求救了！不知道怎么回事？我是在进行String转Clob字段是，创建一个Clob对象时报的错，源码如下：public static Object createOracleLob(Connection conn, String lobClassName) throws Exception { 
Class lobClass = conn.getClass().getClassLoader().loadClass(lobClassName);      boolean boo=false;
final Integer DURATION_SESSION = new Integer(lobClass.getField("DURATION_SESSION").getInt(null)); 
final Integer MODE_READWRITE = new Integer(lobClass.getField("MODE_READWRITE").getInt(null)); 
Method createTemporary = lobClass.getMethod("createTemporary",new Class[] { Connection.class, boolean.class, int.class }); 
Object lob = createTemporary.invoke(null, new Object[] { conn,  new Boolean(boo),DURATION_SESSION });      //这一句报错
Method open = lobClass.getMethod("open", new Class[] { int.class }); 
open.invoke(lob, new Object[] { MODE_READWRITE }); 
return lob; 
}

Answer 1

Object lob = createTemporary.invoke(null, new Object[] { conn,  new Boolean(boo),DURATION_SESSION }); 你肯定？

Answer 2

传null也能用啊。。
下面这样试试看？Object lob = createTemporary.invoke(lobClass.newInstance(), new Object[] { conn,  new Boolean(boo),DURATION_SESSION });

Answer 3

改完了之后又报下面这个错java.lang.IllegalAccessException: Class com.omgap.selfmonthreport.MonReptPubAndInqSave can not access a member of class oracle.sql.CLOB with modifiers "protected"
