.war Dosyasının Dağıtılmasından Sonra, Glassfish'te Veritabanına Bağlanamadı

Question

Üniversitedeki Java-EE için çok yeni ve Netbeans IDE'de veritabanı bağlantısıyla mükemmel bir şekilde çalışan projemi yapmaya çalışıyorum. NetBeans IDE (sunucu başlangıç ​​etki alanı etki alanı ve * .war dosya uygulama listesinde) ile başlatıldı ve sonra ben * .war dosya yerel ana sunucuya dağıtmak için çalıştı. projeyi localhost'ta başlatın: 8080, veritabanı bağlantısı başarısız oldu ve web uygulamam işe yaramayacaktı.

Bunu çözmek için herhangi bir fikri olan var mı? Exception picture

public DataSource getDataSource(){

} 
} 

Answer 1

aşağıda arama sözdizimi değişen deneyin:

ds = (DataSource)ctx.lookup("java:jdbc/fastfood"); 

Answer 2

Java EE size arama olmamalı siz el ile bağlantı kurarsınız ama bir veri kaynağı kullanın (https://docs.oracle.com/javase/8/docs/api/index.html?javax/sql/DataSource.html) uygulama sunucunuzda yapılandırıldı.

Veri kaynağını daha sonra burada açıklandığı gibi bileşeninize enjekte edebilirsiniz: https://docs.oracle.com/javaee/6/tutorial/doc/bncjk.html. Alternatif olarak veri kaynağını elde etmek için bir JNDI araması yapabilirsiniz.

bağlantınızın persistence.xml kendi JNDI adını vererek kazanılmış olacaktır veritabanı erişimi için JPA kullanıyor ve sadece @PersistenceContext açıklama (https://docs.oracle.com/javaee/7/api/javax/persistence/PersistenceContext.html)
