Class MultipartFilter

java.lang.Object

com.jalios.jcms.servlet.JcmsServletFilter

com.jalios.jcms.upload.MultipartFilter

All Implemented Interfaces:

javax.servlet.Filter

public class MultipartFilter
extends JcmsServletFilter
implements javax.servlet.Filter

Filter for automatic file upload processing. it wrapper HttpServletRequest to pass any form parameters in usuall form (normally they are not accessible cause JSDK web container are not required to implement RFC1867).

Use filter attribute "uploadDir" to set temporary directory. If there is no attribute, then create a sub directory UPLOAD_DIR in javax.servlet.context.tempdir path.

Use filter attribute "sizeMax" to set max size otherwise use 2048000000L.

Use filter attribute "sizeThreshold" the threshold, in bytes, below which items will be retained in memory and above which they will be stored as a file.. Default value is 4096.

FIXME:

FileItem access is done through attributes. By default they are named after the form field name. However you are allowed to supply attributePrefix and/or attributeSuffix that will be used to "decorate" the attribute name. Request parameter is still set with a fake value defined by filter attribute "fakeParam".
