jar file problem , please help

you know this is the problem , the jar's manifest has a classphath file and i do check inside and its there

it does not complain AT ALL , the program keeps on running and everything but once it comes to sending email , it just does not

i have tried to do one test to see , weather the class works but it doesnt send emails or it does not work at all

what i did is that , i switched my main with the class where it sends emails

and i created a jar file based on that , what happened is the following

the jar file never works , which means , as u said somethign goes wrong and ihave no idea what goes wrong beccause everything is included

its soo wierd this problem ,

and i do agree with u , something is thrown some where and i am sure that i cought all kinds of exceptions

so i am not sure what elese should i catch to knwo whats going on

We need some more specific information to be able to help you.

- how are you trying to run your application, when no in Eclipse?

- what OS are you running on?

- is the class the can not be found one of yours, or one you depend on?

- if is one of yours do a 'jar -tf jarname.jar' (replace jarname.jar with the path to yours) and see if your class is in there

EDIT: If there is a classpath in the manifest, then the JARs need to be in the same folder as the current JAR. Paths are relative. BTW If you are willing to send me your program, with the dependencies, then I would happily take a look. Contact me ina private message.

for more information here is the senario

because i see that you guys are some how lost because i am not providing enough information

so this is a detailed info of the problem

i have 3 classes

1) mybankmain (jframe)

2) mybankbody(all labels and buttons and events included here)

now: within some events in my program ,

it calls a class called.....

3) myEmail

this class imports two things that are comming from an external jar file , so in short , if the external jar file is not available the program would complain

i run this on windows xp (SP2)

now: if this program runs on eclips , it would do everything it is supposed to do and all kind of calculations will be done and emails will be sent on the conditions that i have specified within the program

if i make a jar file on windows , and i run the jar file , the file would work , all functionalities will work

EXCEPT: sending an email

- either my class is not found

- or external jar file is not found which causes my class not to be able to perform its tasks

i did only one test

which is that i switched the main and i made myEmail as a main and i tried to export the jar file

Result: jar file doesnt work

the way i view whatever inside my jar file , i use Winrar and it would view everythign in the jar file and i see that all my classes are included there

if i open my CLASSPATH , i see that there is a pointer to the external jar file

if i open my manifest : i DO NOT see the exrernal jar file in there but i do see that its pointing to my main class

class main : mybankmain

and there is only the version and signiture

i hope all these additional details would help in determining the problem that ihave been trying to solve for 2 weeks now

non no outputs throughout cmd

i went to the file location and i printed name.jar

when i run it , it just runs successfully with no complains

but if i use this command jar -tf name.jar

it just complains about jar not being a command , so i cant run it

thats all i get

--CoolK--a at 2007-7-9 21:16:29 >

i am very sorry but its really disappointing

no it doesnt send an email on the command line ,

when i said it works , i ment as in there are no complains , but it doesnt send an email , its soo wierd this and i am really about to give up and just use eclips

everytime i wanna use this program

--CoolK--a at 2007-7-9 21:16:29 >

i have done that and guess what

here is the senario

}

blah blah

.

.

. <<< it prints this

blah.emailclass(parameters) <<< stops here

}

so it never actually calls that class

or it does but it cant perform anything cause it contains error , as in all the imports in the email class are coming from an external library

s = JOptionPane.showInputDialog(" Please Specify The Reason of this transaction ");

message = message + s +"\n\nFor Any Additional Information Regarding your Account contact\n"+

"zero@gmail.com\n\n"+"Regards\nK.";

// i put a print over here and it works i mean it does whats supposed

//to do

SmtpGmail E = new SmtpGmail (message);

//i put a print over here , it doesnt display it , which means

// creating object E of type smtpGmail has faild because it doesnt even get to this point

E.email();

JOptionPane.showMessageDialog(null, "An identification Email Has been sent to\n"+"blah@hotmail.com");

--CoolK--a at 2007-7-9 21:16:29 >

java is playing fool or i dont know how to use java

try{

SmtpGmail E = new SmtpGmail (message);

E.email();

JOptionPane.showMessageDialog(null, "An identification Email Has been sent to\n"+"blah@hotmail.com");

throw new Myexception();

}catch (Myexception e){

JOptionPane.showMessageDialog(null, e);

}

it doesnt send an email and it doesnt throw any exceptions

i have a question before i test it

the code has been modified but where would it print that ?

because remeber i am using windows and its like a jframe and stuff , is it gonna print it on the screen or should i use option panes?

because when i use optionpane to make the message appear it complains

so how should i make the message appear?

thanks

> make it pop up on the screen?

yes, println commands aren't going to popup in a gui.

Run the jar at the command line like you did before so that you have a console for the message to appear on. Or wrap them in a JOptionPane if you prefer.

i know i checked it but

everythign before the try catch , works and everything gets excuted

and remeber when we tries the println before ? it did print everything

its only when it tries to initialize an object of the email class and the reason behind this is that it doesnt see the library

i just wanna point out that my library is a jar file too

so i dont know how would i make sure that it includes the library

i thinki am a bit confused about the classpath and the menifest

if u dont mind telling me how to make sure that my library is included in the jar file

thanks

--CoolK--a at 2007-7-9 21:26:25 >

this is my manifest:

__

Manifest-Version: 1.0

Sealed: true

Main-Class: MyhomeBank

__

this is my classbath

_

<?xml version="1.0" encoding="UTF-8"?>

<classpath>

i did see the link 5 times and i read it but i am confused because i use windows and not the command line

like i tried to do it this way which is

creating a file called Manifest.txt

i put class phath and i put my libraryin there

then i went to file and export jar

and i selected to include the manifest that ihave created

result: it just added that txt file to my jar nothign else and all the errors are still there

do u have an idea of how to do this using windows?

thanks i preciate all ur help man

--CoolK--a at 2007-7-9 21:26:25 >

yes i am sure man , because it doesnt make sense to have problem in the email in a jar file but inside eclips , it doesnt have any problems and it wouls send emails

again the exception is this

com/jscape/inet/email/EmailMessage

and what ihave in my email class is this

import com.jscape.inet.email*.

now the reason is says that error is this

EmailMessage message = new EmailMessage();

the previous line is in my email class , so obviously its gonna look for this path

com/jscape/inet/email/EmailMessage

but it doesnt exist , because it doesnt see the library that ihave included

let me know what u think about that and till me if i make sense or not

--CoolK--a at 2007-7-9 21:26:25 >

i gave up , been 2 days trying to do this , and there is no way to load this library , or knowing if its really the library or something else

i wish that there is some body who can tell me a step by step way of how to create a jar file application on windows using eclips and making sure that my (jar library) is included in it , so if it doesnt work , id know that its something else but not the library

thanks
