我正在更新旧的应用程序，并尽可能少地重新编程。我创建了一个与旧页面类似的页面，其中仅包含一些测试数据，以确保我可以创建与 ejb/jpa 的链接，但我遇到了问题。我将发布 jsp、persistence.xml 和错误。在研究了网络之后，我仍然不明白问题是什么或如何解决它。谢谢。

jsp

<%@ page import="com.ray.adt.model.Gridmaster" %>
<jsp:useBean id="GridMasterBean" scope="page" class="com.ray.adt.ejb.grid.GridMasterBean"/>
<%
System.out.println ("Start")    ;
String gridid = request.getParameter("gridid");
System.out.println ("String id is " + gridid);
Gridmaster master = null;
Integer gridInteger = Integer.parseInt(gridid);
master = GridMasterBean.findGrid(gridInteger);
String title = "None";
title =  master.getProgram();
System.out.println ("title is " + title);
%>

最佳答案

您必须将以下行添加到您的 persistence.xml

如果您使用Glassfish:

<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform" />

如果您使用JBoss:

<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform" />

这应该可以解决您的问题。
