oracle 断口1521默认的吗
tomcat我用的是80
这个类没问题笆
public class DatabaseConn {

public static synchronized Connection getConnection() throws Exception{

try{

Context initCtx = new javax.naming.InitialContext();
Context envCtx=(Context)initCtx.lookup("java:comp/env");
DataSource ds = (DataSource)envCtx.lookup("jdbc/MyBarOne");
return ds.getConnection();

}catch(SQLException e){
System.out.println("SQLException="+e);
throw e;
}catch(NamingException e){
System.out.println("NamingException="+e);
throw e;
}


}
}
