Java 使用POI设置HSSFCellUtil的CellStyleProperty时出现问题

我有一个Java类，它使用ApachePOI在Excel中生成报告

当我从IDE或命令提示符运行Java类时，我只看到来自LOG4J的警告消息，如下所示：

log4j:WARN No appenders could be found for logger (org.apache.commons.beanutils.converters.BooleanConverter).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

尽管有警告消息，报告还是成功生成

但是当我从使用JSP的web应用程序运行它并将表单提交给调用Java类的Servlet时，Java类似乎在设置单元格的样式属性时遇到了问题。下面是Java代码和堆栈跟踪

我正在一个独立的OC4J上测试它，我使用的IDE是Oracle的JDeveloper。JavaJDK是1.4.2

我昨天一整天都在东张西望，但似乎找不出原因

代码：
