I am facing an issue while indexing my entity through Hibernate Search API on IBM WebSphere 8.5.5.10. I am managing the transaction with spring Transaction. I have a created a RESTFUL web service call to index the entity.The Lucene index is working fine when running on local tomcat.

I am not sure what I am doing wrong.

Here is the Configuration file:-

<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="packagesToScan">
<list>
<value>edu.mayo.ctms.eve.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="hibernate.default_schema">eve_dev</prop>
<prop key="hibernate.generate_statistics">true</prop>


<prop key="hibernate.search.default.directory_provider">filesystem</prop>
<prop key="hibernate.search.default.indexBase">/apps/data/CTMS/eve/lucene/indexes</prop>

</props>
</property>

</bean>


<bean id="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
