Hello... I was working withouth any problems on WSAD 5.1 with Hibernate 2.1bx versions. However I lastly upgraded to 2.1.1 and decided to use a JVM level cache as well. (I've chosen ecache for that purpose).. However I cannot make it work. Here is what I've done:

----------------------------------------------------------------
I've placed the ecache.xml file to my classpath:
<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
<cache name="iyte.oi.components.birimler.fakulte.model.FakulteDO"
maxElementInMemory="50"
eternal="true"/>
<cache name="iyte.oi.components.birimler.bolum.model.BolumDO"
maxElementInMemory="80"
eternal="true"/>
<cache name="iyte.oi.components.birimler.program.model.ProgramDO"
maxElementsInMemory="80"
eternal="true"/>
......
</ehcache>
-------------------------------------------------------------------

I've updated my hibernate-config.xml file as below...

<hibernate-configuration>
<!-- a SessionFactory instance listed as /jndi/name -->
<session-factory>
<!-- properties -->
<property name="connection.datasource">jdbc/OGRENCI</property>
<property name="dialect">net.sf.hibernate.dialect.DB2Dialect</property>
<property name="show_sql">true</property>
<property name="use_outer_join">true</property>
<property name="hibernate.default_schema">OILISANS</property>
<property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.Provider</property>
<property name="hibernate.transaction.manager_lookup_class">net.sf.hibernate.transaction.WebSphereTransactionManagerLookup</property>
<!-- mapping files -->
<mapping resource="Birimler.hbm.xml"/>
.....

--------------------------------------------------------------------------

I've changed my mapping definitions as shown below(added <cache usage> elements):

<class name="iyte.oi.components.birimler.fakulte.model.FakulteDO" table="FAKULTELER">
<cache usage="read-write"/>
<id name="id" column="ID" type="short">
<generator class="identity"/>
</id>
<property name="fakulteAd" column="FAKULTE_AD" type="string"/>
<property name="fakulteKod" column="FAKULTE_KOD" type="string"/>
<property name="ingFakulteAd" column="ING_FAKULTE_AD" type="string"/>
<set name="bolumler" inverse="true" lazy="true">
<key column="FAKULTE_ID"/>
<one-to-many class="iyte.oi.components.birimler.bolum.model.BolumDO"/>
</set>
</class>

--------------------------------------------------------------------------
I've added the following files that come with 2.1.1 distribution to my classpath:
cglib2, commons-collections, commons-lang, dom4j, ehcache, hibernate2, jta, log4j, odmg, xerces, xml-apis...

However, while initializing session factory I get the following error:

Can anyone please help me on this?

Try using the latest ehcache version (0.7) and be sure to have no old jars on your classpath.
