org.apache.openjpa.persistence.ArgumentException：發生錯誤而解析查詢過濾器

I am getting this Exception in Open JPA. 

<openjpa-1.2.3-SNAPSHOT-r422266:1295280 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: An error occurred while parsing the query filter "select a from Test a where a.something='D10584707'".

這裏是我的堅持XMLorg.apache.openjpa.persistence.ArgumentException：發生錯誤而解析查詢過濾器

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
     http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"

     <jta-data-source>jdbc/MyDatasource</jta-data-source> 
     <class>com.vo.Test</class>  
    </persistence-unit>

我有我的扭曲作爲Web應用程序歸檔應用程序，它工作正常。但是，如果我將EJB3的相同應用程序作爲我遇到問題的地方。

我正在上爲7.0

我得到了我的問題的解決方案

我失蹤RuntimeUnenhancedClasses屬性在我的persistence.xml

現在我的堅持XML看起來像這樣

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" 
version="1.0"> 
<persistence-unit name="MyDataSource"> 
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> 
    <jta-data-source>jdbc/MyDatasource</jta-data-source> 
    <class>com.vo.Test</class>  
    <properties> 
    <property name="RuntimeUnenhancedClasses" value="supported"/> 
    <property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE" /> 
    </properties> 
</persistence-unit>

請，請，請不要設置openjpa.RuntimeUnenhancedClasses來支持。這是一個半實施的功能，會導致你的問題。你的根本問題是你沒有增強你的實體。這就是說，因爲你正在WebSphere中運行，容器鉤子應該會增強你爲你的實體。 – Rick 2012-07-25 15:26:34

我有同樣的問題，通過更正jpql來解決問題。

是：SELECT c FROM NIMBUSOrganizationUnitEntityObject c WHERE **uuid** = :uuid

到：SELECT c FROM NIMBUSOrganizationUnitEntityObject c WHERE ***c.uuid*** = :uuid
