Tomcat
异常如下：
org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Io 异常: The Network Adapter could not establish the connection)
at org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1225)
at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880)
Caused by: java.sql.SQLException: Io 异常: The Network Adapter could not establish the connection
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:180)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:222)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:335)
主要原因：
1.可能是server.xml文件的DataSource配置出错。
(1).如果用到的是本机上的数据，本地数据源里的部分配置为： username="pcisv62" password="11" url="jdbc:oracle:thin:@localhost:1521:orcl"
(2).如果用到的是服务器上的数据，则数据源里的部分配置为： username="pcisv62" password="11" url="jdbc:oracle:thin:@dbserver:1521:corev6"
（dbserver为服务器的名字，corev6为服务器上Oracle的SID）
2.可能是oracle的tnsnames.ora文件配置出错。
oracle的安装目录E:\oracle\ora92\network\admin下的tnsnames.ora：
本地配置：
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 主机名)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
)
)
或服务器配置：
COREV6_DBSERVER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1521))
)
(CONNECT_DATA =
(SID = COREV6)
(SERVER = DEDICATED)
)
)
