NoSuchMethodError for PickTool method

[landon.silla]

I ran into a small bug in my application. Here is the stack trace:

Exception in thread "J3D-BehaviorScheduler-1" java.lang.NoSuchMethodError: javax.media.j3d.BranchGroup.pickAll(IILjavax/media/j3d/PickShape;)[Ljavax/media/j3d/PickInfo;
	at com.sun.j3d.utils.pickfast.PickTool.pickAll(PickTool.java:377)
	at pointCloudTest.PickMeasureBehavior.processStimulus(PickMeasureBehavior.java:82)
	at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:174)
	at javax.media.j3d.J3dThread.run(J3dThread.java:250)

Here is the code that is causing it (in file PickMeasureBehavior):

MouseEvent event = (MouseEvent)events[events.length-1];
pickCanvas.setShapeLocation(event);
PickInfo[] allPick = pickCanvas.pickAll();

With the last line being like 82.

What's going on here? This (PickTool (Java 3D 1.3.2)) shows the method exists and it's been there since version 1.3.2 which is super old. I'm developing this on a mac in eclipse and it is all compiling correctly.

I'm a passable java programmer. I mostly do web application work (php), so my skills aren't great for java. It seems this is hopefully an easy question ... if you have, at least, modest java skills. Can somebody help me here?

is is possible the version of picktool you are using in eclipse is somehow different than the one that is actually being found on the classpath at run time. For example, it might be an older version of this jar file is being accidentally found and used instead of the one you intend to use.

Try printing out the system property "classpath" by dumping system properties,
e.g.

public static void dumpSystemProperties() {
        
        Properties p = System.getProperties();
        Map<String, String> sortedProperties = new TreeMap<String, String>();
        for (Object key : p.keySet()) {
          sortedProperties.put(key.toString(), p.getProperty(key.toString()));
        }
        for (String key: sortedProperties.keySet()) {
          System.out.println(key  + ":" + sortedProperties.get(key));
        }
    }

Ok, I did that and printed it below. It's all pretty Greek to me. One other thing to note: This seems to be a Mac only problem (I'm developing this on a mac). I have this as a live product on my website and it runs fine on a pc, but when I run it on a mac, it always breaks like this. That seems weird to me, isn't java, pretty much platform independent? Why would it break on a mac and not on a pc? (Yes, both environments have sufficiently high versions of java)

ok, so the java.class.path one,

java.class.path:/Users/landonsilla/Sites/3dviewer/bin:/Users/landonsilla/Library/Jars/j3dutils.jar:/Users/landonsilla/Library/Jars/j3dcore.jar:/Users/landonsilla/Library/Jars/jnlp.jar:/Users/landonsilla/Library/Jars/vecmath.jar

we see contains

(looks like the your project folder classes)

/Users/landonsilla/Sites/3dviewer/bin


and the .jar files:

/Users/landonsilla/Library/Jars/j3dutils.jar
/Users/landonsilla/Library/Jars/j3dcore.jar
/Users/landonsilla/Library/Jars/jnlp.jar
/Users/landonsilla/Library/Jars/vecmath.jar

So, is eclipse using these same jar files in this path (e.g. in your workspace). ?

Though I was looking into this javax.media.j3d package a bit more, I didn't realize this is built into the Java runtime now.

: Class BranchGroup

It is possible since this API might be in some kind of beta mode, or that the Apple folks have not gotten around to fully implementing or supporting all of the stuff in this API, Since you mentioned it is Apple specific.

Though you also appear to be running the lates 1.6.0_22 Java VM, so It might be we just have to wait until Apple issues an updated Java VM, or if Oracle ever starts to build Java VM for Mac OS.

I also use a Mac, and this kind of different Java VM bugs me sometimes too, I have problems with Javax.media Audio and RTP video API as well.

[travishein]

and, another idea, if it is possibe to somehow find a .jar file of this javax.media.j3d API on its own, like a stand alone .jar file release, it might be possible to shove this into your classpath... e.g. Download j3dcore.jar : j3dcore.jar*«*JKL*«*Jar File Download

Yeah, that's what I've been presuming as well. You said that I should take a jar and put it in the classpath? Well aren't I doing that:

/Users/landonsilla/Library/Jars/j3dcore.jar

I have two main questions, (1) How do I get this to work in my eclipse build and (2) How do I bundle the jar so that I can serve it to everybody and it will work (pc's and mac's)?
