Hi, I am currently facing the following problem: I need to configure my ear for multiple environments. Therefor I used the hibernate.properties in the root folder of the ear to configure my persistence-layer. This works perfectly so far, because Hibernate finds the properties through it´s Environment and loads them. BUT: if I now deploy another ear, holding a hibernate.properties for configuring the second application, the hibernate.properties are simply ignored and - even more - the hibernate.properties from the first deployment are used for my second deployment as well. While looking in the Hibernate source code I saw that the corresponding variable is defined as a static variable. private static final Properties GLOBAL_PROPERTIES; It seems as if this class will be loaded only once and the first deployment wins. I already tried to work with isolated classloaders and set the value for | <attribute name="Isolated">true</attribute> | in the ear-deployer.xml to false. But this didn´t make any difference. Does anyone has an idea how to use multiple hibernate.properties or any other way to handle multiple configurations for the persistence-layer?
