Apache camel ServiceMix环境中的OpenJPA异常

ServiceMix、Camel、CXF 我写了一些使用JPA的数据库操作程序。这些并不复杂。它们工作正常，我写了一个过程，用它们中的一些。 process starter是一个基于文件的驼峰路线，一切都很完美。 好的，让初学者创建一个Web服务。没问题，我们使用ServiceMix，让我们使用CXF。这很简单，而且我们有一个集成的环境，可能会有什么问题。 WS-ready，调用过程并。。。我有一个例外：

<openjpa-2.3.0-r422266:1540826 nonfatal user error> 
org.apache.openjpa.persistence.ArgumentException: An error occurred while parsing the query filter 
"select i from IntegratedSystem i where i.code = :value". 
Error message: The name "IntegratedSystem" is not a recognized entity or identifier. 
Perhaps you meant IntegratedSystem, which is a close match. 
Known entity names: [Category, EsbLog, Message, MsgDispatcherCfg, 
ConsumerRequest, ProviderResponse, ServiceRegistry, ConsumerResponse, 
IntegratedSystem, ProviderRequest, CategoryItem]

这非常有趣，因为例外实体和紧密匹配是相同的。 问题是：

如果我从Camel路由调用一个过程，那么JPA工作正常；如果我从WS-implementation调用，那么JPA不知道该实体。你知道吗

WS和Camel路由是同一个项目和同一个包，如果我将JPA select替换为本机select，那么它可以正常工作。这不是一个好的解决方案，因为我使用了不止一个选项，并且我使用了JPA的潜力

谢谢大家!！ 费里

I had similar issue, and the cause was openjpa enhancer plugin within maven could not enhance the object as it could not find persistence.xml 
and required change as:

        <enforcePropertyRestrictions>true</enforcePropertyRestrictions>
        <persistenceXmlFile>${project.basedir}/src/main/resources/META-INF/persistence.xml</persistenceXmlFile>
        <classes>${project.build.outputDirectory}</classes>
        <workDir>${project.build.directory}\openjpa-work</workDir>
