My applicationContextCache.xml

<bean id="CaseCache" class="com.aboveE.tpcPo.service.CacheService">
    <property name="caseDAO" ref="CaseDAO"/>
    <property name="offDocDAO" ref="OffDocDAO"/>
    <property name="caseQueryMap" ref="caseQueryCache" />
    <property name="officialQueryMap" ref="officialQueryCache" />
</bean>

My applicationContextDao.xml

<bean id="CaseDAO"
    class="com.aboveE.tpcPo.dao.CaseDAO">
    <property name="sessionFactory">

    </property>
</bean>

I'have already done a lot of research in google , but I can't resolve my problem...

please somebody can help me :(

Answer 1

The error message boils down to the following:

Error creating bean with name 'CaseDAO' defined in file:

The problem is with the CaseDAO bean.

Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError:

The problem is with the constructor.

Can you check whether the following is the case:

• Does com.aboveE.tpcPo.dao.CaseDAO have a no-args constructor?
• Is the constructor accessible (i.e. not private or protected, though Spring tries to make these constructors accessible)
• Could the constructor have thrown an exception?
• Is com.aboveE.tpcPo.dao.CaseDAO an abstract class?

Answer 2

it looks like you have an issue with your DAO. During its initialization(read, inside the constructor/initialization block, its own or its parent) there is an issue. Why don't you just debug it?
