I am a new programmer and I want to write java program and use CityGML4j library for it. I saw some example of citygml4j programs but when I run them in netbeans I saw below error:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/xml/stream/writers/XMLWriter at org.citygml4j.builder.jaxb.xml.io.writer.JAXBOutputFactory.createCityGMLWriter(Unknown Source) at org.citygml4j.builder.jaxb.xml.io.writer.JAXBOutputFactory.createCityGMLWriter(Unknown Source) at buildingcreator.BuildingCreator.doMain(BuildingCreator.java:113) at buildingcreator.BuildingCreator.main(BuildingCreator.java:46) Caused by: java.lang.ClassNotFoundException: com.sun.xml.stream.writers.XMLWriter at java.net.URLClassLoader$1.run(URLClassLoader.java:372) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:360) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
