nebeans不会为h2创建逆向工程文件

I am newbie to h2 database.I have created some tables in h2 using browser console. when i try to create the hibernate.cfg file it creates like below.

我是h2数据库的新手。我使用浏览器控制台在h2中创建了一些表。当我尝试创建hibernate.cfg文件时,它创建如下。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">org.h2.Driver</property>
    <property name="hibernate.connection.url">jdbc:h2:~/selva</property>

  </session-factory>
</hibernate-configuration>

But when i try to create a reverse engineering i got the below error.

但是当我尝试创建逆向工程时,我得到了以下错误。

why it happens?.Netbeans create reverse enginnering file for mysql and mssql databse.But why not create the h2?

它为什么会发生?.Netbeans为mysql和mssql数据库创建反向工程文件。但为什么不创建h2?

Cannot establish database connection with selected Hibernate Configuration file. Please verify the database connection details in hibernate.cfg.xml.

1.How to solve the above issue?
2.Is Querying  inmemory database in hibernate is different from the persistent database?
2.Is Configuring inmemory database in hibernate  is different from the persistent database?

Any help will be greatly appreciated!!!

Click File > New Project

单击文件>新建项目

Select Java Web Application

Then you must be able to do database operations from Netbeans.

然后,您必须能够从Netbeans进行数据库操作。

Click the project select New > Other > Hibernate > Hibernate Reverse Engineering Wizard > then name > then hibernate.cfg.xml > finish

单击项目选择New> Other> Hibernate> Hibernate Reverse Engineering Wizard>然后命名>然后hibernate.cfg.xml>完成

Then you must see hibernate connection properties in the cdg file.

When Netbeans makes connection to db it will takes some time or some blinking, then you are making the correct move.

当Netbeans连接到db时,它需要一些时间或一些闪烁,然后你正在进行正确的移动。
