I have a project which need to connect to oracle databases so i have the ojdbc jar file and a simple project.
我有一个需要连接到 oracle 数据库的项目，所以我有 ojdbc jar 文件和一个简单的项目。
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@"+this.host+":"+this.port+":"+this.db,this.user,this.pass);
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(query);
while (rset.next())
{
retStr += rset.getString(1) + ',';
}
stmt.close();
conn.close();
}
and I got an exception that the oracle.jdbc.driver.OracleDriveris not exists.

I did this step and I still get the exception. You will have to add the jar to your Classpath. You can do that in eclipse by right clicking on the Project --> Build Path --> Configure Build Path
我做了这一步，我仍然得到异常。您必须将 jar 添加到类路径中。您可以在 Eclipse 中通过右键单击项目 --> 构建路径 --> 配置构建路径来执行此操作

Under Libraries tab, click Add Jars and give the Jar (oracle jdbc driver).
在 Libraries 选项卡下，单击 Add Jars 并提供 Jar（oracle jdbc 驱动程序）。

In my Java projects, I create a /libdirectory at the same level as /srcand /bin. I throw any library jars in there and then right-click on the .jarfile and do "Build Path | Add to Build Path."
在我的 Java 项目中，我创建了一个/lib与/src和相同级别的目录/bin。我将所有库 jar 放入其中，然后右键单击该.jar文件并执行“构建路径 | 添加到构建路径”。

Ok. finally The solution is to add the jar file into the Web-Inf/lib directory because I have a Dynamic web application. Thank you all.
好的。最后解决方法是将jar文件添加到Web-Inf/lib目录中，因为我有一个动态的web应用程序。谢谢你们。

Directly the path is C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar
直接路径是C:\oraclex\app\oracle\product\10.2.0\server\jdbc\lib C:\oraclex\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar
