把下面的东西加到web.xml中
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/testDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
类的内部实现
try{
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:comp/env");
//获取连接池对象
Object obj = (Object) ctx.lookup("jdbc/testDB");
javax.sql.DataSource ds = (javax.sql.DataSource)obj;
Connection conn = ds.getConnection();
}
catch(Exception e)
{
System.out.print(e.toString());
}
