無法加載類 - JDBC

我試圖得到一個JavaEE的項目爲Glassfish 4.0上運行，但是當我嘗試刷新插件（堅持）到SQL Server數據庫，它拋出這個錯誤：無法加載類 - JDBC

org.omg.CORBA.MARSHAL: WARNING: 00810057: Could not load class com.microsoft.sqlserver.jdbc.SQLServerException vmcid: OMG minor code: 57 completed: Maybe

該連接在Netbeans中運行，用於運行命令和生成實體類。

Bean方法：

public int addUser(UserDetails u) { 
    try{ 
     User uP = new User(u.getUserName(), u.isEnabled(), u.isAdmin()); 
     em.persist(uP); 
     return 0; 
    } 
    catch(Exception e) 
    { 
     throw new EJBException(e); 
    } 
}

的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> 
    <persistence-unit name="LibraryBeanPU" transaction-type="JTA"> 
    <jta-data-source>JavaEE_Library</jta-data-source> 
    <exclude-unlisted-classes>false</exclude-unlisted-classes> 
    <properties/> 
    </persistence-unit> 
</persistence>

客戶：

public static void main(String[] args) { 
    LibraryClient lc = new LibraryClient(); 
} 

public LibraryClient() 
{ 
    LibraryFacadeRemote request = (LibraryFacadeRemote) getEJBBean("LibraryFacade"); 
    request.addUser(new UserDetails("admin", true, true)); 
} 

public Object getEJBBean(String beanName) { 
    try { 
     InitialContext ctx = new InitialContext(); 
     return ctx.lookup(beanName); 
    } catch (Exception ex) { 
     System.err.println("ERROR: while locating bean from the server " + ex.getMessage()); 
     return null;  
    } 
}
