Of course!
I have tested the build below against my own test setup, with the following results:
SCO: Ok (creature persisted to file)
RCO: Ok (creature retrieved from previously created file)
ResMan-hooks (using the new exists/demand methods): Ok (tested for 2da file)
NWScript interactions from default TestRunner: All ok - However, I noticed that the effect returned from getEffects, does not have the same effect id as the originally created effect. I don't know if this is a bug or not (the test case is from the standard TestRunner functionality).
getObjectType, getName, get2DAString, effectDeaf, getEffectId, applyEffectToObject, getEffects, getArea, getObjectsInArea, getFactionMembers, getPosition, getObjectId
Additional NWScript interactions: All ok
getWaypointByTag, getLocation, createObject
I don't have a test at hand for specifically testing the Scheduler functionality, but for the other tests, all seems fine! |

Okay then!
Patch is merged upstream and a supposedly-working version can be grabbed off IC if you don't want to build yourself.

this looks like it cant find the testrunner class. make sure classpath is correct (check if running in a chroot)

Looks like there was a typo, but correcting it didnt fix it.
I had
classpath="/home/ubuntu/jar/org.nwnx.nwnx2.java.jar"
When the filename is actually:
classpath="/home/ubuntu/jar/org.nwnx.nwnx2.jvm.jar"
Im not an expert with Ubuntu, I did recently convert this ubuntu server from a paravirtual to hypervirtual, and one of the commands I did during the conversion was chroot - but I don't use chroot during normal operations - unless it gets done automatically during startup??

Is there dependencies I need to worry about?
Does the jar file need to be with specific permissions?
I am executing the startup script with sudo - so permisions I would think are satisfied.
I also applied +rwx to the jar file. |

Never EVER run nwserver as root. This cannot be overstated.
Try without and see if the jvm then wants to load your jarfile. If not, make sure the path is correct and you aren't running in a chroot.

Yeah - I just do sudo anytime I need to debug permissions etc
I have it running as the default ubuntu user
This machine runs in AWS anyway, so its completely disposable. |

So got the module up and running.
I am just confused about how one goes about writing functionality in Java and invoking it from nwn.
Also
I see that a ruby script creates NWScript.java from NWScript.nss
Is it possible to add extra include files to the generation, so my own custom include files have Java equivalents?
Would I need to edit fids.rb (to add my method to static IDs)
And then add my method declarations to NWScript.nss or something?
Somehow I dont think that would work- I don't think it would be able to resolve the method definitions?
At the moment I would settle for a short guide on how to actually call Java from within nwn or vice versa.
Eg: Pull a lever, call some Java.
Is it possible to get return values into nwn?
Oh... wait - hold on
I see whats going on now:
Its designed so the whole nwn experience is done in Java.
No returning to nwn, because its intended to be a fully fledged replacement for nwscript.
Thats why the lower level methods are all done in Java, so authors can then rebuild their include files completely in java.
Then they can interact with their nwn objects from inside java, but they still remain within the java context.
I have a module with a single creature in an area:
The test runner class does not seem to be firing any events for that creature:
I would assume that heartbeat or on-spawn would be firing at least?
This is my jvm log:

You can't invoke nwscript functions from the outside, at least not yet.
Compiled functions are just bytecode in ncs files, and they don't carry symbol information. Additionally, includes don't get compiled into object files but are inlined into whatever script uses them.
The only way to do this right now would be to create wrapper functions or scripts and call from from the JVM side with ExecuteScript() or similar. This is obviously quite ugly and I really wouldn't recommend it.
nwnx_jvm isn't neccessarily designed to completely replace nwscript, this is just a limitation that still exists until someone foolish enough comes along to write a parser/transpiler from nwscript to java so you can at least generate includes without rewriting them by hand.
Calling into JVM is easy - see JVMEVENT() (or similarily named, I forget) to trigger a event in nwnx_jvm. Calling out is easy too, but you need to marshal it into the main thread with Scheduler.assign() or similar (unless you already are inside a event). This is a thread-related restriction that prevents you from breaking the VM stack.
The Testrunner class depends on a module calling any event like this, otherwise nwnx_jvm never sees any activity.
| Baaleos wrote: | Would I need to edit fids.rb (to add my method to static IDs)

fids.rb references builtins - that is, script commands the VM exposes that do actual stuff inside nwserver. You can't change or amend that list and just have it work. It has nothing to do with includes written in nwscript.

Ah, I get it now - sorta
JVM_EVENT(string ev, object caller = OBJECT_SELF);
This called from nwscript would be the entry point into the Java universe.
I did notice that the NWScript.java does not get a 'getModule' method.
Was this intentional?
I suppose its easily resolved from nwscript :
JVM_EVENT("EntryPointToMyAwesomeJavaFunction",GetModule());
Out of curiosity - Since the JVM persists for the runtime of the nwserver process, I assume accessing static objects etc should be persistent between calls etc
eg: Setting a static bool to be true, then 30 minutes later, it should still exist as a bool. |

Module is ALWAYS object ID 0, so there was no point in making you go through a roundtrip. You can just do new NWObject(0) or similar. I think the library already defines this somewhere but I might be wrong. :)
static variables persist as long as the JVM GC doesn't reap them, yes.

The information goes on extensively -
It is a sporadic crash onMod load
(I am calling JVM_EVENT on the mod load script.
Sometimes it works, other times it results in the above crash.
