Hi,
Question 1:
========
I define transactions as follows :
Code:
...
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="target.service.research" class="com.mycompany.research.ResearchServiceImpl" lazy-init="true"/>
<bean name="service.research" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="txManager"/>
<property name="target" ref="target.service.research"/>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<bean id="target.service.admin" class="com.mycompany.admin.AdminServiceImpl" lazy-init="true"/>
<bean name="service.admin" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="txManager"/>
<property name="target" ref="target.service.admin"/>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
...
When I run my application it throws the following exception:
Code:
ERROR (JTATransaction.java:61) - Could not find UserTransaction in JNDI

I believe it thinks that I'm running my application within application server, in fact I'm not.
But when I change the definition as follows :
Code:
...
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="target.service.research" class="com.mycompany.research.ResearchServiceImpl" lazy-init="true"/>
<bean name="service.research" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="txManager"/>
<property name="target" ref="target.service.research"/>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<bean id="service.admin" class="com.mycompany.admin.AdminServiceImpl" lazy-init="true"/>
...
my application runs without problem, as you can see from above definition it only works if I define transaction only for one service, no more.
What's the problem ?
Question 2:
=========
Actually class 'com.mycompany.admin.AdminServiceImpl' and class 'com.mycompany.admin.ResearchServiceImpl' derive from the same abstract class, i.e com.mycompany.base.AbstractServiceImpl in which all 'save*' and 'delete*' methods are defined.
Since 'com.mycompany.base.AbstractServiceImpl' is an abstract class is it possible to define transaction on this class once instead of in those two descendant classes ? So that I don't have to repeatedly define transactions everytime I create classes that derive from 'com.mycompany.base.AbstractServiceImpl' and the methods (save* and delete*) are located in their parent class anyway.
Thanks in advanced.
