> I would like to see an implementation of ResourceLoader that where you can pass a literal String, and that is the template. Something like this:
> public class StringResourceLoader extends ResourceLoader
> {
> 	@Override
> 	public void init( ExtendedProperties extendedProperties )
> 	{
> 	}
> 	@Override
> 	public InputStream getResourceStream( String s ) throws ResourceNotFoundException
> 	{
> 		return new ByteArrayInputStream( s.getBytes() );
> 	}
> 	@Override
> 	public boolean isSourceModified( Resource resource )
> 	{
> 		return true;
> 	}
> 	@Override
> 	public long getLastModified( Resource resource )
> 	{
> 		return 0;
> 	}
> }
> I tested this and it works, but I am assuming this could be handy for others as well.
> On a side note. Why do you have all this ResourceLoaders and their configuration? Would it not be easier to just create a getTemplate( InputStream ) method, then people can get the inputstream from whereever they want? I had now go through quite some hoops with classloading because I need to use Velocity from a plugin into another system. (For those also struggeling with this, you need to call:
> Thread.currentThread().setContextClassLoader( getClass().getClassLoader() );
> before you create your VelocityContext, and use the ClasspathResourceLoader)
