这是怎么回事？那log4j呢？

Answer 1

暂时不要担心Log4j的事情。这只是告诉您Log4j框架找不到它的配置。没有它它也能正常运行。

重要的一点是

Caused by: java.lang.NoSuchMethodError: org.apache.ws.commons.schema.XmlSchema.getTypeByName(Ljava/lang/String;)Lorg/apache/ws/commons/schema/XmlSchemaType;

对我来说这说明你有一些库不匹配。您的类路径中有一些库与Axis的需求不匹配(很可能是旧版本的库)。检查Axis的依赖项与您正在使用的运行环境( JVM版本和类路径上的库)。
