原文 2014-03-20 12:27:39 1 2 java/ netbeans/ jdbc/ derby/ netbeans-7.4

I developed a project in Netbeans Platform Application ie like Modules. 我在Netbeans Platform Application中开发了一个项目，例如Modules。

When i run my project from Netbeans 7.4, it works fine and doesn't show any DB exception. 当我从Netbeans 7.4运行我的项目时，它工作正常，并且不显示任何数据库异常。

Now i created a installer using Netbeans 7.4 for my project. 现在，我为项目使用Netbeans 7.4创建了一个安装程序。 wen i install it, the DB is also installed but its not recognizing the DB and my connection url is public final static String connectionURL = "jdbc:derby:ProjectDB;create=true;user=user;password=p@ssword"; 我在安装它的同时，还安装了数据库，但是它无法识别数据库，并且我的连接URL是public final static String connectionURL = "jdbc:derby:ProjectDB;create=true;user=user;password=p@ssword"; . 。

When i copy paste the DB alone in a location eg: " d:\\project DB " and change the code as connectionURL = "jdbc:derby:D:\\\\project DB; create=true; user=user; password=p@ss" it works fine. 当我复制时，将数据库单独粘贴到例如“ d：\\ project DB”的位置，并将代码更改为connectionURL = "jdbc:derby:D:\\\\project DB; create=true; user=user; password=p@ss" ，效果很好。 But i need to create along with the installer or want my project to recognize the DB. 但是我需要与安装程序一起创建，或者希望我的项目能够识别数据库。

When i searched i got the below links 当我搜索时，我得到以下链接

很难从您的描述中看出来，但是您能看到Netbeans问题的默认模式吗？

Found the Solution.. 找到了解决方案..

launh or run the project after doing clean Build from the "dist" folder. 在“ dist”文件夹中执行clean Build之后，启动或运行项目。
The new Database will be created in the "dist/project name" and you will get a error "Schema DB doesnt exists". 新的数据库将在“ dist / project name”中创建，并且将出现错误“ Schema DB不存在”。
Now close the application and delete the DB in the "dist/project name" folder and copy-paste the DB(this i did for Derby Database) which you use for your project. 现在关闭应用程序，并删除“ dist / project name”文件夹中的数据库，然后复制粘贴该数据库（我为Derby Database所做的工作）。 And run the application agaiin. 再次运行该应用程序。
