Custom Credentials in Seam 3

[jmonteiro]

Hi, is there any way to customize seam 3 credentials object?

I need to add one more attribute to credentials (captcha). I tryed the following code:

@Named("credentials") @SessionScoped
public class Credentials extends CredentialsImpl {
     
     private static final long serialVersionUID = -4377742708407292709L;
     
     private String captcha;

     public String getCaptcha() {
          return captcha;
     }

     public void setCaptcha(String captcha) {
          this.captcha = captcha;
     }

}

But it has a conflict with org.jboss.seam.security.CredentialsImpl @Named annotation. How can i override the credentials.

The short answer is you'll have to Veto it.

The way to do that varies, you could create an extension to do it, I think you can also do it with Seam Config.

This also seems like a bug, those classes should be the default if there isn't another one that satisfies the contract. Could you please add a JIRA (Arquillian test case preferred)?

try add @Specializes to the bean, according to weld doc, it will override and replace the default bean at runtime.

Hi Jorge,

I use @Specialized version of the CredantialsImpl (as suggested by hantsy bay) and it works fine:

@Inject Credentials credentials;

String captcha = ((CustomCredentials) credentials.getCapture;

You can also use @Alternative, as in...

package com.example;

@Alternative
@Named("credentials")
@SessionScoped
public class MyCredentialsImpl extends CredentialsImpl {
    //...implementation
}

and include the following in beans.xml

<alternatives>
    <class>com.example.MyCredentialsImpl</class>
</alternatives>

You may find you need to use this approach if you are running JBoss AS (I'm developing with AS 7). There is a known bug in Weld with the @Specializes annotation, specifically, deployment fails when the annotated class specialises a class in a different archive (as is the case with Seam Security). See https://issues.jboss.org/browse/WELD-912 for more info.
