[java-dev] FileNotFoundException

I can't view your patcher, but first thing would be to confirm that  
the file does indeed exist. Another test would be to try sending  
FileInputStream an absolute path rather than a relative one (i.e.,  
starting with "/" rather than with "./"). You might be able to use  
the max object [absolutepath] to sort that out, almost, and you might  
find [conformpath] useful too, but to start with, just type the full  
path of the file and see if it works. Also, in the Max Java API you  
can do some extra work using static methods from MaxSystem, such as  
locateFile(), maxPathToNativePath() and nameConform(), which is  
probably preferable in general. I can't remember what the current  
directory is for mxj, but it's probably the max folder.
