passwd.getBytes("UTF-8"));

BASE64Encoder encoder = new BASE64Encoder();

usr.setPassword(encoder.encode(input));

em.persist(usr);

return true;

}

UserRegBean.java

public void register() throws Exception {

UserController uControl = new UserController();

Boolean registered = uControl.Register(this.email,this.passwd);

/* User usr = new User();

usr.setEmail(this.email);

MessageDigest digest = MessageDigest.getInstance("SHA-1");

digest.reset();

digest.update(pwdSalt);

byte[] input = digest.digest(this.passwd. getBytes("UTF-8"));

BASE64Encoder encoder = new BASE64Encoder();

usr.setPassword(encoder.encode(input));

em.persist(usr);*/

}

The Error:
