Method Detail

doPost

protected void doPost(javax.servlet.http.HttpServletRequest req,
          javax.servlet.http.HttpServletResponse resp)
               throws IOException

Perform an HTTP-POST, which corresponds to the basic CRUD operation "create" according to the generic interaction semantics of HTTP REST. The operation will be executed against the target namespace per the URI.

 POST [/namespace/NAMESPACE]
 ...
 Content-Type: 
 ...
 
 BODY
 

Where BODY is the new RDF content using the representation indicated by the Content-Type.

-OR-

 POST [/namespace/NAMESPACE] ?uri=URL
 

Where URI identifies a resource whose RDF content will be inserted into the database. The uri query parameter may occur multiple times. All identified resources will be loaded within a single native transaction. Bigdata provides snapshot isolation so you can continue to execute queries against the last commit point while this operation is executed.

Overrides:

doPost in class javax.servlet.http.HttpServlet

Throws:

IOException
