Problem with sending emails using JavaMail (ClassFormatError)

Hello.

I want to send e-mail through my app. I don't use any server application, I'm just compiling it with Netbeans.

User should fill the form and press the "wyslij" button, then the subject, "from who" and message goes to constructor of "wyslijEmail" class and it should send the email with those 3 variables.

This is my form (this is only a part of app - and sorry for non english names of methods and variables):



And here is the class which is responsible for sending e-mails:


When I press the wyslij button ive got an error:



I was looking something in google, but i found only answers to add dependency to pom.xml (in maven), but I don't use it so I can't add it there... I have also check that under Eclipse but it throws still the same error. Please give me a tip how to resolve that problem.

Umm nevermind now ! I found the solution. The problem was with javaee jars in class path. When i removed it the problem is gone.
 
It is sorta covered in the JavaRanch Style Guide.
