DocBook和webhelp

Question

下面是这里提到的步骤：http://docbook.sourceforge.net/release/xsl/current/webhelp/docs/ch02s01.html

ant webhelp -Doutput-dir=test-ouput (我认为ouput是文档中的一个错误，但我用test-ouput和test-output进行了测试，结果相同)

测试用

• Windows 8和Windows 8.1
• java版本"1.7.0_51“
• 蚂蚁1.8.2和蚂蚁1.9.3
• docbook-xsl-1.78.1
• 干红-2_11_
• 撒克逊6-5-5

知道我该往哪儿看吗？

Answer 1

根据堆栈跟踪，您似乎正在使用Xalan进行xsl转换。建议在Webhelp中使用Saxon6.5.5，这也是Java的一个推动力。您可以通过将build.properties中的xslt类路径设置到Saxon的位置来指向saxon。同时，还应该设置xercesImpl.jar和XMLapis.jar属性。

修改webhelp build.properties中的以下内容，使它们指向指示的jars的本地副本：

• 萨克森6.5罐
• Xerces 2: xercesImpl.jar
• ：xml-apis.jar xslt-processor-classpath=/usr/share/java/saxon-6.5.5.jar xercesImpl.jar=/usr/share/java/xercesImpl.jar xml-apis.jar=/usr/share/java/xml-apis.jar

Answer 2

非常重要的

build.properties

xslt-processor-classpath=d:\\apps\\saxon\\saxon.jar
xercesImpl.jar=d:\\apps\\xerces\\xercesImpl.jar;d:\\apps\\saxon\\saxon.jar
xml-apis.jar=d:\\apps\\xerces\\xml-apis.jar

启动xercesImpl...的行还需要对saxon.jar进行额外的引用，以处理更大的saxon.jar输入文件。
