Any way to disable caching in embedded mode?
Hello,
As I develop with Felix embedded in my host application, I find I have to
set a new value for this line of code
configProps.setProperty(BundleCache.CACHE_PROFILE_PROP,
"testdir53");
every time I make a change to my bundle, which is pretty much every
change-compile-test iteration. Pretty painful. Either that, or go and delete
the .felix directory's contents.
Is there any way around this? I didn't see any way to do so on
http://felix.apache.org/site/apache-felix-usage-documentation.html and a
google search didn't turn anything up.
Thanks,
Jared

Deleting the directory worked nicely. Thanks to both of you.
private static void setupCache(Properties configuration) {
// Create the cache directory.
File cacheDir = new File(SystemUtils.JAVA_IO_TMPDIR, ".felix");
if (!cacheDir.exists()) {
boolean madeDir = cacheDir.mkdir();
if (!madeDir) {
Log.log("Failed to create " + cacheDir);
}
}
// We don't want Felix caching old copies of bundles -- we want to
start
// from a clean slate each time, so delete its contents now.
try {
cleanDirectory(cacheDir);
} catch (IOException ex) {
Log.logException(ex);
}
// Explicitly set where we want bundles to be cached
// http://cwiki.apache.org/FELIX/apache-felix-bundle-cache.html
configuration.setProperty(BundleCache.CACHE_PROFILE_DIR_PROP,
cacheDir.getAbsolutePath());
}

Felix doesn't automatically delete the cache. If you want to do that,
just modify your application launcher to delete the directory when it
completes, as Karl mention belows. Another option, for debugging
purposes is to install your bundle JAR file by reference (e.g.,
"reference:file:/path/to/bundle.jar"), which will not copy the bundle
into the cache, but will use it directly from the specified
location...this approach does have some limitations, but it may help you...

Well, you could just update you bundles from inside your application
on startup or since you set a specific dir you could just delete that
one on application shutdown no?
