i can't set the mxj classpath for max 6.1.6 (307fb20)(32bit) on my windows 7 (64bit) machine.

with the 64bit version of max 6.1.5 and the 32bit version of max 5.1.7 (44134) the custom classpath works without problems !

the classpaths in all versions are identical.

i need max 6 (32bit). the 64bit version is useless because of compatibility issues.

here is my "max.java.config.txt" located in "C:\Program Files\code\Max 6.1\Cycling '74\java":

cant-set-mxj-classpath-for-max-6-1-6-32-on-win-7-64-max5-max6-64-work

i updated to max 6.1.6 (32bit). - same problem !

the class gets found if its in the same directory like the patch calling it.

so its definitely the classpath not working and i need it with my workflow with eclipse.

how can i fix it ?


could you please help me ???
is this a bug  ???
and if yes is there a workaround ?????
or should i just dump my project ????
THANK YOU !!!!


Have you tried examining the classpath inside mxj to see what's happening? You can do a

The only other thing I can think of is that somehow you're getting two different versions of Java (one for 32-bit, one for 64-) and the 32-bit one is too old to load the binary class format from the code you've compiled. A quick look at
