Can you share the Servlet code you are trying to read the file input stream? and also share the error/exception messages.
Usually, there will be 2 multipart parameters you need to set as part of your Servlet configuration. I guess the default max size is 1MB, the below example is to set 30MB max size.
multipart.maxFileSize=30Mb
multipart.maxRequestSize=30Mb
If you share the Servlet code you are reading the files and exception details, maybe I can try to provide the full solution.
