Configuration problems using Jboss Pojo Cache 3.0.0.GA

[chandu2708]

Hi There,

  Im trying to configure the pojo cache in my application below is the code im using to register the pojo cache

PojoCache cache = PojoCacheFactory.createCache("META-INF/replSync-service.xml",true);

   Im getting following exceptions when running the above initialization

23:17:26,648 ERROR RootElementBuilder:137 - Configuration warning: cvc-elt.1: Cannot find the declaration of element 'server'.
23:17:26,707 ERROR RootElementBuilder:110 - org.jboss.cache.config.ConfigurationException: Incorrect configuration file. Use '-Djbosscache.config.validate=false' to disable validation.

These are caused by the fact that the configration file you are using are in an older Jbosscache format, and it is not a problem as jbosscache is configured to failback to the 'old' parser that knows how to handle this stuff.

These can be avoid by removing the associated jgroups attributes(e.g. remove attribute max_xmit from element name NAKACK), as jgroups deprecated these attributes from one release to the other.

these looks to me like UDP (the trasnport) tries to bind to 224.0.75.75 on several NIC(net4, net33, net49, net50). The bind operation fails. the transport tries to bind to that address because because you have enable_diagnostics turned on.

Hi Markus,

   I have simplified the configuration to test some basic stuff. and im getting following warning when im trying to use the PojoCache

21:19:55,099  WARN GenericTransactionManagerLookup:114 - Falling back to DummyTransactionManager from JBossCache

 

Could you tell me why the Falling back to DummyTransactionManager is happening please. is there anything im missing in the configuration? please find my cache configuration as below

<?xml version="1.0" encoding="UTF-8"?>

<server>
   <mbean code="org.jboss.cache.jmx.CacheJmxWrapper"
          name="jboss.cache:service=TreeCache">
      <depends>jboss:service=Naming</depends>
      <depends>jboss:service=TransactionManager</depends>
      <attribute name="TransactionManagerLookupClass">org.jboss.cache.transaction.GenericTransactionManagerLookup
      </attribute>
      <attribute name="IsolationLevel">REPEATABLE_READ</attribute>
      <attribute name="CacheMode">LOCAL</attribute>
      <attribute name="LockAcquisitionTimeout">15000</attribute>
   </mbean>
</server>

 

Thank you,

bala.

The purpose of the TransactionManagerLookup is to lookup an javax.transaction.TransactionManager within your runtimne and return it to the JBossCache. E.g. if you run in JBossAS then this TransactionManagerLookup implementation (the one you configured, take a look at javadoc) will return the TransactionManager that the AS is using, from JNDI. Read the javadoc for GenericTransactionManagerLookup, should make things more clear. To return to the original question, the warning is caused by the fact that no TransactionManager is found within your runtime, and a default one will be used - which is not so clever, as per the name -> DummyTransactionManager. I'd say you can live with this one if you a) don't have to use it for distributed transactions and b) you don't see any performance degradations for transactions.
