问题是这样，系统中要对oracle数据库的clob字段进行插入， 使用如下方法：

    StringReader c = new StringReader(s);
    pstmt.setCharacterStream(i+1, c);

居然报错!错误如下：

    Cause: java.lang.AbstractMethodError:
    oracle.jdbc.driver.T4CPreparedStatement.
    setCharacterStream(ILjava/io/Reader;)V

然后就是各种google、换驱动，最后在

找到了答案；

最后修改为如下代码后，程序正确执行：

    StringReader c = new StringReader(s);
    pstmt.setCharacterStream(i+1, c,s.length());

 oracle这重载方法真........
