Re: JCS.setConfigFilename

[Mauro S. Asprea]

Yes Jorge, the objects must be Serializable. Thanks!

Hi Mauro,

What do you want to achieve?

Why is MaxObjects=0 ? http://jakarta.apache.org/jcs/RegionProperties.html

I would assume that if you are using auxiliaries, that the elements you

want to cache must implement the Serializable interface.

Thanks Jorge it worked :)
Now I have another issue. JCS isn't caching anything...
My config is as following

    ##############################################################
    ##### Default Region Configuration
    jcs.default=DC

jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttribut

es
    jcs.default.cacheattributes.MaxObjects=0

jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory

.lru.LRUMemoryCache

    ##############################################################
    ##### CACHE REGIONS
    jcs.region.myRegion1=DC

jcs.region.myRegion1.cacheattributes=org.apache.jcs.engine.CompositeCach

eAttributes
    jcs.region.myRegion1.cacheattributes.MaxObjects=0

jcs.region.myRegion1.cacheattributes.MemoryCacheName=org.apache.jcs.engi

ne.memory.lru.LRUMemoryCache


    ##############################################################
    ##### AUXILIARY CACHES
    # Indexed Disk Cache

jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheF

actory

jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.Indexe

dDiskCacheAttributes
    jcs.auxiliary.DC.attributes.DiskPath=c:/Developing
    test/NNTPSync/etc/cache
    jcs.auxiliary.DC.attributes.MaxPurgatorySize=10000
    jcs.auxiliary.DC.attributes.MaxKeySize=10000
    jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000
    jcs.auxiliary.DC.attributes.OptimizeOnShutdown=true
    jcs.auxiliary.DC.attributes.MaxRecycleBinSize=7500

I'm calling the cache like this:

    JCS.setConfigFilename("/cache.ccf");
    cache = JCS.getInstance("myRegion1");
    IElementAttributes attributes = cache.getDefaultElementAttributes();
    attributes.setIsEternal(true);
    attributes.setIsSpool(true);
    cache.setDefaultElementAttributes(attributes);

Logging the put and gets and printing the keys I realize that isn't working. Example of my output:

    get() :: news.nkt:::nkt.company.blog //Did'n found becose is first
time
    get() :: news.nkt:::listNewsgroups()  //Did'n found becose is first
time
    put() :: news.nkt:::listNewsgroups() //First cache.put
    get() :: news.nkt:::listNewsgroups()
    put() :: news.nkt:::nkt.company.blog
    [...Output the data I'm retriving...]
    //the second round where all must be cached, without stop the
    aplicattion
    get() :: news.nkt:::nkt.company.blog //this cache.get retrieves
    null, should be cached already
    get() :: news.nkt:::listNewsgroups() //this cache.get retrieves
    null, should be cached already
    put() :: news.nkt:::listNewsgroups()
    get() :: news.nkt:::listNewsgroups()
    put() :: news.nkt:::nkt.company.blog
    [...Output the data I'm retriving...]

I wonder if the object to be cached must be of some particular type, maybe they must implement some interface?

Thanks!

JCS looks for the file at the root of the classpath.

If your code compiles to the directory  "classes\com\nektra\
...\MyClass.class", then make sure the file cache.ccf is located right
under "classes\"

If you are creating a JAR file with your classes, include the

cache.ccf

in the top directory.

Hi, I'm having aa issue when trying to set the config.ccf file path.
My code is:

                    JCS.setConfigFilename("cache.ccf");
                    cache = JCS.getInstance("default");

And I'm getting the following exception

    Failed to load properties for name [cache.ccf]
    java.lang.IllegalStateException: Failed to load properties for

name

    [cache.ccf]
        at

org.apache.jcs.engine.control.CompositeCacheManager.configure(CompositeC

acheManager.java:242)
        at org.apache.jcs.JCS.ensureCacheManager(JCS.java:102)
        at org.apache.jcs.JCS.getInstance(JCS.java:64)

I tried setting the JCS.setConfigFilename with a absolute path like "c:\mydir\mifile.ccf and the exception keeps throwing.

So I donwloaded the code of JCS and noted that the CompositeCacheManager.configure didn't read for my dir path. How can I

make him to read the file from I want to , or where in my project dirs

I

have to put the config file?

I don't how to solve this... any clue?

Thanks!
