不幸的是，我对jasperreports很新，我必须修改现有的项目。 版本4.0.1
有些不对劲，但我无法弄清楚究竟是什么。
如果我想生成pdf（通过浏览器点击），则会出现异常：
org.xml.sax.SAXParseException: Attribute "width" was already specified for element "reportElement".
日志说：
[11/20/13 9:56:52:784 CET] 00000028 SystemOut O Parse Fatal Error at line 91 column 118: Attribute "width" was already specified for element "reportElement".
我剥离了原始源（删除了所有子报告等），但错误仍然存在。我不知道，哪个文件引用了"line 91 column 118".
搞笑：随机我删除了reportElement中的forecolor和backcolor属性，它有效（暂时）。有没有已知的错误？
怎么办？
很抱歉。所以这里有更多信息：
我正在使用IBM WebSphere AST，jasperreport 4.0.1，iReport 4.0.1和oracleDB。
My.jrxml的编译在大多数情况下都不起作用。 myController的：
JasperReport jasperReport = JasperCompileManager
.compileReport(getServletContext()
.getRealPath(
Configuration.reportPath()
+ "My.jrxml"));
错误：
[11/20/13 13:30:29:535 CET] 0000002e SystemOut O Parse Fatal Error at line 91 column 118: Attribute "width" was already specified for element "reportElement".
org.xml.sax.SAXParseException: Attribute "width" was already specified for element "reportElement".

My.jrxml的第91行：
<reportElement key="staticText-4" x="0" y="167" width="535" height="45" forecolor="#000000" backcolor="#FFFFFF"/>
我希望这足够冗长...... 谢谢。
