i am currently working on a project , using my netbeans IDE , but i can only run the application on my netbean , it doesnt work when i BUILD it into Jar , it gives no error thou , Thats why i need help of a java programmer that has deployed a database driven application before to help me with this shit .
Thanks in advance

Exactly what do you need help with. What's kind of errors is it logging?

no error ,
this is what happens, on my IDE , the application to launch a registration GUI form for the first time of application launch which had to check the database of EMPTY to determine if it has to show a login GUI if the user has regsitered before,
This works fine on IDE but when i build it as .jar file ,
if i launch it, no GUI is displayed , it does nothing probably coz it couldnt communicate with my database .
i think somthing shhould be done if deploying a java application that uses database .
pls help coz i look google and i couldnt find solution
Thanks

If you think the reason the form is not showing is because the application is not communicating with the database, don't you also think an exception would have been thrown? How did you handle exceptions in your application?

nope , all my exceptions are correctly worked with , i damn sure nothing is wrong with my coding , The application will working very well when " RUN " without building/deploying as .jar file ,

Guy, you said you think the issue is as a result of the application not communicating with the database when deployed as a JAR. Now, my question to you is, don't you think if this is the issue, that an exception would have been thrown? Yet you said there are no exceptions/errors. What does that tell you? Assuming you handled exceptions well, then it means the issue is not because the application cannot communicate with the database.

QED.

OK. I'll give you just 1 blind tip (as I am really groping in the dark here):

Make sure all the required libraries (jar files) are in the class-path (on Windows, check that the environment variable %CLASSPATH% includes all the jar files delimited by semi-colon). One of such is definitely the MySQL JDBC driver. I don't know the rest.

Am not getting solution to my problem here can someone just tell me how he/she deployed a DATABASE driven software (MYSQL), I will see how i can grab from that ,
Thanks so much

Take @logica's advice, build your jar and when running the app use something like this :

java -cp mysql.jar;myapp.jar net.segsalerty.AppStart

run the above in command line window (don't use java -jar or javaw, else you might miss the errors).

i said i used NETBEANS so that my GUI will be easier for me to design , its works perfectly when i run it on my netbeans, How do u want me to export shits from my netbeans and start recompiling on CMD?

My application is working as i do want it on netbeans , perfectly OK !
Am talking about deployment here.
Pls , i need someone that has deployed JAVA application that comm with MYsqL before to share his/her experience of deployment and how he/she did it pls, SIMPLE !

@segsalerty you're not listening ,
i'm also talking deployment. The java command runs your app, it doesn't compile it.

Since you won't be using Netbeans to run your app in production, you either have to run it from the command line or use an executable jar.
the method i suggested is best, until you work out all the chinks in the app.

You have to create your jar file and place it in your classpath , with the mysql driver jar.

Is anyone here using Maven  . Things like these are a piece of cake

I agree. Maven will take care of these sort of things. You just need to specify your dependencies and Maven will do the rest.
