我正在尝试使用fop 2.1将xml文件嵌入到PDF / A3-b文件中并得到以下答案：

这是我的.fo文件

<?xml version="1.0" encoding="UTF-8"?> 
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" 
         font-family="PT-Sans" font-weight="normal" font-style="normal"

            </fo:block-container>
        </fo:flow> 
    </fo:page-sequence> 
</fo:root>

fop.xconf文件的扩展方式与fop的website中描述的一样。

最后来自我的bash shell的执行命令

java -jar build/fop.jar -c conf/fop.xconf -fo examples/fofile.fo -pdf examples/pdffile.pdf

使用-c执行但没有块工作正常不使用-c执行但使用块也可以正常工作。

java -jar build/fop.jar -c conf/fop.xconf

是＆＃34;的命令，正好使用此fop.xconv文件＆＃34;。

我错过了什么吗？

Answer 1

我尝试通过修补fop 2.1源码（fop-2.1 / src / java）来解决它：

*** org/apache/fop/pdf/PDFProfile.java.mod  2016-07-13 16:08:19.621331387 +0200
--- org/apache/fop/pdf/PDFProfile.java  2016-01-07 15:13:29.000000000 +0100
*************** public class PDFProfile {
*** 332,338 ****
      /** Checks if embedded files are allowed. */
      public void verifyEmbeddedFilesAllowed() {
          final String err = "{0} does not allow embedded files.";
!         if (getPDFAMode() != PDFAMode.DISABLED && getPDFAMode() != PDFAMode.PDFA_3A && getPDFAMode() != PDFAMode.PDFA_3B && getPDFAMode() != PDFAMode.PDFA_3U ) {
              throw new PDFConformanceException(format(err, getPDFAMode()));
          }
          if (isPDFXActive()) {
--- 332,338 ----
      /** Checks if embedded files are allowed. */
      public void verifyEmbeddedFilesAllowed() {
          final String err = "{0} does not allow embedded files.";
!         if (isPDFAActive()) {
              throw new PDFConformanceException(format(err, getPDFAMode()));
          }
          if (isPDFXActive()) {

然后编译

javac -cp ../../build/fop.jar org/apache/fop/pdf/PDFProfile.java

备份原始jar

cp ../../build/fop.jar ../../build/fop.jar.orig

并将新类添加到jar

jar -uf ../../build/fop.jar org/apache/fop/pdf/PDFProfile.class

虽然很脏，但我还添加了问题FOP-2625

修改

问题由Simon Steiner在fop trunk版本中修复。

FOP PDF / A-3b不允许嵌入文件
