Okay, so let me pose the following scenario. I'd like to do a file
upload using a simple action (i.e. without using flows). Here's
some simple HTML for the upload
<html>
<body>
<form action="upload" method="post" enctype="multipart/form-data">
File: <input type="file" name="uploadfile" size="50">
<input type="submit"/>
</form>
</body>
</html>
The wiki gives an example action, but it doesn't work because the
API has changed for Cocoon 2.1. So let's try this:
package edu.uga.english.cantor;
// Lots of imports . . .
public class SGUpload
extends AbstractLogEnabled
implements Action, ThreadSafe {
public Map act(Redirector redirector, SourceResolver resolver,
Map objectModel, String source, Parameters par)
throws Exception {
Request request = ObjectModelHelper.getRequest(objectModel);
PartOnDisk filePart = (PartOnDisk) request.get("uploadfile");
if (filePart != null) {
getLogger().debug("Uploaded file = " +
filePart.getFileName());
} else {
getLogger().debug("File not found");
}
return null;
}
}
That compiles without incident, and I drop it (and its package tree)
into WEB-INF/classes. I need to add a line to the components
section that tells Cocoon where it is, so I put:
<map:actions>
<map:action name="sg-upload" src="edu.uga.english.cantor.SGFlow"/>
</map:actions>
I think I'm stuck trying to figure out what to put in the pipeline
(the examples online and in the book I'm using aren't exactly on
point). I realize that I can trap on <map:match pattern="upload">,
trigger the action with <map:act type="sg-upload">, and then do
whatever (presumably something as simple as "<map:read
src="static/success.html" mime-type="text/html"/>), but all I get is
404s and NullPointerExceptions.
What's the dumbest thing that can work in this situation?
Oh, and here's a possibly dumb question: Where is this getting
logged? I understand that AbstractLogEnabled is an avalon facade
for whatever logging system is in use, but I don't know where my
calls to debug() are getting written (and in any event, they're not
being written to any file in my tomcat tree).
I'm definitely a beginner with Cocoon (though not with Java and
XML). I have a complete site running on Cocoon that uses lots of
conditional logic and whatnot, but I haven't tried to do anything
fancy with it yet. I'd really like to do all my computational logic
without XSP, so if anyone knows of a lucid explanation of Actions,
I'd be much obliged.
Thanks,
Steve
