我想使用fop-1.1显示PDF文件。 jar和基于JRE 1.6的xmlgraphics-commons-1.5.jar。但我有如下例外：使用Fop库的NoSuchMethodError
EXCEPTION]

和java类：
HttpServletResponse response = request.getServletResponse(true);
String strXSLPath = Property.strXSLPath;
IJCOClientService clientService = (IJCOClientService) request
.getService(IJCOClientService.KEY);
poolEntry = clientService.getJCOClientPoolEntry("SAP_R3_PAYSTUB",
request);
this.tFactory = TransformerFactory.newInstance();
this.fopFactory = FopFactory.newInstance();
ByteArrayOutputStream out = new ByteArrayOutputStream();
FOUserAgent userAgent = fopFactory.newFOUserAgent();
userAgent.getRendererOptions().put(
"encryption-params",
new PDFEncryptionParams(null, "password", true, false,
false, false));
Fop fop = fopFactory.newFop(org.apache.xmlgraphics.util.MimeConstants.MIME_PDF, userAgent, out);
Source xsltSrc = null;
xsltSrc = new StreamSource(strXSLPath
+ "demo.xsl");
Transformer transformer = this.tFactory.newTransformer(xsltSrc);
Source src = new StreamSource(createXML(poolEntry, request));
transformer.transform(src, res);
response.setContentType("application/pdf");
response.setContentLength(out.size());
response.getOutputStream().write(out.toByteArray());
response.getOutputStream().flush();
线150是指在日志
transformer.transform(src, res);

在互联网上进行研究，我特别添加了fop-1.1.j ar基于link
但问题仍然存在。请建议我。
它看起来像一个版本不匹配，所以只需添加FOP 1.1可能是不够的 - 你可能有FOP的较新或旧版本需要被去除。但我只是猜测，您提供的信息不够，无法了解您的问题。 – Gimby
@Gimby：包含classpath文件。请帮我看看 –
