driver main is in another class.

this is the error i get while compiling, in emai.java code :


error: method postMail in class emailprocess cannot be applied to given types;

any help would be appreciated.

[Norm]

Can you post the full text of the error message that shows all the info from the compiler?

[steelshark]

lala.postMail(receivertext,sendertext,smtptext)
You are passing in Arguments of the type Jbutton into a method that expects Strings...

[brrrr]

this is the only error i get :

error: method postMail in class emailprocess cannot be applied to given types; line 121

[brrrr]

actually i am passing arguments of type JTextField.

[Norm]

Can you post the FULL text of the error message? Do not edit out parts of it.
Here is a sample:

TestSorts.java:138: cannot find symbol
symbol  : variable var
location: class TestSorts
         var = 2;
         ^

The postMail() method takes String arguments. What are the types of the args you are passing it?

[brrrr]

Sorry for abandoning post~ problem solved already, regarding try and catch.
