| Re: [jakarta.ee-community] AutoText Completion Issue - CDIBean |
_______________________________________________Hello,
I am new to the world of Java EE. That's why the problem may seem so absurd. However, I couldn't find any solution that works for my problem. My problem is this:
I have a ".xhtml" file. prompts the user to enter a username. I need to print the information entered with the "Login" button on the label under the button. This is a bit silly because I did it for the purpose of learning. but the CDI Bean in "#{...}" is not reachable. How can i solve this. I have searched many forums on the internet.
Error received:
Exception: jakarta.servlet.ServletException: /login.xhtml @14,242 value="#{LoginCDIBean.tcNoInfo}": Target Unreachable, identifier 'LoginCDIBean' resolved to null
Root Cause: jakarta.el.PropertyNotFoundException: /login.xhtml @14,242 value="#{LoginCDIBean.tcNoInfo}": Target Unreachable, identifier 'LoginCDIBean' resolved to null

public LoginCDIBean() {
this.tcNoInfo = "1234567890";
}
public String getTcNoInfo() {
if (Kontrol(tcNoInfo) == true) {
return tcNoInfo;
} else {
return "Hata ";
}
}

this.tcNoInfo = tcNoInfo;
}

Where is my mistake according to these codes? My dependencies:
jakarta.jakartaee-api-9.1.0.jar
GlassFish Server 6.2.5
Apache NetBeans 15
