It's doesn't work.
My project directory structure is:
/home/dany/TESI/projects/WebPhotoGallery/
-- build/
-- src
-- com
-- webphotogallery
-- server
-- category
-- [...]
-- client
-- public
-- tomcat
-- WebConten
(I use Eclipse with Cypal studio plugin)
On servlet, the code for create category directory is:
private static String UPLOAD_DIRECTORY =
"./src/com/webphotogallery/server/category/";
[...]
if((it.getFieldName().equals("categoryBox"))){
String categoryFolder = it.getString();
UPLOAD_DIRECTORY = UPLOAD_DIRECTORY +
categoryFolder;
[...]
where categoryFolder is passed by client with a form.
But when I call setURL() method on client, what URL I put??
http://localhost:8888/com.webphotogallery.WebPhotoGallery/category/categoryName!?!?
not works.
I'm totally disoriented.
Thanks.
Daniele.
