Re: app exe get error can't connect db server
Is this a problem with a java program? Normally java programs do not execute from a exe file.
Can you copy the full text of any error messages and paste it here?
If you don't understand my answer, don't ignore it, ask a question.

thanks for your reply
jar execu file in dist folder work fine
i used launch4j to create exe file from jar file it works fine but i install diffrant machine i get error " can't connect db server"
Re: app exe get error can't connect db server
What is the full text of the error message when the code is executed?
Does the program print out a full stack trace when there is an exception? It needs to do that so that error can be tracked down.
Make sure all catch blocks have code that calls the printStackTrace method to give a full trace of the error.
Have you tried to use the jar file that contains the program instead of using launch4j's output exe file?

Re: app exe get error can't connect db server
java.sql.SqlnonTransientConnectionException:Could not crete conection to database server.Attempted reconnect 3 times.Giving up
java.lang.nullpointerException
Re: app exe get error can't connect db server
That looks important. Can you add a call to printStackTrace to all the catch blocks so that the full stack is printed showing where the exception happened?java.lang.nullpointerException
You should copy and paste the exact text of any error messages. Don't type them in from memory.
The API doc for that error says:java.sql.SqlnonTransientConnectionExceptionPlease consult your driver vendor documentation for the vendor-specified conditions for which this Exception may be thrown.
