[mobicents-public] Exception while running the Player servlet example of jsr309

[Amit]

I have install the standalone media server on 192.168.10.32 IP and
application is deployed on the 192.168.10.240 IP.

when i am running the application I am getting this Exception.

Servlet 'PromptAndCollectServlet' threw an exception during
initialization.
java.lang.RuntimeException: Failed to find a local port to bound stack



I have also checked the application after changing this in the code
protected static final String PEER_ADDRESS = System.getProperty
("jboss.bind.address", "192.168.10.32");

but exception is same.

Pls tell me what I have to change or configure in code to run the
application.

The client (Servlet) will try to bind to port 2727 and server (MMS) binds to 2427. Please see if your 2727 port is free?

[Amit Bansal]

I have checked using the command "netstat -a" but it is not listed in the list means it is free before starting the server.

After starting the server it is in the list.

this is the log when server is started--

[Amit Bansal]

I have have removed the application from the server and then restarted the server then it is in the list of used ports.

It means server is using that port???

Can we change that port to other port??

thanks

[Amit Bansal]

this is list of ports those are active while server is started.

Did you say you start the MMS standalone
And then start the Sip Servlet Server which also has embedded Media Server?

If yes that means both MMS are contending for port 2427 and the one started first will get it

In order to avoid starting the embedded MMS just delete 'mobicents-media-server' from mss-1.0-SNAPSHOT-jboss-5.1.0.GA-0906091045-TECH-PREVIEW/server/default/deploy/

[Amit Bansal]

No, Sip server have not embedded Media server.

I am deploying the SIP servlet in the Sailfin Application server.

Can we change the value of this port.

protected static final int MGW_PORT = 2427;

If yes then I have to mention it some where or just change the value of this variable????

Thanks

[Amit Bhayani]

In PlayerServlet.java of media-jsr-309 example the client side MGCP stack binds to property "mgcp.stack.port" and hence change the value of CA_PORT=2727 to may be 2728 or which ever port is free.

[Amit Bansal]

I have changed the value of the CA_PORT to 5555 but it is still starting it on 2727 port??

thanks

-amit

[Amit Bhayani]

Ok realized the problem.

In PlayerServlet I am using property.put(MGCP_STACK_PORT, CA_PORT); where CA_PORT is int and it uses directly the put method of Hashtable instead of setProperty(String key, String value) of java.util.Properties

But while reading the property it uses

portString = properties.getProperty(MGCP_STACK_PORT, "2727");

getProperty checks if value Object is String, if not it returns null and hence in our case will always take default value "2727"

I have fixed this in PlayerServlet. Use it like

        Properties property = new Properties();
        property.setProperty(MGCP_STACK_NAME, "SipServlets");
        property.setProperty(MGCP_PEER_IP, PEER_ADDRESS);
        property.setProperty(MGCP_PEER_PORT, MGW_PORT);

        property.setProperty(MGCP_STACK_IP, LOCAL_ADDRESS);
        property.setProperty(MGCP_STACK_PORT, CA_PORT);

[Amit Bansal]

thanks for the help.....now example is working fine for softphone that is installed on the same machine on which servers are running.

when i have checked the example with softphone that is installed on other system...example is not working means no media is played to the softphone.

--
Thanks
amit

[Jean Deruelle]

make sure you start the server with -b <the binding ip address> like sh run.sh -b 192.168.0.10 by example. and that you sip phone is directed to that address

[Amit Bansal]

I have to start the media server like this ??

"run.bat -b 192.198.10.240"

For application server i am using the Sailfin server.

when i call to the server... call is established but media is not played but for same system softphone example is works fine.

thanks

-amit

[Jean Deruelle]

if you run everything on different machines on a local network yes that's preferrable otherwise it starts on 127.0.0.1 by default

[Amit Bansal]

If i am running the sailfin server and standalone mobicent media server on same machine but softphone is install on other machine then i have to start the media server like this??

"run.bat -b 192.198.10.240"

[Jean Deruelle]

I guess it would be better to do so as well indeed
