java web jdbc oci 方式连接oracle报错UnsatisfiedLinkError

环境为AIX Version 5.3!
sqlplus sqlldr 可用，
java web jdbc oci 方式连接数据库不成功
Connection conn = null;

Statement stmt = null;

ResultSet rs = null;

try {

Class.forName("oracle.jdbc.OracleDriver");

conn = DriverManager.getConnection("jdbc:oracle:oci:@bbs", "user", "password");

stmt = conn.createStatement();

rs = stmt.executeQuery("select name from abc");

while (rs.next()) {  
    String s = rs.getString(1);  
    System.out.println(s);  
}  

} catch (Exception e) {

e.printStackTrace();

}

System.out.println(System.getProperties().get("java.library.path"));输出：/oracle11/app/oracle/11.2.0/lib

windows上测试成功：
-Djava.library.path=E:\oracle\product\10.2.0\client_1\BIN

配置一下环境变量:
Add [ORACLE_HOME]/jdbc/lib/ojdbc5.jar to your CLASSPATH if you use JDK 1.5 or [ORACLE_HOME]/jdbc/lib/ojdbc6.jar if you use JDK 1.6

• Add [ORACLE_HOME]/jlib/orai18n.jar to your CLASSPATH if needed.

• Add [ORACLE_HOME]/jdbc/lib to your LIBPATH and LD_LIBRARY_PATH if you use the JDBC OCI driver.
