I am trying to use Apache-Commons Httpclient to send a MultipartPost request to a web server!  The server is not receiving the file I am sending!  I would like to know how to look at a trace of everything being sent by my MultipartPost!  That shows all the parts of the MultipartPost!  With each part's value exactly as the server sees the request coming to it!

The server is using Struts to receive the file!

iterate thru each part and display its content.

I did create a Part[] array and ran the ".getparts" method to copy the part attributes into an array!  The problem is that I do not know how to display its content.  What method do I use!  I can get all sorts of attributes about the part but not the content!

I meant I do not know how to display an individual part's content.  The Part[] array contains attributes of the part... yet there is no method to display the content or value of each individual part!

Better use HTTPLook. It can give you all u want without programming to do.
You will find that using HTTPClient, the request contains much lesser attributes and a different data when u send a multipart request.

There is another way also, to see the content of your Part objects.
Download cocoon.jar from
http://cvs.sourceforge.net/viewcvs.py/krysalis/krysalis-wings/lib/core/Attic/cocoon.jar?rev=1.2

Then include it in your classpath and then this code will work :)
####
byte[] partContent = org.apache.cocoon.utils.IOUtil.objectToBytes(Part[0]);
System.out.println(partContent.toString());

I tried adding the cocoon.jar to my classpath and I got the error below:

hi,

ok, Part doesn't implement serializable interface.
You can do this to see all the content your parts have. Try this

part[index].send(System.out);

All the data with header will print on console. Tell me if that helped or not..:)

Thanks! this last solution allowed me to view the data being sent to the server in the exact same format that the server sees it!  This worked well for me!
