我有一个简单的应用程序，它使用休眠来处理数据库。当我检查连接和主要方法中的一些方法时，一切都很好。但是当我将它部署在服务器上时，它会抛出
javax.servlet.ServletException: Cant instantiate class: managed.ClientsBean.
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
root cause:
com.sun.faces.mgbean.ManagedBeanCreationException: Cant instantiate class: managed.ClientsBean.
...
root cause:
javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Could not open connection
...
root cause:
org.hibernate.exception.JDBCConnectionException: Could not open connection
root cause
java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost:5432/project
但我也有那个司机jboss\standalone\deployments。我怎样才能让jboss看到它？
