I'm getting some very strange error, and I have no idea what can cause 

it. I'm trying to open a file with the following code:

File settings = new File ( Constants.SETTINGS_FILE );

System.err.println ( settings.getCanonicalPath ( ) + ": Doesn't 

Now, if running this from Eclipse, everything works fine, I get the file 

and I can do the operations standing after the canRead() test. But, if 

running the same code from mxj, I get the "Doesn't exist" error. The 

funny is, that the filename returned with getCanonicalPath() points to a 

file in my filesystem that exists! And I'm sure it exists, because the 

same code in Eclipse should point to the same file, I suppose (and also 

because I looked it 100 times in Finder, and there are no misspellings

a-strange-error

If I put the file named in Constants.SETTINGS_FILE to the root folder of 

the filesystem, everything works fine in mxj. So it seems that it's 

seeking for the file in the root folder (if only the file name is 

specified). Now there are two things that I dont understand with this.

1) Before the code supplied in my prior post, there is a part in my 

program that sets the current directory with System.setProperty ( 

"user.dir", newPath ) to the default path of Max with 

MaxSystem.getDefaultPath() (actually I removed the last slash from the 

output of getDefaultPath(), because System.setProperty expects a path 

without the ending slash). So, how is it possible that after this, the 

program tries to get the file from the system root, and not from the 

2) Before I put the file in the root folder, I got the "doesn't exist" 

error message with the canonical path set to the current default path, 

* error: /Users/admin/Music/MaxMSP/Test/settings.xml: Doesn't exists!

Now, how is it possible, that the File variable returned the above path 

by invoking getCanonicalPath(), but actually it was seeking for the file 

I'm not sure if this problem should be really posted to this list, maybe 

these problems are much more related with the java.io.File class. But 

these errors only happen to me when running the class from mxj.

Maybe yes. Actually, I'm setting up the default folder in my object's 

String newPath = MaxSystem.getDefaultPath ( );

newPath = ( newPath.charAt ( newPath.length ( ) - 1 ) == '/' ? 

newPath.substring ( 0, newPath.length ( ) - 1 ) : newPath );

System.setProperty ( "user.dir", newPath );

error ( "Couldn't modify default path." );

I also tried the way you suggested calling this.getParentPatcher ( 

).getPath ( ), but I got a null pointer exception.

Can it happen that the getDefaultPath is not set at object creation time?

Maybe yes. Actually, I'm setting up the default folder in my object's 
constructor, with the following code:

try {
    String newPath = MaxSystem.getDefaultPath ( );
    newPath = ( newPath.charAt ( newPath.length ( ) - 1 ) == '/' ? 
newPath.substring ( 0, newPath.length ( ) - 1 ) : newPath );
    System.setProperty ( "user.dir", newPath );
} catch ( SecurityException e ) {
    error ( "Couldn't modify default path." );
}

).getPath ( ), but I got a null pointer exception.
