How can I upload a file to a Sharepoint Document Library through SOAP web services using Java?

Question

I'm trying to upload a document to a document library using the SP 2010 SOAP copy web service from Java.

Any idea how to do this in Java?

Here's the code I have so far:

String[] destinationUrls = {mySiteUrl + "/" + listName + "/" + fileName};

// Set up the metadata
FieldInformation titleInfo = new FieldInformation();
titleInfo.setDisplayName("Title");
titleInfo.setInternalName("Title");
titleInfo.setType(FieldType.TEXT);
titleInfo.setValue("DocumentTitle");

// Content type meta
FieldInformation contentTypeInfo = new FieldInformation();
contentTypeInfo.setDisplayName("Content Type");
contentTypeInfo.setInternalName("Content Type");
contentTypeInfo.setType(FieldType.CHOICE);
contentTypeInfo.setValue("Document");

FieldInformation[] metadata = { titleInfo, contentTypeInfo };

// Copy the new file to the portal document list
Long copyIntoResult;
CopyResult[] result;

client.copyIntoItems("http://null", destinationUrls, metadata, fileBytes, copyIntoResult, result);

But Eclipse reports that my use of copyIntoItems "in the type CopySoap is not applicable for the arguments". Obviously, my supplied arguments are incorrect.

The WSDL-generated signature for the copyIntoItems() method looks like:

copyIntoItems(String, DestinationUrlCollection, FieldInformationCollection, byte[], Holder<Long>, Holder<CopyResultCollection>);

But those Collection types and Holder only supply protected accessors, i.e. no way to set input state.

Can anyone help me solve this problem?

I didn't read the generated code comments close enough. Here's the solution:

DestinationUrlCollection destinationUrls = new DestinationUrlCollection();
destinationUrls.getString().add(_siteUrl + listName + "/" + fileName);

// Set up the metadata
// Remark: don't set the Name field, because this is the name of the document
FieldInformation titleInfo = new FieldInformation();
// (same as before)

// Content type meta
FieldInformation contentTypeInfo = new FieldInformation();
// (same as before)

FieldInformationCollection metadata = new FieldInformationCollection();
metadata.getFieldInformation().add(titleInfo);
metadata.getFieldInformation().add(contentTypeInfo);

// Copy the new file to the portal document list
Holder<Long> copyIntoResult = new Holder<Long>();
Holder<CopyResultCollection> result = new Holder<CopyResultCollection>();

client.copyIntoItems("http://null", destinationUrls, metadata, fileBytes, copyIntoResult, result);

But it's soo quirky. destinationUrls.getString().add()? And Holder<Long> as opposed to Long?

You should not have SPACE in Internal Name. Please see below the corrected content.

// Content type meta
FieldInformation contentTypeInfo = new FieldInformation();
contentTypeInfo.setDisplayName("Content Type");
contentTypeInfo.setInternalName("ContentType");
contentTypeInfo.setType(FieldType.CHOICE);
contentTypeInfo.setValue("Document");
