SQLException：没有为jdbc找到合适的驱动程序：oracle：thin：@ // localhost：1521 / orcl
我正在尝试开发一个从eb服务类连接到Oracle数据库的Java EE应用程序，但我遇到了一个
SQLException: No suitable driver found for jdbc:oracle:thin:@//localhost:1521/orcl
我在类路径中有ojdbc6.jar ，我也在JBoss部署文件夹中validation了这一点。
我的应用程序EAR由WAR组成。 这有什么问题（根本原因）？ 请帮忙。
persistence.xml中的连接URL：
> "jdbc:oracle:thin:@//localhost:1521/orcl"

Oracle数据库版本：11.2.0。
驱动程序版本是否需要与数据库版本匹配？
编辑：
-
如何跟踪程序加载驱动程序的文件路径？ 这增强了我找到根本原因。 谢谢。
-
如何启用ojdbc6-g日志记录？ 我试过跟这个Oracle_JDBC，但我不知道如何完成它。 如何全局设置java系统属性？ 我知道环境变量可能不是一个好的选择。 还有其他想法吗？ 我只想在使用这个java时将-Doracle.jdbc.Trace = true和-Djava.util.logging.config.file添加到jvm创建。 是否在启动期间设置了oracle数据库？
-
如何启用hibernate日志记录？
-
我正在使用Hibernate-4.1.1和JBoss 7.1。
请帮忙。
谢谢。
“ojdbc.jar”不在应用程序服务器的CLASSPATH中。
只需告诉我们它是哪个应用程序服务器，我们就会告诉您应该在哪里放置驱动程序。
编辑 ：我看到标签jboss所以它必须放在文件夹"$JBOSS_HOME/server/default/lib/"
“没有合适的驱动程序”通常意味着您提供给连接的JDBC URL具有不正确的语法或者根本没有加载驱动程序。
当调用方法getConnection时， DriverManager将尝试从初始化时加载的驱动程序中找到合适的驱动程序，并使用与当前applet或应用程序相同的类加载器显式加载的驱动程序。（使用Class.forName() ）
例如
import oracle.jdbc.driver.OracleDriver; Class.forName("oracle.jdbc.driver.OracleDriver");
还要检查类路径中是否有ojdbc6.jar 。 我建议将物理位置的.jar放到项目的JBoss "$JBOSS_HOME/server/default/lib/"目录中。

你最近提到过hibernate 。
检查您的hibernate.cfg.xml文件是否具有如下所示的连接属性：
oracle.jdbc.driver.OracleDriver jdbc:oracle:thin:@localhost:1521:orcl scott tiger
有时这是简单的事情。 在我的情况下，我有一个无效的url。 我在at符号（@）之前遗漏了一个冒号。 我有“jdbc：oracle：thin @ // localhost”而不是“jdbc：oracle：thin：@ // localhost”希望这可以帮助其他人解决这个问题。
对我来说，我确实输入了一个无效的URL： orcl而不是jdbc:oracle:thin:@//localhost:1521/orcl
这样做
set classpath=%classpath%(ur jarfile);
首先，如果您在服务器（JBoss）中使用Java EE 6开发应用程序，则最好使用DataSource 。 然后，您可以从此DataSource获取Connection。 最好使用连接池。
然后，从JBoss AS 7开始，必须将JDBC驱动程序声明为模块。 这在这里描述。
使用OJDBC 6（11.x），驱动程序的名称应为“oracle.jdbc.OracleDriver”。 这是在SPI模式下注册的名称（请参阅此文件的内容： META-INF / services / java.sql.Driver ）。
从Java 6和JDBC 4.0开始，JDBC驱动程序将自动注册 。
最后，您必须在JBoss： DataSource配置中声明一个DataSource。

下载JDBC驱动程序并添加到库中。 下载链接http://www.oracle.com/technetwork/apps-tech/jdbc-112010-090769.html
我有同样的问题。 要在Jboss 7 AS中修复它，我将oracle驱动程序jar文件复制到Jboss模块文件夹。 示例： ../jboss-as-7.1.1.Final/modules/org/hibernate/main 。
您还需要更改“module.xml”
