Java Backed Web Scripts - File Upload

mocathe1st — Mon, 21 Jul 2008 16:04:13 GMT

Hi all,I've been trying to create a Java Backed Web Script that will allow clients to upload files via POST. The main problem I'm getting is that no parameters seem to be present in the request object when I send a form as a multipart/form-data. I've written the following code to test if anything's

i am not sure what's going on, but in your test page, are you setting enc-type?

From:
http://htmlhelp.com/reference/html40/forms/input.html

The following example allows the user to upload an HTML document for validation:

<FORM METHOD=post ACTION="/cgi-bin/validate.cgi" ENCTYPE="multipart/form-data">
<P>Select an HTML document to upload and validate. If your browser does not support form-based file upload, use one of our <A HREF="methods.html">alternate methods of validation</A>.</P>
<P><INPUT TYPE=file NAME="html_file" ACCEPT="text/html"></P>
<P><INPUT TYPE=submit VALUE="Validate it!"></P>
</FORM>

Yes, I'm setting ENCTYPE for the file upload. I assume that this means that I need a different set of classes for picking up the file at the Alfresco end. With the standard Spring Framework there is a MultiPartHttpRequest class that I would normally use, but this doesn't pick up the parameters when I use it with Alfresco.

I still haven't found a solution for this, any help would be greatly appreciated.

Anyone got any ideas on this?

I still haven't found a solution… I'm probably missing something really obvious, but I'm struggling to find any info on file uploading with the Java Backed Web Scripts. Is this even possible using Java Backed Web Scripts?

I don't know if this is related, but I'm having a similar problem getting formdata parameters to my Javascript web scripts. I'm using Java and JUnit as a test harness and sending POST's with formdata to my web scripts, but by the time it gets into the web script, the formdata item is emtpy. In order for me to access the data, I have to use the args array.

The issue you're having is a generic Java Servlet issue in fact; that multi-part HTML forms do not end up visible in your servlet. Basically, you can do two things:
1. Use javascript (the formdata does support multi-part forms)
2. Use a servlet filter to pre-process the multi-part data for you
