我收到ClassNotFoundException Apache-FOP我已将fop.jar包含在websphere 7.0的WEB-INF lib目录中。我将xmlgraphics-commons-1.4.jar添加到我的lib中，然后抛出验证错误。

Answer 1

请记住，jar文件主要只是一个带有清单的zip文件：使用您最喜欢的解压缩工具解压缩jar，查看 META-INF / MANIFEST.MF 文件，并检查类路径上的所有内容都存在。对我来说（FOP 1.0），类路径条目就是这个：

Class-Path：avalon-framework-4.2.0.jar batik-all-1.7.jar commons-io-1。 3.1.jar commons-logging-1.0.4.jar fop-hyph.jar serializer-2.7.0.jar s ervlet-2.2.jar xalan-2.7.0.jar xercesImpl-2.7.1.jar xml-apis-1.3.04.j ar xml-apis-ext-1.3.04.jar xmlgraphics-commons-1.4.jar

Answer 2

...... 5年后......

我遇到了同样的问题并通过搜索包名称迭代所有抛出的NoClassDefFoundError来快速修复它，例如org.apache.xmlgraphics，并添加了从Maven Repository下载的所有遗失.jars。

也许，您可以使用Maven插件来避免依赖地狱并引用所有丢失的.jars但我没有尝试过。

我从2017年4月开始使用 Apache FOP 2.2版。将以下.jars添加到WEB-INF/lib，您可以处理：

的Avalon框架-4.2.0.jar
蜡染桥-1.9.1.jar
公地-IO-2.4.jar
共享记录-1.2.jar
fop.jar
org.apache.batik.css-1.6.0.v201011041432.jar
org.apache.batik.svggen-1.6.0.v201011041432.jar
org.apache.batik.transcoder-1.6.0.v201011041432.jar
org.apache.batik.util-1.6.0.v201011041432.jar
xmlgraphics-公地2.2.jar

我应该在apache fop的类路径中包含哪些jar
