[jboss-user] [JBoss Cache: Core Edition] - ] No transaction manager lookup class has been defined. Tran
Hallo!
With JBoss 3.2.7, JBoss Cache 1.2,
treecache-service.xml:
<server>
|
| <classpath codebase="lib" archives="jboss-cache.jar,
jgroups.jar"/>
|
|
| <mbean code="org.jboss.cache.TreeCache"
name="jboss.cache:service=TreeCache">
| <depends>jboss:service=Naming</depends>
|
| <depends>jboss:service=TransactionManager</depends>
|
|
| <!-- Configure the TransactionManager -->
| <attribute
name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute>
| <!--
| Node locking level : SERIALIZABLE
| REPEATABLE_READ (default)
| READ_COMMITTED
| READ_UNCOMMITTED
| NONE
| -->
| <attribute name="IsolationLevel">REPEATABLE_READ</attribute>
|
| <!-- Valid modes are LOCAL
| REPL_ASYNC
| REPL_SYNC
| -->
| <attribute name="CacheMode">REPL_ASYNC</attribute>
|
| <!-- Name of cluster. Needs to be the same for all clusters, in order
| to find each other -->
| <attribute name="ClusterName">TreeCache-Cluster</attribute>
| ....
|
I get
16:08:55,724 WARN [TreeCache] No transaction manager lookup class has been defined.
Transactions cannot be used
When I use
<attribute
name="TransactionManagerLookupClass">org.jboss.cache.JBossTransactionManagerLookup</attribute>
| instead of the DummyTransactionManagerLookup
I get
13:20:35,493 ERROR [TreeCache] Starting failed jboss.cache:service=TreeCache
| java.lang.ClassNotFoundException: No ClassLoaders found for:
org.jboss.cache.transaction.GenericTransactionManagerLookup
| at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:275)
|
Which TransactionManagerLookup am I supposed to use to make Transactions work?
What is this Dummy supposed to do? In an example configuration in the documentation for
JBoss Cache 1.2 the Dummy is used ( ????? ).
Thanks for any advise.
Hans
