Creating users during startup with IdentityManager.createUser()
Hello,
I want to create default user accounts (admin/admin, guest/guest) during the startup of my Seam 2.1.2 application. I need to do this with IdentityManager.createUser() because I use a hashed jpaIdentityStore, so I don't want to have to calculate hashes/update import.sql if I change the hashing approach (one point to modify - the hash annotation - and everything works). Here's the code:
@Stateful
@Name("applicationConfiguration")
@Scope(ScopeType.APPLICATION)
@BypassInterceptors
public class ApplicationConfigurationBean implements ApplicationConfiguration {
@Observer("org.jboss.seam.postInitialization")
public void initializeApplication() {
System.out.println("=== APPLICATION STARTUP ===");
System.out.println("Disable security...");
Identity.setSecurityEnabled(false);
try {
System.out.println("Create context...");
Lifecycle.beginCall();
try {
System.out.println("Creating default user accounts...");
IdentityManager im = IdentityManager.instance();
im.createUser("admin", "admin");
im.createUser("guest", "guest");
System.out.println("Accounts created!");
} catch (Throwable t) {
t.printStackTrace();
} finally {
Lifecycle.endCall();
}
} finally {
Identity.setSecurityEnabled(true);
System.out.println("Security restored...");
}
System.out.println("=== APPLICATION STARTUP ====");
System.out.flush();
}
@Destroy
@Remove
public void destroy() {
}
}The accounts are created just fine, but the application throws an exception and JBoss (5.1.0-jdk6) stops it. So I am left with the accounts and a no longer running application. The exception is shown below, but the interesting thing I found is that I can prevent it (and have everything work perfectly) if I leave the LifeCycle.beginCall() open! In other words, If I remove the LifeCycle.endCall() from the snippet above, everything works.
So this post is more in relation to understanding what is going on: if I don't do a beginCall(), Seam fails with No application context active
. If I do, it fails with the exception below. The only way to keep it happy is to change the state in my @Create method and leave it changed. It does not seem right, but it works. Thing is, I need to understand why it works, otherwise I cannot feel safe about my code..
Anyway, here is what Seam complains about when I play nice and leave things as I found them:
