Question

我创建了一个使用DB的BIRT报告模板（在我的例子中是Oracle DB）。查询如下：

从某些东西中选择某些东西，数量是多少？

从Eclipse（对于BIRT报告）一切正常。问题是我想创建一个能完成这项工作的Web服务。所以我尝试传递连接，如：

Connection conn = null;
    try {
        DriverManager.registerDriver((Driver) Class.forName("oracle.jdbc.OracleDriver").newInstance());
        conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:name","user","pass");
    } catch (SQLException | InstantiationException | IllegalAccessException | ClassNotFoundException ex) {
        // handle any errors
        System.out.println("SQLException Message: " + ex.getMessage());
    }

    task.getAppContext().put("OdaJDBCDriverPassInConnection", conn);
    task.getAppContext().put("OdaJDBCDriverPassInConnectionCloseAfterUse", false);

我得到了：

我在网上发现的只有：https://bugs.eclipse.org/bugs/show_bug.cgi?id=360702但它并没有真正帮助我，我不确定我理解这些评论。

有人可以帮助我吗？代码示例很不错。

确定，

实际上这个代码似乎没有问题。我刚刚使用了BIRT（4.2.0）的一些错误版本。更新到4.4.1后一切正常。

将Oracle连接传递给BIRT报告
