Exporting an Eclipse project with jar file into a runnable jar

Question

I have an eclipse project that I am trying to export to a runnable jar. My project uses an external jar. The exported jar works fine expect for the functionality that uses the external jar. I tried the extract and package libraries option.

Is there anything that I should add Thank you in advance :)

Answer 1

did you put external.jar in your libs folder? if not then you must :) and if you you already did this and then you are exporting project then before exporting you should Right click on project --> properties--> java build path --> order and support --> check library which you are using

clean project(fresh build/installation)

it should work
