I have a jsp page where I have embedded a video.Now I want a link to appear ,(after the video is played at least once) for the user to navigate to another jsp page. How will I do it? I have used <EMBED> tag to add the video to the jsp page

I started using the jquery validation plugin but I am facing the folloe=wing problems
1)I have 1 text field("flno") and 2 select boxes("src" and "dest") ,now if I select the "flno " I dont need to use the other select boxes ,else the select boxes become mandatory.
2)What shall I do to check that the values in select boxes are never equal,is there something like notequalTo rule?

I did the following
function validateForm() { var x=document.forms["f1"]["fl_no"].value; var y=document.forms["f1"]["src"].value; if (x==null || x==""||y=="???") { return false; } } </script>
<form name="f1" method="post" action="Test" onsubmit="return validateForm()"> <table> <tr><td><input type="hidden" name="request" value="insert"></td></tr> <tr><td> No.</td><td><input type="text" name="fl_no"><div id=""></div></td></tr> <tr> <td> Select</td> <td> <select name="src"> <option value="???" style="color: gray;">from</option> <option value='IXA'>A </option> <option value='AMD'>B </option> <option value='IXU'>C </option> </select></td></tr> <tr> <tr><td><input type="submit" value="SUBMIT"></td></tr> </table> </form>
But How will I print an error message right next to the text box and select box(if any of them is null)?

I have a html form ,where I have text fields and select box .now I want to do the following:
If any of the fields is null then an error message will be shown beside the fields which are null(and not on a alert box) .How will I do it?

@chris webster thanks a lot..

i have used the following in <input name="demo1" id="demo1" type="text">,now request.getParameter("demo1") fetches null!!

In a html form I have wrritten this,<input type="text" id="demo">,Now if I use the method request.getAttribute("id") in the servlet I get a null value.Why is that?
How can I use "id" attribute declared in a html form ,in a servlet.Or is it the case that only getparameter will work with name attribute

class A { static void p(){System.out.println("h1");} void p1() {p();p2();} void p2() {System.out.println("h2");} } public class Demo extends A { static void p() {System.out.println("h3");} void p2() {System.out.println("h4");} public static void main(String[] args) { new Demo().p1(); } }
The output of the code is h1 h4;so,the p1 method calls parent class's P() method and child class's P2() method.Which I feel is very confusing.What is the general concept?

I have a trigger which fires before the insert and delete operation on a table,and before insertion the no of employees column(per department) will be increased by 1,before deletion the no. of employees column is going to be decreased by 1;
create or replace trigger t1 before insert or delete on empdept for each row begin if inserting then update empdept set noe=noe+1 where empno=:OLD.empno; elsif deleting then update empdept set noe=noe-1 where empno=:OLD.empno; end if; end
but the problem is if I try to delete or update I get the error
*
ERROR at line 1:
ORA-04091: table SCOTT.EMPDEPT is mutating, trigger/function may not see it
ORA-06512: at "SCOTT.T1", line 5
ORA-04088: error during execution of trigger 'SCOTT.T1'.What to do?

I am using eclipse indigo to run my java files.The codes run properly but when I try to see the class hierarchy I get the error "Rt.jar Has No Source Attached" .So,I googled and did the following:I tried to go in Windows and preferences and set the jdk path..even then it would not work.What to do now?

Hi! all,
I want to learn developing Android Apps.What book should I start with?I was thinking about buying a couple of books :Learning Java For Android Development(to brush up my java ) and Head First Android Development.Is it a good choice.?
Thanks in advance..

removeElementAt() method is available in vector class so,its also available to stack class ..but using this method any element can be eliminated..which cannot be a proper implementation of stack... or is it?

public static void main(String[ ] args) { int x = 5; while (x > 1) { x = x + 1; if (x < 3) { System.out.println("small x"); } } the above code prints small x once..why??while loop is a infinite loop and if condition never gets exected.but still i got the output?!!
