Zhang JinYan commented on VYSPER-294:
-------------------------------------
Thanks for your rapid resolution:)
But the resolution still has some problem.
java doc for CacheManager.create(URL configurationFileURL)：
A factory method to create a singleton CacheManager from an URL.
This method is used to initialize the singlton instance.
If CacheManager is initialized somewhere else, then call this method will not
re-initialize the singlton again.
All CacheManager's static method is operating on the singlton.
e.g.
I want to extend Vysper, and i use EhCache too.
I have two EhCache config file: ehcache.xml and ehcache-vysper.xml
("PresenceCache" is configure in this file)
In my extension, i used the default config file: ehcache.xml
And i want config the EhCachePresenceCacheImpl to use ehcache-vysper.xml,
but this make no sense.
When vysper running,exception may throw out: presenceCache is null.
That's why i replace xmpp.patch again and again.
I'm sorry for my stupid operation, make this issue page a mess.
My final patch is :
If the passed in configFile is null, then use CacheManager.getInstance() to
get the singlton directly, which will be initialized with the default
ehcache.xml.
If else, i use the special configFile to create a new CacheManager.
You can find more detail in my xmpp.path file.

>
> 1、The EhCachePresenceCacheImpl has a constructor arg, which specify the
> configFile used to initialize a EhCache CacheManager,but didn't use it at
> last.
> Code:
> protected void createCache(String configFile) {
> if (configFile == null) {
> configFile = DEFAULT_EHCACHE_CONFIG_FILE;
> }
> URL configFileURL = getClass().getResource(configFile);
> if (configFileURL == null) {
> throw new RuntimeException("ehcache configuration file
> ehcache.xml not found on classpath");
> }
> CacheManager.create(); //<============== Here i am!
> presenceCache = CacheManager.getInstance().getCache(PRESENCE_CACHE);
> jidPresenceCache =
> CacheManager.getInstance().getCache(JID_PRESENCE_CACHE);
> }
> 2、dist/src/main/assembly/src.xml
> Didn't excludes .* file/folde in sub directory. If i use eclipse to import
> those projects, there will create .* files (eclipse project files,eg:
> .classpath)
> <excludes>
> <exclude>**/target/**</exclude>
> <exclude>.*</exclude>
> <exclude>.*/**</exclude> //<============== Here i am!
> <exclude>**.bak</exclude>
> </excludes>
> I upload my patch.
