Hi,
You need to use an inputstream. You can't get to the file itself in an
efficient way. It may be inside a jar because plugins can be a jar too.
To access the Inputstream:
Bundle bundleForPlugin = ...get the bundle for the plugin of interest...
InputStream is = null;
try {
is = FileLocator.openStream(bundleForPlugin, new
Path("velocity.properties"), false);
... load from the input stream ...
} catch (IOException e) {
...either not found, or some error reading...
} finally {
if (is != null)
try {
is.close();
} catch(IOException e) {
}
}

Hello Alex,
you can probably try this
// locate the resource in your plugin
URL resourceUrl =
Platform.getBundle("com.example.plugin").getResource("velocity.properties ");
// return a file path from this url (extract file if necessary
String filePath = FileLocator.toFileURL(resourceURL).getFile();
// use it
velocity.init(filePath);
Hope that helps

Hi,
The only problem with this is if the file is inside a plugin jar (i.e.
the plugin has not been expanded, which is now the preferred way to
package plugins) then this will cause a copy of the file to be moved
into your .metadata location.
Is velocity a class you can't change? If you can, it would be better to
change it to use an InputStream.

If your talking about the Velocity from Apache, there appears to be an init
method that takes a Properties object. Properties has a load method that
takes an input stream. You can use this to load in the properties from the
InputStream and pass it to the init method.

Hi,
Inside of Eclipse, you should only use slash-based path (no windows-like
backslashes).
Then try with pTemplatePath = "Templates/TableTemplate.tpl".
I'm not sure it is the actual cause of your issue, but it's worth trying,

Hi,
Look in your actual physical plugin that is installed and verify the
file is physically there. Maybe your build.properties didn't include
that file in the bin exports.
