does know why getting error?

here few pictures:

thanks hrach

edit:

i not immediate errors, when run code below, these errors:

exception in thread "main" java.lang.noclassdeffounderror: org/apache/log4j/logger     @ org.docx4j.openpackaging.base.<clinit>(base.java:42)     @ variablereplace.main(variablereplace.java:61) caused by: java.lang.classnotfoundexception: org.apache.log4j.logger     @ java.net.urlclassloader$1.run(urlclassloader.java:202)     @ java.security.accesscontroller.doprivileged(native method)     @ java.net.urlclassloader.findclass(urlclassloader.java:190)     @ java.lang.classloader.loadclass(classloader.java:306)     @ sun.misc.launcher$appclassloader.loadclass(launcher.java:301)     @ java.lang.classloader.loadclass(classloader.java:247)     ... 2 more java result: 1
