I guess I had to make the methods public but still how do I configure what I am after?

[jboss-user] [JBoss Cache: Core Edition] - Re: Multiple Cache Loaders
OK I have tried to extend the FileCacheLoader and use that to test what I am
after. The issue is that I have break points on isCharacterPortableTree and
isCharacterPortableLocation but I am not hitting either method and I don't
understand why. I know my class is being loaded as I also put a break point in
the constructor. But my get, puts or isCharacterPortableLocation methods are
never called.
I was hoping to do this and test my case mentioned above to ignore a specific
region in this cacheLoader. Basically I don't want one of the regions in disk
cache but only memory cache.
My config is as follows
| READ_COMMITTED
|
|
|
|false
|
| com.dotmarketing.business.TestLoader
|
| location=/Users/jasontesser/dev/dotcms/trunk/cachetest
| check.character.portability=true
|
| false
| true
| false
|
|
|
|
And my class
| public TestLoader() {
| super();
| }
|
| @Override
| public Map get(Fqn fqn) throws Exception {
| // TODO Auto-generated method stub
| return super.get(fqn);
| }
|
| @Override
| public void put(Fqn arg0, Map arg1, boolean arg2) throws Exception {
| // TODO Auto-generated method stub
| super.put(arg0, arg1, arg2);
| }
|
| @Override
| public Object put(Fqn arg0, Object arg1, Object arg2) throws Exception {
| // TODO Auto-generated method stub
| return super.put(arg0, arg1, arg2);
| }
|
| @Override
| public void put(Fqn fqn, Map attributes) throws Exception {
| // TODO Auto-generated method stub
| super.put(fqn, attributes);
| }
|
| @Override
| public void put(List arg0) throws Exception {
| // TODO Auto-generated method stub
| super.put(arg0);
| }
|
| protected boolean isCharacterPortableLocation(String fileAbsolutePath) {
| if(fileAbsolutePath.indexOf("VelocityCache")>-1){
| return false;
| }
| return true;
| // return super.isCharacterPortableLocation(fileAbsolutePath);
| }
|
| protected boolean isCharacterPortableTree(Fqn fqn) {
| List elements = fqn.peekElements();
| // Don't assume the Fqn is composed of Strings!!
| for (Object anElement : elements){
| if(anElement.toString().contains("VelocityCache")){
| return false;
| }
| }
| return true;
| // return super.isCharacterPortableTree(fqn);
| }

[jboss-user] [JBoss Cache: Core Edition] - Re: Eviction Policy Config not working
Well it was firing. I think the issue though I am testing now is that I thought the objects within the FQN were nodes. They don't seem to be though. So I had a FQN which I put a bunch of objects inside. It is all one node though. I was confused here. My question would now be what is the best way to handle this? Do I need a separate node for every object? That seems kind of dumb as all my nodes and keys would be the same.

For what it is worth now I changed the _default_ region to maxNodes = 1 and it still caches more. I do have the 1 so it should be firing i think Anybody know what is happening?

[jboss-user] [JBoss Cache: Core Edition] - GenericTransactionManagerLookup Confussion
Our app is running in tomcat 6. I am trying to set up the transaction manager in Jboss Cache. I am getting the 2008-07-24 19:38:34,315 ERROR [main]org.jboss.cache.transaction.DummyTransactionManager - binding of DummyTransactionManager failed javax.naming.NamingException: Context is read only error which I know is because Tomcat's JNDI is readonly. Can the GenericTMLookup be used without it trying to load the Dummy guy which I know is for unit testing? 1. What is the right way to do this? 2. Do I need the Transaction Manager?

[jboss-user] [JBoss Cache: Core Edition] - Re: Best use of Jboss Cache Implementation
Uhmm by group though I didn't mean server's (buddies) I meant an array of
Strings which work as a way of removing etc... all objects with that group.
Like a tag. OSCache uses that instead of the FQN but it takes a String[] of
them.
So I am not sure what the best practice way to do this with Jboss Cache is. It
seems each object can have a single FQN. it may get built as a b tree so a/b/c
but this is a little different.
In OSCache say I have 2 objects. One in String["c"] group and another in
String["b", "c"] group. I can say cache.remove("c") and both objects would be
removed.
Our primary cache singleton interface has methods like this on it.

[jboss-user] [JBoss Cache: Core Edition] - Best use of Jboss Cache Implementation
I am migrating our app from OSCache to Jboss Cache. In OSCache we had a singleton CacheAdmin interface with methods for put, get remove etc... It would stick all the objects in a single cache. The put method signature looks like put(String key, Object content, String[] groups); You can then flush based on group, key etc... So I have 2 questions. 1. Is having a singlton Cache in jboss cache where all objects get cached ok? or is this bad practice? 2. Can I use the FQN's to accomplish what the groups did? actually what would the best way to do this be is what I am asking.

[jboss-user] [JBoss Cache: Core Edition] - Purpose of cache loader
I am evaluating Jboss cache and I am confused about exactly what the cacheloader is. It seems the only good cache loaders are jdbc ones as the file one is not recommended for production. The api refers to the cache loader as for secondary storage. What exactly is meant by secondary storage in this case? When would cache lookups goto db? Is there a good file store I can use? I was hoping to get the cache on disk.
