Thanks for keeping me on my toes as far as Java goes. Recently I have not been writing as much code as I want and probably small subtle things I may never even think about but may be important for explaining to others could get forgotten if it were not for the continual questions.

mkdirs() did the trick. The directories are all present on my Linux development system. I'm thinking of other changes, so I'll hold off on a push, since everybody who is actively participating on development on Windows has already created the directories. Thanks< Michael for the link and the information. I guess you are our Java guru. John On Tue, Mar 13, 2012 at 09:52:20AM -0000, Michael Whapples wrote:
Here are some notes, you may want to read the javadoc for the java.io.File class http://docs.oracle.com/javase/1.5.0/docs/api/java/io/File.html Firstly how are you creating the directory? Please remember that themkdir() method will not create any required parent directories, if a parentdirectory does not exist then it will fail. Could this be the problem? If it is overcome it either by manually creating the parent directories or just use the mkdirs() method instead (mkdirs() will create any required parent directories for you), bear in mind though mkdirs() even if it fails may have created some of the parent directories, if that is important to know then manually creating the parent directories might be required. The difference between mkdir() and mkdirs() caught out orca developers as well and lead to a similar problem, however as orca is python I cannot compare the exceptions raised. Also I am not sure what the situation is regarding creating the directory names, might you be getting multiple separators? While I think java can swallow these without trouble, you may want to look at options like the constructor File(String parent, String child) which will join the parent path and child path for you. Oh why java cannot have a join method likepython for joining whole lists of parts of file/path names rather than thisconstructor which oly takes two parts. Moving to Java7 would be unlikely to offer anything here I think. Michael Whapples-----Original Message----- From: John J.

So I used a system property to get the file separator. Later I used the File class to create the settings and temp directories. This worked fine with the initial paths. Now the directories aren't created even in Linux, where the paths are much shorter than for Windows. Does Java have a limit on the length of apths or on the number of elements they can contain? Would using Java 7 improve the situation? Thanks, John -- John J.
