jdbc:oracle:oci8:ORCLDB的问题

我的classpath：
  -classpath $PWD/bin:$ORACLE_HOME/rdbms/jlib/xdb6.jar:$ORACLE_HOME/lib/xmlparserv2.jar:$ORACLE_HOME/jdbc/lib/ojdbc6.jar:$ORACLE_HOME/ucp/lib/ucp.jar:$PWD/lib/xml.jar:$ORACLE_HOME/rdbms/jlib/xdb.jar 
路径都没问题，但是在执行的时候有异常。Exception in thread "main" java.lang.UnsatisfiedLinkError: oracle.jdbc.driver.T2CConnection.t2cLogoff(J)I

这大概是哪的问题呢？我怀疑是ojdbc6.jar的问题。但是仍旧没有解决。
