org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException

Question

How to handle

java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field fileName exceeds its maximum permitted size of 3145728 bytes.

This happens after uploading a file which is bigger than maxFileSize limit in servlet @MultipartConfig. Is there a way to load in browser custom error page or something else because after that client recievs

The connection was reset

I'm guessing the normal servlet error-page mechanism should catch this, so add this to web.xml:

<error-page>
    <error-code>500</error-code>
    <location>/internalerror.html</location>
</error-page>

or to catch any error code, just leave out the <error-code> tag:

<error-page>
    <location>/anyerror.html</location>
</error-page>
