Classes and Methods

SIP Servlets  2-11

// Create a SipURI, set the port, the lr, and the transport

// protocol parameter

SipURI myURI;

myURI = sipFactory.createSipURI("bob", "10.0.0.10");

myURI.setPort(5072);

myURI.setLrParam(true);

myURI.setTransportParam("udp");

SIP addresses found in headers, such as the From, To, and Contact headers, are stored 
as javax.servlet.sip Address objects. As shown in 

, the object 

holds, beside the URI, an optional display name and a set of name-value parameters. 

Address contactAddress;

String displayName;

try

{

  // Get the contact address

  contactAdress = req.getAddressHeader("Contact");

  displayName = contactAdress.getDisplayName();

}

catch (ServletParseException spe)

{

  // Handle exception

}

// Create a new address

Address myNewAddress;

myNewAddress = sipFactory.createAddress(URI, "Bob's display name");

myNewAddress.setParameter("myparameter","42");

The content of myNewAddress in the preceding example is as follows:

DisplayName: "Bob’s display name"

URI: <sip:bob@example.com;lr>;

parameter myparameter: 42

The Address class offers the following methods:

■

getDisplayName()

■

setDisplayName()

■

getURI()

■

setURI()

■

clone()

■

toString()

When working with the SIP Servlet API, many SIP details are hidden and performed 
automatically by the OCMS SIP Application Server. 

■

When the transport protocol is UDP, retransmissions are handled automatically.
