Method Detail

getBundleInstallLocation

public File getBundleInstallLocation(org.osgi.framework.Bundle bundle)
                              throws Exception

Works with equinox, felix, nuxeo and probably more. Not exactly in the spirit of OSGi but quite necessary to support self-contained webapps and other situations.

Currently only works with bundles that are not jar.

Specified by:

getBundleInstallLocation in interface BundleFileLocatorHelper

Parameters:

bundle - The bundle

Returns:

Its installation location as a file.

                            String path)
                     throws Exception

locateJarsInsideBundle

public File[] locateJarsInsideBundle(org.osgi.framework.Bundle bundle)
                              throws Exception

If the bundle is a jar, returns the jar. If the bundle is a folder, look inside it and search for jars that it returns.

Good enough for our purpose (TldLocationsCache when it scans for tld files inside jars alone. In fact we only support the second situation for development purpose where the bundle was imported in pde and the classes kept in a jar.

Specified by:

locateJarsInsideBundle in interface BundleFileLocatorHelper

Parameters:

bundle -

Returns:

The jar(s) file that is either the bundle itself, either the jars embedded inside it.
