Hi,
My app uses Spring and Jta for database transactions and I am trying some
transaction configuration for my cache to work along with that ,
I am facing a couple of problems when doing that.
1. I saw specific mentions of JBossTransactionManagerLookup being the default
transaction manager of Jboss cache. When using it as
TransactionManagerLookupClass, I get a
java.lang.ClassCastException: org.jboss.tm.TxManager.
When trying to import I saw JBossTransactionManagerLookup available in 2
packages ie, org.jboss.cache.transaction.JBossTransactionManagerLookup and
import org.hibernate.transaction.JBossTransactionManagerLookup. I get a class
cast when using both.
2. When specifying the transactionManagerClass as the
GenericTransactionManager, The application complains of having transaction
Manager already registered to the Dummy transaction Manager. The exception is
binding of DummyTransactionManager failed
javax.naming.NameAlreadyBoundException.
I am not specifying the dummy transaction manager anywhere. When I did step
thru the cache code, i couldnt find any place where jboss cache was setting
this. However when I specify no transactionManagers the actual value set in the
transactionManager of cache class was null. I am very confused. I cant set it
after creation of the cache too as this is not a dynamic property. I am not
sure What I have to do. My configuration setting is very simple
String tmlc = JBossTransactionManagerLookup.class.getName();
configuration.setTransactionManagerLookupClass(tmlc);
configuration.setIsolationLevel(IsolationLevel.READ_COMMITTED);
configuration.setCacheMode(CacheMode.REPL_SYNC);
configuration.setLockParentForChildInsertRemove(true);
configuration.setLockAcquisitionTimeout(15000);
I Saw some other posts mentioning the same problem. I am not sure what is wrong
? Any help to resolve this is much appreciated.
Regards
Sundar
