I am looking for a way to integrate Java business logic with Kamailio to influence routing decisions, add/remove/modify headers, record accounting-related information, etc. A while back there was a project named WeSIP, but it doesn't appear to active anymore.
Is anyone doing something like this now, or any ideas or suggestions?
Thanks,

WeSIP does indeed seem defunct.
I suppose one option is to build a SIP redirect server using Java SIP Servlets that pumps info back to Kamailio:
http://docs.oracle.com/cd/E13153_01/wlcp/wlss40/javadoc/jsr289/index.html
... but then, one might ask, what do you need Kamailio for? :-)
Otherwise, I can't readily think of any alternatives that strike me as economical. You could do any number of things, in principle, like write a Kamailio module that talks over a network socket to Java middleware, or use another embedded language/API Kamailio does actively support, like Lua, to talk to your Java business layer. However, I would guess that is probably not cost-effective.

Slow Java coupled with real-time SIP protocol? Hmm... Not viable to my point of view.

Despite the stereotype, Java actually performs quite well, and is used in highly concurrent, real-time environments like telephony extensively. I think the stereotype about slow interpreted languages belongs to the first era of Java (1996-2000(?)), back when it had green threads and so on.
Having said that, it is true that the JVM consumes a lot of resources just to run at all, and that the bureaucratic fashions of Java are chiefly an affectation of the enterprise world. However, once it spools up and gets going, Java is quite fast, and adequate for SIP. It has posted comparable benchmarks to C for many scientific computing applications for years now.
Initially, I was as surprised by this as you are.

A problem with Java is garbage collection. Every now and then the application slows down. This is not good for real-time applications requiring millisecond precision.
There are plenty of other problems with Java as well - startup is usually very slow. Applications are almost always bloated. And the Java programming culture of 'throw more iron at it' inevitably produces yet more bloat.

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.

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.

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.

Two main issues are that there is a size limitation with the payload which can be carried with the RPC mechanism (limited to the size of a PV), and that route block processing does not continue after calling the jsonrpc functions.

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:

I don't want to start language holy war, but I can't accept a programming language which has operator "new", but doesn't provide operator "delete". Garbage collection? Yes, it runs from time to time. Usually at the worst moments of time when precious CPU cycles are vital to run actual business logic code.

That is certainly true, and I share your distaste for the lack of manual memory management. 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.

If your Java business logic is reachable via HTTP you can use the XHTTP module to make HTTP requests to your web service.

I did end-up using the http_query() function (and {s.escape.param} for parameter url-encoding) to send an HTTP request to a Java web server which has access to the business logic. The server returns the routing data in JSON format so I used the json_get_field() function to pull-out the field data.
I makes a great solution for my application. Thanks for the suggestion Klaus.

I've build an application app_java - Java Native Interface support for Kamailio. It is an alpha version. Works with kamailio >= 3.2.
A code isn't in main release right now. You can download it: http://voipgroup.org.ua/kamailio/dev/kamailio_app_java_v0.1a.tar.gz
I would be a very grateful if somebody will test this and report about a test usage (and/or bug reports).

As expected, a consistent list of dependencies, but I guess that people using java would have those installed anyhow :-)
Is KamExec(...) running config functions exported by the modules? Maybe it should be more explicit, eventually with an example. I haven't looked at the code, just mentioning here in case it is unknown, config functions exported by modules have a special mechanism named fixup to convert parameters to custom structures. You should be careful with that because can result in memory leaks if used from embedded languages.

As expected, a consistent list of dependencies, but I guess that people using java would have those installed anyhow :-) Is KamExec(...) running config functions exported by the modules? Maybe it should be more explicit, eventually with an example. I haven't looked at the code, just mentioning here in case it is unknown, config functions exported by modules have a special mechanism named fixup to convert parameters to custom structures. You should be careful with that because can result in memory leaks if used from embedded languages.Yes, I'm using fexport->fixup() to all arguments.
You should use also the free fixup function when available. However, there are many functions implementing a fixup() that dynamically allocates memory and don't provide a free fixup function. So the potential of memory leak is there. If you know what functions you are calling from Java and they are mem leak safe, then all is fine. But it is not valid for all config functions.
That's why for Lua, we exported directly many inter-module API functions.
