java.lang.NoSuchMethodError : org. apache.fop.apps.FopFactory.newInstance(Ljava/io/File;)Lorg/apache/fop/apps/FopFactory;

Question

我使用了 apache FOP 2.0 jar 和下面的代码

  FopFactory fopFactory = FopFactory.newInstance(new File("."));

并出现以下错误那么原因和解决方案是什么？
我还使用过 xmlgraphics-commons 1.5

但是没用

Answer 1

尝试这样做:

FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
