eskimoblood Senior Member Offline Posts: 341	Re: Library import Reply #1 - Jan 31^st, 2007, 8:50am I don't know if it work but I could import it like this: copy the java-synaptics-0.1.jar file in yourProcessingDir/libraries/synaptics/library and rename it to synaptics.jar. I think there is some trouble with the "-" in the name. In your sketch import the jar like this: import net.kano.jsynaptics.*;

thank you for your fast help!!!

now i can access the classes i need. but if I do the following:

import net.kano.jsynaptics.*;
DeviceManager DM = DeviceManager.getInstance();

I get this:

java.lang.UnsupportedClassVersionError: net/kano/jsynaptics/DeviceManager (Unsupported major.minor version 49.0)
at java.lang.ClassLoader.defineClass0(Native Method)

what doeas that mean??? does it mean, processing and the libraries are incompatible? please dont tell me they are

...
thanks alot

JohnG Ex Member	Re: Library import Reply #3 - Jan 31^st, 2007, 10:23pm I think that means that the library is Java 1.5, whilst processing uses 1.4.

peter_lo YaBB Newbies Offline Posts: 5	Re: Library import Reply #4 - Feb 1^st, 2007, 1:48am can i do anything about it? will processing use java 1.5 sometime? i need to use that library!

JohnG Ex Member	Re: Library import Reply #5 - Feb 1^st, 2007, 11:02am You can replace the library processing uses with 1.5 Just rename the java folder int he procressing-0123 directory, and get a copy of the java-1.5 JRE, and put it in the place of the one that shipped with processing (folder must be called "java" not "jre-1.5-1_0_10" or whatever)

Hi all,

I'm having a hard time trying to get the Synaptics Library to work.

No matter which way I import it, I get the same error:

2009-11-17 22:26:06 net.kano.jsynaptics.DeviceManager getInstance
SEVERE: Couldn't load java-synaptics native library
java.lang.UnsatisfiedLinkError: no jsynaptics in java.library.path
(...)

Having read this thread, an earlier one:
http: //processing.org/discourse/yabb2/num_1124.html
129086
and googling the subject, I still can't figure out what am I doing wrong.

I'm using:
Processing 1.0.9
Java 1.6.0_07-b06

I'd appreciate any help with this.
Thanks.

Have you tried the advice in the second message? Just replacing yourProcessingDir by yourSketchbookDir.
Or put the jar in a 'code' folder in the sketch's folder, if you plan to use it in only one sketch.

Quote:

Processing 1.0.9
Java 1.6.0_07-b06

Nice info, but indicating which system you use is useful too...

[EDIT] Well, looking at the link, I see the library is Windows only, so I am answered... But the advice is still generically sound.

Also show what is the path to your sketch and to your library.

PhiLho, thanks for the quick reply.

Yes, I tried all three options:
- main library folder
- libraries folder in the sketchbook
- code folder (through Add file...)
I've also changed the name of the file as eskimoblood suggested.

As for the paths, here's what I get after typing
println(System.getProperty("java.library.path"));

C:\psketches\test01\code;C:\processing\java\bin;.;C:\Windows\system32;C:\Windows
;C:\Program Files (x86)\PC Connectivity Solution;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;c:\Program Files (x86)\Common Files\Roxio Shared\DLLShared;c:\Program Files (x86)\Common Files\Roxio Shared\DLLShared;c:\Program Files (x86)\Common Files\Roxio Shared\9.0\DLLShared;C:\Program Files (x86)\QuickTime\QTSystem;C:\processing\java\bin;C:\processing\java\bin

One more thing:
The package contains two files:
- java-synaptics-0.1.jar
- java-synaptics-native-0.1.jar
Should I be doing something different with the latter?

Thanks again for your help.

ps. my OS is Vista 64bit

Aha, the Vista + 64bit might be an issue. Well, I suppose you have a working driver outside of Processing, right?
But the native part of the library might not appreciate the 64bits. Or Vista. Or both...

I fear I have no experience yet with 64bit systems, so it is pure guess (driven by some base knowledge (lot of reading), though... Cool
