Re: configuration derby plugin for eclipse

[Charlie Kelly]

Hi Fernando,

I use Eclipse with Derby and Hibernate.
I find it helpful to create a project that has all the jar files needed 
by Derby, Eclipse, and other programs (for example, Velocity).
You can use Eclipse's wizard to create a plugin from existing jar 
archives (File->New->Project->Plugin Development->Plugin from existing 
jar archives).

You can create a properties file and folder in your plugin and access it 
with code that is similar to the following:

           hibernatePropertiesPlugin = 
MetaPersistenceActivator.getDefault();
           String propertiesFileNameFQ = "properties/hibernate.properties";
          
           Path hibernatePropertiesPath = new Path(propertiesFileNameFQ);
           Bundle hibernatePropertiesBundle = 
hibernatePropertiesPlugin.getBundle();
          
           URL hibernatePropertiesURL  = FileLocator.find 
(hibernatePropertiesBundle, hibernatePropertiesPath, null);
           if (null == hibernatePropertiesURL)
               throw new Exception ("URL is null for: " + 
propertiesFileNameFQ);

           boolean substituteArgumentsFlag = false;
           InputStream hibernatePropertiesInputStream = 
FileLocator.openStream(hibernatePropertiesBundle, 
hibernatePropertiesPath, substituteArgumentsFlag);
           int availableBytes = hibernatePropertiesInputStream.available();
           if (availableBytes <= 0)
               throw new Exception ("nothing available from 
properties/hibernate.properties");           
          
           hibernateProperties.load(hibernatePropertiesInputStream);

Use the name of the Activator for your plugin instead of 
"MetaPersitenceActivator"
"Path" is contained in org.eclipse.core.resources (which you must 
include as a dependency for your plugin).

Hope this helps.

Hi People,

but, I forgot a detail, 

I am eclipse user and I am using the derby like plugin (bundle).

So , I don't know where the files was created.

Can you help me?

In this case (derby plugin for eclipse)

1) How could I use some file xml or another configuration file 
configure the database, like to choose the place that I will create my 
Database's instance.

2) Where Derby save your files of database.?

Thanks and Best Regards
