Quick Start
在上一章，掌握了安裝sip server，kapanga，然后寫(xiě)了一個(gè)注冊(cè)的機(jī)制。這張寫(xiě)一個(gè)網(wǎng)頁(yè)觸發(fā)invite的事件，呼叫客戶(hù)端。
首先建一個(gè)dynamic web project，叫做Oops_Sip_02，然后修改WebContent，改為invite，修改properties，把Default output folder改為：Oops_Sip_02/invite/WEB-INF/classes，刪除build目錄，最后整個(gè)項(xiàng)目為：
修改.classpath文件，增加3個(gè)引用：注意這3個(gè)引用是你安裝目錄下的。
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jdk150_06"/>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>
<classpathentry kind="lib" path="C:/bea/sipserver30/server/lib/wlss/wlss.jar"/>
<classpathentry kind="lib" path="C:/bea/sipserver30/server/lib/wlss/sipservlet.jar" sourcepath="C:/bea/sipserver30/server/lib/wlss/sipservlet.jar"/>
<classpathentry kind="lib" path="C:/bea/sipserver30/server/lib/weblogic.jar"/>
<classpathentry kind="output" path="invite/WEB-INF/classes"/>
</classpath>
在src目錄下面增加2個(gè)文件
httpControlServlet
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class httpControlServlet extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doAction(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doAction(request, response);
}
private void doAction(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{
String sip = request.getParameter("sip");
sipControlServlet.DoConnection(sip);
RequestDispatcher rds;
rds = getServletContext().getRequestDispatcher("/index.jsp");
rds.forward(request, response);
return;
}
}
sipControlServlet
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.sip.*;
import com.bea.wcp.sip.util.TransportUtil;
public class sipControlServlet extends SipServlet
{
private static Address myAddress;
private static SipFactory factory;
public void init(ServletConfig cfg) throws ServletException
{
super.init(cfg);
factory = (SipFactory) getServletContext().getAttribute(
SipServlet.SIP_FACTORY);
String uri = "sip:oops@localhost:5062";
myAddress = factory.createAddress(uri);
System.out.println("Oops! Sip Server Demo 2");
}
public static void DoConnection(String sip) throws ServletException,
IOException
{
SipApplicationSession appSession = factory.createApplicationSession();
Address to = factory.createAddress("sip:" + sip);
SipServletRequest invite = factory.createRequest(appSession, "INVITE",
myAddress, to);
invite.send();
System.out.println("Connection successful!");
}
protected void doResponse(SipServletResponse resp) throws ServletException,
IOException
{
resp.createAck().send();
}
}
在invite/WEB-INF下面建2個(gè)文件：
sip.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sip-app
PUBLIC "-//Java Community Process//DTD SIP Application 1.0//EN"
"http://www.jcp.org/dtd/sip-app_1_0.dtd">
<sip-app>
<display-name>Oops Sip Server Quick Start 2</display-name>
<distributable />
<servlet>
<servlet-name>sipControlServlet</servlet-name>
<servlet-class>sipControlServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- system user for the run-as element for Registrar -->
<security-role>
<role-name>system-user</role-name>
</security-role>
</sip-app>
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>testsender</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>httpControlServlet</servlet-name>
<servlet-class>httpControlServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>httpControlServlet</servlet-name>
<url-pattern>/http.oops</url-pattern>
</servlet-mapping>
</web-app>
在invite目錄下添加index.jsp
<html>
<body>
<form name="form_sip" action="http.oops"
method="post"><input name="sip" value="user1@192.168.0.130:5061"
type="text" style="width: 240px"><input type="submit"></form>
</body>
</html>
最后整個(gè)目錄變?yōu)椋?br />
大概解說(shuō)一下：用戶(hù)網(wǎng)頁(yè)輸入sip，傳遞給后臺(tái)httpservlet，其調(diào)用sipservlet的靜態(tài)方法，創(chuàng)建一個(gè)會(huì)話到用戶(hù)。
現(xiàn)在吧項(xiàng)目部署在bea sip server上面，方法參考前面的文章。然后在瀏覽器輸入：
http://localhost:7001/invite
之后打開(kāi)kapanga，在點(diǎn)擊網(wǎng)頁(yè)
完成！
