Subject C2.2: Upload throws NullPointerException
Date Thu, 26 Apr 2007 17:18:51 GMT
Hi!

  I've got problems to upload a xml to cocoon. I want to transfer a
  file with a simple <input type="file" name="antrag" /> and suffer a
  NullPointerException.

  The Exception is only visible with activated debug-filter. But when
  the debug filter is deactivated, the upload doesn't work either.

  I work with a snapshot-release of last night with an applied patch
  to AbstractProcessingPipeline.java (reenabled
  environment.setStatus(HttpServletResponse.SC_OK); )

  OS: Win XP SP2
  Server: Jetty

  Does anybody have an idea where to search?

regards

  Martin.

And the properties:

# Causes all files in multipart requests to be processed.
# Default is true but the maximum allowed size is kept small for security reasons.
# Unsupported values will be interpreted as false.
org.apache.cocoon.uploads.enable=true

# This parameter allows to specify where Cocoon should put uploaded files.
# The path specified can be either absolute or relative to the context
# path of the servlet. On windows platform, absolute directory must start
# with volume: C:\Path\To\Upload\Directory
#
# The default directory is "upload-dir" in the work-directory
#org.apache.cocoon.uploads.directory=d:/temp/cocoonuploads

# Causes all files in multipart requests to be saved to upload-dir.
# Default is true for security reasons.
# Unsupported values will be interpreted as false.
org.apache.cocoon.uploads.autosave=true

# Specify handling of name conflicts when saving uploaded files to disk.
# Acceptable values are deny, allow, rename (default). Files are renamed
# x_filename where x is an integer value incremented to make the new
# filename unique.
org.apache.cocoon.uploads.overwrite=rename

# Specify maximum allowed size of the upload. Defaults to 10 Mb.
# Set here to a very low 100 kb to allow samples to run.
