Question

I am trying to read the xmlsx file using poi API, when i execute the code in my local system its executes fine but in server it throws exception

NoSuchMethodError: org.apache.poi.util.IOUtils.copy(Ljava/io/InputStream;Ljava/io/OutputStream;)

i am currently using the latest POI api.

Answer 1

Looks like there also is an earlier version of POI on the classpath in which that method did not exist yet. See this question in the POI FAQ .

传递依赖关系可能存在问题，或者与您部署在其中的servlet容器中的现有库存在冲突。
