Struts2 fileUpload and glassfish upload file limit repair

Struts2 upload file based on Apache FileUpload components, after importing FileUpload, small file upload is normal, but upload large files but found that there is a limit of 2M bytes, query struts2 official information to be modified struts.xml to set, Set it to 20M by pretending to adjust it.

	<struts>
		<constant name= "struts.multipart.maxSize" value= "20971520"/>
	</struts>

The problem should have ended, but found that Glassfish also has the Max Post Size limit, so also modified, after restarting the application server, upload files are normal.

GlassFish Max Post Size modified at configurations, Network Config, Protocols, Http-listener, HTTP-M Ax Post Size
