Exception in @PostConstruct not sent to the WebContainer
Hi
The problem is simple: if a RuntimeException is thrown on a @PostConstruct method of a JSF managed bean the exception is not sent to the Web tier.
This behaviour does not give the option to handle a 500 error at the web tier level.
The problem is also in JBoss 4.2.2 and I thought 5.0.0 (J2EE 1.5) will solve it.
Glassfish deals better with this situation and gives you the option to handle a 500 HTTP error .
The JSF managed bean:
public class MyBean {
String value;
@PostConstruct
public void load() {
throw new RuntimeException();
}
public String navigate() {
return null;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
The stack trace in JBoss console is:
