我已经在classpath中添加了ojdbc.jar文件，并验证了用户名和密码。请帮忙。

提前致谢。

Answer 1

在iReport的类路径中添加classes.12.jar文件后检查这个，或者你可以直接复制到

C:\Program Files\Jaspersoft\iReport-5.2.0\ireport\libs 

1： - 要添加新数据库，请单击数据库图标 - ＆gt; JDBC连接 - ＆gt;下。

2： - 选择JDBC驱动程序类Oracle： -          （oracle.jdbc.driver.OracleDriver）

3： - URL       语法：jdbc：oracle：thin：@localhost：1521：DatabaseName     示例1：jdbc：oracle：thin：@localhost：1521：orcl                                         （其中orcl是Oracle的SID）     例2：jdbc：oracle：thin：@ 192.168.2.9：1521：orcl                                          （使用IP的远程数据库连接）

4）用户名＆amp;密码

5）单击“测试连接”。

Answer 2

我遇到了同样的问题，我按照以下步骤操作：

1. 将 ojdbc6.jar 复制到ireports / libs。
2. 转到工具> 选项 在“ 类路径”标签下，您需要添加已添加libs文件夹的新ojdbc jar。
3. 重新启动 jaspersoft ireports designer 软件。

现在，当您尝试添加新数据库时，oracle选项是 black 而不是 red ，这意味着它已启用。
