JDBC error after call to external Session Bean
I have built a Seam application (v 2.1.1.GA) that includes a registration page for new users. The user credentials (id and password) are validated and persisted through a separate, non-Seam, JEE application, deployed as a separate Jar and included in the ClassPath of my Seam application. The Seam code that calls the JEE stateless session bean looks like this:
@In(required=false)
PersonHome personHome;
@In
Identity identity;
private String username;
public String getUsername() {
return this.username;
}
public void setUsername(String passedUsername) {
this.username = passedUsername;
}
private String password;
public String getPassword() {
return this.password;
}
public void setPassword(String passedPassword) {
this.password = passedPassword;
}
private String verifyPassword;
public String getVerifyPassword() {
return this.verifyPassword;
}
public void setVerifyPassword(String passedVerifyPassword) {
this.verifyPassword = passedVerifyPassword;
}
public String executeUserCredentialAction()
throws NamingException
{
// Confirm that Password has been typed correctly (twice matching)
if (!getPassword().equals(getVerifyPassword())) {
FacesMessages.instance().add("verifyPassword", "Must match password field");
return "failed";
}
// Check for existing account using the same User name;
// if not, save the user credentials and assign SelfServe role
InitialContext ctx = new InitialContext();
CreateSelfServeUser userService = (CreateSelfServeUser) ctx.lookup("usermanagement/CreateSelfServeUserAction/local");
String userCreationResult = userService.registerUser(getUsername(), getPassword());
if (!userCreationResult.equals("success")) {
return userCreationResult;
}
// Store a copy of the User Id in the Person instance
personHome.getInstance().setUserId(getUsername()); // <-- This line fails!
personHome.update();
// Log in with the established User Id and Password
identity.setUsername(getUsername());
identity.setPassword(getPassword());
identity.login();
return "success";
}
The JEE userService (CreateSelfServeUserAction) is a stateless session bean written using JBoss EJB3 support and Hibernate for persistence. The call to userService.registerUser() works correctly but I get a JDBC exception as soon as I try to reference the Seam component personHome on my return. Here is the stack trace.

There seems to be some conflict between the two Hibernate EnitiyManager instances. The strange thing is that this code used to work when the Seam application was built on Seam version 1.2.1.GA. It stopped working when I upgraded to 2.1.1.GA. I wonder if the problem has something to do with changes to the EntityHome baseclass of the Seam Application Framework that were introduced by Seam 2.
Hope someone can see what I am doing wrong.
