opening jar files on pc prepared by mac

willemjav · #1 (**permalink**) 09-20-2008, 07:38 PM

This jar file works perfect on mac (takes a little while to open)

Why it won´t work on pc (java should be platform independent)

Is the link correct?
Every time I tried to d/l it I get a bad file.

Your link seems to point to this HTML page vs a jar file.

Here is the error message I get when I try to open your jar file.

Here's a scan of the jar file looking for referenced classes. My program found 5 referenced classes that were not found in the jar file. You must have another jar file with those classes
Also you might want to add a Class-path: entry to your manifest file.

willemjav · #5 (**permalink**) 09-20-2008, 09:11 PM

thanks norm, that is very helpful
The class that set the midi drivers has the following import
import de.humatic.mmj.*;
there probably lays the problem!
you have to include the following
mmj - Mac OS X universal binary java Midi subsystem
How should I do the things?

If the missing classes are in another jar file, you need to have both of them available to execute the program. By adding the above entry to the jar file and having the jar files in the same folder, the java program should find the missing classes.

If forgot to post all the results of the jar file scan. My program thinks that the following classes are NOT used.

there was indeed an other jar missing

Norm · #8 (**permalink**) 09-21-2008, 01:38 AM

To merge the contents of two jars, you need to have all the class files extracted from the jar files and then execute the jar command to include all those files in the new jar file.

jason wang · #9 (**permalink**) 09-21-2008, 06:24 AM

I think you don't have a lib in your pc. Maybe it is because that you have this lib install in your mac computer, but you don't have it in your pc computer.

willemjav · #10 (**permalink**) 09-21-2008, 06:41 PM

Jason wang you are right.
The lib is called libmmj.jnilib and there is also a jar called
mmj.jar
You can find both as a download at mmj - Mac OS X universal binary java Midi subsystem
The instruction says that you should put both files at

To make mmj available to all Java applications simply drop both mmj.jar and libmmj.jnilib into /Library/Java/Extensions.

Which I did on my MAC.

But what should I do on a PC (where I put that stuff) or are these fills mend only for PC?

See also de.humatic.mmj.*; (probably the mmj component is for MAC only?)

Norm · #11 (**permalink**) 09-21-2008, 08:36 PM

I downloaded the .zip file and extracted the .jar file and the libmmj.jnilib and tried to execute your code. I get an error saying it can NOT find mmj(.dll). If you remember, I mentioned that to you and Nick very early on in this project and got no answer regarding where that file was located. As far as I know, windows does not recognize or use .jnilib files.

Here's the stack trace from my execution attempt:

I believe I need a mmj.dll file to execute your program on Windows.

willemjav · #12 (**permalink**) 09-22-2008, 01:10 AM

sorry, norm
I spoke to the creator of the midi driver
mmj is only for mac
so I took all mac stuff out of the driver class
and stayed with the sun stuff
here is the new link with jar
this might work on pc, let me know

The GUI framework is fixed,
that runs on several threads (waiting notifying).
But as soon as you start the sound tracks (you need a fbo-1 synthesizer module connect with a midi interface to hear sounds) the old pascal component kicks in which has still many loops that cause your CPU to cook up.
Eventually I might fix that as well.
why there is still this de/humatic/mmj/MidiSystem component
I do not know for the moment.

willemjav · #15 (**permalink**) 09-22-2008, 02:06 AM

found it, the line at the midi driver close
de.humatic.mmj.MidiSystem.closeMidiSystem();
should be out of the pc code.

willemjav · #16 (**permalink**) 09-24-2008, 12:20 AM

I application can be opened on a PC and the midi problem of no sound coming out is solved.
But trying it out I notice the application goes very but very slow on pc,
why is that so?
Unfortunately my web server is down, is there a way to att. the new jar here?

Try using the -Xprof option with the java command. It will generate statistics showing where the code is spending its time when executing. Post the results here so we all can see.

Quote:

very but very slow

Might be your useless loops.

willemjav · #18 (**permalink**) 09-24-2008, 12:27 AM

the loop is out changed into a wait notify clause
-xprof where is that... only have jvm on pc

willemjav · #19 (**permalink**) 09-24-2008, 12:29 AM

can not email the jar so you could see to problem
can´t link to my web page for the moment

willemjav · #20 (**permalink**) 09-24-2008, 01:07 AM

I noticed that the wait/notify clause which waits for each pedal trigger, shows little cpu activity on mac. But after hitting the pedal and going into a new sound track augments the cpu rate dramatically.
I decided not to fix the soundblocks.... one should except that an oldtimer from the 60th consumes a lot more gasoline!
