I'm running Jitter 1.6.2 with Max/MSP 4.6.2 in a Windows XP environment. The Jitter patch I'm using makes use of some JavaScript methods. I would like to invoke the Java methods java.lang.Runtime.freeMemory() and java.lang.Runtime.totalMemory() from one of the JavaScript methods in the patch.

Is this kind of invocation possible? I've looked in the Max/MSP and Jitter documentation and am unable find anything specific to my needs one way or the other.

If anyone has knowledge about the feasibility of invoking Java methods from within a JavaScript method in the Jitter environment, or has knowledge about where to find documentation on the topic, I'd appreciate hearing it.

Despite the similar names, Java and Javascript are very different

beasts. Aside from connect an mxj and a js object in a patch, I don't

believe there is any way to do what you're talking about. In what

kind of situation to you need to do this anyway? You can use the

freepeer() JS method to free a Jitter object if you need to do that.

Thanks. I was a little suspicious that I probably couldn't do what I wanted, but I thought I'd ask anyway.

The team I'm working with has developed a Jitter patch which manipulates Jitter objects within JavaScript. One of the JavaScript methods makes a call to the JS freepeer() method to free an Image object. Under certain circumstances, on some machines (so far only on Macs), large amounts of memory are consumed, eventually causing the machine to crash. The team is suspicious that using the JS freepeer() method may be the culprit. I wanted to use the Java freeMemory()/totalMemory() methods to help debug the problem. These Java methods report on the amount of free memory and total memory available in the system, respectively.

So you *could* describe your system [platform, versions,

etc.] and post a patch that demonstrates the problem

clearly and concisely, at which point someone in a position

to do so might aid you by repairing the source of your
