[JBoss-dev] [JBossCache] - AOPC Ant target question
Hi, I plan on pre-compiling all classes that will be uses in the TreeCacheAop. The issue is that the files are located in different places in the project. In the aopc ant build target how woul I list multiple directories in the src path=/ element? I have tried using ref-id's to path elements and filesets, but I have had no success. Any suggestions?

[JBoss-dev] [JBossCache] - Re: TreeCacheAop questions
Ok, I made a mistake before, and Serialized objects work fine in the TreeCacheAop. But I have another question now. I am having trouble using the org.jboss.aop.standalone.SystemClassLoader in Tomcat. The error is failed to transform TreeCacheAOP with a linked exception to the org.jboss.standalone.SystemClassLoader. I put the jboss-cache, jboss-aop, trove and javassist jar files in Tomcat common lib. Am I missing something in the configuration ?

[JBoss-dev] [JBossCache] - Concurrency Question
Hi, I have a question concerning transaction isolation levels. Using the Serilizable level no write or read locks will be granted to TXN2 until TXN1 releases them. Will the same hold for n number of TreeCache instances in cluster of n machines? In other words, Will TXN1 on node a/b/c on server 1 block TXN1 on node a/b/c on server2? My undertanding of transactions is that it will not prevent read/writes on different machines in a cluster.

[JBoss-dev] [JBossCache] - Fetch state on startup in TreeCacheAOP
Hi, I am working with TreeCache and TreeCacheAOP. I have both configured with the FetchStateOnStartUp set to true. To test both I start one instance of TreeCache and TreeCacheAOP. In my TreeCacheLogs I see that when I start a second TreeCache it is updated from whatever is in the first TreeCache. How ever TreeCacheAOP is not getting any data from the first TreeCacheAOP that was running. Are there any configuration settings that are different for TreeCacheAOP?

[JBoss-dev] [JBossCache] - Synchronizing TreeCache in cluser
Hi, I need to restrict access to the TreeCache in our cluster to ensure that no two updates will occur on the same node at the same time. Is there a mechinism in TreeCacheAOP that handles this? Or would I have to develop my own locking mechanism from JGroups using a class like DistributedLockManager?

[JBoss-dev] [JBossCache] - Interceptors, Cache Loaders
Hi, As a developer, is there ever any reason to work with classes in the TreeCache API like interceptors, cache loaders etc when working on developing a distributed cache? Or is it considered best practice to primarily work with TreeCache class ?

[JBoss-dev] [JBossCache] - Re: JBossCache in Tomcat w/ Transaction Support
Bela, I was able to solve my original problem. I stopped using a JDBCCacheLoader. But I get an entirely different error now. I am using TreeCache, Tomcat add JOTM for transactions on two different JVM's. When the following code is exectued | txn.begin(); | tree.put(node,key,value); | txn.commit(); | I get an error on the second Tomcat install (the TreeCache getting the replication) from org.jgroups.blocks.RpcDispatcher sayinganonymous wrote : failed invoking method commit() should not be called on TreeCache directly and the next line of the stack trace is anonymous wrote : at org.jboss.cache.TreeCache.commit() but the call was made on the usertransaction object in the first Tomcat server.

[JBoss-dev] [JBossCache] - Re: JBossCache in Tomcat w/ Transaction Support
Bela, I isolated the problem (I think). I have two webapps running on two tomcat servers on my machine. The error occurs in webapp_2 when when webapp_1 call utx.commit() on a put(fqn,key,data) into the tree. The error is coming from the org.jboss.cache.interceptors.CacheStoreInterceptor class when it tries to convert the call convertMethodCallToModification(); I am using the JDBCCache loader class with a MySql database. The odd thing is I have the exact same setup in Hibernate (as apposed to standalone in servlets) and the performance is fine. I am working on taking the code out of the webapp and putting together an ant script that will run the entire thing for you.

[JBoss-dev] [JBossCache] - JBossCache in Tomcat w/ Transaction Support
Hi,
I am currently evaluating JBossCache for my company. For our purposes we will
need to use JBossCache inside of Tomcact. For transaction support I have added
the JOTM jar files and used the configuration example from the JOTM docs. In
the JBossCache config file I set the JBossTransactionManagerLookup class to
org.jboss.cache.GenericTransactionManagerLookup which seems to work fine. I
have two instances of tomcat on the same machine for my environment. When I
put objects into the tree with the following code
try {
|ut.begin();
|tree.put(node,currentCount,item);
|ut.commit();
| } catch(Exception e){
| log.error(Error adding to cache,e);
| try{
| ut.rollback();
| }catch(Exception e2){}
|
| }finally{
|//sets ThreadLocal treeCache varible to null
| TreeCacheUtil.closeTreeCacheSession();
|//sets ThreadLocal transaction varible to null
| UserTransactionUtil.transactionDone();
| tree=null;
| ut=null;
| }
from node 1 I get the following error on node
2org.jboss.util.NestedRuntimeException: ; - nested throwable:
(java.lang.Exception: method call _put cannot be converted to a modification)
