Hi,

It might be a server configuration issue. Have you tried configuring something like the following in your web.xml?

<multipart-config>
    <max-file-size>100000000</max-file-size> <!-- almost 100 MB (not exactly) -->
    <max-request-size>100000000</max-request-size>
    <file-size-threshold>0</file-size-threshold>
</multipart-config>
