I am the OP. I actually have a solution running now, using JSON-RPC as the connector between Kamailio and the Java EE business logic. I am looking for an alternate solution to resolve the limitations with the RPC mechanism. Performance is not an issue at all. In-fact performance is barely a consideration for this application -- busy hour traffic is around 5 transactions per second, with the majority of the transactions being SIP MESSAGE request/response. -----Original Message----- From: sr-users-bounces(a)lists.sip-router.org [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of Alex Balashov Sent: November-24-12 3:01 PM To: sr-users(a)lists.sip-router.org Subject: Re: [SR-Users] Kamailio-Java Integration On 11/24/2012 05:56 PM, Jeremy Ardley wrote: While SIP requires sub-second precision, it does not require millisecond precision. :-) In any case, garbage collection is definitely a problem, but there are ways of optimising the JVM's GC behaviour to be more or less favourable to the task. That is definitely true, though one might argue that this is a cultural problem rather than an innate Java problem. In any case, I am not a Java programmer and am not defending Java, so please don't misconstrue my stance. I'm just saying that it might not be _wholly_ unsuitable to the task. I do not think, and have never thought, that Java is an ideal language in which to implement SIP call processing. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

I don't think Java would be a performance limitation at all, as long as it runs on a separate machine with its own processor, memory and pool of disks. If you don't like writing complex modules in C, you can always implement your business logic in your preferred high level languages (Java, C#, PHP?) and use JSON/XML based bidirectional communication over TCP to query your business node, and to parse the response you can write a Perl script which will be called from inside the Kamailio's script.

Hello, have a look at app_mono module. Apparently you can run java code embedded in Kamailio via this module - the mono interpreter seems to be able to execute java: http://www.mono-project.com/Java Cheers, Daniel On 11/25/12 1:00 AM, ron.kamailio(a)mcleodnet.com wrote: -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

If good performance and throughput were the primary concern, I'd much prefer to write something like this in C[++]. However, the original poster asked about integrating with Java, and I feel we should strive to answer the question as posed. If the question is absurd enough, it's sometimes okay to tell people, "You're simply doing it wrong," but my point is that Java isn't _that_ absurd. And regardless of what we think, it will persist in the enterprise space as the go-to software engineering ecosystem for the time being. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
