Subject Re: configuration derby plugin for eclipse
Date Thu, 19 Mar 2009 17:42:37 GMT
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 = 
            String propertiesFileNameFQ = "properties/hibernate.properties";
            Path hibernatePropertiesPath = new Path(propertiesFileNameFQ);
            Bundle hibernatePropertiesBundle = 
            URL hibernatePropertiesURL  = FileLocator.find 
(hibernatePropertiesBundle, hibernatePropertiesPath, null);
            if (null == hibernatePropertiesURL)
                throw new Exception ("URL is null for: " + 

            boolean substituteArgumentsFlag = false;
            InputStream hibernatePropertiesInputStream = 
hibernatePropertiesPath, substituteArgumentsFlag);
            int availableBytes = hibernatePropertiesInputStream.available();
            if (availableBytes <= 0)
                throw new Exception ("nothing available from 

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

Hope this helps.
