Urgent !!!!!!!! Please help me
Hi, My JSP contains the following things A text box and a GO button which fetches the result based on the criteria entered in textbox. The GO button has a validation for a blank search criteria and displayes alert message if we press GO without entering anything. But the problem is, if I hit on ENTER, it fetches me the result even if I haven't entered anything in the text box. It does not go through the validation which executes on pressing on GO button.

Re: Urgent !!!!!!!! Please help me
If
this is the page in question then the problem is that you are not calling any of
the methods. Also, you might want to make sure that the jsp page actually
compiles. I dont know what file://out.println(e); is but I'm sure it wont
compile.

Re: Urgent !!!!!!!! Please help me
Hey Ravindra,
One suggestion i would like to give you ..is that
ur .jsp file looks more like a .java file. Eliminate all your java code and
database connections, statements and put them in a .java file. That will make ur
job easy later on...Access database thru a java
bean from a JSP. U should put the java code in a java file and then compile the
java file and call the methods in the java file.
Instead of file://out.println(e); use
System.out.println(" Exception: +e");
Hope it helps.

Re: Urgent !!!!!!!! Please help me
Ravindra,
Since
you're using the <%! directive, you're just declaring methods, not actually
calling them. You need to actually call them.
You should
also be aware that what you're doing is incredibly dangerous. If two
requests hit this page at the same time your output will be corrupt. The
best way is to put this Java code in a real class, but if you must do it in JSP
do this--take out all the <%! declarations.

SV: Urgent !!!!!!!! Please help me
I'm not sure of this but can't you connect it to an javascript event? document.form.onsubmit(myfuction) As I said, I don't know if there is a onsubmit event on the form, but if it is, I would recomend it... Another way to do it is to have the go button make the function call (I't probably how you do it today, i'm not sure) the function returns false if something is wrong and true otherwise... Since the submit always is run (even if enter is pressed) you will run this function. return is used so the submit is canceled if there is something wrong (you don't want to give a error message and then continue) Hoped it helped.. // Jan Areno -Ursprungligt meddelande- Fran: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]For ShriKant Vashishtha Skickat: den 13 december 2001 08:27 Till: [EMAIL PROTECTED] Amne: Urgent Please help me Hi, My JSP contains the following things A text box and a GO button which fetches the result based on the criteria entered in textbox.

Re: Urgent !!!!!!!! Please help me
Not quite sure what you're after but the second will allow the JVM to use a
single String object for multiple references (if there are any other strings
"Tendulkar"). The first will always create a new String object. In that
way the second is a more economical way of creating/referencing the object.
Is that a help?

I think "second will allow the JVM to use a single String object for multiple
references" is like this:
String s1 = "abc";
String s2 = "abc";
System.out.println(s1==s2);
String s3 = new String("abc");
String s4 = new String("abc");
System.out.println(s3==s4);
Result:
true
false

Re: Urgent !!!!!!!! Please help me
Hi All,
1. for (int i = 0; i < count; i++) {
Node cld = list.item(i).getFirstChild();
}
2. Node cld = null;
for (int i = 0; i < count; i++) {
cld = list.item(i).getFirstChild();
}
Which one is more efficient between the two and why.
Thanks,
-ShriKant

Re: Urgent !!!!!!!! Please help me
hello srikanth,
second one is more efficient as in the first case the node cld will
be creating each and every time. So if the count value is larger then that
many times this object will be created.

Re: Urgent !!!!!!!! Please help me
Hi,
I am little puzzled. Let me clear my understanding.
When I say
Node cld = list.item(i).getFirstChild();
am I calling any constructor of the object, if yes which one?
Do we have any kind of copy constructor like C++. If we do then what
is the syntex of that constructor and how does it internally invoked.
Thanks,

Re: Urgent !!!!!!!! Please help me
I did not run your code, but if my memory serves me correctly, you will get
an error on 1 when you re-enter the loop, as the object cld will already
exists.
These questions look very much like those asked on a Java final exam. Are
you getting help from the board for your take home final?
