Ok, I am trying to build a jar file and I cannot seem to find my way around. I have attached an image to this thread to show my directory structure.
Now, I am navigating to my MultiProjectManagement directory and creating my manifest.txt file with:
echo Main-Class: multi.project.management.panels.ProjectListPanel > manifest.txt
Then, I am doing this:
jar -cvfm MPManagement.jar manifest.txt bin multiProjectManagement lib
The jar file is being generated, but when I java -jar MPManagement.jar, I get an error saying:
could not find or load main class: multi.project.management.panels.ProjectListPanel
I understand that my main class is inside bin directory. Now, from what I found online, I hoped that navigating to bin and putting my database, that is multiProjectManagement, and lib folders in bin, and generating the jar file as above would solve the issue, but in that case I am getting a null pointer exception as my program can't find EmbeddedDriver class from derby.jar.
Can someone please guide my how I can create my jar file and make sure it finds my main class, or my EmbeddedDriver class from derby.
