我正在Adobe Flex中开发一个小应用程序，它连接到一个tomcat servlet，用于从Oracle DB获取数据。 Flex App连接到Servlet（localhost-＆gt; localhost），但servlet无法访问Oracle DB（localhost-＆gt; LAN中的另一台机器）。 我尝试使用Oracle SQLDeveloper（用Java开发），它工作正常。
它在Windows PC（Eclipse中的tomcat）上工作正常，但是当我使用我的Mac（也是Eclipse中的tomcat）时，servlet给了我错误...
这是我的context.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/Anagrafica">
<Resource name="jdbc/SimplyAnagraficaDS"
auth="Container"
type="javax.sql.DataSource"
url="jdbc:oracle:thin:@IP:PORT:SID"
username="test"
password="test"
driverClassName="oracle.jdbc.OracleDriver"
maxActive="8" />
</Context>
这是采取连接的方法：
public static Connection getConnection() throws NamingException, SQLException {
Context ic = new InitialContext();
DataSource dataSource = (DataSource) ic
.lookup("java:comp/env/jdbc/SimplyAnagraficaDS");
return dataSource.getConnection();
}
这是StackTrace（返回dataSource.getConnection（）;）

我没有防火墙。所以......我真的无法理解发生了什么。 （我尝试了一切。更改配置，更改tomcat bin ...）
在tomcat \ lib中有ojdbc7.jar用于连接到DB。
我正在使用jdk 1.7 u75和Tomcat 7与Oracle 10g。
在Windows机器上，我也使用jdk 1.7u75和Tomcat 7。
