The message here is either a Request or a Response.

The sample code is as below:

if(message.getContentLength() > 0)

{

       String contentType = message.getContentType();

       message.setContentType("text/plain"); //The SIP Container only can realize this type

       String sdpContent = message.getContent().toString();

       ......// OK,now it just need some operation on String,as the code below

       private void addSDP(SipServletMessage re, String sessionID) {<br /> try {<br /> re.setContentType("text/plain");<br /> String regEx1 = "o=.+";<br /> String regEx2 = "c=.+";<br /> String newstr1 = "o=SuperServlet %s IN IP4 %s";<br /> String newstr2 = "c=IN IP4 0.0.0.0";<br /> if (re.getContent() != null) {<br /> String sdp = re.getContent().toString();<br /> sdp = replace(sdp, regEx1, newstr1);<br /> sdp = replace(sdp, regEx2, newstr2);<br /> sdp = String.format(sdp, sessionID, MusicServerIP);<br /> re.setContent(sdp, "text/plain");<br /> re.setContentType("application/sdp");<br /> log("TestServlet: addSDP : Result is " + sdp);<br /> } else {<br /> }<br /> } catch (Exception e) {<br /> e.printStackTrace();<br /> }<br /> }<br /> public static String replace(String str, String regex, String newStr) {<br /> Pattern p = Pattern.compile(regex);<br /> Matcher m = p.matcher(str);<br /> String s = m.replaceAll(newStr);<br /> return s;<br /> } 

       message.setContent(sdpContent,"text/plain");

       message.setContentType(contentType);
