[sword-app-tech] Need some clarification on SWORD Servlet Client code

[Debashree P. <dp...@ol...>]

Hi Stuart,

I've been looking into the SWORD client source code lately.  I have 
difficulty in figuring out one thing in the ServletClient.java. Since 
you are the author of the code, I am hoping you will be able to explain it.

In the method doDeposit(), you are processing the file to be 
deposited in the following code segment:

String fname = tempDirectory + File.separator + "ServletClient-" + counter++;
if ((contentDisposition != null) && (!contentDisposition.equals(""))) {
         fname = tempDirectory + File.separator + contentDisposition;
}
File uploadedFile = new File(fname);
item.write(uploadedFile);

Here the tempDirectory is being set in the Init() method of the 
servlet. Since 
getServletContext().getInitParameter("upload-temp-directory") 
evaluates to null,  the tempDirectory  gets it's value from: 
tempDirectory = System.getProperty("java.io.tmpdir");
I printed out it's value, and it was set 
to:    [tomcat]/webapps/works/xmlui/cocoons/files/

Hence, the fname came out as
         [tomcat]/webapps/works/xmlui/cocoons/files//ServletClient-0 
or ...../ServletClient-1,  etc. depending on the counter value.

Why do you upload it to under xmlui? How does it go to the database 
from there? I will really appreciate some clarification on these.


Ultimately, my goal is to: Allow users of our dspace repo. to 
remotely perform a bulk-submission using the SWORD webservice.
Currently, your SWORD webservice is able to remotely post only a 
single file at a time. I am interested in modifying it so that it 
will be able to post multiple files.  For example,  I will have a 
test.zip directory (folder) that will contain several files like the 
example.zip (provided by you for testing).

I want the user to enter the test.zip into the "Choose Package" field 
in depositform.jsp. When user clicks on the deposit button, I need to 
extract the zipped files from inside of test.zip one by one and 
process each for uploading and depositing. I believe, that I will 
have to work on ServletClient.java. Do you have any suggestions?

Many thanks for taking the time to read the above,
