Eclipse RCP中资源的应用程序范围位置在哪里？

Question

I am wrapping some 3rd party application into Eclipse plugin.

This application uses some data files in "current" directory, ie directory where application ran from.

Initially I put all of theses files at first level in Eclipse plugin project and can access these files via

bundle.getEntry("./conf/conf.xml")

unfortunately, this code creates strange URLs like

bundleentry://88.fwk1692538903/./conf/conf.xml

Why is it so? Is it possible to put all application-scoped files into some global location and refer it from a plugin?

Answer 1

Use org.eclipse.core.runtime.FileLocator to convert the bundleentry URL to a normal file URL:

URL bundleURL = bundle.getEntry("...");

URL fileURL = FileLocator.toFileURL(bundleURL);

Note: If the plugin is in a jar rather than expanded during install the URL returned may reference a temporary location in the metadata where the plugin has been expanded.
