使用Axis2 wsdl2java生成代码时抛出InvocationTargetException与NullPointerException

问题详情 #

尝试使用Axis2（1.6.1至1.8.2版本）的wsdl2java工具从WSDL文件生成Java源码，执行命令：

.\wsdl2java.bat -uri %PATH_TO_XML% -p org.apache.axis2.axis2userguide -d adb -s -u

执行后抛出如下异常：

Using JAVA_HOME:    C:\Program Files\Java\jdk1.8.0_271
Retrieving document at 'D:\Documentos\Axis\axis2-1.8.2\bin\ARIBankService.xml'.

使用的WSDL文件为ARIBankService.xml。

期望目标 #

成功生成Java源码，用于调用该Web服务并将其转换为REST类型服务。
