从数据库中获取旧值，即使在更新之后？

Question

I am using MySQL as DB, and Toplink essential as persistence layer.

There is a column, that I used to update regularly. But am always getting the value the value that was there at instance of START of the server.

But I restart the server, then only, its giving me the updated value.

What could be the problem?

Answer 1

I was able to fix the problem by updating Persistence.xml , which allowed to disable any kind of Caching done by toplink.

<properties>
    <property name="toplink.cache.shared.default" value="false"/>
</properties>
