我在 Apache-FOP 中遇到 ClassNotFoundException 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 添加到我的库中，然后它抛出验证错误。
由:java.lang.VerifyError: JVMVRFY012堆栈形状不一致引起；类=org/apache/fop/fo/ElementMappingRegistry，方法=findFOMaker(Ljava/lang/String;Ljava/lang/String;Lorg/xml/sax/Locator;)Lorg/apache/fop/fo/ElementMapping$Maker;, pc=127

最佳答案
请记住，jar 文件主要只是一个带有 list 的 zip 文件:使用您最喜欢的解压缩工具解压 jar，查看 META-INF/MANIFEST.MF 文件，然后检查类路径上的所有内容都存在。对于我(FOP 1.0)来说，类路径条目是这样的:
类路径: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 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
关于java - 我应该在 apache fop 的类路径中包含哪些 jar，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13690735/
