how are the sensor-native artifacts built?

I've got an updated version of the sensor-applet deployed in my local jnlp test setup that loads the nar file from the applet
codebase instead of being hard-coded to

I've got the V1.4.0 goio nars installed in my local jnlp dir and the new sensor-applet loads them instead of getting them from

Now I want to figure out how to regenerate the existing goio-nars from source.

The dependent step appears to be generating: libvernier_ccsd.jnilib (which combines: libvernier_ccsd-ppc.jnilib and

Once I can get this working I want to update this to also generate a jnilib that uses the 64bit goio dylib I created.

I've got sensor-native checked out and run: make all Which display's this on the console:

swig -java -Iinclude -package ccsd.vernier -outdir src/swig/java/ccsd/vernier -o src/swig/VernierSensorDevice_wrap.c

But it looks like there are two files in src/swig/java/ccsd/vernier/ that didn't get updated: and

[sensor-native (master)]$ ls -ltr src/swig/java/ccsd/vernier/
total 112

When I then run: mvn clean; mvn package I get a series of errors like this:

-------- FYI ----------

The test setup is working well.

I'm using this: to both initially populate a jnlp dir with the jars and
deploy a Rack server that runs a lightweight goio temperature grapher.

I'm using bonjour (zeroconf) to share the local server with other Macs I have here:

$ dns-sd -R "GoIO Temperature Grapher" _http._tcp "" 4321
Registering Service GoIO Temperature Grapher._http._tcp port 4321
21:18:39.631 Got a reply for service GoIO Temperature Grapher._http._tcp.local.: Name now registered and active

I'm using this (hacky but useful)
...Ruby script to compile, jar, sign and pack200 and deploy to the jnlp server:

Opening Safari on my PPC MacOS 10.4 system (with the Charles http proxy running) I can find "GoIO Temperature Grapher" listed
under the Bonjour bookmark.

One thing I noticed is that even though I am using a plain applet tag the requests from Java are sending and accept-encoding
header with 'pack200-gzip' -- so the jnlp server is delivering the jars as pack200-gzip archives.

You can see a slightly older version of this code here:
