I created a jdbc connectivity project that i wanted to transfer from my laptop to another. I successfully transferred the mysql databases but on transferring the java file i get the error 

    Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

BUILD SUCCESSFUL (total time: 8 seconds)

on clicking (PRO.java:8) It takes me to the code 

       jLabel2.setIcon(new javax.swing.ImageIcon(getClass().getResource("/PIC/STORY13.jpg"))); // NOI18N

on clicking (PRO.java:8) It takes me to the code 

        public PRO() {
    initComponents();
    this.setLocationRelativeTo(null);//
}

on clicking (PRO.java:156) It takes me to the code

       public void run() {
            new PRO().setVisible(true);
        }

PS: the whole jdbc project works on my laptop perfectly. But on doing the transferring again , the same error pops up.

  • I would start by looking what the PRO class in line 80. And I would rename the class to have a meaningful name. And I would not expect that anybody could help me with a code problem without showing code (see [mcve]). – GhostCat Jan 03 '19 at 06:17
  • @GhostCat i have done what you said.. you can scroll down . Please do tell me what is wrong! i have to submit my project next week. – Namita Geo. Jan 16 '19 at 19:35
  • You already got an answer: most likely, `getClass().getResource("/PIC/STORY13.jpg")` returns NULL, leading to NPE. so: that resource lookup fails on that other platform. Exactly like the answer you got 13 days ago suggests. Beyond that, honestly: you come back after 13, and now you are in a hurry? The help center explicitly states that people should be around when asking questions. It isn't exactly polite to drop a question, and to then walk away for multiple days. Hint: if your priorities are that tight ... then follow them up on time, and not 5 minutes before the assignment is due. – GhostCat Jan 16 '19 at 20:05

This is not due to any jdbc problem, this is because it's looking for some image you used in your project that is missing from the machine you transferred to.
