i already put my bean class file into the common folder. can some one help me to resolve this thank you
*note i shoulld pass in the value from another html form page. i sure that the name that i give to the form field is similar to the jsp getparameter name.

thank you.

regards,
albert

It's String, not string.

I'd also strongly advise you to move your java code out of the JSP page and completely into beans and/or servlets. It'll not only make for a better program structure, it will make debugging 500% easier.

i already change the string to String. but the same error come out how to solve it. i already no idea to solve it. Pleas...Please... help me

Show us the new error messages. if you changed the page they have to have changed.

Alos please use the UBB code tags when posting code examples (see the CODE button on the reply page) to enclose code and preserve its formatting.

error is:

JSP code:

This is Java. That means that identifiers, class names and method names are case sensitive.

Check the APIs and make sure you are using the correct spelling and casing of all elements.

ya i already check and make sure the variable... is ok
but it's still have error.

The method getparameter(String) is undefined for the type HttpServletRequest

You didn't check very well.

I think I've already answered this one in an another forum...

oh no, same forum, different thread called "unable to compile class"

sorry i post two threat for same forum i think you better answer my unable to compile class threats thank you

i solve all the error already. But when i do the testing for my send mail application, the email cannot reach the recipient. here i post my code, if i code something wrong please tell me thank you.

Form Code:

<html>
 
<head>
 
<title>Send Mail Application</title>
<script type="text/javascript">
function checking(){
 
if (document.all.toadd.value==""){
alert("Please fill in the email address to send the message");return false;}

}
</script>
</head>
 
<body background="ricebk.jpg" bgcolor="#FFFFFF" text="#000000" link="#666633" vlink="#333366" alink="#990000">

<p>                                                                  
<input type="submit" value="Send" name="B1">   <input type="reset" value="Reset" name="B2"></p>
</form>
</font>
</body>
 
</html>

this is my form code. i need to go in to this page to do my key in address message body and so on and i using smtp.mail.yahoo.com as my host.

send.jsp

the jsp will call the bean file to send out the message. in the jsp will pass in the relevent information to sending message.

this is the bean file that use to send out the message to the recipient.
