i have a jsp file which collects the students details.
when i click the submit button it should access a java file which calculates the total and average and display it in another jsp file.
i don not want to view the java file. when submit is clicked on the first page it should directly go to another java page( to view)

can any one give me a small example code of the three files.

thanks in advance

hi eric,
not yet..
i have to do it.

hi eric,

yes, it would fail me...
is this expression ok

to check both alpha numerals.

or is there a fundamental mistake i'm making???

thanks in advance

i'm trying to validate only numbers in one input text and to validate only alphabets for another text.

here is the code

i'm getting the input in a text box.
i'm declaring var alpha = /[a-zA-z]/; to specify the a-zA-Z
i might be declaring something like var numb=/0-9/; for numbers.

some text box should get only text and some should get only numbers.
to get only numbers i tried,

stud is the name of my form.
when i run it shows NaN in the output text boxes which should show sum and average and not the alert box.

any help please.

i have a java swing code with not an iota of issues.( it has 2 panels and components in that panel. one north panel, one is south panel. the south panel has only one JLabel).
i have converted that into applet.

now the south panel which is supposed to sow the status messages is only partly visible ( for example, if it has to show registered : it will only show regis.... ) when i resize the window (when run from the IDE it will be fine. everytime i have to do this when i restart the applet. running from ide does not matter. while running from browser too it has the same problem but it wont be fixed with resizing the browser.

what might be the problem
thank you in advance

hi all,

i found the solution

i removed

as the error shows line 67 in, ( it was where i call another class which has the name of the actual dll).
was in line 225, instead of this i replaced it with the line 67( i cut and paste here in line 225)

it solved the problem.

thank you

i have an applet code which uses dll file.
when i run the applet in the client, it should download a file from the server and store in a dir called sip in the c:\
( if the dir is not present, it should create a dir named sip ----- so it will have c:\sip )

all the above said is working fine.
now i have to set c:\sip as the java. library.path for the client machine.

so i used the following lines in my code

but it did not work,
it is showing the following error message

what should i do..

any suggestions please..

thanks in advance
