Theory is when you know something, but it doesn't work. Practice is when something works, but you don't know why. Programmers combine theory and practice: Nothing works and they don't know why
انا اتكلم داخل صفحة JSP و لدي الصلاحيات المناسبة للقراءة من الموقع المحدد

No!! you shouldn't use the "File" class you should use HttpURLConnection or class URL, i am sorry i am in a hurry but let me give you a hint, i remember i used something like Encoding URLs or something, but using FILE will not work for you
sorry my pc is no arabic enabled
اخواني الاعزاء سوف اشرح لكم القصة كاملة لقد كتبت برنامج JSP وظيفته انه ياخذ محتويات مجلد (في داخله صور فقط) ويعرض في الصفحة جميع هذه الصور مهما كان عدد الصور الموجودة داخل الملف و هذا الكود يعمل على ملف مجلد اححده انا في جهازي الكود سهل و مفهوم:
<%
File dir=new File("D:/tomcat4/webapps/ramyws/images");
String[] images=dir.list(); // Returns a list of the files in the folder
int i=0;
while (i<images.length)
{
String name=(dir.getPath()+"/"+images);
%>
<p align="center">
[img=<%=name%>]</p>
<%
i++;
}
%>وكما لاحظتم فان المجلد المطلوب هو داخل جهزي اي ان الكلاس File يقبل هذا الباث و لكن انا اريد ان ياخذ المجلد و المعلومات عن ماذا بداخله من الويب و ليس من جهازي اي كالتالي:
<%
File dir=new File"http://somesite.com/somefolder");
String[] images=dir.list(); // Returns a list of the files in the folder
int i=0;
while (i<images.length)
{
String name=(dir.getPath()+"/"+images);
%>
<p align="center">
[img=<%=name%>]</p>
<%
i++;
}
%>هل فهمت قصدي...... ارجو المساعدة

استخدم ../
او اكتب موقع ال JSP المستدعاه و موقع الصور حتى استطيع مساعدتك ان امكن
للاسف لا المشكلة اكبر من هيك و معقدة رح اشرح القصة من اولها لذا رح اقطع الخط الآن و اكتبها و اعود و اضعها لتراها.

alssalam alakum,
How are you. Insha allah be kair?
There is a security issue as I understand here, and what you need to do is create a URL constructir using getDocumentBase plue your files to be able to access these pictures.
As I understand your problem is that you want to access pictures in a directory dynamically and display whatever in that directory of pictures dynamically.
If that is the case there are many solutions to your problem .
I have been busy lately at work and life in general but I will get back with you with a sample code to duplicate your solution.
Fi aman illah
Sorry for the English,I am at work and can't type arabic.
الله يعطيك العافية اخي العزيز bawazeem بعد زمان افتقدنا لك و لله
انا بنتظارك اخي و شكرا لك جزيل الشكر
