我有一个与 EnglishNumberToWords.jar 一起使用的表达式的报告。这个 .jar 将数字转换为单词并在 iReport 中完美运行，但当我将其作为 Web 应用程序执行时会出错。没有这个报告我做错了什么？此文本字段表达式的代码：
<textFieldExpression><![CDATA[EnglishNumberToWords.convert( $F{ODEMELER_MEBLEG}.intValue() )+" manat "+$F{QEPIQ}+" qpiq"]]></textFieldExpression>
这是错误：
Error occured while displaying report net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : Source text : EnglishNumberToWords.convert( $F{ODEMELER_MEBLEG}.intValue() )+" manat "+$F{QEPIQ}+" qpiq"
