SCTP-server Example Problem

[Armache Antoni]

Hi guys, hope everyone is doing good.

I am trying to create a Sctp-server from scratch with jainslee from the following link:

https://github.com/RestComm/gmlc/blob/master/test-suite/src/main/java/org/mobicents/protocols/ss7/gmlc/load/Client.java

Everything is working okey but i have a problem on SCCP layer, whenever i try to add a RULE , am receiving the following error :

  --------

java.lang.NoSuchMethodError: org.mobicents.protocols.ss7.sccp.Router.addRule(ILorg/mobicents/protocols/ss7/sccp/RuleType;Lorg/mobicents/protocols/ss7/sccp/LoadSharingAlgorithm;Lorg/mobicents/protocols/ss7/sccp/OriginationType;Lorg/mobicents/protocols/ss7/sccp/parameter/SccpAddress;Ljava/lang/String;IILjava/lang/Integer;ILorg/mobicents/protocols/ss7/sccp/parameter/SccpAddress;)V

        at net.inmobiles.xxxSLEESbb.initSCCP(xxxSLEESbb.java:223)

---------

on line  xxxSLEESbb.java:223 ..... i have the following code:

this.sccpStack.getRouter().addRule(1, RuleType.SOLITARY, LoadSharingAlgorithm.Bit0, OriginationType.REMOTE, pattern, "K", 1, -1,

null, 0, null);

Please anyone could help or show me what am doing wrong....... 

Thanks

Hi,

seems to be version mismatch ("java.lang.NoSuchMethodError: ")

Hi Ibrahima 

When u say version mismatch....  u mean my sccp-dependency version ?

<!-- https://mvnrepository.com/artifact/org.mobicents.protocols.ss7.sccp/sccp-impl -->

<dependency>

    <groupId>org.mobicents.protocols.ss7.sccp</groupId>

    <artifactId>sccp-impl</artifactId>

    <version></version>

</dependency>

I am currently using the latest version ? Should I downgrade version ?

I managed to solve the problem of SCCP layer, i have downgraded the version of sccp dependency now its okey..... but i am back to SCTP layer, i am receiving an error about Channel connection is closed....

this is the error :

08:45:30,620 ERROR [org.mobicents.protocols.sctp.SelectorThread] (Thread-205) Error while selecting the ready keys: java.nio.channels.ClosedChannelException

        at java.nio.channels.spi.AbstractSelectableChannel.register(AbstractSelectableChannel.java:197)

        at java.nio.channels.SelectableChannel.register(SelectableChannel.java:280)

        at org.mobicents.protocols.sctp.SelectorThread.run(SelectorThread.java:111)

        at java.lang.Thread.run(Thread.java:748)

Do i have to change my SCTP dependecy which is (org.mobicents.protocols.sctp.ManagementImpl) with (org.mobicents.protocols.sctp.netty.NettySctpManagementImpl)  ?

Hi guys i have solved the ClosedChannelException error, but now i am having an error about Rule in sccp layer?

Hi Armache,

good to know that you fixed all yourself,

for your last error people may help you "quickly" if you shared your config files and/or explain what is the config you want to achieve.

Best regards and RestComm-ing!

Thanks Ibrahim for the follow-up,

 1/ 

Firstly i am confused about this error regarding the sccp-rule.... before starting this project of building an sctp-client from scratch with jainslee.

 I was using wildfly-10.1.0.Final in (server170) and (server168) then created an SS7 CLIENT_SERVER-association between them through the following files: 

/wildfly-10.1.0.Final/standalone-ss7/data/Mtp3UserPart_m3ua1.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SccpStack_sccpressource2.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SccpStack_sccprouter2.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SCTPManagement_sctp.xml

Both client and server were able to communicate  and send message without having sccp-rule problem..... i never had this problem in this situation..... 

kindly check the following files: data-config-170.zip and data-config-168.zip  100 % WORKING....

2/ 

Now I have deleted all these files in 168CLIENT inside 

/wildfly-10.1.0.Final/standalone-ss7/data/Mtp3UserPart_m3ua1.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SccpStack_sccpressource2.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SccpStack_sccprouter2.xml

/wildfly-10.1.0.Final/standalone-ss7/data/SCTPManagement_sctp.xml

and created a CLIENT-SCTP-SERVER from scratch with jainslee and deployed my SBB in /wildfly-10.1.0.Final/standalone/deployments/....... on successful deployment my SBB is creating these config files in the following path :

/wildfly-10.1.0.Final/bin/Client_sctp.xml

/wildfly-10.1.0.Final/bin/MapLoadClientSccpStack_sccprouter2.xml

/wildfly-10.1.0.Final/bin/MapLoadClientSccpStack_sccpresource2.xml

/wildfly-10.1.0.Final/bin/ClientM3UA_m3ua1.xml

Please note that the association has been established between 170SERVER and 168CLIENT and i made a pcap to check if 168CLIENT is sending INIT and receiving ACK...... Everything is okey from here on ... But whenever i tries to send message from 168CLIENT to 170SERVER with the same configuration done in above example [ 1/ ] i am receiving sccp-rule error..... kindly check the following files: scratch-data-config-168.zip...... 50% WORKING

------------------------------------------------------------

So my question is this ...... why example 1 is working without problem and example 2 is giving me error ? even though i have followed the same configuration from example 1....... the only changes happening here is 168CLIENT has been build from scratch not from wildfly SS7 stack.

Do i have to remove 170SERVER config files from wildfly SS7 and build it from scratch as well like i did with 168CLIENT ? so in other words both client and server will be build from scratch with jainslee and not wildfly SS7 stack ?

Does it matter one side using config files from wildfly SS7 stack and other side not using it ?

Please guys any help will be much appreciatted .

Hi guys,

I found the issues with this SCCP RULE problem.......  when i am deploying my SBB on wildfly all layers get configured in the following directory [ /wildfly-10.1.0.Final/bin/ ] Except the layer were the SccpRule get configured....... its seems like wildfly is ignoring this config file when i am deploying my SBB in [ /wildfly-10.1.0.Final/bin/MapLoadClientSccpStack_sccprouter2.xml ]  and it keep reading the old location file in :/wildfly-10.1.0.Final/standalone-ss7/data/SccpStack_sccprouter2.xml    ........ 

So how can i force wildfly to read this file location [   /wildfly-10.1.0.Final/bin/MapLoadClientSccpStack_sccprouter2.xml  ] on deployement  and not the old file location?

Hello Antoni,

What do you want to do exactly ?

is it to answer on idp continue and customize camel answer ?

in this case you have camel gateway which works really great !!!

https://www.restcomm.com/docs/core/camelgw/CAMEL_Gateway_Installation_Guide.htm

you can download it https://github.com/RestComm/camelgateway/releases/latest

and i can help you to customize it !

Hi Antoni,

In "initSCCP()" after creating sccpStack and before start() you can use

this.sccpStack.setPersistDir(***your path ***).
