Sharepoint API for Java

Question

Steps that I am trying to perform the following steps through Java:

1) Connect to a sharepoint site with a given URL.

2) Get the list of files listed on that

Answer 1

With SharePoint 2013, the REST services will make your life easier. In previous versions, you could use the good old SOAP web services.

For instance, you could connect to a list with this query on the REST API:

http://server/site/_api/lists/getbytitle('listname')/items

This will give you all items from that list. With OData you can do additional stuff like filtering:

$filter=StartDate ge datetime'2015-05-21T00%3a00%3a00'

Additionally, you can provide CAML queries to these services, allowing you to define detailed queries. Here's an example in Javascript:

var re = new SP.RequestExecutor(webUrl);
re.executeAsync({
url: "http://server/site/_api/web/lists/getbytitle('listname')/GetItems",
method: 'POST',
headers: { 
    "Accept": "application/json; odata=verbose",
    "Content-Type": "application/json; odata=verbose"
  },
body: { 
    "query" : {
      "__metadata": {
        "type": "SP.CamlQuery" 
      },
      "ViewXml": "" +
        "" + query + "" +                       
      ""
    }
  },
success: successHandler,
error: errorHandler
});

If all of this doesn't provide enough flexibility, you might as well take these list items in memory and do additional work in your (server side) code.
