Hello, I'm implementing an XXE customization as an addon (my_ext.jar) and need to open a file the customized command needs to perform its duties. Reading XXE docs (and sources, thanks again Hussein!), I've found things like xxe-config: URLs, and also the possibility to refer to resources inside JARs using jar:jar_name.jar!/resource URLs.
I'm wondering if there's an URL scheme that resolves to the addons dir (ex: ~/.xxe4/addon on Linux), or any other method to resolve this dir, in a OS-independent way (that is, that will work in all OSes supported by XXE). I can get to the file (inside the addon jar) if I use something like: jar:file:///home/fabman/.xxe4/addon/myaddon/my_ext.jar!/atts.txt but this only works on my Linux system (of course!) and I'd like to know if there's a more "general" way to change to something like: jar:file:/ADD_ONS_DIR/myaddon/my_ext.jar!/atts.txt where ADD_ONS_DIR is this special URL scheme or another XXE variable I can count on. A solution that resembles this: file:/ADD_ONS_DIR/myaddon/atts.txt would be satisfactory also (that is, reference resources that are outside the addon jar, but inside the myaddon/ dir). I was considering adding a catalog file to the addon and use an URI instead, but find this a not so elegant solution. Hope to have been explicit enough, thank you in advance for your accurate and prompt (as usual) answer, and have a nice 2009! -- Fabi?n Mandelbaum IS Engineer
