FopFactory.newInstance（）时出现Fop异常

FopFactory.newInstance（）时出现Fop异常

我解决了我的问题！我有xmlgraphics-commons-1.3而不是xmlgraphics-commons-1.5。这很奇怪，因为我使用了fop
bin附带的所有库。

顺便说一下，转换并在浏览器中显示pdf文件的代码如下：

<action name="printDomAction"   method="xmlToPdf">        <result type="stream" name="success"> <param name="contentType">application/pdf</param> <param name="contentDisposition">filename="ResultXML2PDF.pdf"</param> <param name="bufferSize">1024</param>        </result>        <interceptor-ref name="defaultStack"/>    </action>

和方法

private InputStream inputStream;public String xmlToPdf() {     try {         System.out.println("FOP ExampleXML2PDFn");         System.out.println("Preparing...");         // Setup directories         File baseDir = new File("C:\Users\Administrator\workspace\path\actions\forms\");         File outDir = new File(baseDir, "out");         outDir.mkdirs();         // Setup input and output files         File xmlfile = new File(baseDir, "testeFOPxml.xml");         File xsltfile = new File(baseDir, "xml2fo.xsl");         File pdffile = new File(outDir, "ResultXML2PDF.pdf");         System.out.println("Input: XML (" + xmlfile + ")");         System.out.println("Stylesheet: " + xsltfile);         System.out.println("Output: PDF (" + pdffile + ")");         System.out.println();         System.out.println("Transforming...");         // configure fopFactory as desired         final FopFactory fopFactory = FopFactory.newInstance();         FOUserAgent foUserAgent = fopFactory.newFOUserAgent();         // configure foUserAgent as desired         ByteArrayOutputStream out = new ByteArrayOutputStream();         TransformerFactory tFactory = TransformerFactory.newInstance();         Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF,foUserAgent, out);         //Setup input         Source src = new StreamSource(xmlfile);         //Setup Transformer         Source xsltSrc = new StreamSource(xsltfile);         Transformer transformer = tFactory.newTransformer(xsltSrc);         //Make sure the XSL transformation's result is piped through to FOP         Result res = new SAXResult(fop.getDefaultHandler());         transformer.transform(src, res);         System.out.println("Success!");         ByteArrayOutputStream baos = out;         inputStream = new ByteArrayInputStream(baos.toByteArray());     } catch (Exception e) {     e.printStackTrace(System.err);         System.exit(-1);     } return SUCCESS; }
