Embed Derby DB with Netbeans Platform Application - Module

Question

I developed a project in Netbeans Platform Application ie like Modules.

When i run my project from Netbeans 7.4, it works fine and doesn't show any DB exception.

Now i created a installer using Netbeans 7.4 for my project. 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"; .

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. But i need to create along with the installer or want my project to recognize the DB.

When i searched i got the below links

but dint get a solution.

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？

Answer 2

Found the Solution..

• launh or run the project after doing clean Build from the "dist" folder.
• The new Database will be created in the "dist/project name" and you will get a error "Schema DB doesnt exists".
• 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. And run the application agaiin.
