问题描述

将项目jar文件导出到文件服务器后，jpa的Entitymanager的创建将不再起作用.

After exporting the project jar file to the fileserver the creation of the entitymanager of jpa does not work anymore.

有以下详细信息:

我使用Glassfishv3项目中的EclipseLink
我从网站上下载了EclipseLink 2.4....
org.eclipse.persistence.core.jar，org.eclipse.persistence.jpa.jar，javax.persistence.jar和eclipselink.jar位于lib文件夹中.
persistence.xml位于src内的META-INF文件夹中. (我使用日食日光灯)
这是persistence.xml的内容

I use EclipseLink from Glassfishv3 Project
I downloaded EclipseLink 2.4... from the website.
org.eclipse.persistence.core.jar, org.eclipse.persistence.jpa.jar, javax.persistence.jar and eclipselink.jar are in the lib folder.
persistence.xml is in META-INF folder inside src. (I use eclipse helios)
this is the content of the persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<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_2_0.xsd"
    version="2.0"
    xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="QIS" transaction-type="RESOURCE_LOCAL" >
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <class>com.quoka.qis.lib.persistence.Type</class>
    </persistence-unit>
</persistence>

整个事情都在eclipse中起作用，但不能在文件服务器中起作用. :-)

The whole thing works inside eclipse but not from the fileserver. :-)

错误消息是:

org.eclipse.persistence.internal.jpa.deployment.xml.parser.XMLException
    URI was not reported to parser for entity [document])

(24) java.lang.Thread.run(Thread.java:662)

DBConnection是:

DBConnection is:

Map<String, String> properties = new HashMap<String, String>();
properties.put("javax.persistence.jdbc.driver", "com.sybase.jdbc3.jdbc.SybDriver");
properties.put("eclipselink.target-database", "Sybase");
properties.put("javax.persistence.jdbc.url", "jdbc:sybase:Tds:"+meta.getServerName()+":"+meta.getPort());
properties.put("javax.persistence.jdbc.user", meta.getUserName());
properties.put("javax.persistence.jdbc.password", meta.getPassword());
properties.put("eclipselink.logging.level", "INFO");

EntityManagerFactory emf = Persistence.createEntityManagerFactory("QIS", properties);
em = emf.createEntityManager();
