need a solution, plz...
Hi, guys, i would like to ask you,
It抯 difficult to explain but say i have jsp page:
from_db.jsp
<.code>
<a href=from_db.jsp?parent_name=?PARENT_NAME+?gt; NAME </a>
Path: <a href=from_db.jsp?parent_name=?PARENT_NAME_1+?gt;NAME_1</a> / <a href=from_db.jsp?parent_name=?PARENT_NAME_2+?gt;NAME_2</a> ...
</.code>
Every time i click on NAME (witch is every time different) i need to built a path, whitch is collected from different PARENT_NAMES on the same from_db.jsp. i hope you understood.
Any suggestions? Thanks in advanced.

I assume that PARENT_NAME is a String variable in your JSP scriptlet page.
If you would like to place the value of PARENT_NAME rather than just, +PARENT_NAME+ then you need to change your code like this.
<a href=from_db.jsp?parent_name=?lt;%= PARENT_NAME %>?gt; NAME </a>
> i hope you understood.No.> Any suggestions?- Try again.- Use the forum's code tags
thanks for replay maple_shaft yes yes you are right PARENT_NAME is a String:

Looks like a job for an array and a loop. What exactly is your question?
Should i story every different PARENT_NAME into ArrayList and execute items with the loop every time after i click on from_db.jsp?... link again and again to built a path of different PARENT_NAMES :
PARENT_NAME_1 / PARENT_NAME_2 / PARENT_NAME_3...
Or should i use some recursion function? I have no idea. Thanks
I can't tell from your description whether recursion might be an option, here. What I've understood so far could be implemented like this:
<%
String[][] NAMES_N_PATHS = {
{"name1", "path1"},
{"name2", "path2"},
{"name3", "path3"},
// etc.
};
for (int i = 0;i < NAMES_N_PATHS.length;i++) {
out.println("<a href=\"" + response.encodeURL(NAMES_N_PATHS[i][1]) + "\">" + NAMES_N_PATHS[i][0] + "</a><br>");
}
%>
thank you quitte i'll try that
hi guys again,let me explain my situatuin again, i have a code:
<code>
import java.io.*;
import java.net.*;
import java.util.*;
import javax.servlet.http.*;
import javax.servlet.ServletException;

{
PrintWriter out = response.getWriter();
out.println("<a href=FileWalk?id=12>12</a>");
out.println("<a href=FileWalk?id=13>13</a>");
out.println("<a href=FileWalk?id=14>14</a>");
String str = request.getParameter("id");
ArrayList ar = new ArrayList();
ar.add(str);
Iterator it = ar.iterator();
while(it.hasNext()) {
String a = (String) it.next();
out.println(a);
}
}
}
</code>

Like this, you mean?out.println("<a href=FileWalk?id=12>12</a>");
out.println("<a href=FileWalk?id=13>12 and 13</a>");
out.println("<a href=FileWalk?id=14>12, 13, 14</a>");
as you see if you press '12' you get a string 'a' whitch is '12' , if you press '13' you get string '13'. I need if i press '12' i get '12' , when i press '13' and i would like to receive string '12' and also a new string '13', and if after that i press '14' i would like to see last two strings ('12','13') and also a new one - '14'
fist click:
out.println("12");
second :
out.println("12");
out.println("13");
third
out.println("12");
out.println("13");
out.println("14");
thanks
