Hi,everyone
I'am freshmen in DSpace development. My library has done development based on
DSpace 1.8 for three years ( our institute repository: http://ir.pku.edu.cn).
Recently we want to migrate to a higher version and I join this activity.
Now, I have a problem with the sword version 2 submission. ( I can submit
package with sword version 1 succussfully, but fail for version 2 no matter
whether I use DSpace 1.8 or higher version such as 4.2).
Following is the code (the example.zip is download from
http://sword-app.svn.sourceforge.net/viewvc/sword-app/dspace/trunk/example/example.zip
) :
----------------------------------------------------------------------------------------------
String sdIRI = "http://162.105.134.229:8080/swordv2/servicedocument";;
String userName = "xxxxxxxxxxx"; //I hide the user name
String password = "xxxxxxxxxxx"; //I hide the password
String file = "C:/Users/luopc/Desktop/dspace/example.zip";
Deposit deposit = new Deposit();
deposit.setFile(new FileInputStream(file));
deposit.setMimeType("application/zip");
deposit.setFilename("example.zip");
deposit.setPackaging("http://purl.org/net/sword/package/METSDSpaceSIP";);
deposit.setMd5(Test2.getMd5ByFile(new File(file)));
deposit.setInProgress(true);
deposit.setSuggestedIdentifier("abcdefg");
AuthCredentials auth = new AuthCredentials(userName, password);
SWORDClient client = new SWORDClient();
ServiceDocument sd = client.getServiceDocument(sdIRI, auth);
SWORDCollection col = sd.getWorkspaces().get(0).getCollections().get(0);
DepositReceipt receipt = client.deposit(col, deposit,new
AuthCredentials(userName, password));
----------------------------------------------------------------------------------------------
However, I always get the following exception:
----------------------------------------------------------------------------------------------
INFO [main] (SWORDClient.java:400) - Deposit request on

Can somebody help us? We have been puzzled by this problem for a long time.
