I am trying to create a executable jar file from the eclipse.. I have 3 classes in java package, in that one class is main class and other 2 classes contains some methods which are there in the main class. I have checked in the online and created a jar file but it is not executing the output from the other class methods.. how I know is I ran the same in eclipse and it is giving output but when I running it from the executable jar file it is not executing the methods of other classes. so can some one please help me to create a jar file.
I have created a jar file by following the steps in this site https://www.java67.com/2014/04/how-to-make-executable-jar-file-in-Java-Eclipse.html
when user click on the Generate button it will start the execution of method which is in the same class, and inside that method I'm calling the other class method.
Method
public static String generateOutput(String url, String tagName) {
XpathUITest output = new XpathUITest();
try {
return output.xpathBuilder(url, tagName);
} catch (IOException | InterruptedException e) {
return "Failed with exceotion, please try again";
}
}
Generate button execution code
