Filter on Sip Servlet

Hy all
I have a question for you. Is it possible to filter sip message with a personal implementation of a Filter interface (com.bea.wcp.sip.engine.server.Filter)?
Reading documentation i understan it's simple to create a filter and a FilterChain but i can't understant how it's possible to map this object on the server.
Thanks a lot for any response
Regards Gianluca Orlando

<url-pattern>/*.jsp</url-pattern> this means it will search for all the jsp's in the directory.

Sending an INVITE to my VoIP account by a SIP Servlet

I tried to make an outbound call to an ordinary landline number through my VoIP account by a SIP Servlet, but never been successful.
I tried something similar to the following:
javax.servlet.sip.SipFactory factory=(javax.servlet.sip.SipFactory) this.getServletContext().getAttribute(javax.servlet.sip.SipServlet.SIP_FACTORY);
javax.servlet.sip.SipApplicationSession appSession =factory.createApplicationSession();
to = “sip:land_line_number@my_voip_proxy_server.com”
from=”sip:my_voip_did_number:my_voip_password@ my_voip_proxy_server.com”
javax.servlet.sip.SipServletRequest invite = factory.createRequest(appSession, "INVITE", from, to);
invite.pushRoute(URI of my_voip_outbound_proxy_server.com);
invite.send();
I use Weblogic SIP server. I configured sip.xml, and everything else is correct to my knowledge.
I always get the error message something similar to “Cannot resolve path to my_voip_proxy_server.com”
(Note: When I use SJPhone softphone with my VoIP account details, it simply rings to a landline)
Is the way I incorporating my_voip_outbound_proxy_server correct?
Any help from anyone is greatly appreciated.
Thank you very much.

hi there,
I am at the same point too..
I am using a softphone called mirrial , Using Bea WEB Logic SIP Server...Deployed sar arhieve , did not define any outbound proxy in client side , did not specify default servlet name for sip server..
Is there anybody who succedded such kind of proxy calls ?
And can clarify the details if have?
Thanks

Embedding STUN server in SIP servlet application?

Hello,
I'm trying to find a good way to integrate a STUN server into my SipServer application. One approach requires that I be able to receive and process both STUN and SIP packets from the same listen port. Basically, I want to open a single listen port (like 5060) to receive UDP packets in my SIP servlet container. I'd then like to take any SIP messages I receive on that port and hand them to my SIP servlet. No problem - that's what SipServer provides out of the box. But I'd also like to receive any STUN packets and hand them off to my STUN server code for STUN activities. Anyone know of a way to accomplish this with some fancy configuration of a channel or 2? I don't know the WLS/WLSS architecture well enough to think of anything truely clever.
My coworker tells me this isn't possible, or at least not without Herculean effort and major custom coding to route packets. I sure would like to prove him wrong ;)
Thanks -
Brian.

It should certainly be possible to debug the sipServlet application in eclipse.
I use Intellij IDEA for remote debugging and here is the command I use:
%JAVA_HOME%\bin\java %JAVA_VM% %MEM_ARGS% %JAVA_OPTIONS% -Dweblogic.Name=%SERVER_NAME% -Dweblogic.ProductionModeEnabled=%PRODUCTION_MODE% -Djava.security.policy="%WL_HOME%\server\lib\weblogic.policy" -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005 weblogic.Server
I guess, what you are missing is suspend=y. Your options have a suspend=n.
cheers,
Mihir

Developing SIP Servlet using Eclipse

Dear all,
In the BEA documentation "developing SIP Servlet using Eclipse", it says:
WebLogic SIP Server 3.0
JDK 1.4.2
Ant (installed with WebLogic SIP Server 3.0)
Eclipse version 3.1
CVS client and server (required only for version control)
I want to kown it should be JDK 1.4.2 but not 1.5.0?
And how to set Ant which installed with Weblogic SIP Server in Eclipse? Because I checked that Eclipse use the Ant by defaut.
I really have problem with setting up Eclipse for developping SIP Servlet, Thanks for your help!

Dear all,
I have resolved it.
The path is not correct in the ant build file.
Thanks

SIP Server vs SIP Servlet

Hello,
Can someone let me exact what the difference between SIP Server and SIP Servlet.?
Regards,
Deepak

It's hard to be precise since "SIP Server" does not have a precise definition, but I'll try to help.
The term SIP Server can apply to any network node meant to affect a SIP session. A server can act as SIP User Agent (UA), proxy, or back-to-back UA. Nothing about the way these applications are programmed is implied by the term "SIP Server."
The SIP Servlet API (SSAPI) is a popular technology for implementing SIP applications; therefore you could say that a SIP Servlet container is a type of SIP Server. The SSAPI is specified in [JSR 289|http://jcp.org/en/jsr/detail?id=289] , and is an extension of the familiar servlet model that is also used for programming HTTP applications.
OCCAS is a SIP Servlet container, and therefore also a SIP Server.
Hope this helps,
Tom.

Sip servlet container

Thanks in advance !!

Hi Sebestian,
I could really understand the problem ,but as Far as Coding concerns the Same templates will suit for both C# and Vb.Net , So i suggest you to go through the E-Learning in SDN which is open source Go To E-Learning Sessions it was all presented in C# only , I Strongly belive after having a travel in E-Learning you would be able to work with all the objetcs
Comments and feeds back is welocmed

Custom filter calling Pipeline servlets

Hi,
Can we invoke the pipeline servlets from our custom filter without using the PageFilter, if we can please explain how to do that.
And how to get the DynamoHttpRequestServlet as passing thru the pipeline we will get Dynamo request only.

I have been following up this thread along with some other posts also from you on similar issue and thought of one approach. Although I am not sure if it is going to work or not due to any internal dependency on something which I may not know. But still you can try something like this to invoke the pipeline by calling HeadPipelineServlet from your own filter and see if it serves your purpose.
//component path to refer atg.servlet.pipeline.HeadPipelineServlet
String piplineStartServletPath = "/atg/dynamo/servlet/dafpipeline/DynamoHandler";
//your filter implementation
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
//try invoking HeadPipelineServlet
Servlet startServlet = (Servlet)Nucleus.getGlobalNucleus().resolveName(piplineStartServletPath);
if(startServlet != null)
startServlet.service(request, response);
//once HeadPipelineServlet is called check from the request attribute to see if we got the DynamoHttpServletRequest
DynamoHttpServletRequest drequest = (DynamoHttpServletRequest)request.getAttribute("atg.servlet.request");
}

Where to deploy the sip servlet

Hi,
general question: where are the servlet .class files, sip.xml and web.xml deployed to? Are there some other (configuration) files to be changed?
I have deployed all these files to C:\bea\user_projects\domains\TestDomain\sipserver\config\WEB-INF
but got just an exception.
Thx

Ok I've found out: Sip Server 3.0 expects an .war file to be stored under ../domains/domainName/autodeploy

Strange behavior when using servlet filter with simple index.htm

I am new to J2EE development so please tolerate my ignorance. I have a web application that starts with a simple index.htm file. I am using a servlet filter throughout the website to check for session timeout, redirecting the user to a session expiration page if the session has timed out. When I do something as simple as loading the index.htm page in the browser, the .css file and one image file that are associated, or referenced in the file are somehow corrupted and not being rendered. How do I get the filter to ignore css and image files??? Thank you!!

     String timeoutPage = "SessionExpired.jsp";
     public void destroy() {

          if ((request instanceof HttpServletRequest) && (response instanceof HttpServletResponse)) {

Servlet Filter

Hi, all
I work on a web application running on a Jboss server and i would like to filter all the http request in order to save it in a database. (i save those informations for manage web stats).
I suppose i may use servlet filter, but i don't know the operation of this
Does anyone could help me giving some example and the protocol to set up this on the server (file server configuration as web.xml)

Well here is what I know. I hope it helps.....
First thing is to create a class that implements the "javax.servlet.Filter" interface. But there are also other Filter interfaces that you could use depending on what you want: Filter, FilterChain, and FilterConfig.
You have to implement the init(), destroy() and doFilter() methods (I ommitted the arguments).
But most of your work will be done in the doFilter () method. You could extract request information from one of the arguments in these method and have a datasource connection to save to your back-end.
Something like :
public void doFilter( ServletRequest request, ServletResponse responce, FilterChain chain ) throws ServletException {
      HttpServletRequest httpRequest = (HttpServletRequest) request;
      backEndDelegate.saveInformation( request.getRemoteAddr(), request.getRemoteHost() );
      chain.doFilter( request, responce );
}Second, you need to configure the Filter. In the web.xml file add the following tags:
<filter>
     <filter-name>StatsFilter</filter-name>
      <description>Logs Web Stats to the back end</description>
     <filter-class>com.yourpackage.StatsFilter</filter-class>
     
      
</filter>
<filter-mapping>
      <filter-name>StatsFilter</filter-name>
      <filter-pattern>*.jsp</filter-pattern>
</filter-mapping>That is just a little example. You can associate a filter with a Servlet using the <filter-mapping> tags too. And you can also do filter chains, but I don't feel like going there.
I sure hope that it was helpful. If not then "RTFM"

Servlet Filters not following filter mapping in web.xml

Hi Experts,
I have two Servlet filters SetCharacterEncodingFilter and LASBackOfficeAuthFilter which are mapped in such a way that SetCharacterEncodingFilter gets called before LASBackOfficeAuthFilter(This is done in web.xml using filter mapping).
I have code in SetCharacterEncodingFilter init() method to read and store the few parameters from a table , it also creates a new thread to montior db changes in these paremeters . LASBackOfficeAuthFilter reads a those parameters set after SetCharacterEncodingFilter initialization. This is failing in Weblogic Version: 10.3.2.0 because the LASBackOfficeAuthFilter init method gets called before SetCharacterEncodingFilter init method.
This is filter mapping order is working fine In Web Sphere and Tomcat 6 .
The web.xml filter mapping is given below .
     <filter>
          <filter-name>LASBackOfficeAuthFilter</filter-name>
          <display-name>Scheduler Authentication Filter</display-name>
          <filter-class>com.scheduler.servlet.backoffice.LASBackOfficeAuthFilter</filter-class>
          
          <init-param>
               <param-name>PathLogin</param-name>
               <param-value>/login</param-value>
          </init-param>
          <init-param>
               <param-name>PathLogout</param-name>
               <param-value>/logout</param-value>
          </init-param>
          <init-param>
               <param-name>PathNotifications</param-name>
               <param-value>/secure/notifications</param-value>
          </init-param>
          <init-param>
               <param-name>PathSchedulerActions</param-name>
               <param-value>/secure/schedactions</param-value>
          </init-param>
          <init-param>
               <param-name>PathPing</param-name>
               <param-value>/secure/ping</param-value>
          </init-param>
     </filter>
     
     <filter>
          <filter-name>SetCharacterEncodingFilter</filter-name>
          <display-name>Scheduler Character Encoding Filter</display-name>
          <filter-class>com.scheduler.servlet.backoffice.SetCharacterEncodingFilter</filter-class>
     </filter>
     
     <filter-mapping>
          <filter-name>SetCharacterEncodingFilter</filter-name>
          <servlet-name>LASBackOfficeServlet</servlet-name>
     </filter-mapping>
     <filter-mapping>
          <filter-name>LASBackOfficeAuthFilter</filter-name>
          <servlet-name>LASBackOfficeServlet</servlet-name>
     </filter-mapping>
Any help on this would be very much appreciated .

No, regular expressions are not supported. You can specify the mapping with extensions, or with paths, not at the same time in the same mapping specification. However, you can specify two servlet mappings, one with extension, and one with path.
The exact wording from the spec (2.4) is as follows:
In the Web application deployment descriptor, the following syntax is used to define
mappings:
• A string beginning with a ‘/’ character and ending with a ‘/*’ suffix is used
for path mapping.
• A string beginning with a ‘*.’ prefix is used as an extension mapping.
• A string containing only the ’/’ character indicates the "default" servlet of
the application. In this case the servlet path is the request URI minus the context
path and the path info is null.
• All other strings are used for exact matches only.
